SALT(7)

NAME
salt - Salt Documentation

INTRODUCTION TO SALT
We’re not just talking about NaCl..SS The 30 second summary

Salt is:

•   a configuration management system, capable of maintaining remote nodes in defined states (for example, ensuring that specific packages are installed and specific services are running)

•   a distributed remote execution system used to execute commands and query data on remote nodes, either individually or by arbitrary selection criteria

    It was developed in order to bring the best solutions found in the world of remote execution together and make them better, faster, and more malleable. Salt accomplishes this through its ability to handle large loads of information, and not just dozens but hundreds and even thousands of individual servers quickly through a simple and manageable interface.

  Simplicity

Providing versatility between massive scale deployments and smaller systems may seem daunting, but Salt is very simple to set up and maintain, regardless of the size of the project. The architecture of Salt is designed to work with any number of servers, from a handful of local network systems to international deployments across different datacenters. The topology is a simple server/client model with the needed functionality built into a single set of daemons. While the default configuration will work with little to no modification, Salt can be fine tuned to meet specific needs.

  Parallel execution

The core functions of Salt:

•   enable commands to remote systems to be called in parallel rather than serially

•   use a secure and encrypted protocol

•   use the smallest and fastest network payloads possible

•   provide a simple programming interface

    Salt also introduces more granular controls to the realm of remote execution, allowing systems to be targeted not just by hostname, but also by system properties.

  Building on proven technology

Salt takes advantage of a number of technologies and techniques. The networking layer is built with the excellent ZeroMQ networking library, so the Salt daemon includes a viable and transparent AMQ broker. Salt uses public keys for authentication with the master daemon, then uses faster AES encryption for payload communication; authentication and encryption are integral to Salt. Salt takes advantage of communication via msgpack, enabling fast and light network traffic.

  Python client interface

In order to allow for simple expansion, Salt execution routines can be written as plain Python modules. The data collected from Salt executions can be sent back to the master server, or to any arbitrary program. Salt can be called from a simple Python API, or from the command line, so that Salt can be used to execute one-off commands as well as operate as an integral part of a larger application.

  Fast, flexible, scalable

The result is a system that can execute commands at high speed on target server groups ranging from one to very many servers. Salt is very fast, easy to set up, amazingly malleable and provides a single remote execution architecture that can manage the diverse requirements of any number of servers. The Salt infrastructure brings together the best of the remote execution world, amplifies its capabilities and expands its range, resulting in a system that is as versatile as it is practical, suitable for any network.

  Open

Salt is developed under the Apache 2.0 license, and can be used for open and proprietary projects. Please submit your expansions back to the Salt project so that we can all benefit together as Salt grows. Please feel free to sprinkle Salt around your systems and let the deliciousness come forth.

INSTALLATION

The Salt system setup is amazingly simple, as this is one of the central design goals of Salt.

  Quick Install

Many popular distributions will be able to install the salt minion by executing the bootstrap script:

wget -O - http://bootstrap.saltstack.org | sudo sh

The script should also make it simple to install a salt master, if desired.

Currently the install script has been tested to work on:

•   Ubuntu 10.x/11.x/12.x

•   Debian 6.x

•   CentOS 6.3

•   Fedora

•   Arch

•   FreeBSD 9.0

    See Salt Bootstrap for more information.

  Platform-specific installation instructions

These guides go into detail how to install salt on a given platform.

  Arch Linux

  Installation

Salt is currently available via the Arch User Repository (AUR). There are currently stable and -git packages available.

  Stable Release

Install Salt stable releases from the Arch Linux AUR as follows:

wget https://aur.archlinux.org/packages/sa/salt/salt.tar.gz
tar xf salt.tar.gz
cd salt/
makepkg -is

A few of Salt's dependencies are currently only found within the AUR, so it is necessary to download and run makepkg -is on these as well. As a reference, Salt currently relies on the following packages which are only available via the AUR:

•   https://aur.archlinux.org/packages/py/python2-msgpack/python2-msgpack.tar.gz

•   https://aur.archlinux.org/packages/py/python2-psutil/python2-psutil.tar.gz

Note
    yaourt

    If a tool such as Yaourt is used, the dependencies will be gathered and built automatically.

    The command to install salt using the yaourt tool is:

    yaourt salt

  Tracking develop

To install the bleeding edge version of Salt (may include bugs!), use the -git package. Installing the -git package as follows:

wget https://aur.archlinux.org/packages/sa/salt-git/salt-git.tar.gz
tar xf salt-git.tar.gz
cd salt-git/
makepkg -is

See the note above about Salt's dependencies.

  Post-installation tasks

systemd

Activate the Salt Master and/or Minion via systemctl as follows:

systemctl enable salt-master.service
systemctl enable salt-minion.service

Start the Master

Once you've completed all of these steps you're ready to start your Salt Master. You should be able to start your Salt Master now using the command seen here:

systemctl start salt-master

Now go to the Configuring Salt page.

  Debian Installation

Currently the latest packages for Debian are published in Martin F. Krafft's personal debian.org repository.

  Configure Apt

Setup apt to install Salt from the repository and use Debian's stable (squeeze) backports for dependencies:

for i in salt-{common,master,minion,syndic,doc} sysvinit-utils; do
echo "Package: $i"
echo "Pin: release a=squeeze-backports"
echo "Pin-Priority: 600"
echo
done > /etc/apt/preferences.d/local-salt-backport.pref

  Add repository

Add the repository to the list of sources:

cat <<_eof > /etc/apt/sources.list.d/local-madduck-backports.list
    deb http://debian.madduck.net/repo squeeze-backports main
    deb-src http://debian.madduck.net/repo squeeze-backports main
_eof

Import the repository key.

wget -q -O- "http://debian.madduck.net/repo/gpg/archive.key" | apt-key add -

Note
    You can optionally verify the key integrity with sha512sum using the public key signature shown here. E.g:

    echo "8b1983fc2d2c55c83e2bbc15d93c3fc090c8e0e92c04ece555a6b6d8ff26de8b4fc2ccbe1bbd16a6357ff86b8b69fd261e90d61350e07a518d50fc9f5f0a1eb3  archive.key" | sha512sum -c

Update the package database:

apt-get update

  Install packages

Install the Salt master, minion, or syndic from the repository with the apt-get command. These examples each install one daemon, but more than one package name may be given at a time:

apt-get install salt-master

apt-get install salt-minion

apt-get install salt-syndic

  Post-installation tasks

Now go to the Configuring Salt page.

  Packages from Source

To build your own salt Debian packages on squeeze use:

cat <<EOF | sudo tee /etc/apt/sources.list.d/backports.list
deb http://backports.debian.org/debian-backports squeeze-backports main
EOF
apt-get update
apt-get install build-essential fakeroot
apt-get install python-argparse python-zmq
apt-get -t squeeze-backports install debhelper python-sphinx

After installing the necessary dependencies build the packages with:

git clone https://github.com/saltstack/salt.git
cd salt
fakeroot debian/rules binary

You will need to install the salt-common package along with the salt-minion or salt-master packages. For example:

dpkg -i salt-common_<version>.deb salt-minion<version>.deb
apt-get -f install

The last command pulls in the required dependencies for your salt packages.

For more information how to use debian-backports see http://backports-master.debian.org/Instructions/

  Fedora

Beginning with version 0.9.4, Salt has been available in the primary Fedora repositories and EPEL. It is installable using yum. Fedora will have more up to date versions of Salt than other members of the Red Hat family, which makes it a great place to help improve Salt!

  Installation

Salt can be installed using yum and is available in the standard Fedora repositories.

  Stable Release

Salt is packaged separately for the minion and the master. It is necessary only to install the appropriate package for the role the machine will play. Typically, there will be one master and multiple minions.

yum install salt-master
yum install salt-minion

  Post-installation tasks

Master

To have the Master start automatically at boot time:

systemctl enable salt-master.service

To start the Master:

systemctl start salt-master.service

Minion

To have the Minion start automatically at boot time:

systemctl enable salt-minion.service

To start the Minion:

systemctl start salt-minion.service

Now go to the Configuring Salt page.

  FreeBSD

Salt was added to the FreeBSD ports tree Dec 26th, 2011 by Christer Edwards <christer.edwards@gmail.com>. It has been tested on FreeBSD 7.4, 8.2, 9.0 and 9.1 releases.

Salt is dependent on the following additional ports. These will be installed as dependencies of the sysutils/py-salt port.

/devel/py-yaml
/devel/py-pyzmq
/devel/py-Jinja2
/devel/py-msgpack
/security/py-pycrypto
/security/py-m2crypto

  Installation

To install Salt from the FreeBSD ports tree, use the command:

make -C /usr/ports/sysutils/py-salt install clean

  Post-installation tasks

Master

Copy the sample configuration file:

cp /usr/local/etc/salt/master.sample /usr/local/etc/salt/master

rc.conf

Activate the Salt Master in /etc/rc.conf or /etc/rc.conf.local and add:

+ salt_master_enable="YES"

Start the Master

Start the Salt Master as follows:

service salt_master start

Minion

Copy the sample configuration file:

cp /usr/local/etc/salt/minion.sample /usr/local/etc/salt/minion

rc.conf

Activate the Salt Minion in /etc/rc.conf or /etc/rc.conf.local and add:

+ salt_minion_enable="YES"
+ salt_minion_paths="/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin"

Start the Minion

Start the Salt Minion as follows:

service salt_minion start

Now go to the Configuring Salt page.

  Gentoo

Salt can be easily installed on Gentoo via Portage:

emerge app-admin/salt

  Post-installation tasks

Now go to the Configuring Salt page.

  OS X

  Dependency Installation

ZeroMQ and swig need to be installed first.

Using homebrew:

brew install swig
brew install zmq

Using macports, zmq and swig may need to be installed this way:

sudo port install pyzmq
sudo port install py27-m2crypto
sudo port install py27-crypto
sudo port install py27-msgpack
sudo port install python-swig

For installs using the OSX system python, pip install needs to use 'sudo':

sudo pip install salt

For installs using python installed via homebrew, sudo should be unnecessary:

pip install salt

  Salt-Master Customizations

To run salt-master on OSX, the root user maxfiles limit must be increased:

sudo launchctl limit maxfiles 10000

And add this configuration option to the /etc/salt/master file:

max_open_files: 10000

Now the salt-master should run without errors:

sudo salt-master --log-level=all

  Post-installation tasks

Now go to the Configuring Salt page.

  RHEL / CentOS / Scientific Linux / Amazon Linux / Oracle Linux

Beginning with version 0.9.4, Salt has been available in EPEL. It is installable using yum. Salt should work properly with all mainstream derivatives of RHEL, including CentOS, Scientific Linux, Oracle Linux and Amazon Linux. Report any bugs or issues to the salt github project.

  Installation

Salt and all dependencies have been accepted into the yum repositories for EPEL5 and EPEL6. The latest salt version can be found in epel-testing, while an older but more tested version can be found in regular epel.

Example showing how to install salt from epel-testing:

yum --enablerepo=epel-testing install salt-minion

On RHEL6, the proper Jinja package 'python-jinja2' was moved from EPEL to the "RHEL Server Optional Channel". Verify this repository is enabled before installing salt on RHEL6.

Salt can be installed using yum and is available in the standard Fedora repositories.

  Stable Release

Salt is packaged separately for the minion and the master. It is necessary only to install the appropriate package for the role the machine will play. Typically, there will be one master and multiple minions.

On the salt-master, run this:

yum install salt-master

On each salt-minion, run this:

yum install salt-minion

  Post-installation tasks

Master

To have the Master start automatically at boot time:

chkconfig salt-master on

To start the Master:

service salt-master start

Minion

To have the Minion start automatically at boot time:

chkconfig salt-minion on

To start the Minion:

service salt-minion start

Now go to the Configuring Salt page.

  Solaris

Salt was added to the OpenCSW package repository in September of 2012 by Romeo Theriault <romeot@hawaii.edu> at version 0.10.2 of Salt. It has mainly been tested on Solaris 10 (sparc), though it is built for and has been tested minimally on Solaris 10 (x86), Solaris 9 (sparc/x86) and 11 (sparc/x86). (Please let me know if you're using it on these platforms!) Most of the testing has also just focused on the minion, though it has verified that the master starts up successfully on Solaris 10.

Comments and patches for better support on these platforms is very welcome.

As of version 0.10.4, Solaris is well supported under salt, with all of the following working well:

1.  remote execution

2.  grain detection

3.  service control with SMF

4.  'pkg' states with 'pkgadd' and 'pkgutil' modules

5.  cron modules/states

6.  user and group modules/states

7.  shadow password management modules/states

    Salt is dependent on the following additional packages. These will automatically be installed as dependencies of the py_salt package.:

    py_yaml
    py_pyzmq
    py_jinja2
    py_msgpack_python
    py_m2crypto
    py_crypto
    python

  Installation

To install Salt from the OpenCSW package repository you first need to install pkgutil assuming you don't already have it installed:

On Solaris 10:

pkgadd -d http://get.opencsw.org/now

On Solaris 9:

wget http://mirror.opencsw.org/opencsw/pkgutil.pkg
pkgadd -d pkgutil.pkg all

Once pkgutil is installed you'll need to edit it's config file /etc/opt/csw/pkgutil.conf to point it at the unstable catalog:

- #mirror=http://mirror.opencsw.org/opencsw/testing
+ mirror=http://mirror.opencsw.org/opencsw/unstable

OK, time to install salt.

# Update the catalog
root> /opt/csw/bin/pkgutil -U
# Install salt
root> /opt/csw/bin/pkgutil -i -y py_salt

  Minion Configuration

Now that salt is installed you can find it's configuration files in /etc/opt/csw/salt/.

You'll want to edit the minion config file to set the name of your salt master server:

- #master: salt
+ master: your-salt-server

If you would like to use pkgutil as the default package provider for your Solaris minions, you can do so using the providers option in the minion config file.

You can now start the salt minion like so:

On Solaris 10:

svcadm enable salt-minion

On Solaris 9:

/etc/init.d/salt-minion start

You should now be able to log onto the salt master and check to see if the salt-minion key is awaiting acceptance:

salt-key -l un

Accept the key:

salt-key -a <your-salt-minion>

Run a simple test against the minion:

salt '<your-salt-minion>' test.ping

  Troubleshooting

Logs are in /var/log/salt

  Ubuntu Installation

  Add repository

The latest packages for Ubuntu are published in the saltstack PPA. If you have the add-apt-repository utility, you can add the repository and import the key in one step:

sudo add-apt-repository ppa:saltstack/salt

add-apt-repository: command not found?

    The add-apt-repository command is not always present on Ubuntu systems. This can be fixed by installing python-software-properties:

    sudo apt-get install python-software-properties

Alternately, manually add the repository and import the PPA key with these commands:

echo deb http://ppa.launchpad.net/saltstack/salt/ubuntu `lsb_release -sc` main | sudo tee /etc/apt/sources.list.d/saltstack.list
wget -q -O- "http://keyserver.ubuntu.com:11371/pks/lookup?op=get&search=0x4759FA960E27C0A6" | sudo apt-key add -

After adding the repository, update the package management database:

sudo apt-get update

  Install packages

Install the Salt master, minion, or syndic from the repository with the apt-get command. These examples each install one daemon, but more than one package name may be given at a time:

sudo apt-get install salt-master

sudo apt-get install salt-minion

sudo apt-get install salt-syndic

  Post-installation tasks

Now go to the Configuring Salt page.

  Windows

Salt has full support for running the Salt Minion on Windows.

There are no plans for the foreseeable future to develop a Salt Master on Windows. For now you must run your Salt Master on a supported operating system to control your Salt Minions on Windows.

Many of the standard Salt modules have been ported to work on Windows and many of the Salt States currently work on Windows, as well.

The 64bit installer has been tested on Windows 7 64bit and Windows Server 2008R2 64bit. The 32bit installer has been tested on Windows 2003 Server 32bit. Please file a bug report on our github repo if issues for other platforms are found.

The installer asks for 2 bits of information; the master hostname and the minion name. The installer will update the minion config with these options and then start the minion.

The salt-minion service will appear in the Windows Service Manager and can be started and stopped there or with the command line program sc like any other Windows service.

If the minion won't start, try installing the Microsoft Visual C++ 2008 x64 redistributable.

Make sure that the minion config file has the line ipc_mode: tcp

  Silent Installer option

The installer can be run silently by providing the /S option at the command line. The options /master and /minion-name allow for configuring the master hostname and minion name, respectively. Here's an example of using the silent installer:

Salt-Minion-0.11.1-Setup-amd64.exe /S /master=yoursaltmaster /minion-name=yourminionname

  Installer Source

The Salt Windows installer is built with the open-source NSIS compiler. The source for the installer is found in the pkg directory of the Salt repo here: https://github.com/saltstack/salt/blob/develop/pkg/windows/installer/Salt-Minion-Setup.nsi. To create the installer run python setup.py bdist_esky, extract the frozen archive from dist/ into pkg/windows/buildenv/ and run NSIS.

The NSIS installer can be found here: http://nsis.sourceforge.net/Main_Page

  Installation from source

CONFIGURING SALT

Salt configuration is very simple. The default configuration for the master will work for most installations and the only requirement for setting up a minion is to set the location of the master in the minion configuration file.

master
    The Salt master is the central server that all minions connect to. Commands are run on the minions through the master, and minions send data back to the master (unless otherwise redirected with a returner). It is started with the salt-master program.

minion
    Salt minions are the potentially hundreds or thousands of servers that may be queried and controlled from the master.

    The configuration files will be installed to /etc/salt and are named after the respective components, /etc/salt/master and /etc/salt/minion.

  Master Configuration

By default the Salt master listens on ports 4505 and 4506 on all interfaces (0.0.0.0). To bind Salt to a specific IP, redefine the "interface" directive in the master configuration file, typically /etc/salt/master, as follows:

- #interface: 0.0.0.0
+ interface: 10.0.0.1

After updating the configuration file, restart the Salt master. See the master configuration reference for more details about other configurable options.

  Minion Configuration

Although there are many Salt Minion configuration options, configuring a Salt Minion is very simple. By default a Salt Minion will try to connect to the DNS name "salt"; if the Minion is able to resolve that name correctly, no configuration is needed.

If the DNS name "salt" does not resolve to point to the correct location of the Master, redefine the "master" directive in the minion configuration file, typically /etc/salt/minion, as follows:

- #master: salt
+ master: 10.0.0.1

After updating the configuration file, restart the Salt minion. See the minion configuration reference for more details about other configurable options.

  Running Salt

1.  Start the master in the foreground (to daemonize the process, pass the -d flag):

    # salt-master

2.  Start the minion in the foreground (to daemonize the process, pass the -d flag):

    # salt-minion

Having trouble?

    The simplest way to troubleshoot Salt is to run the master and minion in the foreground with log level set to debug:

    salt-master --log-level=debug

Run as an unprivileged (non-root) user?

    To run Salt as another user, specify --user in the command line or assign user in the configuration file.

There is also a full troubleshooting guide available.

  Key Management

Salt uses AES encryption for all communication between the Master and the Minion. This ensures that the commands sent to the Minions cannot be tampered with, and that communication between Master and Minion is authenticated through trusted, accepted keys.

Before commands can be sent to a Minion, its key must be accepted on the Master. Run the salt-key command to list the keys known to the Salt Master:

[root@master ~]# salt-key -L
Unaccepted Keys:
alpha
bravo
charlie
delta
Accepted Keys:

This example shows that the Salt Master is aware of four Minions, but none of the keys has been accepted. To accept the keys and allow the Minions to be controlled by the Master, again use the salt-key command:

[root@master ~]# salt-key -A
[root@master ~]# salt-key -L
Unaccepted Keys:
Accepted Keys:
alpha
bravo
charlie
delta

The salt-key command allows for signing keys individually or in bulk. The example above, using -A bulk-accepts all pending keys. To accept keys individually use the lowercase of the same option, -a keyname.

See also

    salt-key manpage

  Sending Commands

Communication between the Master and a Minion may be verified by running the test.ping remote command.

[root@master ~]# salt 'alpha' test.ping
alpha:
    True

Communication between the Master and all Minions may be tested in a similar way.

[root@master ~]# salt '*' test.ping
alpha:
    True
bravo:
    True
charlie:
    True
delta:
    True

Each of the Minions should send a "True" response as shown above.

  What's Next?

Depending on the primary way you want to manage your machines you may either want to visit the section regarding Salt States, or the section on Modules.

DEVELOPING SALT

There is a great need for contributions to salt and patches are welcome! The goal here is to make contributions clear, make sure there is a trail for where the code has come from, and most importantly, to give credit where credit is due!

There are a number of ways to contribute to salt development.

  Sending a Github pull request

This is the preferred method for contributions. Simply create a Github fork, commit changes to the fork, and then open up a pull request.

The following is an example (from Open Comparison Contributing Docs ) of an efficient workflow for forking, cloning, branching, committing, and sending a pull request for a github repository.

First, make a local clone of your github fork of the salt github repo and make edits and changes locally.

Then, create a new branch on your clone by entering the following commands:

git checkout -b fixed-broken-thing
Switched to a new branch 'fixed-broken-thing'

Choose a name for your branch that describes its purpose.

Now commit your changes to this new branch with the following command:

#add and commit all changes at once
git commit -a -m 'description of my fixes for the broken thing'

And then push your locally committed changes back up to GitHub:

git push --set-upstream origin fixed-broken-thing

Now go look at your fork of the salt repo on the GitHub website. The new branch will now be listed under the "Source" tab where it says "Switch Branches". Select the new branch from this list, and then click the "Pull request" button.

Put in a descriptive comment, and include links to any project issues related to the pull request.

The repo managers will be notified of your pull request and it will be reviewed. If a reviewer asks for changes, just make the changes locally in the same local feature branch, push them to GitHub, then add a comment to the discussion section of the pull request.

Note
    Travis-CI

    To make reviewing pull requests easier for the maintainers, please enable Travis-CI on the fork. Salt is already configured, so simply follow the first 2 steps on the Travis-CI Getting Started Doc.

  Keeping Salt Forks in Sync

Salt is advancing quickly. It is therefore critical to pull upstream changes from master into forks on a regular basis. Nothing is worse than putting in a days of hard work into a pull request only to have it rejected because it has diverged too far from master.

To pull in upstream changes:

# For ssh github
git remote add upstream git@github.com:saltstack/salt.git
git fetch upstream
# For https github
git remote add upstream https://github.com/saltstack/salt.git
git fetch upstream

To check the log to be sure that you actually want the changes, run this before merging:

git log upstream/develop

Then to accept the changes and merge into the current branch:

git merge upstream/develop

For more info, see Github Fork a Repo Guide or Open Comparison Contributing Docs

  Posting patches to the mailing list

Patches will also be accepted by email. Format patches using git format-patch and send them to the Salt users mailing list. The contributor will then get credit for the patch, and the Salt community will have an archive of the patch and a place for discussion.

  Installing Salt for development

Clone the repository using:

git clone https://github.com/saltstack/salt

Note
    tags

    Just cloning the repository is enough to work with Salt and make contributions. However, fetching additional tags from git is required to have Salt report the correct version for itself. To do this, first add the git repository as an upstream source:

    git remote add upstream http://github.com/saltstack/salt

    Fetching tags is done with the git 'fetch' utility:

    git fetch --tags upstream

Create a new virtualenv:

virtualenv /path/to/your/virtualenv

On Arch Linux, where Python 3 is the default installation of Python, use the virtualenv2 command instead of virtualenv.

Note
    Using system Python modules in the virtualenv

    To use already-installed python modules in virtualenv (instead of having pip download and compile new ones), run virtualenv --system-site-packages Using this method eliminates the requirement to install the salt dependencies again, although it does assume that the listed modules are all installed in the system PYTHONPATH at the time of virtualenv creation.

Activate the virtualenv:

source /path/to/your/virtualenv/bin/activate

Install Salt (and dependencies) into the virtualenv:

pip install M2Crypto    # Don't install on Debian/Ubuntu (see below)
pip install pyzmq PyYAML pycrypto msgpack-python jinja2 psutil
pip install -e ./salt   # the path to the salt git clone from above

Note
    Installing M2Crypto

    swig and libssl-dev are required to build M2Crypto. To fix the error command 'swig' failed with exit status 1 while installing M2Crypto, try installing it with the following command:

    env SWIG_FEATURES="-cpperraswarn -includeall -D__`uname -m`__ -I/usr/include/openssl" pip install M2Crypto

    Debian and Ubuntu systems have modified openssl libraries and mandate that a patched version of M2Crypto be installed. This means that M2Crypto needs to be installed via apt:

    apt-get install python-m2crypto

    This also means that pulling in the M2Crypto installed using apt requires using --system-site-packages when creating the virtualenv.

Note
    Installing psutil

    Python header files are required to build this module, otherwise the pip install will fail. If your distribution separates binaries and headers into separate packages, make sure that you have the headers installed. In most Linux distributions which split the headers into their own package, this can be done by installing the python-dev or python-devel package. For other platforms, the package will likely be similarly named.

Note
    Important note for those developing using RedHat variants

    For developers using a RedHat variant, be advised that the package provider for newer Redhat-based systems (yumpkg.py) relies on RedHat's python interface for yum. The variants that use this module to provide package support include the following:

•   RHEL and CentOS releases 6 and later

•   Fedora Linux releases 11 and later

•   Amazon Linux

    Developers using one of these systems should create the salt virtualenv using the --system-site-packages option to ensure that the correct modules are available.

Note
    Installing dependencies on OS X.

    You can install needed dependencies on OS X using homebrew or macports. See OS X Installation

  Running a self-contained development version

During development it is easiest to be able to run the Salt master and minion that are installed in the virtualenv you created above, and also to have all the configuration, log, and cache files contained in the virtualenv as well.

Copy the master and minion config files into your virtualenv:

mkdir -p /path/to/your/virtualenv/etc/salt
cp ./salt/conf/master /path/to/your/virtualenv/etc/salt/master
cp ./salt/conf/minion /path/to/your/virtualenv/etc/salt/minion

Edit the master config file:

1.  Uncomment and change the user: root value to your own user.

2.  Uncomment and change the root_dir: / value to point to /path/to/your/virtualenv.

3.  If you are running version 0.11.1 or older, uncomment and change the pidfile: /var/run/salt-master.pid value to point to /path/to/your/virtualenv/salt-master.pid.

4.  If you are also running a non-development version of Salt you will have to change the publish_port and ret_port values as well.

    Edit the minion config file:

1.  Repeat the edits you made in the master config for the user and root_dir values as well as any port changes.

2.  If you are running version 0.11.1 or older, uncomment and change the pidfile: /var/run/salt-minion.pid value to point to /path/to/your/virtualenv/salt-minion.pid.

3.  Uncomment and change the master: salt value to point at localhost.

4.  Uncomment and change the id: value to something descriptive like "saltdev". This isn't strictly necessary but it will serve as a reminder of which Salt installation you are working with.

Note
    Using salt-call with a Standalone Minion

    If you plan to run salt-call with this self-contained development environment in a masterless setup, you should invoke salt-call with -c /path/to/your/virtualenv/etc/salt so that salt can find the minion config file. Without the -c option, Salt finds its config files in /etc/salt.

Start the master and minion, accept the minon's key, and verify your local Salt installation is working:

cd /path/to/your/virtualenv
salt-master -c ./etc/salt -d
salt-minion -c ./etc/salt -d
salt-key -c ./etc/salt -L
salt-key -c ./etc/salt -A
salt -c ./etc/salt '*' test.ping

Running the master and minion in debug mode can be helpful when developing. To do this, add -l debug to the calls to salt-master and salt-minion. If you would like to log to the console instead of to the log file, remove the -d.

Once the minion starts, you may see an error like the following:

zmq.core.error.ZMQError: ipc path "/path/to/your/virtualenv/var/run/salt/minion/minion_event_7824dcbcfd7a8f6755939af70b96249f_pub.ipc" is longer than 107 characters (sizeof(sockaddr_un.sun_path)).

This means the the path to the socket the minion is using is too long. This is a system limitation, so the only workaround is to reduce the length of this path. This can be done in a couple different ways:

1.  Create your virtualenv in a path that is short enough.

2.  Edit the sock_dir minion config variable and reduce its length. Remember that this path is relative to the value you set in root_dir.

    NOTE: The socket path is limited to 107 characters on Solaris and Linux, and 103 characters on BSD-based systems.

Note
    File descriptor limits

    Ensure that the system open file limit is raised to at least 2047:

    # check your current limit
    ulimit -n
    # raise the limit. persists only until reboot
    # use 'limit descriptors 2047' for c-shell
    ulimit -n 2047

    To set file descriptors on OSX, refer to the OS X Installation instructions.

  Running the tests

You will need mock to run the tests:

pip install mock

If you are on Python < 2.7 then you will also need unittest2:

pip install unittest2

Finally you use setup.py to run the tests with the following command:

./setup.py test

For greater control while running the tests, please try:

./tests/runtests.py -h

  Editing and previewing the documention

You need sphinx-build command to build the docs. In Debian/Ubuntu this is provided in the python-sphinx package. You can also install this directly to your virtual environment using pip:

pip install Sphinx

Change to salt documention directory, then:

cd doc; make html

•   The docs then are built in the docs/_build/html/ folder. If you make changes and want to see the results, make html again.

•   The docs use reStructuredText for markup. See a live demo at http://rst.ninjs.org/.

•   The help information on each module or state is culled from the python code that runs for that piece. Find them in salt/modules/ or salt/states/.

•   If you are developing using Arch Linux (or any other distribution for which Python 3 is the default Python installation), then sphinx-build may be named sphinx-build2 instead. If this is the case, then you will need to run the following make command:

    make SPHINXBUILD=sphinx-build2 html

TARGETING

Targeting
    Specifying which minions should run a command or execute a state by matching against hostnames, or system information, or defined groups, or even combinations thereof.

    For example the command salt web1 apache.signal restart to restart the Apache httpd server specifies the machine web1 as the target and the command will only be run on that one minion.

    Similarly when using States, the following top file specifies that only the web1 minion should execute the contents of webserver.sls:

    base:
      'web1':
        - webserver

    There are many ways to target individual minions or groups of minions in Salt:

  Matching the minion id

minion id
    A unique identifier for a given minion. By default the minion id is the FQDN of that host but this can be overridden.

    Each minion needs a unique identifier. By default when a minion starts for the first time it chooses its FQDN as that identifier. The minion id can be overridden via the minion's id configuration setting.

Tip minion id and minion keys

    The minion id is used to generate the minion's public/private keys and if it ever changes the master must then accept the new key as though the minion was a new host.

  Globbing

The default matching that Salt utilizes is shell-style globbing around the minion id. This also works for states in the top file.

Note
    You must wrap salt calls that use globbing in single-quotes to prevent the shell from expanding the globs before Salt is invoked.

Match all minions:

salt '*' test.ping

Match all minions in the example.net domain or any of the example domains:

salt '*.example.net' test.ping
salt '*.example.*' test.ping

Match all the webN minions in the example.net domain (web1.example.net, web2.example.net … webN.example.net):

salt 'web?.example.net' test.ping

Match the web1 through web5 minions:

salt 'web[1-5]' test.ping

Match the web-x, web-y, and web-z minions:

salt 'web-[x-z]' test.ping

  Regular Expressions

Minions can be matched using Perl-compatible regular expressions (which is globbing on steroids and a ton of caffeine).

Match both web1-prod and web1-devel minions:

salt -E 'web1-(prod|devel)' test.ping

When using regular expressions in a State's top file, you must specify the matcher as the first option. The following example executes the contents of webserver.sls on the above-mentioned minions.

base:
  'web1-(prod|devel)':
  - match: pcre
  - webserver

  Lists

At the most basic level, you can specify a flat list of minion IDs:

salt -L 'web1,web2,web3' test.ping

  Grains

Salt comes with an interface to derive information about the underlying system. This is called the grains interface, because it presents salt with grains of information.

Grains
    Static bits of information that a minion collects about the system when the minion first starts.

    The grains interface is made available to Salt modules and components so that the right salt minion commands are automatically available on the right systems.

    It is important to remember that grains are bits of information loaded when the salt minion starts, so this information is static. This means that the information in grains is unchanging, therefore the nature of the data is static. So grains information are things like the running kernel, or the operating system.

    Match all CentOS minions:

    salt -G 'os:CentOS' test.ping

    Match all minions with 64-bit CPUs and return number of available cores:

    salt -G 'cpuarch:x86_64' grains.item num_cpus

  Listing Grains

Available grains can be listed by using the 'grains.ls' module:

salt '*' grains.ls

Grains data can be listed by using the 'grains.items' module:

salt '*' grains.items

  Grains in the Minion Config

Grains can also be statically assigned within the minion configuration file. Just add the option grains and pass options to it:

grains:
  roles:
    - webserver
    - memcache
  deployment: datacenter4
  cabinet: 13
  cab_u: 14-15

Then status data specific to your servers can be retrieved via Salt, or used inside of the State system for matching. It also makes targeting, in the case of the example above, simply based on specific data about your deployment.

  Writing Grains

Grains are easy to write. The grains interface is derived by executing all of the "public" functions found in the modules located in the grains package or the custom grains directory. The functions in the modules of the grains must return a Python dict, where the keys in the dict are the names of the grains and the values are the values.

Custom grains should be placed in a _grains directory located under the file_roots specified by the master config file. They will be distributed to the minions when state.highstate is run, or by executing the saltutil.sync_grains or saltutil.sync_all functions.

Before adding a grain to Salt, consider what the grain is and remember that grains need to be static data. If the data is something that is likely to change, consider using Pillar instead.

  Examples of Grains

The core module in the grains package is where the main grains are loaded by the Salt minion and provides the principal example of how to write grains:

https://github.com/saltstack/salt/blob/develop/salt/grains/core.py

  Syncing Grains

Syncing grains can be done a number of ways, they are automatically synced when state.highstate is called, or the grains can be synced and reloaded by calling the saltutil.sync_grains or saltutil.sync_all functions.

  Node groups

Node group
    A predefined group of minions declared in the master configuration file nodegroups setting as a compound target.

    Nodegroups are declared using a compound target specification. The compound target documentation can be found here:

    Compound Matchers

    For example, in the master config file nodegroups setting:

    nodegroups:
      group1: 'L@foo.domain.com,bar.domain.com,baz.domain.com or bl*.domain.com'
      group2: 'G@os:Debian and foo.domain.com'

    Specify a nodegroup via the -N option at the command-line:

    salt -N group1 test.ping

    Specify a nodegroup with - match: nodegroup in a top file:

    base:
      group1:
        - match: nodegroup
        - webserver

  Compound matchers

Compound matcher
    A combination of many target definitions that can be combined with boolean operators.

    Compound matchers allow very granular minion targeting using any of the previously discussed matchers. The default matcher is a glob, as usual. For matching via anything other than glob, preface it with the letter denoting the match type. The currently implemented "letters" are:
    Letter | Meaning | Example
    G | Grains glob match | G@os:Ubuntu
    E | PCRE Minion id match | E@web\d+\.(dev|qa|prod)\.loc
    P | Grains PCRE match | P@os:(RedHat|Fedora|CentOS)
    L | List of minions | L@minion1.example.com,minion3.domain.com or bl*.domain.com
    I | Pillar glob match | I@pdata:foobar
    S | Subnet/IP addr match | S@192.168.1.0/24 or S@192.168.1.100
    R | Range cluster match | R@%foo.bar
    D | Minion Data match | D@key:value

    Matchers can be joined using boolean and, or, and not operators.

    For example, the following command matches all minions that have a hostname that begins with "webserv" and that are running Debian or it matches any minions that have a hostname that matches the regular expression web-dc1-srv.*:

    salt -C 'webserv* and G@os:Debian or E@web-dc1-srv.*' test.ping

    That same example expressed in a top file looks like the following:

    base:
      'webserv* and G@os:Debian or E@web-dc1-srv.*':
        - match: compound
        - webserver

  Batch Size

The batch size option allows commands to be executed while maintaining that only so many hosts are executing the command at one time. This option can take a percentage or a finite number:

salt \* -b 10 test.ping
salt -G 'os:RedHat' --batch-size 25% apache.signal restart

This will only run test.ping on 10 of the targeted minions at a time and then restart apache on 25% of the minions matching os:RedHat at a time and work through them all until the task is complete. This makes jobs like rolling web server restarts behind a load balancer or doing maintenance on BSD firewalls using carp much easier with salt.

The batch system maintains a window of running minions, so, if there are a total of 150 minions targeted and the batch size is 10, then the command is sent to 10 minions, when one minion returns then the command is sent to one additional minion, so that the job is constantly running on 10 minions.

SALT TUTORIALS

  Bootstrapping Salt on Linux EC2 with Cloud-Init

Salt is a great tool for remote execution and configuration management, however you will still need to bootstrap the daemon when spinning up a new node. One option is to create and save a custom AMI, but this creates another resource to maintain and document.

A better method for Linux machines uses Canonical's CloudInit to run a bootstrap script during an EC2 Instance initialization. Cloud-init takes the user_data string passed into a new AWS instance and runs it in a manner similar to rc.local. The bootstrap script needs to:

1.  Install Salt with dependencies

2.  Point the minion to the master

    Here is a sample script:

    #!/bin/bash
    # Install saltstack
    add-apt-repository ppa:saltstack/salt -y
    apt-get update -y
    apt-get install salt-minion -y
    apt-get install salt-master -y
    apt-get upgrade -y
    # Set salt master location and start minion
    sed -i 's/#master: salt/master: [salt_master_fqdn]/' /etc/salt/minion
    salt-minion -d

    First the script adds the saltstack ppa and installs the package. Then we copy over the minion config template and tell it where to find the master. You will have to replace [salt_master_fqdn] with something that resolves to your Salt master.

  Used With Boto

Boto will accept a string for user data which can be used to pass our bootstrap script. If the script is saved to a file, you can read it into a string:

import boto
user_data = open('salt_bootstrap.sh')
conn = boto.connect_ec2(<AWS_ACCESS_ID>, <AWS_SECRET_KEY>)
reservation = conn.run_instances(image_id=<ami_id>,
                                 key_name=<key_name>,
                                 user_data=user_data.read())

  Additional Notes

Sometime in the future the ppa will include and install an upstart file. In the meantime, you can use the bootstrap to build one.

It may also be useful to set the node's role during this phase. One option would be saving the node's role to a file and then using a custom Grain to select it.

  Using cron with Salt

The Salt Minion can initiate its own highstate using the salt-call command.

$ salt-call state.highstate

This will cause the minion to check in with the master and ensure it is in the correct 'state'.

  Use cron to initiate a highstate

If you would like the Salt Minion to regularly check in with the master you can use the venerable cron to run the salt-call command.

# PATH=/bin:/sbin:/usr/bin:/usr/sbin
00 00 * * * salt-call state.highstate

The above cron entry will run a highstate every day at midnight.

Note
    Be aware that you may need to ensure the PATH for cron includes any scripts or commands that need to be executed.

  Automatic Updates / Frozen Deployments

New in version 0.10.3.d.

Salt has support for the Esky application freezing and update tool. This tool allows one to build a complete zipfile out of the salt scripts and all their dependencies - including shared objects / DLLs.

  Getting Started

To build frozen applications, you'll need a suitable build environment for each of your platforms. You should probably set up a virtualenv in order to limit the scope of Q/A.

This process does work on Windows. Follow the directions at https://github.com/saltstack/salt-windows-install for details on installing Salt in Windows. Only the 32-bit Python and dependencies have been tested, but they have been tested on 64-bit Windows.

You will need to install esky and bbfreeze from Pypi in order to enable the bdist_esky command in setup.py.

  Building and Freezing

Once you have your tools installed and the environment configured, you can then python setup.py bdist to get the eggs prepared. After that is done, run python setup.py bdist_esky to have Esky traverse the module tree and pack all the scripts up into a redistributable. There will be an appropriately versioned salt-VERSION.zip in dist/ if everything went smoothly.

  Windows

You will need to add C:\Python27\lib\site-packages\zmq to your PATH variable. This helps bbfreeze find the zmq dll so it can pack it up.

  Using the Frozen Build

Unpack the zip file in your desired install location. Scripts like salt-minion and salt-call will be in the root of the zip file. The associated libraries and bootstrapping will be in the directories at the same level. (Check the Esky documentation for more information)

To support updating your minions in the wild, put your builds on a web server that your minions can reach. salt.modules.saltutil.update() will trigger an update and (optionally) a restart of the minion service under the new version.

  Gotchas

  My Windows minion isn't responding

The process dispatch on Windows is slower than it is on *nix. You may need to add '-t 15' to your salt calls to give them plenty of time to return.

  Windows and the Visual Studio Redist

You will need to install the Visual C++ 2008 32-bit redistributable on all Windows minions. Esky has an option to pack the library into the zipfile, but OpenSSL does not seem to acknowledge the new location. If you get a no OPENSSL_Applink error on the console when trying to start your frozen minion, you have forgotten to install the redistributable.

  Mixed Linux environments and Yum

The Yum Python module doesn't appear to be available on any of the standard Python package mirrors. If you need to support RHEL/CentOS systems, you should build on that platform to support all your Linux nodes. Also remember to build your virtualenv with --system-site-packages so that the yum module is included.

  Automatic (Python) module discovery

Automatic (Python) module discovery does not work with the late-loaded scheme that Salt uses for (Salt) modules. You will need to explicitly add any misbehaving modules to the freezer_includes in Salt's setup.py. Always check the zipped application to make sure that the necessary modules were included.

  Opening the Firewall up for Salt

The Salt master communicates with the minions using an AES-encrypted ZeroMQ connection. These communications are done over ports 4505 and 4506, which need to be accessible on the master only. This document outlines suggested firewall rules for allowing these incoming connections to the master.

Note
    No firewall configuration needs to be done on Salt minions. These changes refer to the master only.

  RHEL 6 / CENTOS 6

The lokkit command packaged with some linux distributions makes opening iptables firewall ports very simple via the command line. Just be careful to not lock out access to the server by neglecting to open the ssh port.

lokkit example

lokkit -p 22:tcp -p 4505:tcp -p 4506:tcp

The system-config-firewall-tui command provides a text-based interface to modifying the firewall.

system-config-firewall-tui

system-config-firewall-tui

  iptables

Different Linux distributions store their iptables rules in different places, which makes it difficult to standardize firewall documentation. Included are some of the more common locations, but your mileage may vary.

Fedora / RHEL / CentOS

/etc/sysconfig/iptables

Arch Linux

/etc/iptables/iptables.rules

Debian

Follow these instructions: http://wiki.debian.org/iptables

Once you've found your firewall rules, you'll need to add the two lines below to allow traffic on tcp/4505 and tcp/4506:

-A INPUT -m state --state new -m tcp -p tcp --dport 4505 -j ACCEPT
-A INPUT -m state --state new -m tcp -p tcp --dport 4506 -j ACCEPT

Ubuntu

Salt installs firewall rules in /etc/ufw/applications.d/salt.ufw. Enable with:

ufw allow salt

  pf.conf

The BSD-family of operating systems uses packet filter (pf). The following example describes the additions to pf.conf needed to access the Salt master.

pass in on $int_if proto tcp from any to $int_if port 4505
pass in on $int_if proto tcp from any to $int_if port 4506

Once these additions have been made to the pf.conf the rules will need to be reloaded. This can be done using the pfctl command.

pfctl -vf /etc/pf.conf

  GitFS Backend Walkthrough

While the default location of the salt state tree is on the Salt master, in /srv/salt, the master can create a bridge to external resources for files. One of these resources is the ability for the master to directly pull files from a git repository and serve them to minions.

Note
    This walkthrough assumes basic knowledge of Salt: Walkthrough

    And a basic knowledge of file roots: File Roots

The gitfs backend hooks into any number of remote git repositories and caches the data from the repository on the master. This makes distributing a state tree to multiple masters seamless and automated.

Salt's file server also has a concept of environments, when using the gitfs backend, Salt translates git branches and tags into environments, making environment management very simple. Just merging a QA or staging branch up to a production branch can be all that is required to make those file changes available to Salt.

  Simple Configuration

To use the gitfs backend only two configuration changes are required on the master. The fileserver_backend option needs to be set with git:

fileserver_backend:
  - git

To configure what fileserver backends will be searched for requested files.

Now the gitfs system needs to be configured with a remote:

gitfs_remotes:
  - git://github.com/saltstack/salt-states.git

These changes require a restart of the master, then the git repo will be cached on the master and new requests for the salt:// protocol will send files found in the remote git repository via the master.

Note
    The master caches the files from the git server and serves them out, minions do not connect directly to the git server meaning that only requested files are delivered to minions.

  Multiple Remotes

The gitfs_remotes option can accept a list of git remotes, the remotes are then searched in order for the requested file. A simple scenario can illustrate this behavior.

Assuming that the gitfs_remotes option specifies three remotes:

gitfs_remotes:
  - git://github.com/example/first.git
  - git://github.com/example/second.git
  - git://github.com/example/third.git

Note
    This example is purposefully contrived to illustrate the behavior of the gitfs backend. This example should not be read as a recommended way to lay out files and git repos.

Assume that each repository contains some files:

first.git:
    top.sls edit/vim.sls edit/vimrc nginx/init.sls

second.git:
    edit/dev_vimrc haproxy/init.sls

third.git:
    haproxy/haproxy.conf edit/dev_vimrc

    The repositories will be searched for files by the master in the order in which they are defined in the configuration, Therefore the remote git://github.com/example/first.git will be searched first, if the requested file is found then it is served and no further searching is executed. This means that if the file salt://haproxy/init.sls is requested then it will be pulled from the git://github.com/example/second.git git repo. If salt://haproxy/haproxy.conf is requested then it will be pulled from the third repo.

  Multiple Backends

Sometimes it may make sense to use multiple backends. For instance, if sls files are stored in git, but larger files need to be stored directly on the master.

The logic used for multiple remotes is also used for multiple backends. If the fileserver_backend option contains multiple backends:

fileserver_backend:
  - roots
  - git

Then the roots backend (the default backend of files in /srv/salt) will be searched first for the requested file, then if it is not found on the master the git remotes will be searched.

  Order your minions around

Now that you have a master and at least one minion communicating with each other you can perform commands on the minion via the salt command. Salt calls are comprised of three main components:

salt '<target>' <function> [arguments]

See also

    salt manpage

  target

The target component allows you to filter which minions should run the following function. The default filter is a glob on the minion id. For example:

salt '*' test.ping
salt '*.example.org' test.ping

Targets can be based on minion system information using the Grains system:

salt -G 'os:Ubuntu' test.ping

See also

    Grains system

Targets can be filtered by regular expression:

salt -E 'virtmach[0-9]' test.ping

Targets can be explicitly specified in a list:

salt -L 'foo,bar,baz,quo' test.ping

Or Multiple target types can be combined in one command:

salt -C 'G@os:Ubuntu and webser* or E@database.*' test.ping

  function

A function is some functionality provided by a module. Salt ships with a large collection of available functions. List all available functions on your minions:

salt '*' sys.doc

Here are some examples:

Show all currently available minions:

salt '*' test.ping

Run an arbitrary shell command:

salt '*' cmd.run 'uname -a'

See also

    the full list of modules

  arguments

Space-delimited arguments to the function:

salt '*' cmd.exec_code python 'import sys; print sys.version'

Optional, keyword arguments are also supported:

salt '*' pip.install salt timeout=5 upgrade=True

They are always in the form of kwarg=argument.

  Pillar Walkthrough

Note
    This walkthrough assumes that the reader has already completed the initial Salt Stack walkthrough: Walkthrough

The pillar interface inside of Salt is one of the most important components of a Salt deployment. Pillar is the interface used to generate arbitrary data for specific minions. The data generated in pillar is made available to almost every component of Salt and is used for a number of purposes:

Highly Sensitive Data:
    Information transferred via pillar is guaranteed to only be presented to the minions that are targeted, this makes pillar the engine to use in Salt for managing security information, such as cryptographic keys and passwords.

Minion Configuration:
    Minion modules such as the execution modules, states, and returners can often be configured via data stored in pillar.

Variables:
    Variables which need to be assigned to specific minions or groups of minions can be defined in pillar and then accessed inside sls formulas and template files.

Arbitrary Data:
    Pillar can contain any basic data structure, so a list of values, or a key/value store can be defined making it easy to iterate over a group of values in sls formulas

    Pillar is therefore one of the most important systems when using Salt, this walkthrough is designed to get a simple pillar up and running in a few minutes and then to dive into the capabilities of pillar and where the data is available.

  Setting Up Pillar

The pillar is already running in Salt by default. The data in the minion's pillars can be seen via the following command: # salt '*' pillar.data

By default the contents of the master configuration file are loaded into pillar for all minions, this is to enable the master configuration file to be used for global configuration of minions.

The pillar is built in a similar fashion as the state tree, it is comprised of sls files and has a top file, just like the state tree. The pillar is stored in a different location on the Salt master than the state tree. The default location for the pillar is in /srv/pillar.

Note
    The pillar location can be configured via the pillar_roots option inside the master configuration file.

To start setting up the pillar, the /srv/pillar directory needs to be present: # mkdir /srv/pillar

Now a simple top file, following the same format as the top file used for states needs to be created:

/srv/pillar/top.sls

base:
  '*':
    - data

This top file associates the data.sls file to all minions. Now the /srv/pillar/data.sls file needs to be populated:

/srv/pillar/data.sls

info: some data

Now that the file has been saved the minions' pillars will be updated: # salt '*' pillar.data

The key info should now appear in the returned pillar data.

  More Complex Data

Pillar files are sls files, just like states, but unlike states they do not need to define formulas, the data can be arbitrary, this example for instance sets up user data with a UID:

/srv/pillar/users/init.sls

users:
  thatch: 1000
  shouse: 1001
  utahdave: 1002
  redbeard: 1003

Note
    The same directory lookups that exist in states exist in pillar, so the file users/init.sls can be referenced with users in the top file

The top file will need to updated to include this sls file:

/srv/pillar/top.sls

base:
  '*':
    - data
    - users

Now the data will be available to the minions. To use the pillar data in a state just access the pillar via Jinja:

/srv/salt/users/init.sls

{% for user, uid in pillar.get('users', {}).items() %}
{{user}}:
  user.present:
    - uid: {{uid}}
{% endfor %}

This approach allows for users to be safely defined in a pillar and then the user data is applied in an sls file.

  Paramaterizing States With Pillar

One of the most powerful abstractions in pillar is the ability to parameterize states. Instead of defining macros or functions within the state context the entire state tree can be freely parameterized relative to the minion's pillar.

This approach allows for Salt to be very flexible while staying very straightforward. It also means that simple sls formulas used in the state tree can be directly parameterized without needed to refactor the state tree.

A simple example is to set up a mapping of package names in pillar for separate Linux distributions:

/srv/pillar/pkg/init.sls

pkgs:
  {% if grains['os_family'] == 'Debian' %}
  apache: httpd
  vim: vim-enhanced
  {% elif grains['os_family'] == 'RedHat' %}
  apache: apache2
  vim: vim
  {% elif grains['os'] == 'Arch' %}
  apache: apache
  vim: vim
  {% endif %}

The new pkg sls needs to be added to the top file:

/srv/pillar/top.sls

base:
  '*':
    - data
    - users
    - pkg

Now the minions will auto map values based on respective operating systems inside of the pillar, so sls files can be safely parameterized:

/srv/salt/apache/init.sls

apache:
  pkg.installed:
    - name: {{ pillar['pkgs']['apache'] }}

Or, if no pillar is available a default can be set as well:

Note
    The function pillar.get used in this example was added to Salt in version 0.14.0

/srv/salt/apache/init.sls

apache:
  pkg.installed:
    - name: {{ salt['pillar.get']('pkgs:apache', 'httpd') }}

In the above example, if the pillar value pillar['pkgs']['apache'] is not set in the minion's pillar, then the default of 'httpd' will be used.

  Pillar Makes Simple States Grow Easily

One of the design goals of pillar is to make simple sls formulas easily grow into more flexible formulas without refactoring or complicating the states.

A simple formula:

/srv/salt/edit/vim.sls

vim:
  pkg:
    - installed
/etc/vimrc:
  file.managed:
    - source: salt://edit/vimrc
    - mode: 644
    - user: root
    - group: root
    - require:
      - pkg: vim

Can be easily transformed into a powerful, parameterized formula:

/srv/salt/edit/vim.sls

vim:
  pkg:
    - installed
    - name: {{ pillar['pkgs']['vim'] }}
/etc/vimrc:
  file.managed:
    - source: {{ pillar['vimrc'] }}
    - mode: 644
    - user: root
    - group: root
    - require:
      - pkg: vim

Where the vimrc source location can now be changed via pillar:

/srv/pillar/edit/vim.sls

{% if grain['id'].startswith('dev') %}
vimrc: salt://edit/dev_vimrc
{% elif grain['id'].startswith('qa') %}
vimrc: salt://edit/qa_vimrc
{% else %}
vimrc: salt://edit/vimrc
{% endif %}

Ensuring that the right vimrc is sent out to the correct minions.

  More On Pillar

The pillar data is generated on the Salt master and securely distributed to minions. Salt is not restricted to the pillar sls files when defining the pillar but can retrieve data from external sources. This can be useful when information about an infrastructure is stored in a separate location.

Reference information on pillar and the external pillar interface can be found in the Salt Stack documentation:

Pillar

  Preseed Minion with Accepted Key

In some situations, it is not convenient to wait for a minion to start before accepting its key on the master. For instance, you may want the minion to bootstrap itself as soon as it comes online. You may also want to to let your developers provision new development machines on the fly.

There is a general four step process to do this:

1.  Generate the keys on the master:

    root@saltmaster# salt-key --gen-keys=[key_name]

    Pick a name for the key, such as the minion's id.

2.  Add the public key to the accepted minion folder:

    root@saltmaster# cp key_name.pub /etc/salt/pki/master/minions/[minion_id]

    It is necessary that the public key file has the same name as your minion id. This is how Salt matches minions with their keys. Also note that the pki folder could be in a different location, depending on your OS or if specified in the master config file.

3.  Distribute the minion keys.

    There is no single method to get the keypair to your minion. If you are spooling up minions on EC2, you could pass them in using user_data or a cloud-init script. If you are handing them off to a team of developers for provisioning dev machines, you will need a secure file transfer.

Security Warning

    Since the minion key is already accepted on the master, distributing the private key poses a potential security risk. A malicious party will have access to your entire state tree and other sensitive data.

4.  Preseed the Minion with the keys

    You will want to place the minion keys before starting the salt-minion daemon:

    /etc/salt/pki/minion/minion.pem
    /etc/salt/pki/minion/minion.pub

    Once in place, you should be able to start salt-minion and run salt-call state.highstate or any other salt commands that require master authentication.

  Salt Masterless Quickstart

Running a masterless salt-minion lets you use salt's configuration management for a single machine. It is also useful for testing out state trees before deploying to a production setup.

The only real difference in using a standalone minion is that instead of issuing commands with salt, we use the salt-call command, like this:

salt-call --local state.highstate

  Bootstrap Salt Minion

First we need to install the salt minion. The salt-bootstrap script makes this incredibly easy for any OS with a Bourne shell. You can use it like this:

wget -O - http://bootstrap.saltstack.org | sudo sh

Or see the salt-bootstrap documentation for other one liners. Additionally, if you are using Vagrant to test out salt, the salty-vagrant tool will provision the VM for you.

  Create State Tree

Now we build an example state tree. This is where the configuration is defined. For more in depth directions, see the tutorial.

1. Create the top.sls file

# /srv/salt/top.sls
base:
  '*':
    - webserver

2. Create our webserver state tree

# /srv/salt/webserver.sls
apache:                 # ID declaration
  pkg:                  # state declaration
    - installed         # function declaration

The only thing left is to provision our minion using the highstate command. Salt-call also gives us an easy way to give us verbose output:

salt-call --local state.highstate -l debug

The --local flag tells the salt-minion to look for the state tree in the local file system. Normally the minion copies the state tree from the master and executes it from there.

That's it, good luck!

  Standalone Minion

Since the Salt minion contains such extensive functionality it can be useful to run it standalone. A standalone minion can be used to do a number of things:

•   Stand up a master server via States (Salting a Salt Master)

•   Use salt-call commands on a system without connectivity to a master

•   Masterless States, run states entirely from files local to the minion

  Telling Salt Call to Run Masterless

The salt-call command is used to run module functions locally on a minion instead of executing them from the master. Normally the salt-call command checks into the master to retrieve file server and pillar data, but when running standalone salt-call needs to be instructed to not check the master for this data. To instruct the minion to not look for a master when running salt-call the file_client configuration option needs to be set. By default the file_client is set to remote so that the minion knows that file server and pillar data are to be gathered from the master. When setting the file_client option to local the minion is configured to not gather this data from the master.

file_client: local

Now the salt-call command will not look for a master and will assume that the local system has all of the file ad pillar resources.

  Running States Masterless

The state system can be easily run without a Salt master, with all needed files local to the minion. To do this the minion configuration file needs to be set up to know how to return file_roots information like the master. The file_roots setting defaults to /srv/salt for the base environment just like on the master:

file_roots:
  base:
    - /srv/salt

Now set up the Salt State Tree, top file, and SLS modules in the same way that they would be set up on a master. Now, with the file_client option set to local and an available state tree then calls to functions in the state module will use the information in the file_roots on the minion instead of checking in with the master.

Remember that when creating a state tree on a minion there are no syntax or path changes needed, SLS modules written to be used from a master do not need to be modified in any way to work with a minion.

This makes it easy to "script" deployments with Salt states without having to set up a master, and allows for these SLS modules to be easily moved into a Salt master as the deployment grows.

Now the declared state can now be executed with:

salt-call state.highstate

Or the salt-call command can be executed with the --local flag, this makes it unnecessary to change the configuration file:

salt-call state.highstate --local

  How Do I Use Salt States?

Simplicity, Simplicity, Simplicity

Many of the most powerful and useful engineering solutions are founded on simple principles. The Salt SLS system strives to do just that. K.I.S.S.

The core of the Salt State system is the SLS, or the SaLt State file. The SLS is a representation of the state in which a system should be in, and is set up to contain this data simply. This is often called configuration management.

Note
    This is just the beginning of using states, make sure to read up on pillar next: Pillar Walkthrough

  It is All Just Data

Before delving into the particulars, it will help to understand that the SLS is just a data structure under the hood. While understanding that the SLS is just a data structure is not at all critical to understand to make use Salt States, it should help bolster the understanding of where the real power is.

SLS files are therefore, in reality, just dictionaries, lists, strings, and numbers. By using this approach Salt can be much more flexible. As someone writes more state files, it becomes clear exactly what is being written. The result is a system that is easy to understand, yet grows with the needs of the admin or developer.

In the section titled "State Data Structures" a reference exists, explaining in depth how the data is laid out.

  Default Data - YAML

By default Salt represents the SLS data in what is one of the simplest serialization formats available - YAML.

A typical SLS file will often look like this in YAML:

 apache:
   pkg:
     - installed
   service:
     - running
     - require:
       - pkg: apache

This SLS data will ensure that the package named apache is installed, and that the apache service is running. The components can be explained in a simple way.

The first line is the ID for a set of data, and it is called the ID Declaration. This ID sets the name of the thing that needs to be manipulated.

The second and fourth lines are the start of the State Declarations, so they are using the pkg and service states respectively. The pkg state manages a software package to get installed via the system's native package manager, and the service state manages a system daemon. Below the pkg and service lines are the function to run. This function defines what state the named package and service should be in. Here the package is to be installed, and the service should be running.

Finally, on line 6, is the word require. This is called a Requisite Statement, and it makes sure that the Apache service is only started after the successful installation of the apache package.

  Adding Configs and Users

When setting up a service like an Apache web server, many more components may need to be added. The Apache configuration file will most likely be managed, and a user and group may need to be set up.

 apache:
   pkg:
     - installed
   service:
     - running
     - watch:
       - pkg: apache
       - file: /etc/httpd/conf/httpd.conf
       - user: apache
   user.present:
     - uid: 87
     - gid: 87
     - home: /var/www/html
     - shell: /bin/nologin
     - require:
       - group: apache
   group.present:
     - gid: 87
     - require:
       - pkg: apache
 /etc/httpd/conf/httpd.conf:
   file.managed:
     - source: salt://apache/httpd.conf
     - user: root
     - group: root
     - mode: 644

This SLS data greatly extends the first example, and includes a config file, a user, a group and new requisite statement: watch.

Adding more states is easy, since the new user and group states are under the Apache ID, the user and group will be the Apache user and group. The require statements will make sure that the user will only be made after the group, and that the group will be made only after the Apache package is installed.

Next,the require statement under service was changed to watch, and is now watching 3 states instead of just one. The watch statement does the same thing as require, making sure that the other states run before running the state with a watch, but it adds an extra component. The watch statement will run the state's watcher function if any of the watched states changed anything. So if the package was updated, the config file changed, or the user uid modified, then the service state's watcher will be run. The service state's watcher just restarts the service, so in this case, a change in the config file will also trigger a restart of the respective service.

  Moving Beyond a Single SLS

When setting up Salt States, more than one SLS will need to be used. The above examples were just in a single SLS file, but more than one SLS file can be combined to build out a State Tree. The above example also references a file with a strange source - salt://apache/httpd.conf. That file will need to be available as well.

The SLS files are laid out in a directory on the Salt master. Files are laid out as just files. A SLS is just a file and files to download are just files.

The Apache example would be laid out in the root of the Salt file server like this:

apache/init.sls
apache/httpd.conf

So the httpd.conf is just a file in the apache directory, and is referenced directly.

But with more than a single SLS file, more components can be added to the toolkit, consider this SSH example:

ssh/init.sls:

 openssh-client:
   pkg.installed
 /etc/ssh/ssh_config:
   file.managed:
     - user: root
     - group: root
     - mode: 644
     - source: salt://ssh/ssh_config
     - require:
       - pkg: openssh-client

ssh/server.sls:

 include:
   - ssh
 openssh-server:
   pkg.installed
 sshd:
   service.running:
     - require:
       - pkg: openssh-client
       - pkg: openssh-server
       - file: /etc/ssh/banner
       - file: /etc/ssh/sshd_config
 /etc/ssh/sshd_config:
   file.managed:
     - user: root
     - group: root
     - mode: 644
     - source: salt://ssh/sshd_config
     - require:
       - pkg: openssh-server
 /etc/ssh/banner:
   file:
     - managed
     - user: root
     - group: root
     - mode: 644
     - source: salt://ssh/banner
     - require:
       - pkg: openssh-server

Note
    You may notice that we use two similar ways of denoting that a file is managed by Salt. In the /etc/ssh/sshd_config state section above, we use the file.managed state declaration whereas with the /etc/ssh/banner state section, we use the file state declaration and add a managed attribute to that state declaration. Both ways produce an identical result; the first way -- using file.managed -- is merely a shortcut.

Now our State Tree looks like this:

apache/init.sls
apache/httpd.conf
ssh/init.sls
ssh/server.sls
ssh/banner
ssh/ssh_config
ssh/sshd_config

This example now introduces the include statement. The include statement includes another SLS file so that components found in it can be required, watched or as will soon be demonstrated - extended.

The include statement allows for states to be cross linked. When an SLS has an include statement it is literally extended to include the contents of the included SLS files.

  Extending Included SLS Data

Sometimes SLS data needs to be extended. Perhaps the apache service needs to watch additional resources, or under certain circumstances a different file needs to be placed.

These examples will add more watchers to apache and change the ssh banner.

ssh/custom-server.sls:

 include:
   - ssh.server
 extend:
   /etc/ssh/banner:
     file:
       - source: salt://ssh/custom-banner

python/mod_python.sls:

 include:
   - apache
 extend:
   apache:
     service:
       - watch:
         - pkg: mod_python
 mod_python:
   pkg.installed

The custom-server.sls file uses the extend statement to overwrite where the banner is being downloaded from, and therefore changing what file is being used to configure the banner.

In the new mod_python SLS the mod_python package is added, but more importantly the apache service was extended to also watch the mod_python package.

Using extend with require or watch

    The extend statement works differently for require or watch. It appends to, rather than replacing the requisite component.

  Understanding the Render System

Since the SLS data is just plain old data, it does not need to be represented with YAML. Salt defaults to YAML because it is very straightforward and easy to learn and use. But the SLS files can be rendered from almost any imaginable medium, so long as a renderer module is provided.

The default rendering system is the yaml_jinja renderer. The yaml_jinja renderer will first pass the template through the Jinja2 templating system, and then through the YAML parser. The benefit here is that full programming constructs are available when creating SLS files.

Other renderers available are yaml_mako and yaml_wempy which each use the Mako or Wempy templating system respectively rather than the jinja templating system, and more notably, the pure Python or py and pydsl renderers. The py renderer allows for SLS files to be written in pure Python, allowing for the utmost level of flexibility and power when preparing SLS data; while the pydsl renderer provides a flexible, domain-specific language for authoring SLS data in Python.

  Getting to Know the Default - yaml_jinja

The default renderer - yaml_jinja, allows for the use of the jinja templating system. A guide to the Jinja templating system can be found here: http://jinja.pocoo.org/docs

When working with renderers a few very useful bits of data are passed in. In the case of templating engine based renderers, three critical components are available, salt, grains, and pillar. The salt object allows for any Salt function to be called from within the template, and grains allows for the Grains to be accessed from within the template. A few examples:

apache/init.sls:

 apache:
   pkg.installed:
     {% if grains['os'] == 'RedHat'%}
     - name: httpd
     {% endif %}
   service.running:
     {% if grains['os'] == 'RedHat'%}
     - name: httpd
     {% endif %}
     - watch:
       - pkg: apache
       - file: /etc/httpd/conf/httpd.conf
       - user: apache
   user.present:
     - uid: 87
     - gid: 87
     - home: /var/www/html
     - shell: /bin/nologin
     - require:
       - group: apache
   group.present:
     - gid: 87
     - require:
       - pkg: apache
 /etc/httpd/conf/httpd.conf:
   file.managed:
     - source: salt://apache/httpd.conf
     - user: root
     - group: root
     - mode: 644

This example is simple. If the os grain states that the operating system is Red Hat, then the name of the Apache package and service needs to be httpd.

A more aggressive way to use Jinja can be found here, in a module to set up a MooseFS distributed filesystem chunkserver:

moosefs/chunk.sls:

 include:
   - moosefs
 {% for mnt in salt['cmd.run']('ls /dev/data/moose*').split() %}
 /mnt/moose{{ mnt[-1] }}:
   mount.mounted:
     - device: {{ mnt }}
     - fstype: xfs
     - mkmnt: True
   file.directory:
     - user: mfs
     - group: mfs
     - require:
       - user: mfs
       - group: mfs
 {% endfor %}
 '/etc/mfshdd.cfg':
   file.managed:
     - source: salt://moosefs/mfshdd.cfg
     - user: root
     - group: root
     - mode: 644
     - template: jinja
     - require:
       - pkg: mfs-chunkserver
 '/etc/mfschunkserver.cfg':
   file.managed:
     - source: salt://moosefs/mfschunkserver.cfg
     - user: root
     - group: root
     - mode: 644
     - template: jinja
     - require:
       - pkg: mfs-chunkserver
 mfs-chunkserver:
   pkg:
     - installed
 mfschunkserver:
   service:
     - running
     - require:
 {% for mnt in salt['cmd.run']('ls /dev/data/moose*') %}
       - mount: /mnt/moose{{ mnt[-1] }}
       - file: /mnt/moose{{ mnt[-1] }}
 {% endfor %}
       - file: /etc/mfschunkserver.cfg
       - file: /etc/mfshdd.cfg
       - file: /var/lib/mfs

This example shows much more of the available power provided by Jinja. Multiple for loops are used to dynamically detect available hard drives and set them up to be mounted, and the salt object is used multiple times to call shell commands to gather data.

  Introducing the Python and the PyDSL Renderers

Sometimes the chosen default renderer might not have enough logical power to accomplish the needed task. When this happens, the Python renderer can be used. Normally a YAML renderer should be used for the majority of SLS files, but a SLS file set to use another renderer can be easily added to the tree.

This example shows a very basic Python SLS file:

python/django.sls:

 #!py
 def run():
     '''
     Install the django package
     '''
     return {'include': ['python'],
             'django': {'pkg': ['installed']}}

This is a very simple example, the first line has a SLS shebang line that tells Salt to not use the default renderer, but to use the py renderer. Then the run function is defined, the return value from the run function must be a Salt friendly data structure, or better known as a Salt HighState data structure.

Alternatively, using the pydsl renderer, the above example can be written more succinctly as:

python/django.sls:

 #!pydsl
 include('python', delayed=True)
 state('django').pkg.installed()

This Python examples would look like this if they were written in YAML:

 include:
   - python
 django:
   pkg.installed

This clearly illustrates, that not only is using the YAML renderer a wise decision as the default, but that unbridled power can be obtained where needed by using a pure Python SLS.

  Running and debugging salt states.

Once the rules in an SLS are ready, they need to be tested to ensure they work properly. To invoke the rules, simply execute salt '*' state.highstate on the command line. If you get back just the hostnames with a : after, but no return, chances are there is a problem with the one or more of the sls files. Use the salt-call command: salt-call state.highstate -l debug and examine the output for errors. This should help troubleshoot the issue. The minions can also be started in the foreground in debug mode. Start the minion in debug mode with: salt-minion -l debug.

  States tutorial, part 1

The purpose of this tutorial is to demonstrate how quickly you can configure a system to be managed by Salt States. For detailed information about the state system please refer to the full states reference.

This tutorial will walk you through using Salt to configure a minion to run the Apache HTTP server and to ensure the server is running.

Before continuing make sure you have a working Salt installation by following the installation and the configuration instructions.

Stuck?

    There are many ways to get help from the Salt community including our mailing list and our IRC channel #salt.

  Setting up the Salt State Tree

States are stored in text files on the master and transferred to the minions on demand via the master's File Server. The collection of state files make up the State Tree.

To start using a central state system in Salt you must first set up the Salt File Server. Edit your master config file (file_roots) and uncomment the following lines:

file_roots:
  base:
    - /srv/salt

Note
    If you are deploying on FreeBSD via ports, the file_roots path defaults to /usr/local/etc/salt/states.

Restart the Salt master in order to pick up this change:

% pkill salt-master
% salt-master -d

  Preparing the Top File

On the master in the directory you uncommented in the previous step (/srv/salt by default), create a new file called top.sls and add the following:

base:
  '*':
    - webserver

The top file is separated into environments (discussed later). The default environment is base. Under the base environment a collection of minion matches is defined; for now simply specify all hosts (*).

Targeting minions

    The expressions can use any of the targeting mechanisms used by Salt — minions can be matched by glob, PCRE regular expression, or by grains. For example:

    base:
      'os:Fedora':
        - match: grain
        - webserver

  Create an sls module

In the same directory as your top file, create an empty file, called an SLS module, named webserver.sls. Type the following and save the file:

apache:                 # ID declaration
  pkg:                  # state declaration
    - installed         # function declaration

The first line, called the ID declaration, is an arbitrary identifier. In this case it defines the name of the package to be installed. NOTE: the package name for the Apache httpd web server may differ on your OS or distro — for example, on Fedora it is httpd but on Debian/Ubuntu it is apache2.

The second line, called the state declaration, defines which of the Salt States we are using. In this example, we are using the pkg state to ensure that a given package is installed.

The third line, called the function declaration, defines which function in the pkg state module to call.

Renderers

    States sls files can be written in many formats. Salt requires only a simple data structure and is not concerned with how that data structure is built. Templating languages and DSLs are a dime-a-dozen and everyone has a favorite.

    Building the expected data structure is the job of Salt renderers and they are dead-simple to write.

    In this tutorial we will be using YAML in Jinja2 templates, which is the default format. You can change the default by changing renderer in the master configuration file.

  Install the package

Next, let's run the state we created. Open a terminal on the master and run:

% salt '*' state.highstate

Our master is instructing all targeted minions to run state.highstate. When a minion executes a highstate call it will download the top file and attempt to match the expressions. When it does match an expression the modules listed for it will be downloaded, compiled, and executed.

Once completed, the minion will report back with a summary of all actions taken and all changes made.

Troubleshooting Salt

    In case you don't see the expected output, the following tips can help you narrow down the problem.

Turn up logging
    Salt can be quite chatty when you change the logging setting to debug:

    salt-minion -l debug

Run the minion in the foreground
    By not starting the minion in daemon mode (-d) you can view any output from the minion as it works:

    salt-minion &

    Increase the default timeout value when running salt. For example, to change the default timeout to 60 seconds:

    salt -t 60

    For best results, combine all three:

    salt-minion -l debug &          # On the minion
    salt '*' state.highstate -t 60  # On the master

  Next steps

This tutorial focused on getting a simple Salt States configuration working. Part 2 will build on this example to cover more advanced sls syntax and will explore more of the states that ship with Salt.

  States tutorial, part 2

Note
    This tutorial builds on the topic covered in part 1. It is recommended that you begin there.

In the last part of the Salt States tutorial we covered the basics of installing a package. We will now modify our webserver.sls file to have requirements, and use even more Salt States.

  Call multiple States

You can specify multiple state declarations under an ID declaration. For example, a quick modification to our webserver.sls to also start Apache if it is not running:

Try stopping Apache before running state.highstate once again and observe the output.

  Expand the SLS module

As you have seen, SLS modules are appended with the file extension .sls and are referenced by name starting at the root of the state tree. An SLS module can be also defined as a directory. Demonstrate that now by creating a directory named webserver and moving and renaming webserver.sls to webserver/init.sls. Your state directory should now resemble:

|- top.sls
`- webserver/
   `- init.sls

Organizing SLS modules

    You can place additional .sls files in a state file directory. This affords much cleaner organization of your state tree on the filesystem. For example, if we created a webserver/django.sls file that module would be referenced as webserver.django.

    In addition, States provide powerful includes and extending functionality which we will cover in Part 3.

  Require other states

We now have a working installation of Apache so let's add an HTML file to customize our website. It isn't exactly useful to have a website without a webserver so we don't want Salt to install our HTML file until Apache is installed and running. Include the following at the bottom of your webserver/init.sls file:

line 7 is the ID declaration. In this example it is the location we want to install our custom HTML file. (Note: the default location that Apache serves may differ from the above on your OS or distro. /srv/www could also be a likely place to look.)

Line 8 the state declaration. This example uses the Salt file state.

Line 9 is the function declaration. The managed function will download a file from the master and install it in the location specified.

Line 10 is a function arg declaration which, in this example, passes the source argument to the managed function.

Line 11 is a requisite declaration.

Line 12 is a requisite reference which refers to a state and an ID. In this example, it is referring to the ID declaration from our example in part 1. This declaration tells Salt not to install the HTML file until Apache is installed.

Next, create the index.html file and save it in the webserver directory:

<html>
    <head><title>Salt rocks</title></head>
    <body>
        <h1>This file brought to you by Salt</h1>
    </body>
</html>

Last, call state.highstate again and the minion will fetch and execute the highstate as well as our HTML file from the master using Salt's File Server:

salt '*' state.highstate

Verify that Apache is now serving your custom HTML.

require vs. watch

    There are two requisite declarations, “require” and “watch”. Not every state supports “watch”. The service state does support “watch” and will restart a service based on the watch condition.

    For example, if you use Salt to install an Apache virtual host configuration file and want to restart Apache whenever that file is changed you could modify our Apache example from earlier as follows:

    If the pkg and service names differ on your OS or distro of choice you can specify each one separately using a name declaration which explained in Part 3.

  Next steps

In part 3 we will discuss how to use includes, extends and templating to make a more complete State Tree configuration.

  States tutorial, part 3

Note
    This tutorial builds on the topic covered in part1 and part 2. It is recommended that you begin there.

This part of the tutorial will cover more advanced templating and configuration techniques for sls files.

  Templating SLS modules

SLS modules may require programming logic or inline execution. This is accomplished with module templating. The default module templating system used is Jinja2 and may be configured by changing the renderer value in the master config.

All states are passed through a templating system when they are initially read. To make use of the templating system, simply add some templating markup. An example of an sls module with templating markup may look like this:

{% for usr in 'moe','larry','curly' %}
{{ usr }}:
  user.present
{% endfor %}

This templated sls file once generated will look like this:

moe:
  user.present
larry:
  user.present
curly:
  user.present

  Using Grains in SLS modules

Often times a state will need to behave differently on different systems. Salt grains objects are made available in the template context. The grains can be used from within sls modules:

apache:
  pkg.installed:
    {% if grains['os'] == 'RedHat' %}
    - name: httpd
    {% elif grains['os'] == 'Ubuntu' %}
    - name: apache2
    {% endif %}

  Calling Salt modules from templates

All of the Salt modules loaded by the minion are available within the templating system. This allows data to be gathered in real time on the target system. It also allows for shell commands to be run easily from within the sls modules.

The Salt module functions are also made available in the template context as salt:

{% for usr in 'moe','larry','curly' %}
{{ usr }}:
  group:
    - present
  user:
    - present
    - gid: {{ salt['file.group_to_gid'](usr) }}
    - require:
      - group: {{ usr }}
{% endfor %}

Below is an example that uses the network.hwaddr function to retrieve the MAC address for eth0:

salt['network.hwaddr']('eth0')

  Advanced SLS module syntax

Lastly, we will cover some incredibly useful techniques for more complex State trees.

  Include declaration

A previous example showed how to spread a Salt tree across several files. Similarly, requisite references span multiple files by using an include declaration. For example:

python/python-libs.sls:

python-dateutil:
  pkg.installed

python/django.sls:

include:
  - python-libs
django:
  pkg.installed:
    - require:
      - pkg: python-dateutil

  Extend declaration

You can modify previous declarations by using an extend declaration. For example the following modifies the Apache tree to also restart Apache when the vhosts file is changed:

apache/apache.sls:

apache:
  pkg.installed

apache/mywebsite.sls:

include:
  - apache.apache
extend:
  apache:
    service:
      - running
      - watch:
        - file: /etc/httpd/extra/httpd-vhosts.conf
/etc/httpd/extra/httpd-vhosts.conf:
  file.managed:
    - source: salt://apache/httpd-vhosts.conf

Using extend with require or watch

    The extend statement works differently for require or watch. It appends to, rather than replacing the requisite component.

  Name declaration

You can override the ID declaration by using a name declaration. For example, the previous example is a bit more maintainable if rewritten as follows:

apache/mywebsite.sls:

  Names declaration

Even more powerful is using a names declaration to override the ID declaration for multiple states at once. This often can remove the need for looping in a template. For example, the first example in this tutorial can be rewritten without the loop:

stooges:
  user.present:
    - names:
      - moe
      - larry
      - curly

  Continue learning

The best way to continue learning about Salt States is to read through the reference documentation and to look through examples of existing state trees.

  Salt Stack Walkthrough

  Welcome!

Welcome to Salt Stack! I am excited that you are interested in Salt and starting down the path to better infrastructure management. I developed (and am continuing to develop) Salt with the goal of making the best software available to manage computers of almost any kind. I hope you enjoy working with Salt and that the software can solve your real world needs!

•   Thomas S Hatch

•   Salt creator and chief developer

•   CTO of Salt Stack, Inc.

Note
    This is the first of a series of walkthroughs and serves as the best entry point for people new to Salt, after this be sure to read up on pillar and more on states: Starting States

    Pillar Walkthrough

  Getting Started

  What is Salt?

Salt is a different approach to infrastructure management, it is founded on the idea that high speed communication with large numbers of systems can open up new capabilities. This approach makes Salt a powerful multitasking system that can solve many specific problems in an infrastructure. The backbone of Salt is the remote execution engine, which creates a high speed, secure, bi-directional communication net for groups of systems. On top of this communication system Salt provides an extremely fast, flexible, easy to use configuration management system called Salt States.

This unique approach to management makes for a transparent control system that is not only amazingly easy to set up and use, but also capable of solving very complex problems in infrastructures, as will be explored in this walk through.

Salt is being used today by some of the largest infrastructures in the world and has proven an ability to scale to astounding proportions without modification. With the proven ability to scale out well beyond many tens of thousands of servers, Salt has also proven to be an excellent choice for small deployments as well, lowering compute and management overhead for infrastructures as small as just a few systems.

  Installing Salt

Salt Stack has been made to be very easy to install and get started. Setting up Salt should be as easy as installing Salt via distribution packages on Linux or via the Windows installer. The installation documents cover specific platform installation in depth:

Installation

  Starting Salt

Salt functions on a master/minion topology. A master server serves as a central control bus for the clients (called minions), and the minions connect back to the master.

  Setting Up the Salt Master

Turning on the Salt Master is easy, just turn it on! The default configuration is suitable for the vast majority of installations. The Salt master can be controlled by the local Linux/Unix service manager:

On Systemd based platforms (OpenSuse, Fedora): # systemctl start salt-master

On Upstart based systems (Ubuntu, older Fedora/RHEL): # service salt-master start

On SysV Init systems (Debian, Gentoo etc.): # /etc/init.d/salt-master start

Or the master can be started directly on the command line: # salt-master -d

The Salt Master can also be started in the foreground in debug mode, this greatly increases the command output: # salt-master -l debug

The Salt Master needs to bind to 2 TCP network ports on the system, these ports are 4505 and 4506. For more in depth information on fire walling these ports the firewall tutorial is available: Firewalling the Salt Master

  Setting up a Salt Minion

Note
    The Salt Minion can operate with or without a Salt Master. This walkthrough assumes that the minion will be connected to the master, for information on how to run a master-less minion please see the masterless quickstart guide: Masterless Minon Quickstart

The Salt Minion only needs to be aware of one piece of information to run, the network location of the master. By default the minion will look for the DNS name salt for the master, making the easiest approach to set internal DNS to resolve the name salt back to the Salt Master IP. Otherwise the minion configuration file will need to be edited, edit the configuration option master to point to the DNS name or the IP of the Salt Master:

Note
    The default location of the configuration files is /etc/salt, most platforms adhere to this convention, but platforms such as FreeBSD and Microsoft Windows place this file in different locations.

/etc/salt/minion:

master: saltmaster.example.com

Now that the master can be found start up the minion in the same way as the master, with the platform init system, or via the command line directly:

As a daemon: # salt-minion -d

In the foreground in debug mode: # salt-minion -l debug

Now that the minion is started it will generate cryptographic keys and attempt to connect to the master. The next step is to venture back to the master server and accept the new minion's public key.

  Using Salt Key

Salt authenticates minions using public key encryption and authentication. For a minion to start accepting commands from the master the minion keys need to be accepted. The salt-key command is used manage all of the keys on the master. To list the keys that are on the master run a salt-key list command: # salt-key -L

The keys that have been rejected, accepted and pending acceptance are listed. The easiest way to accept the minion key is to just accept all pending keys: # salt-key -A

Note
    Keys should be verified!! The secure thing to do is to run salt-key -P to verify that the keys on the master match the generated keys on the minions.

  Sending the First Commands

Now that the minion is connected to the master and authenticated, the master can start to command the minion. Salt commands allow for a vast set of functions to be executed and for specific minions and groups of minions to be targeted for execution. This makes the salt command very powerful, but the command is also very usable, and easy to understand.

The salt command is comprised of command options, target specification, the function to execute, and arguments to the function. A simple command to start with looks like this: # salt '*' test.ping

The * is the target, which specifies all minions, and test.ping tells the minion to run the test.ping function. This salt command will tell all of the minions to execute the test.ping in parallel and return the result.

Note
    All of the minions register themselves with a unique minion id, these ids default to the minion hostname, but can be explicitly defined in the minion config as well.

  Getting to Know the Functions

Salt comes with a vast library of functions available for execution, and Salt functions are self documenting. To see what functions are available on the minions execute the sys.doc function: # salt '*' sys.doc

This will display a very large list of available functions and documentation on them, this documentation is also available online: Full List of Execution Modules

These functions cover everything from shelling out to package management to manipulating database servers. These functions comprise a powerful system management API which is the backbone to Salt configuration management and many other aspects of Salt.

Note
    Salt comes with many plugin systems, the functions that are available via the salt command are called Execution Modules.

  Some Functions to Know

Some functions to be familiar with are around basic system management. Functions to shell out on minions such as cmd.run and cmd.run_all: # salt '*' cmd.run 'ls -l /etc'

The pkg functions will automatically map local system package managers to the same salt functions. This means that pkg.install will wrap to installing packages via yum on Red Hat based systems and apt on Debian systems etc. # salt '*' pkg.install vim

  Grains

Salt uses a system called Grains to build up static data about minions. This data includes information about the operating system that is running, CPU architecture and many more. The grains system is used throughout Salt to deliver platform data to many components and to users.

Grains can also be statically set, this makes it easy to assign values to minions for grouping and managing. A common practice is to assign grains to minions to specify what the role or roles a minion might be. These static grains can be set in the minion configuration file or via the grains.set function.

  Targetting

Salt allows for minions to be targeted based on a wide range of criteria. The default targeting system uses globular expressions to match minions, hence if there are minions named larry1, larry2, curly1 and curly2, a glob of larry* will match larry1 and larry2, and a glob of *1 will match larry1 and curly1.

Many other targeting systems can be used other than globs, these systems include:

Regular Expressions
    Target using PCRE compliant regular expressions: Targeting with Regular Expressions

Grains
    Target based on grains data: Targeting with Grains

Pillar
    Target based on pillar data: Targeting with Pillar

IP  Target based on IP addr/subnet/range: Targeting with ipcidr

Compound
    Create logic to target based on multiple targets: Targeting with Compound

Nodegroup
    Target with nodegroups: Targeting with Nodegroup

    The concepts of targets are used on the command line with salt, but also function in many other areas as well, including the state system and the systems used for ACLs and user permission restrictions.

  Salt States

Now that the basics are covered the time has come to evaluate States. Salt States, or the State System is the component of Salt made for configuration management. The State system is a fully functional configuration management system which has been designed to be exceptionally powerful while still being simple to use, fast, lightweight, deterministic and with salty levels of flexibility.

The state system is already available with a basic salt setup, no additional configuration is required, states can be set up immediately.

Note
    Before diving into the state system, a brief overview of how states are constructed will make many of the concepts clearer. Salt states are based on data modeling, and build on a low level data structure that is used to execute each state function. Then more logical layers are built on top of each other. The high layers of the state system which this tutorial will cover consists of everything that needs to be known to use states, the two high layers covered here are the sls layer and the highest layer highstate.

    Again, knowing that there are many layers of data management will help with understanding states, but they never need to be used. Just as understanding how a compiler functions when learning a programming language, understanding what is going on under the hood of a configuration management system will also prove to be a valuable asset.

  The First SLS Formula

The state system is built on sls formulas, these formulas are built out in files on Salt's file server. To make a very basic sls formula open up a file under /srv/salt named vim.sls and get vim installed:

/srv/salt/vim.sls

vim:
  pkg.installed

Now install vim on the minions by calling the sls directly: # salt '*' state.sls vim

This command will invoke the state system and run the named sls which was just created "vim".

Now to beef up the vim sls formula a vimrc can be added:

/srv/salt/vim.sls

vim:
  pkg.installed
/etc/vimrc:
  file.managed:
    - source: salt://vimrc
    - mode: 644
    - user: root
    - group: root

Now the desired vimrc needs to be copied into the Salt file server to /srv/salt/vimrc, in Salt everything is a file, so no path redirection needs to be accounted for. The vimrc file is placed right next to the vim.sls file. The same command as above can be executed to all the vim sls formula and now include managing the file.

Note
    Salt does not need to be restarted/reloaded or have the master manipulated in any way when changing sls formulas, they are instantly available.

  Adding Some Depth

Obviously maintaining sls formulas right in the root of the file server will not scale out to reasonably sized deployments. This is why more depth is required. Start by making an nginx formula a better way, make a nginx subdirectory and add an init.sls file:

/srv/salt/nginx/init.sls

nginx:
  pkg:
    - installed
  service:
    - running
    - require:
      - pkg: nginx

A few things are introduced in this sls formula, first is the service statement which ensures that the nginx service is running, but the nginx service can't be started unless the package is installed, hence the require. The require statement makes sure that the required component is executed before and that it results in success.

Note
    The require option belongs to a family of options called requisites. Requisites are a powerful component of Salt States, for more information on how requisites work and what is available see: Requisites Also evaluation ordering is available in Salt as well: Ordering States

Now this new sls formula has a special name, init.sls, when a sls formula is named init.sls it inherits the name of the directory path that contains it, so this formula can be referenced via the following command: # salt '*' state.sls nginx

Now that subdirectories can be used the vim.sls formula can be cleaned up, but to make things more flexible (and to illustrate another point of course), move the vim.sls and vimrc into a new subdirectory called edit and change the vim.sls file to reflect the change:

/srv/salt/edit/vim.sls

vim:
  pkg.installed
/etc/vimrc:
  file.managed:
    - source: salt://edit/vimrc
    - mode: 644
    - user: root
    - group: root

The only change in the file is fixing the source path for the vimrc file. Now the formula is referenced as edit.vim because it resides in the edit subdirectory. Now the edit subdirectory can contain formulas for emacs, nano, joe or any other editor that may need to be deployed.

    This still is only scratching the surface, many components such as the reactor and event systems, extending Salt, modular components and more are not covered here. For an overview of all Salt features and documentation look at the table of contents: Table Of Contents

ACCESS CONTROL SYSTEM

New in version 0.10.4.

Salt maintains a standard system used to open granular control to non administrative users to execute Salt commands. The access control system has been applied to all systems used to configure access to non administrative control interfaces in Salt.These interfaces include, the peer system, the external auth system and the client acl system.

The access control system mandated a standard configuration syntax used in all of the three aforementioned systems. While this adds functionality to the configuration in 0.10.4, it does not negate the old configuration.

Now specific functions can be opened up to specific minions from specific users in the case of external auth and client ACLs, and for specific minions in the case of the peer system.

The access controls are manifested using matchers in these configurations:

client_acl:
  fred:
    - web\*:
      - pkg.list_pkgs
      - test.*
      - apache.*

In the above example, fred is able to send commands only to minions which match the specified glob target. This can be expanded to include other functions for other minions based on standard targets.

external_auth:
  pam:
    dave:
      - test.ping
      - mongo\*:
        - network.*
      - log\*:
        - network.*
        - pkg.*
      - 'G@os:RedHat':
        - kmod.*
    steve:
      - .*

The above allows for all minions to be hit by test.ping by dave, and adds a few functions that dave can execute on other minions. It also allows steve unrestricted access to salt commands.

EXTERNAL AUTHENTICATION SYSTEM

Salt 0.10.4 comes with a fantastic new way to open up running Salt commands to users. This system allows for Salt itself to pass through authentication to any authentication system (The Unix PAM system was the first) to determine if a user has permission to execute a Salt command.

The external authentication system allows for specific users to be granted access to execute specific functions on specific minions. Access is configured in the master configuration file, and uses the new access control system:

external_auth:
  pam:
    thatch:
      - 'web*':
        - test.*
        - network.*
    steve:
      - .*

So, the above allows the user thatch to execute functions in the test and network modules on the minions that match the web* target. User steve is given unrestricted access to minion commands.

The external authentication system can then be used from the command line by any user on the same system as the master with the -a option:

$ salt -a pam web\* test.ping

The system will ask the user for the credentials required by the authentication system and then publish the command.

  Tokens

With external authentication alone the authentication credentials will be required with every call to Salt. This can be alleviated with Salt tokens.

The tokens are short term authorizations and can be easily created by just adding a -T option when authenticating:

$ salt -T -a pam web\* test.ping

Now a token will be created that has a expiration of, by default, 12 hours. This token is stored in a file named .salt_token in the active user's home directory. Once the token is created, it is sent with all subsequent communications. The user authentication does not need to be entered again until the token expires. The token expiration time can be set in the Salt master config file.

PILLAR OF SALT

Pillar is an interface for Salt designed to offer global values that can be distributed to all minions. Pillar data is managed in a similar way to the Salt State Tree.

Pillar was added to Salt in version 0.9.8

Note
    Storing sensitive data

    Unlike state tree, pillar data is only available for the targeted minion specified by the matcher type. This makes it useful for storing sensitive data specific to a particular minion.

  Declaring the Master Pillar

The Salt Master server maintains a pillar_roots setup that matches the structure of the file_roots used in the Salt file server. Like the Salt file server the pillar_roots option in the master config is based on environments mapping to directories. The pillar data is then mapped to minions based on matchers in a top file which is laid out in the same way as the state top file. Salt pillars can use the same matcher types as the standard top file.

The configuration for the pillar_roots in the master config is identical in behavior and function as the file_roots configuration:

pillar_roots:
  base:
    - /srv/pillar

This example configuration declares that the base environment will be located in the /srv/pillar directory. The top file used matches the name of the top file used for States, and has the same structure:

/srv/pillar/top.sls

base:
  '*':
    - packages

This further example shows how to use other standard top matching types (grain matching is used in this example) to deliver specific salt pillar data to minions with different 'os' grains:

dev:
  'os:Debian':
    - match: grain
    - servers

/srv/pillar/packages.sls

{% if grains['os'] == 'RedHat' %}
apache: httpd
git: git
{% elif grains['os'] == 'Debian' %}
apache: apache2
git: git-core
{% endif %}

Now this data can be used from within modules, renderers, State SLS files, and more via the shared pillar dict:

apache:
  pkg:
    - installed
    - name: {{ pillar['apache'] }}

git:
  pkg:
    - installed
    - name: {{ pillar['git'] }}

  Viewing Minion Pillar

Once the pillar is set up the data can be viewed on the minion via the pillar module, the pillar module comes with two functions, pillar.data and pillar.raw. pillar.data will return a freshly reloaded pillar and pillar.raw wil return the current pillar without a refresh:

# salt '*' pillar.data

  Footnotes

[1] Note that you cannot just list key/value-information in top.sls.

  Refreshing Pillar Data

When pillar data is changed on the master the minions need to refresh the data locally. This is done with the saltutil.refresh_pillar function.

salt '*' saltutil.refresh_pillar

This function triggers the minion to refresh the pillar and will always return True

  Targeting with Pillar

Pillar data can be used when targeting minions. This allows for ultimate control and flexibility when targeting minions.

salt -I 'somekey:specialvalue' test.ping

MASTER TOPS SYSTEM

In 0.10.4 the external_nodes system was upgraded to allow for modular subsystems to be used to generate the top file data for a highstate run on the master.

The old external_nodes option still works, but will be removed in the future in favor of the new master_tops option which uses the modular system instead. The master tops system contains a number of subsystems that are loaded via the Salt loader interfaces like modules, states, returners, runners, etc.

Using the new master_tops option is simple:

master_tops:
  ext_nodes: cobbler-external-nodes

JOB MANAGEMENT

New in version 0.9.7.

Since Salt executes jobs running on many systems, Salt needs to be able to manage jobs running on many systems. As of Salt 0.9.7, the capability was added for more advanced job management.

  The Minion proc System

The Salt Minions now maintain a proc directory in the Salt cachedir, the proc directory maintains files named after the executed job ID. These files contain the information about the current running jobs on the minion and allow for jobs to be looked up. This is located in the proc directory under the cachedir, with a default configuration it is under /var/cache/salt/proc.

  Functions in the saltutil Module

Salt 0.9.7 introduced a few new functions to the saltutil module for managing jobs. These functions are:

1.  running Returns the data of all running jobs that are found in the proc directory.

2.  find_job Returns specific data about a certain job based on job id.

3.  signal_job Allows for a given jid to be sent a signal.

4.  term_job Sends a termination signal (SIGTERM, 15) to the process controlling the specified job.

5.  kill_job Sends a kill signal (SIGKILL, 9) to the process controlling the specified job.

    These functions make up the core of the back end used to manage jobs at the minion level.

  The jobs Runner

A convenience runner front end and reporting system has been added as well. The jobs runner contains functions to make viewing data easier and cleaner.

The jobs runner contains a number of functions...

  active

The active function runs saltutil.running on all minions and formats the return data about all running jobs in a much more usable and compact format. The active function will also compare jobs that have returned and jobs that are still running, making it easier to see what systems have completed a job and what systems are still being waited on.

# salt-run jobs.active

  lookup_jid

When jobs are executed the return data is sent back to the master and cached. By default is is cached for 24 hours, but this can be configured via the keep_jobs option in the master configuration. Using the lookup_jid runner will display the same return data that the initial job invocation with the salt command would display.

# salt-run jobs.lookup_jid <job id number>

  list_jobs

Before finding a historic job, it may be required to find the job id. list_jobs will parse the cached execution data and display all of the job data for jobs that have already, or partially returned.

# salt-run jobs.list_jobs

SALT SCHEDULING

In Salt versions greater than 0.12.0, the scheduling system allows incremental executions on minions or the master. The schedule system exposes the execution of any execution function on minions or any runner on the master.

To set up the scheduler on the master add the schedule option to the master config file.

To set up the scheduler on the minion add the schedule option to the minion config file or to the minion's pillar.

The schedule option defines jobs which execute at certain intervals. To set up a highstate to run on a minion every 60 minutes set this in the minion config or pillar:

schedule:
  highstate:
    function: state.highstate
    minutes: 60

Time intervals can be specified as seconds, minutes, hours, or days. Runner executions can also be specified on the master within the master configuration file:

schedule:
  overstate:
    function: state.over
    seconds: 35
    minutes: 30
    hours: 3

The above configuration will execute the state.over runner every 3 hours, 30 minutes and 35 seconds, or every 12,635 seconds.

The scheduler is also useful for tasks like gathering monitoring data about a minion, this schedule option will gather status data and send it to a mysql returner database:

schedule:
  uptime:
    function: status.uptime
    seconds: 60
    returner: mysql
  meminfo:
    function: status.meminfo
    minutes: 5
    returner: mysql

Since specifying the returner repeatedly can be tiresome, the schedule_returner option is available to specify one or a list of global returners to be used by the minions when scheduling.

RUNNING THE SALT MASTER AS UNPRIVILEGED USER

While the default setup runs the Salt Master as the root user, it is generally wise to run servers as an unprivileged user. In Salt 0.9.10 the management of the running user was greatly improved, the only change needed is to alter the option user in the master configuration file and all salt system components will be updated to function under the new user when the master is started.

If running a version older that 0.9.10 then a number of files need to be owned by the user intended to run the master:

# chown -R <user> /var/cache/salt
# chown -R <user> /var/log/salt
# chown -R <user> /etc/salt/pki

TROUBLESHOOTING

The intent of the troubleshooting section is to introduce solutions to a number of common issues encountered by users and the tools that are available to aid in developing States and Salt code.

  Running in the Foreground

A great deal of information is available via the debug logging system, if you are having issues with minions connecting or not starting run the minion and/or master in the foreground:

# salt-master -l debug
# salt-minion -l debug

Anyone wanting to run Salt daemons via a process supervisor such as monit, runit, or supervisord, should omit the -d argument to the daemons and run them in the foreground.

  What Ports do the Master and Minion Need Open?

No ports need to be opened up on each minion. For the master, TCP ports 4505 and 4506 need to be open. If you've put both your Salt master and minion in debug mode and don't see an acknowledgment that your minion has connected, it could very well be a firewall.

You can check port connectivity from the minion with the nc command:

# nc -v -z salt.master.ip 4505
# nc -v -z salt.master.ip 4506

There is also a firewall configuration document that might help as well.

If you've enabled the right TCP ports on your operating system or Linux distribution's firewall and still aren't seeing connections, check that no additional access control system such as SELinux or AppArmor is blocking Salt.

  Using salt-call

The salt-call command was originally developed for aiding in the development of new Salt modules. Since then, many applications have been developed for running any Salt module locally on a minion. These range from the original intent of salt-call, development assistance, to gathering more verbose output from calls like state.highstate.

When developing the State Tree it is generally recommended to invoke state.highstate with salt-call. This displays far more information about the highstate execution than calling it remotely. For even more verbosity, increase the loglevel with the same argument as salt-minion:

salt-call -l debug state.highstate

  Too many open files

The salt-master needs at least 2 sockets per host that connects to it, one for the Publisher and one for response port. Thus, large installations may, upon scaling up the number of minions accessing a given master, encounter:

12:45:29,289 [salt.master    ][INFO    ] Starting Salt worker process 38
Too many open files
sock != -1 (tcp_listener.cpp:335)

The solution to this would be to check the number of files allowed to be opened by the user running salt-master (root by default):

[root@salt-master ~]# ulimit -n
1024

And modify that value to be at least equal to the number of minions x 2. This setting can be changed in limits.conf as the nofile value(s), and activated upon new a login of the specified user.

So, an environment with 1800 minions, would need 1800 x 2 = 3600 as a minimum.

  Salt Master Stops Responding

There are known bugs with ZeroMQ versions less than 2.1.11 which can cause the Salt master to not respond properly. If you're running a ZeroMQ version greater than or equal to 2.1.9, you can work around the bug by setting the sysctls net.core.rmem_max and net.core.wmem_max to 16777216. Next, set the third field in net.ipv4.tcp_rmem and net.ipv4.tcp_wmem to at least 16777216.

You can do it manually with something like:

# echo 16777216 > /proc/sys/net/core/rmem_max
# echo 16777216 > /proc/sys/net/core/wmem_max
# echo "4096 87380 16777216" > /proc/sys/net/ipv4/tcp_rmem
# echo "4096 87380 16777216" > /proc/sys/net/ipv4/tcp_wmem

Or with the following Salt state:

net.core.rmem_max:
  sysctl:
    - present
    - value: 16777216
net.core.wmem_max:
  sysctl:
    - present
    - value: 16777216
net.ipv4.tcp_rmem:
  sysctl:
    - present
    - value: 4096 87380 16777216
net.ipv4.tcp_wmem:
  sysctl:
    - present
    - value: 4096 87380 16777216

  Salt and SELinux

Currently there are no SELinux policies for Salt. For the most part Salt runs without issue when SELinux is running in Enforcing mode. This is because when the minion executes as a daemon the type context is changed to initrc_t. The problem with SELinux arises when using salt-call or running the minion in the foreground, since the type context stays unconfined_t.

This problem is generally manifest in the rpm install scripts when using the pkg module. Until a full SELinux Policy is available for Salt the solution to this issue is to set the execution context of salt-call and salt-minion to rpm_exec_t:

# chcon -t system_u:system_r:rpm_exec_t:s0 /usr/bin/salt-minion
# chcon -t system_u:system_r:rpm_exec_t:s0 /usr/bin/salt-call

This works well, because the rpm_exec_t context has very broad control over other types.

  Red Hat Enterprise Linux 5

Salt requires Python 2.6 or 2.7. Red Hat Enterprise Linux 5 and its variants come with Python 2.4 installed by default. When installing on RHEL 5 from the EPEL repository this is handled for you. But, if you run Salt from git, be advised that its dependencies need to be installed from EPEL and that Salt needs to be run with the python26 executable.

  Common YAML Gotchas

An extensive list of YAML idiosyncrasies has been compiled.

  Live Python Debug Output

If the minion or master seems to be unresponsive, a SIGUSR1 can be passed to the processes to display where in the code they are running. If encountering a situation like this, this debug information can be invaluable. First make sure the master of minion are running in the foreground:

# salt-master -l debug
# salt-minion -l debug

The pass the signal to the master or minion when it seems to be unresponsive:

killall -SIGUSR1 salt-master
killall -SIGUSR1 salt-minion

When filing an issue or sending questions to the mailing list for a problem with an unresponsive daemon this information can be invaluable.

YAML IDIOSYNCRASIES

One of Salt's strengths, the use of existing serialization systems for representing SLS data, can also backfire. YAML is a general purpose system and there are a number of things that would seem to make sense in an sls file that cause YAML issues. It is wise to be aware of these issues. While reports or running into them are generally rare they can still crop up at unexpected times.

  Spaces vs Tabs

YAML uses spaces, period. Do not use tabs in your SLS files! If strange errors are coming up in rendering SLS files, make sure to check that no tabs have crept in! In Vim, after enabling search highlighting with: :set hlsearch, you can check with the following key sequence in normal mode(you can hit ESC twice to be sure): /, Ctrl-v, Tab, then hit Enter. Also, you can convert tabs to 2 spaces by these commands in Vim: :set tabstop=2 expandtab and then :retab.

  Indentation

The suggested syntax for YAML files is to use 2 spaces for indentation, but YAML will follow whatever indentation system that the individual file uses. Indentation of two spaces works very well for SLS files given the fact that the data is uniform and not deeply nested.

  Nested Dicts (key=value)

When dicts: are more deeply nested, they no longer follow the same indentation logic. This is rarely something that comes up in Salt, since deeply nested options like these are discouraged when making State modules, but some do exist. A good example is the context and default options in the file.managed state:

/etc/http/conf/http.conf:
  file:
    - managed
    - source: salt://apache/http.conf
    - user: root
    - group: root
    - mode: 644
    - template: jinja
    - context:
        custom_var: "override"
    - defaults:
        custom_var: "default value"
        other_var: 123

Notice that the spacing used is 2 spaces, and that when defining the context and defaults options there is a 4 space indent. If only a 2 space indent is used then the information will not be loaded correctly. If using double spacing is not desirable, then a deeply nested dict can be declared with curly braces:

/etc/http/conf/http.conf:
  file:
    - managed
    - source: salt://apache/http.conf
    - user: root
    - group: root
    - mode: 644
    - template: jinja
    - context: {
      custom_var: "override" }
    - defaults: {
      custom_var: "default value",
      other_var: 123 }

  True/False, Yes/No, On/Off

PyYAML will load these values as boolean True or False. Un-capitalized versions will also be loaded as booleans (true, false, yes, no, on, and off). This can be especially problematic when constructing Pillar data. Make sure that your Pillars which need to use the string versions of these values are enclosed in quotes.

  Integers are Parsed as Integers

NOTE: This has been fixed in salt 0.10.0, as of this release passing an integer that is preceded by a 0 will be correctly parsed

When passing integers into an SLS file, they are passed as integers. This means that if a state accepts a string value and an integer is passed, that an integer will be sent. The solution here is to send the integer as a string.

This is best explained when setting the mode for a file:

/etc/vimrc:
  file:
    - managed
    - source: salt://edit/vimrc
    - user: root
    - group: root
    - mode: 644

Salt manages this well, since the mode is passed as 644, but if the mode is zero padded as 0644, then it is read by YAML as an integer and evaluated as an octal value, 0644 becomes 420. Therefore, if the file mode is preceded by a 0 then it needs to be passed as a string:

/etc/vimrc:
  file:
    - managed
    - source: salt://edit/vimrc
    - user: root
    - group: root
    - mode: '0644'

  YAML does not like Double Short Decs

If I can find a way to make YAML accept "Double Short Decs" then I will, since I think that double short decs would be awesome. So what is a "Double Short Dec"? It is when you declare a multiple short decs in one ID. Here is a standard short dec, it works great:

vim:
  pkg.installed

The short dec means that there are no arguments to pass, so it is not required to add any arguments, and it can save space.

YAML though, gets upset when declaring multiple short decs, for the record...

THIS DOES NOT WORK:

vim:
  pkg.installed
  user.present

Similarly declaring a short dec in the same ID dec as a standard dec does not work either...

ALSO DOES NOT WORK:

fred:
  user.present
  ssh_auth.present:
    - name: AAAAB3NzaC...
    - user: fred
    - enc: ssh-dss
    - require:
      - user: fred

The correct way is to define them like this:

vim:
  pkg.installed: []
  user.present: []
fred:
  user.present: []
  ssh_auth.present:
    - name: AAAAB3NzaC...
    - user: fred
    - enc: ssh-dss
    - require:
      - user: fred

Alternatively, they can be defined the "old way", or with multiple "full decs":

vim:
  pkg:
    - installed
  user:
    - present
fred:
  user:
    - present
  ssh_auth:
    - present
    - name: AAAAB3NzaC...
    - user: fred
    - enc: ssh-dss
    - require:
      - user: fred

  YAML support only plain ASCII

According to YAML specification, only ASCII characters can be used.

Within double-quotes, special characters may be represented with C-style escape sequences starting with a backslash ( \ ).

Examples:

- micro: "\u00b5"
- copyright: "\u00A9"
- A: "\x41"
- alpha: "\u0251"
- Alef: "\u05d0"

List of usable Unicode characters will help you to identify correct numbers.

Python can also be used to discover the Unicode number for a character:

repr(u"Text with wrong characters i need to figure out")

This shell command can find wrong characters in your SLS files:

find . -name '*.sls'  -exec  grep --color='auto' -P -n '[^\x00-\x7F]' \{} \;

  Developing Salt

There is a great need for contributions to salt and patches are welcome! The goal here is to make contributions clear, make sure there is a trail for where the code has come from, and most importantly, to give credit where credit is due!

There are a number of ways to contribute to salt development.

  Sending a Github pull request

This is the preferred method for contributions. Simply create a Github fork, commit changes to the fork, and then open up a pull request.

The following is an example (from Open Comparison Contributing Docs ) of an efficient workflow for forking, cloning, branching, committing, and sending a pull request for a github repository.

First, make a local clone of your github fork of the salt github repo and make edits and changes locally.

Then, create a new branch on your clone by entering the following commands:

git checkout -b fixed-broken-thing
Switched to a new branch 'fixed-broken-thing'

Choose a name for your branch that describes its purpose.

Now commit your changes to this new branch with the following command:

#add and commit all changes at once
git commit -a -m 'description of my fixes for the broken thing'

And then push your locally committed changes back up to GitHub:

git push --set-upstream origin fixed-broken-thing

Now go look at your fork of the salt repo on the GitHub website. The new branch will now be listed under the "Source" tab where it says "Switch Branches". Select the new branch from this list, and then click the "Pull request" button.

Put in a descriptive comment, and include links to any project issues related to the pull request.

The repo managers will be notified of your pull request and it will be reviewed. If a reviewer asks for changes, just make the changes locally in the same local feature branch, push them to GitHub, then add a comment to the discussion section of the pull request.

Note
    Travis-CI

    To make reviewing pull requests easier for the maintainers, please enable Travis-CI on the fork. Salt is already configured, so simply follow the first 2 steps on the Travis-CI Getting Started Doc.

  Keeping Salt Forks in Sync

Salt is advancing quickly. It is therefore critical to pull upstream changes from master into forks on a regular basis. Nothing is worse than putting in a days of hard work into a pull request only to have it rejected because it has diverged too far from master.

To pull in upstream changes:

# For ssh github
git remote add upstream git@github.com:saltstack/salt.git
git fetch upstream
# For https github
git remote add upstream https://github.com/saltstack/salt.git
git fetch upstream

To check the log to be sure that you actually want the changes, run this before merging:

git log upstream/develop

Then to accept the changes and merge into the current branch:

git merge upstream/develop

For more info, see Github Fork a Repo Guide or Open Comparison Contributing Docs

  Posting patches to the mailing list

Patches will also be accepted by email. Format patches using git format-patch and send them to the Salt users mailing list. The contributor will then get credit for the patch, and the Salt community will have an archive of the patch and a place for discussion.

  Installing Salt for development

Clone the repository using:

git clone https://github.com/saltstack/salt

Note
    tags

    Just cloning the repository is enough to work with Salt and make contributions. However, fetching additional tags from git is required to have Salt report the correct version for itself. To do this, first add the git repository as an upstream source:

    git remote add upstream http://github.com/saltstack/salt

    Fetching tags is done with the git 'fetch' utility:

    git fetch --tags upstream

Create a new virtualenv:

virtualenv /path/to/your/virtualenv

On Arch Linux, where Python 3 is the default installation of Python, use the virtualenv2 command instead of virtualenv.

Note
    Using system Python modules in the virtualenv

    To use already-installed python modules in virtualenv (instead of having pip download and compile new ones), run virtualenv --system-site-packages Using this method eliminates the requirement to install the salt dependencies again, although it does assume that the listed modules are all installed in the system PYTHONPATH at the time of virtualenv creation.

Activate the virtualenv:

source /path/to/your/virtualenv/bin/activate

Install Salt (and dependencies) into the virtualenv:

pip install M2Crypto    # Don't install on Debian/Ubuntu (see below)
pip install pyzmq PyYAML pycrypto msgpack-python jinja2 psutil
pip install -e ./salt   # the path to the salt git clone from above

Note
    Installing M2Crypto

    swig and libssl-dev are required to build M2Crypto. To fix the error command 'swig' failed with exit status 1 while installing M2Crypto, try installing it with the following command:

    env SWIG_FEATURES="-cpperraswarn -includeall -D__`uname -m`__ -I/usr/include/openssl" pip install M2Crypto

    Debian and Ubuntu systems have modified openssl libraries and mandate that a patched version of M2Crypto be installed. This means that M2Crypto needs to be installed via apt:

    apt-get install python-m2crypto

    This also means that pulling in the M2Crypto installed using apt requires using --system-site-packages when creating the virtualenv.

Note
    Installing psutil

    Python header files are required to build this module, otherwise the pip install will fail. If your distribution separates binaries and headers into separate packages, make sure that you have the headers installed. In most Linux distributions which split the headers into their own package, this can be done by installing the python-dev or python-devel package. For other platforms, the package will likely be similarly named.

Note
    Important note for those developing using RedHat variants

    For developers using a RedHat variant, be advised that the package provider for newer Redhat-based systems (yumpkg.py) relies on RedHat's python interface for yum. The variants that use this module to provide package support include the following:

•   RHEL and CentOS releases 6 and later

•   Fedora Linux releases 11 and later

•   Amazon Linux

    Developers using one of these systems should create the salt virtualenv using the --system-site-packages option to ensure that the correct modules are available.

Note
    Installing dependencies on OS X.

    You can install needed dependencies on OS X using homebrew or macports. See OS X Installation

  Running a self-contained development version

During development it is easiest to be able to run the Salt master and minion that are installed in the virtualenv you created above, and also to have all the configuration, log, and cache files contained in the virtualenv as well.

Copy the master and minion config files into your virtualenv:

mkdir -p /path/to/your/virtualenv/etc/salt
cp ./salt/conf/master /path/to/your/virtualenv/etc/salt/master
cp ./salt/conf/minion /path/to/your/virtualenv/etc/salt/minion

Edit the master config file:

1.  Uncomment and change the user: root value to your own user.

2.  Uncomment and change the root_dir: / value to point to /path/to/your/virtualenv.

3.  If you are running version 0.11.1 or older, uncomment and change the pidfile: /var/run/salt-master.pid value to point to /path/to/your/virtualenv/salt-master.pid.

4.  If you are also running a non-development version of Salt you will have to change the publish_port and ret_port values as well.

    Edit the minion config file:

1.  Repeat the edits you made in the master config for the user and root_dir values as well as any port changes.

2.  If you are running version 0.11.1 or older, uncomment and change the pidfile: /var/run/salt-minion.pid value to point to /path/to/your/virtualenv/salt-minion.pid.

3.  Uncomment and change the master: salt value to point at localhost.

4.  Uncomment and change the id: value to something descriptive like "saltdev". This isn't strictly necessary but it will serve as a reminder of which Salt installation you are working with.

Note
    Using salt-call with a Standalone Minion

    If you plan to run salt-call with this self-contained development environment in a masterless setup, you should invoke salt-call with -c /path/to/your/virtualenv/etc/salt so that salt can find the minion config file. Without the -c option, Salt finds its config files in /etc/salt.

Start the master and minion, accept the minon's key, and verify your local Salt installation is working:

cd /path/to/your/virtualenv
salt-master -c ./etc/salt -d
salt-minion -c ./etc/salt -d
salt-key -c ./etc/salt -L
salt-key -c ./etc/salt -A
salt -c ./etc/salt '*' test.ping

Running the master and minion in debug mode can be helpful when developing. To do this, add -l debug to the calls to salt-master and salt-minion. If you would like to log to the console instead of to the log file, remove the -d.

Once the minion starts, you may see an error like the following:

zmq.core.error.ZMQError: ipc path "/path/to/your/virtualenv/var/run/salt/minion/minion_event_7824dcbcfd7a8f6755939af70b96249f_pub.ipc" is longer than 107 characters (sizeof(sockaddr_un.sun_path)).

This means the the path to the socket the minion is using is too long. This is a system limitation, so the only workaround is to reduce the length of this path. This can be done in a couple different ways:

1.  Create your virtualenv in a path that is short enough.

2.  Edit the sock_dir minion config variable and reduce its length. Remember that this path is relative to the value you set in root_dir.

    NOTE: The socket path is limited to 107 characters on Solaris and Linux, and 103 characters on BSD-based systems.

Note
    File descriptor limits

    Ensure that the system open file limit is raised to at least 2047:

    # check your current limit
    ulimit -n
    # raise the limit. persists only until reboot
    # use 'limit descriptors 2047' for c-shell
    ulimit -n 2047

    To set file descriptors on OSX, refer to the OS X Installation instructions.

  Running the tests

You will need mock to run the tests:

pip install mock

If you are on Python < 2.7 then you will also need unittest2:

pip install unittest2

Finally you use setup.py to run the tests with the following command:

./setup.py test

For greater control while running the tests, please try:

./tests/runtests.py -h

  Editing and previewing the documention

You need sphinx-build command to build the docs. In Debian/Ubuntu this is provided in the python-sphinx package. You can also install this directly to your virtual environment using pip:

pip install Sphinx

Change to salt documention directory, then:

cd doc; make html

•   The docs then are built in the docs/_build/html/ folder. If you make changes and want to see the results, make html again.

•   The docs use reStructuredText for markup. See a live demo at http://rst.ninjs.org/.

•   The help information on each module or state is culled from the python code that runs for that piece. Find them in salt/modules/ or salt/states/.

•   If you are developing using Arch Linux (or any other distribution for which Python 3 is the default Python installation), then sphinx-build may be named sphinx-build2 instead. If this is the case, then you will need to run the following make command:

    make SPHINXBUILD=sphinx-build2 html

SALT BASED PROJECTS

A number of unofficial open source projects, based on Salt, or written to enhance Salt have been created.

  Salt Sandbox

Created by Aaron Bull Schaefer, aka "elasticdog".

https://github.com/elasticdog/salt-sandbox

Salt Sandbox is a multi-VM Vagrant-based Salt development environment used for creating and testing new Salt state modules outside of your production environment. It's also a great way to learn firsthand about Salt and its remote execution capabilities.

Salt Sandbox will set up three separate virtual machines:

•   salt.example.com - the Salt master server

•   minion1.example.com - the first Salt minion machine

•   minion2.example.com - the second Salt minion machine

    These VMs can be used in conjunction to segregate and test your modules based on node groups, top file environments, grain values, etc. You can even test modules on different Linux distributions or release versions to better match your production infrastructure.

SALT EVENT SYSTEM

Salt 0.9.10 introduced the Salt Event System. This system is used to fire off events enabling third party applications or external processes to react to behavior within Salt.

The event system is comprised of a few components, the event sockets which publish events, and the event library which can listen to events and send events into the salt system.

  Listening for Events

The event system is accessed via the event library and can only be accessed by the same system user that Salt is running as. To listen to events a SaltEvent object needs to be created and then the get_event function needs to be run. The SaltEvent object needs to know the location that the Salt Unix sockets are kept. In the configuration this is the sock_dir option. The sock_dir option defaults to "/var/run/salt/master" on most systems.

The following code will check for a single event:

import salt.utils.event
event = salt.utils.event.MasterEvent('/var/run/salt/master')
data = event.get_event()

Events will also use a "tag". A "tag" allows for events to be filtered. By default all events will be returned, but if only authentication events are desired, then pass the tag "auth". Also, the get_event method has a default poll time assigned of 5 seconds, to change this time set the "wait" option. This example will only listen for auth events and will wait for 10 seconds instead of the default 5.

import salt.utils.event
event = salt.utils.event.MasterEvent('/var/run/salt/master')
data = event.get_event(wait=10, tag='auth')

Instead of looking for a single event, the iter_events method can be used to make a generator which will continually yield salt events. The iter_events method also accepts a tag, but not a wait time:

import salt.utils.event
event = salt.utils.event.MasterEvent('/var/run/salt/master')
for data in event.iter_events(tag='auth'):
    print(data)

RUNNING THE TESTS

To run the tests, use tests/runtests.py, see --help for more info.

Examples:

•   To run all tests: sudo ./tests/runtests.py

•   Run unit tests only: sudo ./tests/runtests.py --unit-tests

    You will need 'mock' (https://pypi.python.org/pypi/mock) in addition to salt requirements in order to run the tests.

  Writing Tests

Salt uses a test platform to verify functionality of components in a simple way. Two testing systems exist to enable testing salt functions in somewhat real environments. The two subsystems available are integration tests and unit tests.

Salt uses the python standard library unittest2 system for testing.

INTEGRATION TESTS

The integration tests start up a number of salt daemons to test functionality in a live environment. These daemons include 2 salt masters, 1 syndic and 2 minions. This allows for the syndic interface to be tested and master/minion communication to be verified. All of the integration tests are executed as live salt commands sent through the started daemons.

•   Writing integration tests

    Integration tests are particularly good at testing modules, states and shell commands.

UNIT TESTS

Direct unit tests are also available, these tests are good for internal functions.

INTEGRATION TESTS

The Salt integration tests come with a number of classes and methods which allow for components to be easily tested. These classes are generally inherited from and provide specific methods for hooking into the running integration test environment created by the integration tests.

It is noteworthy that since integration tests validate against a running environment that they are generally the preferred means to write tests.

The integration system is all located under tests/integration in the Salt source tree.

  Integration Classes

The integration classes are located in tests/integration/__init__.py and can be extended therein. There are three classes available to extend:

  ModuleCase

Used to define executions run via the master to minions and to call single modules and states.

The available methods are as follows:

run_function:
    Run a single salt function and condition the return down to match the behavior of the raw function call. This will run the command and only return the results from a single minion to verify.

state_result:
    Return the result data from a single state return

run_state:
    Run the state.single command and return the state return structure

  SyndicCase

Used to execute remote commands via a syndic, only used to verify the capabilities of the Syndic.

The available methods are as follows:

run_function:
    Run a single salt function and condition the return down to match the behavior of the raw function call. This will run the command and only return the results from a single minion to verify.

  ShellCase

Shell out to the scripts which ship with Salt.

The available methods are as follows:

run_script:
    Execute a salt script with the given argument string

run_salt:
    Execute the salt command, pass in the argument string as it would be passed on the command line.

run_run:
    Execute the salt-run command, pass in the argument string as it would be passed on the command line.

run_run_plus:
    Execute Salt run and the salt run function and return the data from each in a dict

run_key:
    Execute the salt-key command, pass in the argument string as it would be passed on the command line.

run_cp:
    Execute salt-cp, pass in the argument string as it would be passed on the command line.

run_call:
    Execute salt-call, pass in the argument string as it would be passed on the command line.

  Examples

  Module Example via ModuleCase Class

Import the integration module, this module is already added to the python path by the test execution. Inherit from the integration.ModuleCase class. The tests that execute against salt modules should be placed in the tests/integration/modules directory so that they will be detected by the test system.

Now the workhorse method run_function can be used to test a module:

import os
import integration
class TestModuleTest(integration.ModuleCase):
    '''
    Validate the test module
    '''
    def test_ping(self):
        '''
        test.ping
        '''
        self.assertTrue(self.run_function('test.ping'))
    def test_echo(self):
        '''
        test.echo
        '''
        self.assertEqual(self.run_function('test.echo', ['text']), 'text')

ModuleCase can also be used to test states, when testing states place the test module in the tests/integration/states directory. The state_result and the run_state methods are the workhorse here:

import os
import shutil
import integration
HFILE = os.path.join(integration.TMP, 'hosts')
class HostTest(integration.ModuleCase):
    '''
    Validate the host state
    '''
    def setUp(self):
        shutil.copyfile(os.path.join(integration.FILES, 'hosts'), HFILE)
        super(HostTest, self).setUp()
    def tearDown(self):
        if os.path.exists(HFILE):
            os.remove(HFILE)
        super(HostTest, self).tearDown()
    def test_present(self):
        '''
        host.present
        '''
        name = 'spam.bacon'
        ip = '10.10.10.10'
        ret = self.run_state('host.present', name=name, ip=ip)
        result = self.state_result(ret)
        self.assertTrue(result)
        with open(HFILE) as fp_:
            output = fp_.read()
            self.assertIn('{0}\t\t{1}'.format(ip, name), output)

The above example also demonstrates using the integration files and the integration state tree. The variable integration.FILES will point to the directory used to store files that can be used or added to to help enable tests that require files. The location integration.TMP can also be used to store temporary files that the test system will clean up when the execution finishes.

The integration state tree can be found at tests/integration/files/file/base. This is where the referenced host.present sls file resides.

  Shell Example via ShellCase

Validating the shell commands can be done via shell tests. Here are some examples:

import sys
import shutil
import tempfile
import integration
class KeyTest(integration.ShellCase):
    '''
    Test salt-key script
    '''
    _call_binary_ = 'salt-key'
    def test_list(self):
        '''
        test salt-key -L
        '''
        data = self.run_key('-L')
        expect = [
                'Unaccepted Keys:',
                'Accepted Keys:',
                'minion',
                'sub_minion',
                'Rejected:', '']
        self.assertEqual(data, expect)

This example verifies that the salt-key command executes and returns as expected by making use of the run_key method.

All shell tests should be placed in the tests/integraion/shell directory.

REACTOR SYSTEM

Salt version 0.11.0 introduced the reactor system. The premise behind the reactor system is that with Salt's events and the ability to execute commands a logic engine could be put in place to allow events to trigger actions, or more accurately, reactions.

This system binds sls files to event tags on the master. These sls files then define reactions. This means that the reactor system has two parts. First, the reactor option needs to be set in the master configuration file. The reactor option allows for event tags to be associated with sls reaction files. Second, these reaction files use highdata (like the state system) to define reactions to be executed.

  Event System

A basic understanding of the event system is required to understand reactors. The event system is a local ZeroMQ PUB interface which fires salt events. This event bus is an open system used for sending information notifying Salt and other systems about operations.

The event system fires events with a very specific criteria. Every event has a tag which is comprised of a maximum of 20 characters. Event tags allow for fast top level filtering of events. In addition to the tag, an event has a data structure. This data structure is a dict containing information about the event.

  Mapping Events to Reactor SLS Files

The event tag and data are both critical when working with the reactor system. In the master configuration file under the reactor option, tags are associated with lists of reactor sls formulas (globs can be used for matching):

reactor:
  - 'auth':
    - /srv/reactor/authreact1.sls
    - /srv/reactor/authreact2.sls
  - 'minion_start':
    - /srv/reactor/start.sls

When an event with a tag of auth is fired the reactor will catch the event and render the two listed files. The rendered files are standard sls files, so by default they are yaml + Jinja. The Jinja is packed with a few data structures similar to state and pillar sls files. The data available is found in the tag and data variables. The tag variable is just the tag in the fired event and the data variable is the event's data dict. Here is a simple reactor sls:

{% if data['id'] == 'mysql1' %}
highstate_run:
  cmd.state.highstate:
    - tgt: mysql1
{% endif %}

This simple reactor file uses Jinja to further refine the reaction to be made. If the id in the event data is mysql1 (if the name of the minion is mysql1) then the following reaction is defined. The same data structure and compiler used for the state system is used for the reactor system. The only difference is that the data is matched up to the salt command API and the runner system. In this example a command is published to the mysql1 minion with a function of state.highstate. Similarly, a runner can be called:

{% if data['data']['overstate'] == 'refresh' %}
overstate_run:
  runner.state.over
{% endif %}

This example will execute the state.overstate runner and initiate an overstate execution.

  Understanding the Structure of Reactor Formulas

While the reactor system uses the same data structure as the state system, this data does not translate the same way to operations. In state formulas information is mapped to the state functions, but in the reactor system information is mapped to a number of available subsystems on the master. These systems are the LocalClient and the Runners. The state declaration field takes a reference to the function to call in each interface. So to trigger a salt-run call the state declaration field will start with runner, followed by the runner function to call. This means that a call to what would be on the command line salt-run manage.up will be runner.manage.up. An example of this in a reactor formula would look like this:

manage_up:
  runner.manage.up

If the runner takes arguments then they can be specified as well:

overstate_dev_env:
  runner.state.over:
    - env: dev

Executing remote commands maps to the LocalClient interface which is used by the salt command. This interface more specifically maps to the cmd_async method inside of the LocalClient class. This means that the arguments passed are being passed to the cmd_async method, not the remote method. The field starts with cmd to use the LocalClient subsystem. The result is that to execute a remote command it looks like this:

clean_tmp:
  cmd.cmd.run:
    - tgt: '*'
    - arg:
      - rm -rf /tmp/*

The arg option takes a list of arguments as they would be presented on the command line, so the above declaration is the same as running this salt command:

salt \* cmd.run 'rm -rf /tmp/*'

SALT CODING STYLE

Salt is developed with a certain coding style, while the style is dominantly PEP-08 it is not completely PEP-08. It is also noteworthy that a few development techniques are also employed which should be adhered to. In the end, the code is made to be "Salty".

Most importantly though, we will accept code that violates the coding style and KINDLY ask the contributor to fix it, or go ahead and fix the code on behalf of the contributor. Coding style is NEVER grounds to reject code contributions, and is never grounds to talk down to another member of the community (There are no grounds to treat others without respect, especially people working to improve Salt)!!

  Strings

Salt follows a few rules when formatting strings:

  Single Quotes

In Salt, all strings use single quotes unless there is a good reason not to. This means that docstrings use single quotes, standard strings use single quotes etc.:

def foo():
    '''
    A function that does things
    '''
    name = 'A name'
    return name

  Formatting Strings

All strings which require formatting should use the .format string method:

data = 'some text'
more = '{0} and then some'.format(data)

Make sure to use indices or identifiers in the format brackets, since empty brackets are not supported by python 2.6.

Please do NOT use printf formatting.

  Docstring Conventions

Docstrings should always add a newline, docutils takes care of the new line and it makes the code cleaner and more vertical:

GOOD:

def bar():
    '''
    Here lies a docstring with a newline after the quotes and is the salty
    way to handle it! Vertical code is the way to go!
    '''
    return

BAD:

def baz():
    '''This is not ok!'''
    return

  Imports

Salt code prefers importing modules and not explicit functions. This is both a style and functional preference. The functional preference originates around the fact that the module import system used by pluggable modules will include callable objects (functions) that exist in the direct module namespace. This is not only messy, but may unintentionally expose code python libs to the Salt interface and pose a security problem.

To say this more directly with an example, this is GOOD:

import os
def minion_path():
    path = os.path.join(self.opts['cachedir'], 'minions')
    return path

This on the other hand is DISCOURAGED:

from os.path import join
def minion_path():
path = join(self.opts['cachedir'], 'minions')
return path

The time when this is changed is for importing exceptions, generally directly importing exceptions is preferred:

This is a good way to import exceptions:

from salt.exceptions import CommandExecutionError

  Vertical is Better

When writing Salt code, vertical code is generally preferred. This is not a hard rule but more of a guideline. As PEP-08 specifies Salt code should not exceed 79 characters on a line, but it is preferred to separate code out into more newlines in some cases for better readability:

import os
os.chmod(
        os.path.join(self.opts['sock_dir'],
            'minion_event_pub.ipc'),
        448
        )

Where there are more line breaks, this is also apparent when constructing a function with many arguments, something very common in state functions for instance:

def managed(name,
        source=None,
        source_hash='',
        user=None,
        group=None,
        mode=None,
        template=None,
        makedirs=False,
        context=None,
        replace=True,
        defaults=None,
        env=None,
        backup='',
        **kwargs):

  Code Churn

Many pull requests have been submitted that only churn code in the name of PEP-08. Code churn is a leading source of bugs and is strongly discouraged. While style fixes are encouraged they should be isolated to a single file per commit, and the changes should be legitimate, if there are any questions about whether a style change is legitimate please reference this document and the official PEP-08 (http://www.python.org/dev/peps/pep-0008/) document before changing code. Many claims that a change is PEP-08 have been invalid, please double check before committing fixes.

SALT STACK GIT POLICY

The Salt Stack team follows a git policy to maintain stability and consistency with the repository. The git policy has been developed to encourage contributions and make contributing to Salt as easy as possible. Code contributors to Salt Stack projects DO NOT NEED TO READ THIS DOCUMENT, because all contributions come into Salt Stack via a single gateway to make it as easy as possible for contributors to give us code.

The primary rule of git management in Salt Stack is to make life easy on contributors and developers to send in code. Simplicity is always a goal!

  New Code Entry

All new Salt Stack code is posted to the develop branch, this is the single point of entry. The only exception here is when a bugfix to develop cannot be cleanly merged into a release branch and the bugfix needs to be rewritten for the release branch.

  Release Branching

Salt Stack maintains two types of releases, Feature Releases and Point Releases. A feature release is managed by incrementing the first or second release point number, so 0.10.5 -> 0.11.0 signifies a feature release and 0.11.0 -> 0.11.1 signifies a point release, also a hypothetical 0.42.7 -> 1.0.0 would also signify a feature release.

  Feature Release Branching

Each feature release is maintained in a dedicated git branch derived from the last applicable release commit on develop. All file changes relevant to the feature release will be completed in the develop branch prior to the creation of the feature release branch. The feature release branch will be named after the relevant numbers to the feature release, which constitute the first two numbers. This means that the release branch for the 0.11.0 series is named 0.11.

A feature release branch is created with the following command:

# git checkout -b 0.11 # From the develop branch
# git push origin 0.11

  Point Releases

Each point release is derived from its parent release branch. Constructing point releases is a critical aspect of Salt development and is managed by members of the core development team. Point releases comprise bug and security fixes which are cherry picked from develop onto the aforementioned release branch. At the time when a core developer accepts a pull request a determination needs to be made if the commits in the pull request need to be backported to the release branch. Some simple criteria are used to make this determination:

•   Is this commit fixing a bug? Backport

•   Does this commit change or add new features in any way? Don't backport

•   Is this a PEP8 or code cleanup commit? Don't backport

•   Does this commit fix a security issue? Backport

    Determining when a point release is going to be made is up to the project leader (Thomas Hatch). Generally point releases are made every 1-2 weeks or if there is a security fix they can be made sooner.

    The point release is only designated by tagging the commit on the release branch with release number using the existing convention (version 0.11.1 is tagged with v0.11.1). From the tag point a new source tarball is generated and published to PyPI, and a release announcement is made.

SALT DEVELOPMENT GUIDELINES

  Dunder Dictionaries

Salt provides several special "dunder" dictionaries as a convenience for Salt development. These include __opts__, __context__, __salt__, and others. This document will describe each dictionary and detail where they exist and what information and/or functionality they provide.

  __context__

__context__ exists in state modules and execution modules.

During a state run the __context__ dictionary persists across all states that are run and then is destroyed when the state ends.

When running an execution module __context__ persists across all module executions until the modules are refreshed; such as when saltutils.sync_all or state.highstate are executed.

A great place to see how to use __context__ is in the cp.py module in salt/modules/cp.py. The fileclient authenticates with the master when it is instantiated and then is used to copy files to the minion. Rather than create a new fileclient for each file that is to be copied down, one instance of the fileclient is instantiated in the __context__ dictionary and is reused for each file. Here is an example from salt/modules/cp.py:

if not 'cp.fileclient' in __context__:
    __context__['cp.fileclient'] = salt.fileclient.get_file_client(__opts__)

Note
    Because __context__ may or may not have been destroyed, always be sure to check for the existence of the key in __context__ and generate the key before using it.

  Package Providers

This page contains guidelines for writing package providers.

  Package Functions

One of the most important features of Salt is package management. There is no shortage of package managers, so in the interest of providing a consistent experience in pkg states, there are certain functions that should be present in a package provider. Note that these are subject to change as new features are added or existing features are enhanced.

  list_pkgs

This function should declare an empty dict, and then add packages to it by calling pkg_resource.add_pkg, like so:

__salt__['pkg_resource.add_pkg'](ret, name, version)

The last thing that should be done before returning is to execute pkg_resource.sort_pkglist. This function does not presently do anything to the return dict, but will be used in future versions of Salt.

__salt__['pkg_resource.sort_pkglist'](ret)

list_pkgs returns a dictionary of installed packages, with the keys being the package names and the values being the version installed. Example return data:

{'foo': '1.2.3-4',
 'bar': '5.6.7-8'}

  latest_version

Accepts an arbitrary number of arguments. Each argument is a package name. The return value for a package will be an empty string if the package is not found or if the package is up-to-date. The only case in which a non-empty string is returned is if the package is available for new installation (i.e. not already installed) or if there is an upgrade available.

If only one argument was passed, this function return a string, otherwise a dict of name/version pairs is returned.

This function must also accept **kwargs, in order to receive the fromrepo and repo keyword arguments from pkg states. Where supported, these arguments should be used to find the install/upgrade candidate in the specified repository. The fromrepo kwarg takes precedence over repo, so if both of those kwargs are present, the repository specified in fromrepo should be used. However, if repo is used instead of fromrepo, it should still work, to preserve backwards compatibility with older versions of Salt.

  version

Like latest_version, accepts an arbitrary number of arguments and returns a string if a single package name was passed, or a dict of name/value pairs if more than one was passed. The only difference is that the return values are the currently-installed versions of whatever packages are passed. If the package is not installed, an empty string is returned for that package.

  upgrade_available

Deprecated and destined to be removed. For now, should just do the following:

return __salt__['pkg.latest_version'](name) != ''

  install

The following arguments are required and should default to None:

1.  name (for single-package pkg states)

2.  pkgs (for multiple-package pkg states)

3.  sources (for binary package file installation)

    The first thing that this function should do is call pkg_resource.parse_targets (see below). This function will convert the SLS input into a more easily parsed data structure. pkg_resource.parse_targets may need to be modified to support your new package provider, as it does things like parsing package metadata which cannot be done for every package management system.

    pkg_params, pkg_type = __salt__['pkg_resource.parse_targets'](name,
                                                                  pkgs,
                                                                  sources)

    Two values will be returned to the install function. The first of them will be a dictionary. The keys of this dictionary will be package names, though the values will differ depending on what kind of installation is being done:

•   If name was provided (and pkgs was not), then there will be a single key in the dictionary, and its value will be None. Once the data has been returned, if the version keyword argument was provided, then it should replace the None value in the dictionary.

•   If pkgs was provided, then name is ignored, and the dictionary will contain one entry for each package in the pkgs list. The values in the dictionary will be None if a version was not specified for the package, and the desired version if specified. See the Multiple Package Installation Options section of the pkg.installed state for more info.

•   If sources was provided, then name is ignored, and the dictionary values will be the path/URI for the package.

    The second return value will be a string with two possible values: repository or file. The install function can use this value (if necessary) to build the proper command to install the targeted package(s).

    Both before and after the installing the target(s), you should run list_pkgs to obtain a list of the installed packages. You should then return the output of pkg_resource.find_changes:

    return __salt__['pkg_resource.find_changes'](old, new)

  remove

Removes the passed package and return a list of the packages removed.

  Package Repo Functions

There are some functions provided by pkg which are specific to package repositories, and not to packages themselves. When writing modules for new package managers, these functions should be made available as stated below, in order to provide compatibility with the pkgrepo state.

All repo functions should accept a basedir option, which defines which directory repository configuration should be found in. The default for this is dictated by the repo manager that is being used, and rarely needs to be changed.

basedir = '/etc/yum.repos.d'
__salt__['pkg.list_repos'](basedir)

  list_repos

Lists the repositories that are currently configured on this system.

__salt__['pkg.list_repos']()

Returns a dictionary, in the following format:

{'reponame': 'config_key_1': 'config value 1',
             'config_key_2': 'config value 2',
             'config_key_3': ['list item 1 (when appropriate)',
                              'list item 2 (when appropriate)]}

  get_repo

Displays all local configuration for a specific repository.

__salt__['pkg.get_repo'](repo='myrepo')

The information is formatted in much the same way as list_repos, but is specific to only one repo.

{'config_key_1': 'config value 1',
 'config_key_2': 'config value 2',
 'config_key_3': ['list item 1 (when appropriate)',
                  'list item 2 (when appropriate)]}

  del_repo

Removes the local configuration for a specific repository. Requires a repo argument, which must match the locally configured name. This function returns a string, which informs the user as to whether or not the operation was a success.

__salt__['pkg.del_repo'](repo='myrepo')

  mod_repo

Modify the local configuration for one or more option for a configured repo. This is also the way to create new repository configuration on the local system; if a repo is specified which does not yet exist, it will be created.

The options specified for this function are specific to the system; please refer to the documentation for your specific repo manager for specifics.

__salt__['pkg.mod_repo'](repo='myrepo', url='http://myurl.com/repo')

  Low-Package Functions

In general, the standard package functions as describes above will meet your needs. These functions use the system's native repo manager (for instance, yum or the apt tools). In most cases, the repo manager is actually separate from the package manager. For instance, yum is usually a front-end for rpm, and apt is usually a front-end for dpkg. When possible, the package functions that use those package managers directly should do so through the low package functions.

It is normal and sane for pkg to make calls to lowpkgs, but lowpkg must never make calls to pkg. This is affects functions which are required by both pkg and lowpkg, but the technique in pkg is more performant than what is available to lowpkg. When this is the case, the lowpkg function that requires that technique must still use the lowpkg version.

  list_pkgs

Returns a dict of packages installed, including the package name and version. Can accept a list of packages; if none are specified, then all installed packages will be listed.

installed = __salt__['lowpkg.list_pkgs']('foo', 'bar')

Example output:

{'foo': '1.2.3-4',
 'bar': '5.6.7-8'}

  verify

Many (but not all) package management systems provide a way to verify that the files installed by the package manager have or have not changed. This function accepts a list of packages; if none are specified, all packages will be included.

installed = __salt__['lowpkg.verify']('httpd')

Example output:

{'/etc/httpd/conf/httpd.conf': {'mismatch': ['size', 'md5sum', 'mtime'],
                                'type': 'config'}}

  file_list

Lists all of the files installed by all packages specified. If not packages are specified, then all files for all known packages are returned.

installed = __salt__['lowpkg.file_list']('httpd', 'apache')

This function does not return which files belong to which packages; all files are returned as one giant list (hence the file_list function name. However, This information is still returned inside of a dict, so that it can provide any errors to the user in a sane manner.

{'errors': ['package apache is not installed'],
  'files': ['/etc/httpd',
            '/etc/httpd/conf',
            '/etc/httpd/conf.d',
            '...SNIP...']}

  file_dict

Lists all of the files installed by all packages specified. If not packages are specified, then all files for all known packages are returned.

installed = __salt__['lowpkg.file_dict']('httpd', 'apache', 'kernel')

Unlike file_list, this function will break down which files belong to which packages. It will also return errors in the same manner as file_list.

{'errors': ['package apache is not installed'],
 'packages': {'httpd': ['/etc/httpd',
                        '/etc/httpd/conf',
                        '...SNIP...'],
              'kernel': ['/boot/.vmlinuz-2.6.32-279.el6.x86_64.hmac',
                         '/boot/System.map-2.6.32-279.el6.x86_64',
                         '...SNIP...']}}

INTRODUCTION TO EXTENDING SALT

Salt is made to be used, and made to be extended. The primary goal of Salt is to provide a foundation which can be used to solve problems. And the goal of Salt is to not assume what those problems might be.

One of the greatest benefit of developing Salt has been the vast array of ways in which people have wanted to use it, while the original intention was as a communication layer for a cloud controller Salt has been extended to facilitate so much more.

  Client API

The primary interface used to extend Salt, is to simply use it. Salt executions can be called via the Salt client API, making programming master side solutions with Salt is easy.

  Adding Loadable Plugins

Salt is comprised of a core platform that loads many types of easy to write plugins. The idea is to enable all of the breaking points in the Salt processes to have a point of pluggable interaction. This means that all of the main features of Salt can be extended, modified or used.

The breaking points and helping interfaces span from convenience master side executions to manipulating the flow of how data is handled by Salt.

  Minion Execution Modules

The minion execution modules or just modules are the core to what Salt is and does. These modules are found in:

https://github.com/saltstack/salt/blob/develop/salt/modules

These modules are what is called by the Salt command line and the salt client API. Adding modules is done by simply adding additional Python modules to the modules directory and restarting the minion.

  Grains

Salt grains, or "grains of truth" are bits of static information that are generated when the minion starts. This information is useful when determining what package manager to default to, or where certain configuration files are stored on the minion.

The Salt grains are the interface used for auto detection and dynamic assignment of execution modules and types to specific Salt minions.

The code used to generate the Salt grains can be found here:

https://github.com/saltstack/salt/blob/develop/salt/grains

  States

Salt supports state enforcement, this makes Salt a high speed and very efficient solution for system configuration management.

States can be easily added to Salt by dropping a new state module in:

https://github.com/saltstack/salt/blob/develop/salt/states

  Renderers

Salt states are controlled by simple data structures, these structures can be abstracted in a number of ways. While the default is to be in a YAML file wrapped in a jinja template, any abstraction can be used. This means that any format that can be dreamed is possible, so long as a renderer is written for it.

The existing renderers can be found here:

https://github.com/saltstack/salt/blob/develop/salt/renderers

  Returners

The Salt commands all produce a return value, that return value is sent to the Salt master by default, but it can be sent anywhere. The returner interface makes it programmatically possible for the information to be sent to anything from an SQL or NoSQL database, to a custom application made to use Salt.

The existing returners can be found here:

https://github.com/saltstack/salt/blob/develop/salt/returners

  Runners

Sometimes a certain application can be made to execute and run from the existing Salt command line. This is where the Salt runners come into play. The Salt Runners what is called by the Salt-run command and are meant to act as a generic interface for encapsulating master side executions.

Existing Salt runners are located here:

https://github.com/saltstack/salt/blob/develop/salt/runners

MODULES

Salt modules are the functions called by the salt command.

See also

    Full list of builtin modules

    Salt ships with many modules that cover a wide variety of tasks.

  Modules Are Easy to Write!

Salt modules are amazingly simple to write. Just write a regular Python module or a regular Cython module and place it in the salt/modules directory. You can also place them in a directory called _modules/ within the file_roots specified by the master config file, and they will be synced to the minions when state.highstate is run, or by executing the saltutil.sync_modules or saltutil.sync_all functions.

Since Salt modules are just Python/Cython modules, there are no restraints on what you can put inside of a Salt module. If a Salt module has errors and cannot be imported, the Salt minion will continue to load without issue and the module with errors will simply be omitted.

If adding a Cython module the file must be named <modulename>.pyx so that the loader knows that the module needs to be imported as a Cython module. The compilation of the Cython module is automatic and happens when the minion starts, so only the *.pyx file is required.

  Cross Calling Modules

All of the Salt modules are available to each other, and can be "cross called". This means that, when creating a module, functions in modules that already exist can be called.

The variable __salt__ is packed into the modules after they are loaded into the Salt minion. This variable is a Python dictionary of all of the Salt functions, laid out in the same way that they are made available to the Salt command.

Salt modules can be cross called by accessing the value in the __salt__ dict:

def foo(bar):
    return __salt__['cmd.run'](bar)

This code will call the Salt cmd module's run function and pass the argument bar.

  Preloaded Modules Data

When interacting with modules often it is nice to be able to read information dynamically about the minion, or load in configuration parameters for a module. Salt allows for different types of data to be loaded into the modules by the minion, as of this writing Salt loads information gathered from the Salt Grains system and from the minion configuration file.

  Grains Data

The Salt minion detects information about the system when started. This allows for modules to be written dynamically with respect to the underlying hardware and operating system. This information is referred to as Salt Grains, or "grains of salt". The Grains system was introduced to replace Facter, since relying on a Ruby application from a Python application was both slow and inefficient. Grains support replaces Facter in all Salt releases after 0.8

The values detected by the Salt Grains on the minion are available in a dict named __grains__ and can be accessed from within callable objects in the Python modules.

To see the contents of the grains dict for a given system in your deployment run the grains.items() function:

salt 'hostname' grains.items

To use the __grains__ dict simply call it as a Python dict from within your code, an excellent example is available in the Grains module: salt.modules.grains.

  Module Configuration

Since parameters for configuring a module may be desired, Salt allows for configuration information stored in the main minion config file to be passed to the modules.

Since the minion configuration file is a YAML document, arbitrary configuration data can be passed in the minion config that is read by the modules. It is strongly recommended that the values passed in the configuration file match the module. This means that a value intended for the test module should be named test.<value>.

Configuration also requires that default configuration parameters need to be loaded as well. This can be done simply by adding the __opts__ dict to the top level of the module.

The test module contains usage of the module configuration, and the default configuration file for the minion contains the information and format used to pass data to the modules. salt.modules.test, conf/minion.

  Printout Configuration

Since module functions can return different data, and the way the data is printed can greatly change the presentation, Salt has a printout configuration.

When writing a module the __outputter__ dict can be declared in the module. The __outputter__ dict contains a mapping of function name to Salt Outputter.

__outputter__ = {
                'run': 'txt'
                }

This will ensure that the text outputter is used.

  Virtual Modules

Sometimes a module should be presented in a generic way. A good example of this can be found in the package manager modules. The package manager changes from one operating system to another, but the Salt module that interfaces with the package manager can be presented in a generic way.

The Salt modules for package managers all contain a __virtual__ function which is called to define what systems the module should be loaded on.

The __virtual__ function is used to return either a string or False. If False is returned then the module is not loaded, if a string is returned then the module is loaded with the name of the string.

This means that the package manager modules can be presented as the pkg module regardless of what the actual module is named.

The package manager modules are the best example of using the __virtual__ function: https://github.com/saltstack/salt/blob/develop/salt/modules/pacman.py https://github.com/saltstack/salt/blob/develop/salt/modules/yumpkg.py https://github.com/saltstack/salt/blob/develop/salt/modules/apt.py

  Documentation

Salt modules are self documenting, the sys.doc() function will return the documentation for all available modules:

salt '*' sys.doc

This function simple prints out the docstrings found in the modules, when writing Salt modules, please follow the formatting conventions for docstrings as they appear in the other modules.

  Adding Documentation to Salt Modules

Since life is much better with documentation, it is strongly suggested that all Salt modules have documentation added. Any Salt modules submitted for inclusion in the main distribution of Salt will be required to have documentation.

Documenting Salt modules is easy! Just add a Python docstring to the function.

def spam(eggs):
    '''
    A function to make some spam with eggs!
    CLI Example::
        salt '*' test.spam eggs
    '''
    return eggs

Now when the sys.doc call is executed the docstring will be cleanly returned to the calling terminal.

  Add Module metadata

Add information about the module using the following field lists:

:maintainer:    Thomas Hatch <thatch@saltstack.com, Seth House <shouse@saltstack.com>
:maturity:      new
:depends:       python-mysqldb
:platform:      all

The maintainer field is a comma-delimited list of developers who help maintain this module.

The maturity field indicates the level of quality and testing for this module. Standard labels will be determined.

The depends field is a comma-delimited list of modules that this module depends on.

The platform field is a comma-delimited list of platforms that this module is known to run on.

  How Functions are Read

In Salt, Python callable objects contained within a module are made available to the Salt minion for use. The only exception to this rule is a callable object with a name starting with an underscore _.

  Objects Loaded Into the Salt Minion

def foo(bar):
    return bar
class baz:
    def __init__(self, quo):
        pass

  Objects NOT Loaded into the Salt Minion

def _foobar(baz): # Preceded with an _
    return baz
cheese = {} # Not a callable Python object

  Examples of Salt Modules

The existing Salt modules should be fairly easy to read and understand, the goal of the main distribution's Salt modules is not only to build a set of functions for Salt, but to stand as examples for building out more Salt modules.

The existing modules can be found here: https://github.com/saltstack/salt/blob/develop/salt/modules

The most simple module is the test module, it contains the simplest Salt function, test.ping:

def ping():
    '''
    Just used to make sure the minion is up and responding
    Return True
    CLI Example::
        salt '*' test.ping
    '''
    return True

    salt '*' pillar.get pkg:apache

salt.modules.config.is_true(value=None)
    Returns a boolean value representing the "truth" of the value passed. The rules for what is a True value are:

1.  Numeric values greater than 0

2.  The string values True and true

3.  Any object for which bool(obj) returns True

    CLI Example:

    salt '*' config.is_true true

salt.modules.config.manage_mode(mode)
    Return a mode value, normalized to a string

    CLI Example:

    salt '*' config.manage_mode

    CLI Example:

    salt '*' config.option redis.host

salt.modules.config.valid_fileproto(uri)
    Returns a boolean value based on whether or not the URI passed has a valid remote file protocol designation

    CLI Example:

    salt '*' config.valid_fileproto salt://path/to/file

  salt.modules.cp

Minion side functions for salt-cp

salt.modules.cp.cache_dir(path, env='base', include_empty=False)
    Download and cache everything under a directory from the master

    CLI Example:

    salt '*' cp.cache_dir salt://path/to/dir

salt.modules.cp.cache_file(path, env='base')
    Used to cache a single file in the local salt-master file cache.

    CLI Example:

    salt '*' cp.cache_file salt://path/to/file

salt.modules.cp.cache_files(paths, env='base')
    Used to gather many files from the master, the gathered files will be saved in the minion cachedir reflective to the paths retrieved from the master.

    CLI Example:

    salt '*' cp.cache_files salt://pathto/file1,salt://pathto/file1

salt.modules.cp.cache_local_file(path)
    Cache a local file on the minion in the localfiles cache

    CLI Example:

    salt '*' cp.cache_local_file /etc/hosts

salt.modules.cp.cache_master(env='base')
    Retrieve all of the files on the master and cache them locally

    CLI Example:

    salt '*' cp.cache_master

salt.modules.cp.get_dir(path, dest, env='base', template=None, gzip=None)
    Used to recursively copy a directory from the salt master

    CLI Example:

    salt '*' cp.get_dir salt://path/to/dir/ /minion/dest

    get_dir supports the same template and gzip arguments as get_file.

salt.modules.cp.get_file(path, dest, env='base', makedirs=False, template=None, gzip=None)
    Used to get a single file from the salt master

    CLI Example:

    salt '*' cp.get_file salt://path/to/file /minion/dest

    Template rendering can be enabled on both the source and destination file names like so:

    salt '*' cp.get_file "salt://{{grains.os}}/vimrc" /etc/vimrc template=jinja

    This example would instruct all Salt minions to download the vimrc from a directory with the same name as their os grain and copy it to /etc/vimrc

    For larger files, the cp.get_file module also supports gzip compression. Because gzip is CPU-intensive, this should only be used in scenarios where the compression ratio is very high (e.g. pretty-printed JSON or YAML files).

    Use the gzip named argument to enable it. Valid values are 1..9, where 1 is the lightest compression and 9 the heaviest. 1 uses the least CPU on the master (and minion), 9 uses the most.

    CLI Example:

    salt '*' cp.hash_file salt://path/to/file

salt.modules.cp.is_cached(path, env='base')

Manage information about files on the minion, set/read user, group, and mode data

salt.modules.file.append(path, *args)
    Append text to the end of a file

    CLI Example:

    salt '*' file.append /etc/motd \
            "With all thine offerings thou shalt offer salt."\
            "Salt is what makes things taste bad when it isn't in them."

    New in version 0.9.5.

salt.modules.file.check_file_meta(name, sfn, source, source_sum, user, group, mode, env, template=None)
    Check for the changes in the file metadata.

    CLI Example:

    salt '*' file.check_file_meta /etc/httpd/conf.d/httpd.conf salt://http/httpd.conf '{hash_type: 'md5', 'hsum': <md5sum>}' root, root, '755' base

salt.modules.file.check_hash(path, hash)
    Check if a file matches the given hash string

    Returns true if the hash matched, otherwise false. Raises ValueError if the hash was not formatted correctly.

path
    A file path

hash
    A string in the form <hash_type>=<hash_value>. For example: md5=e138491e9d5b97023cea823fe17bac22

    CLI Example:

    salt '*' file.check_hash /etc/fstab md5=<md5sum>

salt.modules.file.check_managed(name, source, source_hash, user, group, mode, template, makedirs, context, defaults, env, **kwargs)
    Check to see what changes need to be made for a file

    CLI Example:

    salt '*' file.check_managed /etc/httpd/conf.d/httpd.conf salt://http/httpd.conf '{hash_type: 'md5', 'hsum': <md5sum>}' root, root, '755' jinja True None None base

salt.modules.file.check_perms(name, ret, user, group, mode)
    Check the permissions on files and chown if needed

Note: 'mode' here is expected to be either a string or an integer,
    in which case it will be converted into a base-10 string.

    What this means is that in your YAML salt file, you can specify mode as an integer(eg, 644) or as a string(eg, '644'). But, to specify mode 0777, for example, it must be specified as the string, '0777' otherwise, 0777 will be parsed as an octal and you'd get 511 instead.

    CLI Example:

    salt '*' file.check_perms /etc/sudoers '{}' root root 400

salt.modules.file.chgrp(path, group)

    CLI Example:

    salt '*' file.chown /etc/passwd root root

salt.modules.file.comment(path, regex, char='#', backup='.bak')
    Comment out specified lines in a file

path
    The full path to the file to be edited

regex
    A regular expression used to find the lines that are to be commented; this pattern will be wrapped in parenthesis and will move any preceding/trailing ^ or $ characters outside the parenthesis (e.g., the pattern ^foo$ will be rewritten as ^(foo)$)

char
    # The character to be inserted at the beginning of a line in order to comment it out

backup
    .bak The file will be backed up before edit with this file extension

Warning
    This backup will be overwritten each time sed / comment / uncomment is called. Meaning the backup will only be useful after the first invocation.

CLI Example:

salt '*' file.comment /etc/modules pcspkr

New in version 0.9.5.

salt.modules.file.contains(path, text)
    Return True if the file at path contains text

  salt.modules.ldapmod

Module to provide LDAP commands via salt.

depends

•   ldap Python module

configuration
    In order to connect to LDAP, certain configuration is required in the minion config on the LDAP server. The minimum configuration items that must be set are:

    ldap.basedn: dc=acme,dc=com (example values, adjust to suit)

    If your LDAP server requires authentication then you must also set:

    ldap.binddn: admin
    ldap.bindpw: password

    In addition, the following optional values may be set:

    ldap.server: localhost (default=localhost, see warning below)
    ldap.port: 389 (default=389, standard port)
    ldap.tls: False (default=False, no TLS)
    ldap.scope: 2 (default=2, ldap.SCOPE_SUBTREE)
    ldap.attrs: [saltAttr] (default=None, return all attributes)

Warning
    At the moment this module only recommends connection to LDAP services listening on 'localhost'. This is deliberate to avoid the potentially dangerous situation of multiple minions sending identical update commands to the same LDAP server. It's easy enough to override this behaviour, but badness may ensue - you have been warned.

salt.modules.ldapmod.search(filter, dn=None, scope=None, attrs=None, **kwargs)

                 'saltState': ['foo', 'bar']}]],
            'time': {'human': '1.2ms', 'raw': '0.00123'}}}

    Search and connection options can be overridden by specifying the relevant option as key=value pairs, for example:

    salt 'ldaphost' ldap.search filter=cn=myhost dn=ou=hosts,o=acme,c=gb
    scope=1 attrs='' server='localhost' port='7393' tls=True bindpw='ssh'

    {'<package>': {'old': '<old-version>',
                   'new': '<new-version>'}}

    CLI Example, installing a datastream pkg that already exists on the minion:

    salt '*' pkg.install sources='[{"<pkg name>": "/dir/on/minion/<pkg filename>"}]'
    salt '*' pkg.install sources='[{"SMClgcc346": "/var/spool/pkg/gcc-3.4.6-sol10-sparc-local.pkg"}]'

    CLI Example, installing a datastream pkg that exists on the salt master:

    salt '*' pkg.install sources='[{"<pkg name>": "salt://pkgs/<pkg filename>"}]'
    salt '*' pkg.install sources='[{"SMClgcc346": "salt://pkgs/gcc-3.4.6-sol10-sparc-local.pkg"}]'

    CLI Example, installing a datastream pkg that exists on a HTTP server:

    salt '*' pkg.install sources='[{"<pkg name>": "http://packages.server.com/<pkg filename>"}]'
    salt '*' pkg.install sources='[{"SMClgcc346": "http://packages.server.com/gcc-3.4.6-sol10-sparc-local.pkg"}]'

    If working with solaris zones and you want to install a package only in the global zone you can pass 'current_zone_only=True' to salt to have the package only installed in the global zone. (Behind the scenes this is passing '-G' to the pkgadd command.) Solaris default when installing a package in the global zone is to install it in all zones. This overrides that and installs the package only in the global.

    CLI Example, installing a datastream package only in the global zone:

    salt 'global_zone' pkg.install sources='[{"SMClgcc346": "/var/spool/pkg/gcc-3.4.6-sol10-sparc-local.pkg"}]' current_zone_only=True

    By default salt automatically provides an adminfile, to automate package installation, with these options set: email= instance=quit partial=nocheck runlevel=nocheck idepend=nocheck rdepend=nocheck space=nocheck setuid=nocheck conflict=nocheck action=nocheck basedir=default

    You can override any of these options in two ways. First you can optionally pass any of the options as a kwarg to the module/state to override the default value or you can optionally pass the 'admin_source' option providing your own adminfile to the minions.

    Note: You can find all of the possible options to provide to the adminfile by reading the admin man page:

    man -s 4 admin

    CLI Example - Overriding the 'instance' adminfile option when calling the module directly:

    salt '*' pkg.install sources='[{"<pkg name>": "salt://pkgs/<pkg filename>"}]' instance="overwrite"

    CLI Example - Overriding the 'instance' adminfile option when used in a state:

    SMClgcc346:
      pkg.installed:
        - sources:
          - SMClgcc346: salt://srv/salt/pkgs/gcc-3.4.6-sol10-sparc-local.pkg
        - instance: overwrite

    Note: the ID declaration is ignored, as the package name is read from the "sources" parameter.

    CLI Example - Providing your own adminfile when calling the module directly:

    salt '*' pkg.install sources='[{"<pkg name>": "salt://pkgs/<pkg filename>"}]' admin_source='salt://pkgs/<adminfile filename>'

    CLI Example - Providing your own adminfile when using states:

    <pkg name>:
      pkg.installed:
        - sources:
          - <pkg name>: salt://pkgs/<pkg filename>
        - admin_source: salt://pkgs/<adminfile filename>

    Note: the ID declaration is ignored, as the package name is read from the "sources" parameter.

    NOTE: As package repositories are not presently supported for Solaris pkgadd, this function will always return an empty string for a given package.

salt.modules.solarispkg.list_pkgs(versions_as_list=False)
    List the packages currently installed as a dict:

    {'<package_name>': '<version>'}

    Returns a list containing the removed packages.

    CLI Example:

    salt '*' pkg.purge <package name>

salt.modules.solarispkg.remove(name, **kwargs)
    Remove a single package with pkgrm

    By default salt automatically provides an adminfile, to automate package removal, with these options set:

    idepend=nocheck
    rdepend=nocheck
    space=nocheck
    setuid=nocheck
    conflict=nocheck
    action=nocheck
    basedir=default

    You can override any of these options in two ways. First you can optionally pass any of the options as a kwarg to the module/state to override the default value or you can optionally pass the 'admin_source' option providing your own adminfile to the minions.

    Note: You can find all of the possible options to provide to the adminfile by reading the admin man page:

    man -s 4 admin

    CLI Example:

    salt '*' pkg.remove <package name>
    salt '*' pkg.remove SUNWgit

  salt.modules.solr

  Apache Solr Salt Module

Author: Jed Glazner Version: 0.2.1 Modified: 12/09/2011

This module uses http requests to talk to the apache solr request handlers to gather information and report errors. Because of this the minion doesn't necessarily need to reside on the actual slave. However if you want to use the signal function the minion must reside on the physical solr host.

This module supports multi-core and standard setups. Certain methods are master/slave specific. Make sure you set the solr.type. If you have questions or want a feature request please ask.

  Coming Features in 0.3

1.  Add command for checking for replication failures on slaves

2.  Improve match_index_versions since it's pointless on busy solr masters

3.  Add additional local fs checks for backups to make sure they succeeded

  Override these in the minion config

solr.cores
    A list of core names eg ['core1','core2']. An empty list indicates non-multicore setup.

solr.baseurl
    The root level url to access solr via http

solr.request_timeout
    The number of seconds before timing out an http/https/ftp request. If nothing is specified then the python global timeout setting is used.

solr.type
    Possible values are 'master' or 'slave'

solr.backup_path
    The path to store your backups. If you are using cores and you can specify to append the core name to the path in the backup method.

solr.num_backups
    For versions of solr >= 3.5. Indicates the number of backups to keep. This option is ignored if your version is less.

solr.init_script
    The full path to your init script with start/stop options

solr.dih.options
    A list of options to pass to the dih.

  Required Options for DIH

clean
    False Clear the index before importing

commit
    True Commit the documents to the index upon completion

salt.modules.solr.optimize(host=None, core_name=None)
    Search queries fast, but it is a very expensive operation. The ideal process is to run this with a master/slave configuration. Then you can optimize the master, and push the optimized index to the slaves. If you are running a single solr instance, or if you are going to run this on a slave be aware than search performance will be horrible while this command is being run. Additionally it can take a LONG time to run and your http request may timeout. If that happens adjust your timeout settings.

    CLI Example:

    salt '*' solr.ping music

salt.modules.solr.reload_core(host=None, core_name=None)
    MULTI-CORE HOSTS ONLY Load a new core from the same configuration as an existing registered core. While the "new" core is initializing, the "old" one will continue to accept requests. Once it has finished, all new request will go to the "new" core, and the "old" core will be unloaded.

    {'success':boolean, 'data':dict, 'errors':list, 'warnings':list}

    CLI Example:

    salt '*' solr.replication_details music

    CLI Example:

    salt '*' solr.set_replication_enabled false, None, music

salt.modules.solr.signal(signal=None)
    Signals Apache Solr to start, stop, or restart. Obviously this is only going to work if the minion resides on the solr host. Additionally Solr doesn't ship with an init script so one must be created.

signal
    str (None) The command to pass to the apache solr init valid values are 'start', 'stop', and 'restart'

    CLI Example:

    salt '*' solr.signal restart

    status.cpustats.custom: [ 'cpu', 'ctxt', 'btime', 'processes' ]

    Where status refers to status.py, cpustats is the function where we get our data, and custom is this function It is followed by a list of keys that we want returned.

    This function is meant to replace all_status(), which returns anything and everything, which we probably don't want.

  salt.modules.tls

A salt module for SSL/TLS. Can create a Certificate Authority (CA) or use Self-Signed certificates.

depends

•   PyOpenSSL Python module

configuration
    Add the following values in /etc/salt/minion for the CA module to function properly:

    ca.cert_base_path: '/etc/pki'

salt.modules.tls.create_ca(ca_name, bits=2048, days=365, CN='localhost', C='US', ST='Utah', L='Salt Lake City', O='Salt Stack', OU=None, emailAddress='xyz@pdq.net')
    Create a Certificate Authority (CA)

ca_name
    name of the CA

bits
    number of RSA key bits, default is 2048

days
    number of days the CA will be valid, default is 365

CN  common name in the request, default is "localhost"

C   country, default is "US"

ST  state, default is "Utah"

L   locality, default is "Centerville", the city where SaltStack originated

O   organization, default is "Salt Stack"

OU  organizational unit, default is None

emailAddress
    email address for the CA owner, default is 'xyz@pdq.net'

    Writes out a CA certificate based upon defined config values. If the file already exists, the function just returns assuming the CA certificate already exists.

    If the following values were set:

    ca.cert_base_path='/etc/pki/koji' ca_name='koji'

    the resulting CA would be written in the following location:

    /etc/pki/koji/koji_ca_cert.crt

    CLI Example:

    salt '*' tls.create_ca test_ca

salt.modules.tls.create_ca_signed_cert(ca_name, CN, days=365)
    Create a Certificate (CERT) signed by a named Certificate Authority (CA)

ca_name
    name of the CA

CN  common name matching the certificate signing request

days
    number of days certficate is valid, default is 365 (1 year)

    Writes out a Certificate (CERT) If the file already exists, the function just returns assuming the CERT already exists.

    The CN must match an existing CSR generated by create_csr. If it does not, this method does nothing.

    CLI Example:

    salt '*' tls.create_ca_signed_cert test localhost

salt.modules.tls.create_csr(ca_name, bits=2048, CN='localhost', C='US', ST='Utah', L='Salt Lake City', O='Salt Stack', OU=None, emailAddress='xyz@pdq.net')
    Create a Certificate Signing Request (CSR) for a particular Certificate Authority (CA)

ca_name
    name of the CA

bits
    number of RSA key bits, default is 2048

CN  common name in the request, default is "localhost"

C   country, default is "US"

ST  state, default is "Utah"

L   locality, default is "Centerville", the city where SaltStack originated

O   organization, default is "Salt Stack" NOTE: Must the same as CA certificate or an error will be raised

OU  organizational unit, default is None

emailAddress
    email address for the request, default is 'xyz@pdq.net'

    Writes out a Certificate Signing Request (CSR) If the file already exists, the function just returns assuming the CSR already exists.

    If the following values were set:

    ca.cert_base_path='/etc/pki/koji' ca_name='koji' CN='test.egavas.org'

    the resulting CSR, and corresponding key, would be written in the following location:

    /etc/pki/koji/certs/test.egavas.org.csr /etc/pki/koji/certs/test.egavas.org.key

    CLI Example:

    salt '*' tls.create_csr test

    Create a PKCS#12 browser certificate for a particular Certificate (CN)

ca_name
    name of the CA

CN  common name matching the the certificate signing request

passphrase
    used to unlock the PKCS#12 certificate when loaded into the browser

    CLI Example:

    salt '*' tls.create_pkcs12 test localhost

salt.modules.tls.create_self_signed_cert(tls_dir='tls', bits=2048, days=365, CN='localhost', C='US', ST='Utah', L='Salt Lake City', O='Salt Stack', OU=None, emailAddress='xyz@pdq.net')
    Create a Self-Signed Certificate (CERT)

tls_dir
    location appended to the ca.cert_base_path, default is 'tls'

bits
    number of RSA key bits, default is 2048

CN  common name in the request, default is "localhost"

C   country, default is "US"

ST  state, default is "Utah"

L   locality, default is "Centerville", the city where SaltStack originated

O   organization, default is "Salt Stack" NOTE: Must the same as CA certificate or an error will be raised

OU  organizational unit, default is None

emailAddress
    email address for the request, default is 'xyz@pdq.net'

    Writes out a Self-Signed Certificate (CERT). If the file already exists, the function just returns.

    If the following values were set:

    ca.cert_base_path='/etc/pki/koji' tls_dir='koji' CN='test.egavas.org'

    the resulting CERT, and corresponding key, would be written in the following location:

    /etc/pki/tls/certs/test.egavas.org.crt /etc/pki/tls/certs/test.egavas.org.key

    CLI Example:

    salt '*' tls.create_self_signed_cert

  salt.modules.tomcat

Support for Tomcat

This module uses the manager webapp to manage Apache tomcat webapps If the manager webapp is not configured some of the functions won't work

The following grains should be set tomcat-manager: user: admin user name passwd: password

or use pillar: tomcat-manager.user: admin user name tomcat-manager.passwd: password

and also configure a user in the conf/tomcat-users.xml file: <?xml version='1.0' encoding='utf-8'?> <tomcat-users> <role rolename="manager-script"/> <user username="tomcat" password="tomcat" roles="manager-script"/>

</tomcat-users>

Notes: - More information about tomcat manager: http://tomcat.apache.org/tomcat-7.0-doc/manager-howto.html - if you use only this module for deployments you've might want to strict access to the manager only from localhost for more info: http://tomcat.apache.org/tomcat-7.0-doc/manager-howto.html#Configuring_Manager_Application_Access

  salt.modules.upstart

Module for the management of upstart systems. The Upstart system only supports service starting, stopping and restarting.

Currently (as of Ubuntu 12.04) there is no tool available to disable Upstart services (like update-rc.d). This[1] is the recommended way to disable an Upstart service. So we assume that all Upstart services that have not been disabled in this manner are enabled.

But this is broken because we do not check to see that the dependent services are enabled. Otherwise we would have to do something like parse the output of "initctl show-config" to determine if all service dependencies are enabled to start on boot. For example, see the "start on" condition for the lightdm service below[2]. And this would be too hard. So we wait until the upstart developers have solved this problem. :) This is to say that an Upstart service that is enabled may not really be enabled.

Also, when an Upstart service is enabled, should the dependent services be enabled too? Probably not. But there should be a notice about this, at least.

RETURNERS

By default the return values of the commands sent to the Salt minions are returned to the salt-master. But since the commands executed on the Salt minions are detached from the call on the Salt master, there is no need for the minion to return the data to the Salt master.

This is where the returner interface comes in. Returners are modules called in place of returning the data to the Salt master.

The returner interface allows the return data to be sent to any system that can receive data. This means that return data can be sent to a Redis server, a MongoDB server, a MySQL server, or any system!

See also

    Full list of builtin returners

  Using Returners

All commands will return the command data back to the master. Adding more returners will ensure that the data is also sent to the specified returner interfaces.

Specifying what returners to use is done when the command is invoked:

salt '*' test.ping --return redis_return

This command will ensure that the redis_return returner is used.

It is also possible to specify multiple returners:

salt '*' test.ping --return mongo_return,redis_return,cassandra_return

In this scenario all three returners will be called and the data from the test.ping command will be sent out to the three named returners.

  Writing a Returner

A returner is a module which contains a returner function, the returner function must accept a single argument. this argument is the return data from the called minion function. So if the minion function test.ping is called the value of the argument will be True.

A simple returner is implemented here:

import redis
import json
def returner(ret):
    '''
    Return information to a redis server
    '''
    # Get a redis connection
    serv = redis.Redis(
                host='redis-serv.example.com',
                port=6379,
                db='0')
    serv.sadd("%(id)s:jobs" % ret, ret['jid'])
    serv.set("%(jid)s:%(id)s" % ret, json.dumps(ret['return']))
    serv.sadd('jobs', ret['jid'])
    serv.sadd(ret['jid'], ret['id'])

This simple example of a returner set to send the data to a redis server serializes the data as json and sets it in redis.

You can place your custom returners in a _returners directory within the file_roots specified by the master config file. These custom returners are distributed when state.highstate is run, or by executing the saltutil.sync_returners or saltutil.sync_all functions.

There are a few things to keep in mind:

•   If a username is used, a password is also required.

•   You should at least declare a subject, but you don't have to.

•   smtp.fields lets you include the value(s) of various fields in the subject line of the email. These are comma-delimited. For instance: smtp.fields: id,fun

    subject line. You may also use 'jid' (the job id), but it is generally recommended not to use 'return', which contains the entire return data structure (which can be very large).

salt.returners.syslog_return.returner(ret)
    Return data to the local syslog

STATE FILE BACKUPS

In 0.10.2 a new feature was added for backing up files that are replaced by the file.managed and file.recurse states. The new feature is called the backup mode. Setting the backup mode is easy, but is can be set in a number of places.

The backup_mode can be set in the minion config file:

backup_mode: minion

Or it can be set for each file:

/etc/ssh/sshd_config:
  file.managed:
    - source: salt://ssh/sshd_config
    - backup: minion

  Backed up Files

The files will be saved in the minion cachedir under the directory named file_backup. The files will be in the location relative to where they were under the root filesystem and be appended with a timestamp. This should make them easy to browse.

EXTENDING EXTERNAL SLS DATA

Sometimes a state defined in one SLS file will need to be modified from a separate SLS file. A good example of this is when an argument needs to be overwritten or when a service needs to watch an additional state.

  The Extend Declaration

The standard way to extend is via the extend declaration. The extend declaration is a top level declaration like include and encapsulates ID declaration data included from other SLS files. A standard extend looks like this:

include:
  - http
  - ssh
extend:
  apache:
    file:
      - name: /etc/httpd/conf/httpd.conf
      - source: salt://http/httpd2.conf
  ssh-server:
    service:
      - watch:
        - file: /etc/ssh/banner
/etc/ssh/banner:
  file.managed:
    - source: salt://ssh/banner

A few critical things happened here, first off the SLS files that are going to be extended are included, then the extend dec is defined. Under the extend dec 2 IDs are extended, the apache ID's file state is overwritten with a new name and source. Than the ssh server is extended to watch the banner file in addition to anything it is already watching.

  Extend is a Top Level Declaration

This means that extend can only be called once in an sls, if if is used twice then only one of the extend blocks will be read. So this is WRONG:

include:
  - http
  - ssh
extend:
  apache:
    file:
      - name: /etc/httpd/conf/httpd.conf
      - source: salt://http/httpd2.conf
# Second extend will overwrite the first!! Only make one
extend:
  ssh-server:
    service:
      - watch:
        - file: /etc/ssh/banner

  The Requisite in Statement

Since one of the most common things to do when extending another SLS is to add states for a service to watch, or anything for a watcher to watch, the requisite in statement was added to 0.9.8 to make extending the watch and require lists easier. The ssh-server extend statement above could be more cleanly defined like so:

include:
  - ssh
/etc/ssh/banner:
  file.managed:
    - source: salt://ssh/banner
    - watch_in:
      - service: ssh-server

  Rules to Extend By

There are a few rules to remember when extending states:

1.  Always include the SLS being extended with an include declaration

2.  Requisites (watch and require) are appended to, everything else is overwritten

3.  extend is a top level declaration, like an ID declaration, cannot be declared twice in a single SLS

4.  Many IDs can be extended under the extend declaration

FAILHARD GLOBAL OPTION

Normally, when a state fails Salt continues to execute the remainder of the defined states and will only refuse to execute states that require the failed state.

But the situation may exist, where you would want all state execution to stop if a single state execution fails. The capability to do this is called failing hard.

  State Level Failhard

A single state can have a failhard set, this means that if this individual state fails that all state execution will immediately stop. This is a great thing to do if there is a state that sets up a critical config file and setting a require for each state that reads the config would be cumbersome. A good example of this would be setting up a package manager early on:

/etc/yum.repos.d/company.repo:
  file.managed:
    - source: salt://company/yumrepo.conf
    - user: root
    - group: root
    - mode: 644
    - order: 1
    - failhard: True

In this situation, the yum repo is going to be configured before other states, and if it fails to lay down the config file, than no other states will be executed.

  Global Failhard

It may be desired to have failhard be applied to every state that is executed, if this is the case, then failhard can be set in the master configuration file. Setting failhard in the master configuration file will result in failing hard when any minion gathering states from the master have a state fail.

This is NOT the default behavior, normally Salt will only fail states that require a failed state.

Using the global failhard is generally not recommended, since it can result in states not being executed or even checked. It can also be confusing to see states failhard if an admin is not actively aware that the failhard has been set.

To use the global failhard set failhard: True in the master configuration file.

HIGHSTATE DATA STRUCTURE DEFINITIONS

  The Salt State Tree

Top file
    The main state file that instructs minions what environment and modules to use during state execution.

    Configurable via state_top.

See also

    A detailed description of the top file

State tree
    A collection of SLS files that live under the directory specified in file_roots. A state tree can be organized into SLS modules.

  Include declaration

Include declaration
    Defines a list of module reference strings to include in this SLS.

    Occurs only in the top level of the highstate structure.

    Example:

    include:
      - edit.vim
      - http.server

  Module reference

Module reference
    The name of a SLS module defined by a separate SLS file and residing on the Salt Master. A module named edit.vim is a reference to the SLS file salt://edit/vim.sls.

  ID declaration

ID declaration
    Defines an individual highstate component. Always references a value of a dictionary containing keys referencing state declarations and requisite declarations. Can be overridden by a name declaration or a names declaration.

    Occurs on the top level or under the extend declaration.

    Must be unique across entire state tree. If the same ID declaration is used twice, only the first one matched will be used. All subsequent ID declarations with the same name will be ignored.

Note
    Naming gotchas

    Until 0.9.6, IDs could not contain a dot, otherwise highstate summary output was unpredictable. (It was fixed in versions 0.9.7 and above)

  Extend declaration

Extend declaration
    Extends a name declaration from an included SLS module. The keys of the extend declaration always define existing ID declarations which have been defined in included SLS modules.

    Occurs only in the top level and defines a dictionary.

    Extend declarations are useful for adding-to or overriding parts of a state declaration that is defined in another SLS file. In the following contrived example, the shown mywebsite.sls file is include -ing and extend -ing the apache.sls module in order to add a watch declaration that will restart Apache whenever the Apache configuration file, mywebsite changes.

    include:
      - apache
    extend:
      apache:
        service:
          - watch:
            - file: mywebsite
    mywebsite:
      file:
        - managed
    .. seealso:: watch_in and require_in
        Sometimes it is more convenient to use the :term:`watch_in` or
        :term:`require_in` syntax instead of extending another ``SLS``
        file.

  State declaration

State declaration
    A list which contains one string defining the function declaration and any number of function arg declaration dictionaries.

    Can, optionally, contain a number of additional components like the name override components — name and names. Can also contain requisite declarations.

    Occurs under an ID declaration.

  Requisite declaration

Requisite declaration
    A list containing requisite references.

    Used to build the action dependency tree. While Salt states are made to execute in a deterministic order, this order is managed by requiring and watching other Salt states.

    Occurs as a list component under a state declaration or as a key under an ID declaration.

  Requisite reference

Requisite reference
    A single key dictionary. The key is the name of the referenced state declaration and the value is the ID of the referenced ID declaration.

    Occurs as a single index in a requisite declaration list.

  Function declaration

Function declaration
    The name of the function to call within the state. A state declaration can contain only a single function declaration.

    For example, the following state declaration calls the installed function in the pkg state module:

    httpd:
      pkg.installed

    The function can be declared inline with the state as a shortcut, but the actual data structure is better referenced in this form:

    httpd:
      pkg:
        - installed

    Where the function is a string in the body of the state declaration. Technically when the function is declared in dot notation the compiler converts it to be a string in the state declaration list. Note that the use of the first example more than once in an ID declaration is invalid yaml.

    INVALID:

    httpd:
      pkg.installed
      service.running

    When passing a function without arguments and another state declaration within a single ID declaration, then the long or "standard" format needs to be used since otherwise it does not represent a valid data structure.

    VALID:

    httpd:
      pkg:
        - installed
      service:
        - running

    Occurs as the only index in the state declaration list.

  Function arg declaration

Function arg declaration
    A single key dictionary referencing a Python type which is to be passed to the named function declaration as a parameter. The type must be the data type expected by the function.

    Occurs under a function declaration.

    For example in the following state declaration user, group, and mode are passed as arguments to the managed function in the file state module:

    /etc/http/conf/http.conf:
      file.managed:
        - user: root
        - group: root
        - mode: 644

  Name declaration

Name declaration
    Overrides the name argument of a state declaration. If name is not specified the ID declaration satisfies the name argument.

    The name is always a single key dictionary referencing a string.

    Overriding name is useful for a variety of scenarios.

    For example, avoiding clashing ID declarations. The following two state declarations cannot both have /etc/motd as the ID declaration:

    motd_perms:
      file.managed:
        - name: /etc/motd
        - mode: 644
    motd_quote:
      file.append:
        - name: /etc/motd
        - text: "Of all smells, bread; of all tastes, salt."

    Another common reason to override name is if the ID declaration is long and needs to be referenced in multiple places. In the example below it is much easier to specify mywebsite than to specify /etc/apache2/sites-available/mywebsite.com multiple times:

    mywebsite:
      file.managed:
        - name: /etc/apache2/sites-available/mywebsite.com
        - source: salt://mywebsite.com
    a2ensite mywebsite.com:
      cmd.wait:
        - unless: test -L /etc/apache2/sites-enabled/mywebsite.com
        - watch:
          - file: mywebsite
    apache2:
      service:
        - running
        - watch:
          - file: mywebsite

  Names declaration

Names declaration
    Expands the contents of the containing state declaration into multiple state declarations, each with its own name.

    For example, given the following state declaration:

    python-pkgs:
      pkg.installed:
        - names:
          - python-django
          - python-crypto
          - python-yaml

    Once converted into the lowstate data structure the above state declaration will be expanded into the following three state declarations:

    python-django:
      pkg.installed
    python-crypto:
      pkg.installed
    python-yaml:
      pkg.installed

INCLUDE AND EXCLUDE

Salt sls files can include other sls files and exclude sls files that have been otherwise included. This allows for an sls file to easily extend or manipulate other sls files.

  Exclude

The exclude statement, added in Salt 0.10.3 allows an sls to hard exclude another sls file or a specific id. The component is excluded after the high data has been compiled, so nothing should be able to override an exclude.

Since the exclude can remove an id or an sls the type of component to exclude needs to be defined. an exclude statement that verifies that the running highstate does not contain the http sls and the /etc/vimrc id would look like this:

exclude:
  - sls: http
  - id: /etc/vimrc

STATE ENFORCEMENT

Salt offers an optional interface to manage the configuration or "state" of the Salt minions. This interface is a fully capable mechanism used to enforce the state of systems from a central manager.

The Salt state system is made to be accurate, simple, and fast. And like the rest of the Salt system, Salt states are highly modular.

  State management

State management, also frequently called software configuration management (SCM), is a program that puts and keeps a system into a predetermined state. It installs software packages, starts or restarts services, or puts configuration files in place and watches them for changes.

Having a state management system in place allows you to easily and reliably configure and manage a few servers or a few thousand servers. It allows you to keep that configuration under version control.

Salt States is an extension of the Salt Modules that we discussed in the previous remote execution tutorial. Instead of calling one-off executions the state of a system can be easily defined and then enforced.

  Understanding the Salt State System Components

The Salt state system is comprised of a number of components. As a user, an understanding of the SLS and renderer systems are needed. But as a developer, an understanding of Salt states and how to write the states is needed as well.

  Salt SLS System

SLS The primary system used by the Salt state system is the SLS system. SLS stands for SaLt State.

    The Salt States are files which contain the information about how to configure Salt minions. The states are laid out in a directory tree and can be written in many different formats.

    The contents of the files and they way they are laid out is intended to be as simple as possible while allowing for maximum flexibility. The files are laid out in states and contains information about how the minion needs to be configured.

  SLS File Layout

SLS files are laid out in the Salt file server. A simple layout can look like this:

top.sls
ssh.sls
sshd_config
users/init.sls
users/admin.sls
salt/init.sls
salt/master.sls

This example shows the core concepts of file layout. The top file is a key component and is used with Salt matchers to match SLS states with minions. The .sls files are states. The rest of the files are seen by the Salt master as just files that can be downloaded.

The states are translated into dot notation, so the ssh.sls file is seen as the ssh state, the users/admin.sls file is seen as the users.admin states.

The init.sls files are translated to be the state name of the parent directory, so the salt/init.sls file translates to the Salt state.

The plain files are visible to the minions, as well as the state files. In Salt, everything is a file; there is no "magic translation" of files and file types. This means that a state file can be distributed to minions just like a plain text or binary file.

  SLS Files

The Salt state files are simple sets of data. Since the SLS files are just data they can be represented in a number of different ways. The default format is yaml generated from a Jinja template. This allows for the states files to have all the language constructs of Python and the simplicity of yaml. State files can then be complicated Jinja templates that translate down to yaml, or just plain and simple yaml files!

The State files are constructed data structures in a simple format. The format allows for many real activates to be expressed in very little text, while maintaining the utmost in readability and usability.

Here is an example of a Salt State:

vim:
  pkg:
    - installed
salt:
  pkg:
    - latest
  service.running:
    - require:
      - file: /etc/salt/minion
      - pkg: salt
    - names:
      - salt-master
      - salt-minion
    - watch:
      - file: /etc/salt/minion
/etc/salt/minion:
  file.managed:
    - source: salt://salt/minion
    - user: root
    - group: root
    - mode: 644
    - require:
      - pkg: salt

This short stanza will ensure that vim is installed, Salt is installed and up to date, the salt-master and salt-minion daemons are running and the Salt minion configuration file is in place. It will also ensure everything is deployed in the right order and that the Salt services are restarted when the watched file updated.

  The Top File

The top file is the mapping for the state system. The top file specifies which minions should have which modules applied and which environments they should draw the states from.

The top file works by specifying the environment, containing matchers with lists of Salt states sent to the matching minions:

base:
  '*':
    - salt
    - users
    - users.admin
  'saltmaster.*':
    - match: pcre
    - salt.master

This simple example uses the base environment, which is built into the default Salt setup, and then all minions will have the modules salt, users and users.admin since '*' will match all minions. Then the regular expression matcher will match all minions' with an id matching saltmaster.* and add the salt.master state.

  Renderer System

The Renderer system is a key component to the state system. SLS files are representations of Salt "high data" structures. All Salt cares about when reading an SLS file is the data structure that is produced from the file.

This allows Salt states to be represented by multiple types of files. The Renderer system can be used to allow different formats to be used for SLS files.

The available renderers can be found in the renderers directory in the Salt source code:

https://github.com/saltstack/salt/blob/develop/salt/renderers

By default SLS files are rendered using Jinja as a templating engine, and yaml as the serialization format. Since the rendering system can be extended simply by adding a new renderer to the renderers directory, it is possible that any structured file could be used to represent the SLS files.

In the future XML and raw Python will be added, as well as many other formats.

ORDERING STATES

When creating Salt SLS files, it is often important to ensure that they run in a specific order. While states will always execute in the same order, that order is not necessarily defined the way you want it.

A few tools exist in Salt to set up the correct state ordering. These tools consist of requisite declarations and order options.

Note
    Salt does not execute state declarations in the order they appear in the source.

  Requisite Statements

Note
    This document represents behavior exhibited by Salt requisites as of version 0.9.7 of Salt.

Often when setting up states any single action will require or depend on another action. Salt allows you to build relationships between states with requisite statements. A requisite statement ensure that the named state is evaluated before the state requiring it. There are two types of requisite statements in Salt, require and watch.

These requisite statements are applied to a specific state declaration:

httpd:
  pkg:
    - installed
  file.managed:
    - name: /etc/httpd/conf/httpd.conf
    - source: salt://httpd/httpd.conf
    - require:
      - pkg: httpd

In this example we use the require requisite to declare that the file /etc/httpd/conf/httpd.conf should only be set up if the pkg state executes successfully.

The requisite system works by finding the states that are required and executing them before the state that requires them. Then the required states can be evaluated to see if they have executed correctly.

Note
    Requisite matching

    Requisites match on both the ID Declaration and the name parameter. Therefore, if you are using the pkgs or sources argument to install a list of packages in a pkg state, it's important to note that you cannot have a requisite that matches on an individual package in the list.

  Multiple Requisites

The requisite statement is passed as a list, allowing for the easy addition of more requisites. Both requisite types can also be separately declared:

httpd:
  pkg:
    - installed
  service.running:
    - enable: True
    - watch:
      - file: /etc/httpd/conf/httpd.conf
    - require:
      - pkg: httpd
      - user: httpd
      - group: httpd
  file.managed:
    - name: /etc/httpd/conf/httpd.conf
    - source: salt://httpd/httpd.conf
    - require:
      - pkg: httpd
  user:
    - present
  group:
    - present

In this example the httpd service is only going to be started if the package, user, group and file are executed successfully.

  The Require Requisite

The foundation of the requisite system is the require requisite. The require requisite ensures that the required state(s) are executed before the requiring state. So, if a state is declared that sets down a vimrc, then it would be pertinent to make sure that the vimrc file would only be set down if the vim package has been installed:

vim:
  pkg:
    - installed
  file.managed:
    - source: salt://vim/vimrc
    - require:
      - pkg: vim

In this case, the vimrc file will only be applied by Salt if and after the vim package is installed.

  The Watch Requisite

The watch requisite is more advanced than the require requisite. The watch requisite executes the same logic as require (therefore if something is watched it does not need to also be required) with the addition of executing logic if the required states have changed in some way.

The watch requisite checks to see if the watched states have returned any changes. If the watched state returns changes, and the watched states execute successfully, then the watching state will execute a function that reacts to the changes in the watched states.

Perhaps an example can better explain the behavior:

redis:
  pkg:
    - latest
  file.managed:
    - source: salt://redis/redis.conf
    - name: /etc/redis.conf
    - require:
      - pkg: redis
  service.running:
    - enable: True
    - watch:
      - file: /etc/redis.conf
      - pkg: redis

In this example the redis service will only be started if the file /etc/redis.conf is applied, and the file is only applied if the package is installed. This is normal require behavior, but if the watched file changes, or the watched package is installed or upgraded, then the redis service is restarted.

  Watch and the mod_watch Function

The watch requisite is based on the mod_watch function. Python state modules can include a function called mod_watch which is then called if the watch call is invoked. When mod_watch is called depends on the execution of the watched state, which:

•   If no changes then just run the watching state itself as usual. mod_watch is not called. This behavior is same as using a require.

•   If changes then run the watching state AND if that changes nothing then react by calling mod_watch.

    When reacting, in the case of the service module the underlying service is restarted. In the case of the cmd state the command is executed.

    The mod_watch function for the service state looks like this:

    def mod_watch(name, sig=None, reload=False, full_restart=False):
        '''
        The service watcher, called to invoke the watch command.
        name
            The name of the init or rc script used to manage the service
        sig
            The string to search for when looking for the service process with ps
        '''
        if __salt__['service.status'](name, sig):
            if 'service.reload' in __salt__ and reload:
                restart_func = __salt__['service.reload']
            elif 'service.full_restart' in __salt__ and full_restart:
                restart_func = __salt__['service.full_restart']
            else:
                restart_func = __salt__['service.restart']
        else:
            restart_func = __salt__['service.start']
        result = restart_func(name)
        return {'name': name,
                'changes': {name: result},
                'result': result,
                'comment': 'Service restarted' if result else \
                           'Failed to restart the service'
               }

    The watch requisite only works if the state that is watching has a mod_watch function written. If watch is set on a state that does not have a mod_watch function (like pkg), then the listed states will behave only as if they were under a require statement.

    Also notice that a mod_watch may accept additional keyword arguments, which, in the sls file, will be taken from the same set of arguments specified for the state that includes the watch requisite. This means, for the earlier service.running example above, you can tell the service to reload instead of restart like this:

    redis:
      # ... other state declarations omitted ...
        service.running:
          - enable: True
          - reload: True
          - watch:
            - file: /etc/redis.conf
            - pkg: redis

  The Order Option

Before using the order option, remember that the majority of state ordering should be done with a requisite declaration, and that a requisite declaration will override an order option.

The order option is used by adding an order number to a state declaration with the option order:

vim:
  pkg.installed:
    - order: 1

By adding the order option to 1 this ensures that the vim package will be installed in tandem with any other state declaration set to the order 1.

Any state declared without an order option will be executed after all states with order options are executed.

But this construct can only handle ordering states from the beginning. Sometimes you may want to send a state to the end of the line. To do this, set the order to last:

vim:
  pkg.installed:
    - order: last

Remember that requisite statements override the order option. So the order option should be applied to the highest component of the requisite chain:

vim:
  pkg.installed:
    - order: last
    - require:
      - file: /etc/vimrc
/etc/vimrc:
  file.managed:
    - source: salt://edit/vimrc

OVERSTATE SYSTEM

Often servers need to be set up and configured in a specific order, and systems should only be set up if systems earlier in the sequence has been set up without any issues.

The 0.11.0 release of Salt addresses this problem with a new layer in the state system called the Over State. The concept of the Over State is managed on the master, a series of state executions is controlled from the master and executed in order. If an execution requires that another execution first run without problems then the state executions will stop.

The Over State system is used to orchestrate deployment in a smooth and reliable way across multiple systems in small to large environments.

  The Over State SLS

The overstate system is managed by an sls file located in the root of an environment. This file uses a data structure like all sls files.

The overstate sls file configures an unordered list of stages, each stage defines the minions to execute on and can define what sls files to run or to execute a state.highstate.

mysql:
  match: db*
  sls:
    - mysql.server
    - drbd
webservers:
  match: web*
  require:
    - mysql
all:
  match: '*'
  require:
    - mysql
    - webservers

The above defined over state will execute the mysql stage first because it is required by the webservers stage. The webservers stage will then be executed only if the mysql stage executes without any issues. The webservers stage will execute state.highstate on the matched minions, while the mysql stage will execute state.sls with the named sls files.

Finally the all stage will execute state.highstate on all systems only if the mysql and webservers stages complete without failures. The overstate system checks for any states that return a result of False, if the run has any False returns then the overstate will quit.

  Executing the Over State

The over state can be executed from the salt-run command, calling the state.over runner function. The function will by default look in the base environment for the overstate.sls file:

salt-run state.over

To specify the location of the overstate file and the environment to pull from pass the arguments to the salt-run command:

salt-run state.over base /root/overstate.sls

Remember, that these calls are made on the master.

STATE PROVIDERS

New in version 0.9.8.

Salt predetermines what modules should be mapped to what uses based on the properties of a system. These determinations are generally made for modules that provide things like package and service management.

Sometimes in states, it may be necessary to use an alternative module to provide the needed functionality. For instance, an older Arch Linux system may not be running systemd, so instead of using the systemd service module, you can revert to the default service module:

httpd:
  service.running:
    - enable: True
    - provider: service

In this instance, the basic service module will replace the systemd module which is used by default on Arch Linux, and the httpd service will be managed using sysvinit.

Note
    You can also set a provider globally in the minion config providers.

  Arbitrary Module Redirects

The provider statement can also be used for more powerful means, instead of overwriting or extending the module used for the named service an arbitrary module can be used to provide certain functionality.

emacs:
  pkg.installed:
    - provider:
      - pkg: yumpkg5
      - cmd: customcmd

In this example the default pkg module is being redirected to use the yumpkg5 module (yum via shelling out instead of via the yum Python API), but is also using a custom module to invoke commands. This could be used to dramatically change the behavior of a given state.

REQUISITES

The Salt requisite system is used to create relationships between states. The core idea being, that when one state it dependent somehow on another that inter-dependency can be easily defined.

Requisites come in two types. Direct requisites, and requisite_ins. The relationships are directional, so a requisite statement makes the requiring state declaration depend on the required state declaration:

vim:
  pkg.installed
/etc/vimrc:
  file.managed:
    - source: salt://edit/vimrc
    - require:
      - pkg: vim

So in this example, the file /etc/vimrc depends on the vim package.

Requisite_in statements are the opposite, instead of saying "I depend on something", requisite_ins say "Someone depends on me":

vim:
  pkg.installed:
    - require_in:
      - file: /etc/vimrc
/etc/vimrc:
  file.managed:
    - source: salt://edit/vimrc

So here, with a requisite_in, the same thing is accomplished, but just from the other way around. The vim package is saying "/etc/vimrc depends on me".

In the end a single dependency map is created and everything is executed in a finite and predictable order.

Note
    Requisite matching

    Requisites match on both the ID Declaration and the name parameter. This means that in the example above, the require_in requisite would also have been matched if the /etc/vimrc state was written as follows:

    vimrc:
      file.managed:
        - name: /etc/vimrc
        - source: salt://edit/vimrc

  Requisite and Requisite in types

There are three requisite statements that can be used in Salt. the require, watch and use requisites. Each requisite also has a corresponding requisite_in: require_in, watch_in and use_in. All of the requisites define specific relationships and always work with the dependency logic defined above.

  Require

The most basic requisite statement is require. The behavior of require is simple. Make sure that the dependent state is executed before the depending state, and it the dependent state fails, don't run the depending state. So in the above examples the file /etc/vimrc will only be applied after the vim package is installed and only if the vim package is installed successfully.

  Watch

The watch statement does everything the require statement does, but with a little more. The watch statement looks into the state modules for a function called mod_watch. If this function is not available in the corresponding state module, then watch does the same thing as require. If the mod_watch function is in the state module, then the watched state is checked to see if it made any changes to the system, if it has, then mod_watch is called.

Perhaps the best example of using watch is with a service, when a service watches other states, then when the other states make changes on the system the service is reloaded or restarted.

  Use

The use requisite is used to inherit the arguments passed in another id declaration. This is useful when many files need to have the same defaults.

The use statement was developed primarily for the networking states but can be used on any states in Salt. This made sense for the networking state because it can define a long list of options that need to be applied to multiple network interfaces.

  Require In

The require_in requisite is the literal reverse of require. If a state declaration needs to be required by another state declaration then require_in can accommodate it, so these two sls files would be the same in the end:

Using require

httpd:
  pkg:
    - installed
  service:
    - running
    - require:
      - pkg: httpd

Using require_in

httpd:
  pkg:
    - installed
    - require_in:
      - service: httpd
  service:
    - running

The require_in statement is particularly useful when assigning a require in a separate sls file. For instance it may be common for httpd to require components used to set up PHP or mod_python, but the HTTP state does not need to be aware of the additional components that require it when it is set up:

http.sls

httpd:
  pkg:
    - installed
  service:
    - running
    - require:
      - pkg: httpd

php.sls

include:
  - http
php:
  pkg:
    - installed
    - require_in:
      - service: httpd

mod_python.sls

include:
  - http
mod_python:
  pkg:
    - installed
    - require_in:
      - service: httpd

Now the httpd server will only start if php or mod_python are first verified to be installed. Thus allowing for a requisite to be defined "after the fact".

  Watch In

Watch in functions the same was as require in, but applies a watch statement rather than a require statement to the external state declaration.

STARTUP STATES

Sometimes it may be desired that the salt minion execute a state run when it is started. This alleviates the need for the master to initiate a state run on a new minion and can make provisioning much easier.

As of Salt 0.10.3 the minion config reads options that allow for states to be executed at startup. The options are startup_states, sls_list and top_file.

The startup_states option can be passed one of a number of arguments to define how to execute states. The available options are:

highstate
    Execute state.highstate

sls Read in the sls_list option and execute the named sls files

top Read in the top_file option and execute states based on that top file on the Salt Master

  Examples:

Execute state.highstate when starting the minion:

startup_states: highstate

Execute the sls files edit.vim and hyper:

startup_states: sls
sls_list:
  - edit.vim
  - hyper

STATE TESTING

Executing a Salt state run can potentially change many aspects of a system and it may be desirable to first see what a state run is going to change before applying the run.

Salt has a test interface to report on exactly what will be changed, this interface can be invoked on any of the major state run functions:

# salt \* state.highstate test=True
# salt \* state.sls test=True
# salt \* state.single test=True

The test run is mandated by adding the test=True option to the states. The return information will show states that will be applied in yellow and the result is reported as None.

  Default Test

If the value test is set to True in the minion configuration file then states will default to being executed in test mode. If this value is set then states can still be run by calling test=False:

# salt \* state.highstate test=False
# salt \* state.sls test=False
# salt \* state.single test=False

THE TOP FILE

The top file is used to map what SLS modules get loaded onto what minions via the state system. The top file creates a few general abstractions. First it maps what nodes should pull from which environments, next it defines which matches systems should draw from.

  Environments

Environment
    A configuration that allows conceptually organizing state tree directories. Environments can be made to be self-contained or state trees can be made to bleed through environments.

    The environments in the top file corresponds with the environments defined in the file_roots variable. In a simple, single environment setup you only have the base environment, and therefore only one state tree. Here is a simple example of file_roots in the master configuration:

    file_roots:
      base:
        - /srv/salt

    This means that the top file will only have one environment to pull from, here is a simple, single environment top file:

    base:
      '*':
        - core
        - edit

    This also means that /srv/salt has a state tree. But if you want to use multiple environments, or partition the file server to serve more than just the state tree, then the file_roots option can be expanded:

    file_roots:
      base:
        - /srv/salt/base
      dev:
        - /srv/salt/dev
      qa:
        - /srv/salt/qa
      prod:
        - /srv/salt/prod

    Then our top file could reference the environments:

    dev:
      'webserver*dev*':
        - webserver
      'db*dev*':
        - db
    qa:
      'webserver*qa*':
        - webserver
      'db*qa*':
        - db
    prod:
      'webserver*prod*':
        - webserver
      'db*prod*':
        - db

    In this setup we have state trees in three of the four environments, and no state tree in the base environment. Notice that the targets for the minions specify environment data. In Salt the master determines who is in what environment, and many environments can be crossed together. For instance, a separate global state tree could be added to the base environment if it suits your deployment:

    base:
      '*':
        - global
    dev:
      'webserver*dev*':
        - webserver
      'db*dev*':
        - db
    qa:
      'webserver*qa*':
        - webserver
      'db*qa*':
        - db
    prod:
      'webserver*prod*':
        - webserver
      'db*prod*':
        - db

    In this setup all systems will pull the global SLS from the base environment, as well as pull from their respective environments.

    Remember, that since everything is a file in Salt, the environments are primarily file server environments, this means that environments that have nothing to do with states can be defined and used to distribute other files.

    A clean and recommended setup for multiple environments would look like this:

    # Master file_roots configuration:
    file_roots:
      base:
        - /srv/salt/base
      dev:
        - /srv/salt/dev
      qa:
        - /srv/salt/qa
      prod:
        - /srv/salt/prod

    Then only place state trees in the dev, qa and prod environments, leaving the base environment open for generic file transfers. Then the top.sls file would look something like this:

    dev:
      'webserver*dev*':
        - webserver
      'db*dev*':
        - db
    qa:
      'webserver*qa*':
        - webserver
      'db*qa*':
        - db
    prod:
      'webserver*prod*':
        - webserver
      'db*prod*':
        - db

  Other Ways of Targeting Minions

In addition to globs, minions can be specified in top files a few other ways. Some common ones are compound matches and node groups.

Here is a slightly more complex top file example, showing the different types of matches you can perform:

base:
    '*':
        - ldap-client
        - networking
        - salt.minion
    'salt-master*':
        - salt.master
    '^(memcache|web).(qa|prod).loc$':
        - match: pcre
        - nagios.mon.web
        - apache.server
    'os:Ubuntu':
        - match: grain
        - repos.ubuntu
    'os:(RedHat|CentOS)':
        - match: grain_pcre
        - repos.epel
    'foo,bar,baz':
        - match: list
        - database
    'somekey:abc':
        - match: pillar
        - xyz
    'nag1* or G@role:monitoring':
        - match: compound
        - nagios.server

In this example top.sls, all minions get the ldap-client, networking and salt.minion states. Any minion with an id matching the salt-master* glob will get the salt.master state. Any minion with ids matching the regular expression ^(memcache|web).(qa|prod).loc$ will get the nagios.mon.web and apache.server states. All Ubuntu minions will receive the repos.ubuntu state, while all RHEL and CentOS minions will receive the repos.epel state. The minions foo, bar, and baz will receive the database state. Any minion with a pillar named somekey, having a value of abc will receive the xyz state. Finally, minions with ids matching the nag1* glob or with a grain named role equal to monitoring will receive the nagios.server state.

STATE MODULES

State Modules are the components that map to actual enforcement and management of Salt states.

  States are Easy to Write!

State Modules should be easy to write and straightforward. The information passed to the SLS data structures will map directly to the states modules.

Mapping the information from the SLS data is simple, this example should illustrate:

/etc/salt/master: # maps to "name"
  file: # maps to State module filename e.g. https://github.com/saltstack/salt/blob/develop/salt/states/file.py
    - managed # maps to the managed function in the file State module
    - user: root # one of many options passed to the manage function
    - group: root
    - mode: 644
    - source: salt://salt/master

Therefore this SLS data can be directly linked to a module, function and arguments passed to that function.

This does issue the burden, that function names, state names and function arguments should be very human readable inside state modules, since they directly define the user interface.

  Using Custom State Modules

Place your custom state modules inside a _states directory within the file_roots specified by the master config file. These custom state modules can then be distributed in a number of ways. Custom state modules are distributed when state.highstate is run, or by executing the saltutil.sync_states or saltutil.sync_all functions.

  Cross Calling Modules

As with Execution Modules, State Modules can also make use of the __salt__ and __grains__ data.

It is important to note that the real work of state management should not be done in the state module unless it is needed. A good example is the pkg state module. This module does not do any package management work, it just calls the pkg execution module. This makes the pkg state module completely generic, which is why there is only one pkg state module and many backend pkg execution modules.

On the other hand some modules will require that the logic be placed in the state module, a good example of this is the file module. But in the vast majority of cases this is not the best approach, and writing specific execution modules to do the backend work will be the optimal solution.

  Return Data

A State Module must return a dict containing the following keys/values:

•   name: The same value passed to the state as "name".

•   changes: A dict describing the changes made. Each thing changed should be a key, with its value being another dict with keys called "old" and "new" containing the old/new values. For example, the pkg state's changes dict has one key for each package changed, with the "old" and "new" keys in its sub-dict containing the old and new versions of the package.

•   result: A boolean value. True if the action was successful, otherwise False.

•   comment: A string containing a summary of the result.

  Test State

All states should check for and support test being passed in the options. This will return data about what changes would occur if the state were actually run. An example of such a check could look like this:

# Return comment of changes if test.
if __opts__['test']:
    ret['result'] = None
    ret['comment'] = 'State Foo will execute with param {0}'.format(bar)
    return ret

Make sure to test and return before performing any real actions on the minion.

  Watcher Function

If the state being written should support the watch requisite then a watcher function needs to be declared. The watcher function is called whenever the watch requisite is invoked and should be generic to the behavior of the state itself.

The watcher function should accept all of the options that the normal state functions accept (as they will be passed into the watcher function).

A watcher function typically is used to execute state specific reactive behavior, for instance, the watcher for the service module restarts the named service and makes it useful for the watcher to make the service react to changes in the environment.

The watcher function also needs to return the same data that a normal state function returns.

  Mod_init Interface

Some states need to execute something only once to ensure that an environment has been set up, or certain conditions global to the state behavior can be predefined. This is the realm of the mod_init interface.

A state module can have a function called mod_init which executes when the first state of this type is called. This interface was created primarily to improve the pkg state. When packages are installed the package metadata needs to be refreshed, but refreshing the package metadata every time a package is installed is wasteful. The mod_init function for the pkg state sets a flag down so that the first, and only the first, package installation attempt will refresh the package database (the package database can of course be manually called to refresh via the refresh option in the pkg state).

The mod_init function must accept the Low State Data for the given executing state as an argument. The low state data is a dict and can be seen by executing the state.show_lowstate function. Then the mod_init function must return a bool. If the return value is True, then the mod_init function will not be executed again, meaning that the needed behavior has been set up. Otherwise, if the mod_init function returns False, then the function will be called the next time.

A good example of the mod_init function is found in the pkg state module:

def mod_init(low):
    '''
    Refresh the package database here so that it only needs to happen once
    '''
    if low['fun'] == 'installed' or low['fun'] == 'latest':
        rtag = __gen_rtag()
        if not os.path.exists(rtag):
            open(rtag, 'w+').write('')
        return True
    else:
        return False

The mod_init function in the pkg state accepts the low state data as low and then checks to see if the function being called is going to install packages, if the function is not going to install packages then there is no need to refresh the package database. Therefore if the package database is prepared to refresh, then return True and the mod_init will not be called the next time a pkg state is evaluated, otherwise return False and the mod_init will be called next time a pkg state is evaluated.

  salt.states.cmd

  Execution of arbitrary commands.

The cmd state module manages the enforcement of executed commands, this state can tell a command to run under certain circumstances.

  Available Functions

The run function

run Execute a command given certain conditions

    A simple example:

    date > /tmp/salt-run:
    cmd:
        - run

    Only run if another execution failed, in this case truncate syslog if there is no disk space:

    > /var/log/messages:
      cmd.run:
        - unless: echo 'foo' > /tmp/.test

    Note that when executing a command or script, the state(ie, changed or not) of the command is unknown to Salt's state system. Therefore, by default, the cmd state assumes that any command execution results in a changed state.

    This means that if a cmd state is watched by another state then the state that's watching will always be executed due to the changed state in the cmd state.

    Many state functions in this module now also accept a stateful argument. If stateful is specified to be true then it is assumed that the command or script will determine its own state and communicate it back by following a simple protocol described below: If there's nothing in the stdout of the command, then assume no changes. Otherwise, the stdout must be either in JSON or its last non-empty line must be a string of key=value pairs delimited by spaces(no spaces on the sides of =).

    If it's JSON then it must be a JSON object(ie, {}). If it's key=value pairs then quoting may be used to include spaces. (Python's shlex module is used to parse the key=value string)

    Two special keys or attributes are recognized in the output:

    changed: bool (ie, 'yes', 'no', 'true', 'false', case-insensitive)
    comment: str  (ie, any string)

    So, only if 'changed' is true then assume the command execution has changed the state, and any other key values or attributes in the output will be set as part of the changes.

    If there's a comment then it will be used as the comment of the state.

    Here's an example of how one might write a shell script for use with a stateful command:

    #!/bin/bash
    #
    echo "Working hard..."
    # writing the state line
    echo  # an empty line here so the next line will be the last.
    echo "changed=yes comment='something has changed' whatever=123"

    And an example salt file using this module:

    Run myscript:
      cmd.run:
        - name: /path/to/myscript
        - cwd: /
        - stateful: true
    Run only if myscript changed something:
      cmd.wait:
        - name: echo hello
        - cwd: /
        - watch:
          - cmd: Run myscript

    Note that if the cmd.wait state also specfies stateful: true it can then be watched by some other states as well.

    cmd.wait is not restricted to watching only cmd states. For example it can also watch a git state for changes

    # Watch for changes to a git repo and rebuild the project on updates
    my-project:
      git.latest:
        - name: git@github.com/repo/foo
        - target: /opt/foo
        - rev: master
      cmd.wait:
        - name: make install
        - cwd: /opt/foo
        - watch:
          - git: my-project

salt.states.cmd.call(name, func, args=(), kws=None, onlyif=None, unless=None, **kwargs)
    Invoke a pre-defined Python function with arguments specified in the state declaration. This function is mainly used by the salt.renderers.pydsl renderer.

    The intepretation of onlyif and unless arguments are identical to those of salt.states.cmd.run(), and all other arguments(cwd, runas, ...) allowed by cmd.run are allowed here, except that their effects apply only to the commands specified in onlyif and unless rather than to the function to be invoked.

    In addition the stateful argument has no effects here.

    The return value of the invoked function will be interpreted as follows.

    If it's a dictionary then it will be passed through to the state system, which expects it to have the usual structure returned by any salt state function.

    Otherwise, the return value(denoted as result in the code below) is expected to be a JSON serializable object, and this dictionary is returned:

    { 'changes': { 'retval': result },
      'result': True if result is None else bool(result),
      'comment': result if isinstance(result, basestring) else ''
    }

  salt.states.cron

  Management of cron, the Unix command scheduler.

The cron state module allows for user crontabs to be cleanly managed.

Cron declarations require a number of parameters. The timing parameters, need to be declared, minute, hour, daymonth, month and dayweek. The user who's crontab is to be edited also needs to be defined.

By default the timing arguments are all * and the user is root. When making changes to an existing cron job the name declaration is the unique factor, so if and existing cron that looks like this:

date > /tmp/crontest:
  cron.present:
    - user: root
    - minute: 5

Is changed to this:

date > /tmp/crontest:
  cron.present:
    - user: root
    - minute: 7
    - hour: 2

Then the existing cron will be updated, but if the cron command is changed, then a new cron job will be added to the user's crontab.

salt.states.cron.absent(name, user='root', minute='*', hour='*', daymonth='*', month='*', dayweek='*')
    Verifies that the specified cron job is absent for the specified user, only the name is matched when removing a cron job.

name
    The command that should be absent in the user crontab.

user
    The name of the user who's crontab needs to be modified, defaults to the root user

minute
    The information to be set into the minute section, this can be any string supported by your cron system's the minute field. Default is *

hour
    The information to be set in the hour section. Default is *

daymonth
    The information to be set in the day of month section. Default is *

month
    The information to be set in the month section. Default is *

    The information to be set in the day of day of week section. Default is *

salt.states.cron.file(name, source_hash='', user='root', template=None, context=None, replace=True, defaults=None, env=None, backup='', **kwargs)
    Provides file.managed-like functionality (templating, etc.) for a pre-made crontab file, to be assigned to a given user.

name
    The source file to be used as the crontab. This source file can be hosted on either the salt master server, or on an http or ftp server. For files hosted on the salt file server, if the file is located on the master in the directory named spam, and is called eggs, the source string is salt://spam/eggs.

    If the file is hosted on a http or ftp server then the source_hash argument is also required

source_hash
    This can be either a file which contains a source hash string for the source, or a source hash string. The source hash string is the hash algorithm followed by the hash of the file: md5=e138491e9d5b97023cea823fe17bac22

user
    The user to whome the crontab should be assigned. This defaults to root.

template
    If this setting is applied then the named templating engine will be used to render the downloaded file. Currently, jinja and mako are supported.

context

  salt.states.file

  Operations on files, directories and symlinks.

Salt States can aggressively manipulate files on a system. There are a number of ways in which files can be managed.

Regular files can be enforced with the managed function. This function downloads files from the salt master and places them on the target system. The downloaded files can be rendered as a jinja, mako, or wempy template adding a dynamic component to file management. An example of file.managed which makes use of the jinja templating system would look like this:

/etc/http/conf/http.conf:
  file.managed:
    - source: salt://apache/http.conf
    - user: root
    - group: root
    - mode: 644
    - template: jinja
    - context:
        custom_var: "override"
    - defaults:
        custom_var: "default value"
        other_var: 123

Directories can be managed via the directory function. This function can create and enforce the permissions on a directory. A directory statement will look like this:

/srv/stuff/substuf:
  file.directory:
    - user: fred
    - group: users
    - mode: 755
    - makedirs: True

If you need to enforce user and/or group ownership or permissions recursively on the directory's contents, you can do so by adding a recurse directive:

/srv/stuff/substuf:
  file.directory:
    - user: fred
    - group: users
    - mode: 755
    - makedirs: True
    - recurse:
      - user
      - group
      - mode

As a default, mode will resolve to dir_mode and file_mode, to specify both directory and file permissions, use this form:

/srv/stuff/substuf:
  file.directory:
    - user: fred
    - group: users
    - file_mode: 744
    - dir_mode: 755
    - makedirs: True
    - recurse:
      - user
      - group
      - mode

Symlinks can be easily created, the symlink function is very simple and only takes a few arguments:

/etc/grub.conf:
  file.symlink:
    - target: /boot/grub/grub.conf

Recursive directory management can also be set via the recurse function. Recursive directory management allows for a directory on the salt master to be recursively copied down to the minion. This is a great tool for deploying large code and configuration systems. A recurse state would look something like this:

/opt/code/flask:
  file.recurse:
    - source: salt://code/flask
    - include_empty: True

salt.states.file.absent(name)
    Verify that the named file or directory is absent, this will work to reverse any of the functions in the file state module.

name
    The path which should be deleted

salt.states.file.accumulated(name, filename, text, **kwargs)
    Prepare accumulator which can be used in template in file.managed state. accumulator dictionary becomes available in template.

name
    Accumulator name

filename
    Filename which would receive this accumulator (see file.managed state documentation about ''name``)

text
    String or list for adding in accumulator

require_in / watch_in
    One of them required for sure we fill up accumulator before we manage the file. Probably the same as filename

salt.states.file.append(name, text=None, makedirs=False, source=None, source_hash=None, __env__='base')
    Ensure that some text appears at the end of a file

    The text will not be appended again if it already exists in the file. You may specify a single line of text or a list of lines to append.

    Multi-line example:

    /etc/motd:
      file.append:
        - text: |
            Thou hadst better eat salt with the Philosophers of Greece,
            than sugar with the Courtiers of Italy.
            - Benjamin Franklin

    Multiple lines of text:

    /etc/motd:
      file.append:
        - text:
          - Trust no one unless you have eaten much salt with him.
          - Salt is born of the purest of parents: the sun and the sea.

    New in version 0.9.5.

salt.states.file.comment(name, regex, char='#', backup='.bak')
    Comment out specified lines in a file.

path
    The full path to the file to be edited

regex
    A regular expression used to find the lines that are to be commented; this pattern will be wrapped in parenthesis and will move any preceding/trailing ^ or $ characters outside the parenthesis (e.g., the pattern ^foo$ will be rewritten as ^(foo)$) Note that you _need_ the leading ^, otherwise each time you run highstate, another comment char will be inserted.

char
    # The character to be inserted at the beginning of a line in order to comment it out

backup
    .bak The file will be backed up before edit with this file extension

Warning
    This backup will be overwritten each time sed / comment / uncomment is called. Meaning the backup will only be useful after the first invocation.

Usage:

/etc/fstab:
  file.comment:
    - regex: ^bind 127.0.0.1

New in version 0.9.5.

salt.states.file.directory(name, user=None, group=None, recurse=None, dir_mode=None, file_mode=None, makedirs=False, clean=False, require=None, exclude_pat=None, **kwargs)

group
    The group ownership set for the directory, this defaults to the group salt is running as on the minion

recurse
    Enforce user/group ownership and mode of directory recursively. Accepts a list of strings representing what you would like to recurse. Example:

    /var/log/httpd:
        file.directory:

        - group: root
        - dir_mode: 755
        - file_mode: 644

            - user
            - group
            - mode

dir_mode / mode
    The permissions mode to set any directories created.

file_mode
    The permissions mode to set any files created if 'mode' is ran in 'recurse'. This defaults to dir_mode.

makedirs
    If the directory is located in a path without a parent directory, then the state will fail. If makedirs is set to True, then the parent directories will be created to facilitate the creation of the named file.

clean
    Make sure that only files that are set up by salt and required by this function are kept. If this option is set then everything in this directory will be deleted unless it is required.

require
    Require other resources such as packages or files

exclude_pat
    When 'clean' is set to True, exclude this pattern from removal list and preserve in the destination.

salt.states.file.exists(name)

name
    The location of the file to manage

source
    The source file to download to the minion, this source file can be hosted on either the salt master server, or on an http or ftp server. For files hosted on the salt file server, if the file is located on the master in the directory named spam, and is called eggs, the source string is salt://spam/eggs. If source is left blank or None, the file will be created as an empty file and the content will not be managed

    If the file is hosted on a http or ftp server then the source_hash argument is also required

source_hash:
    This can be either a file which contains a source hash string for the source, or a source hash string. The source hash string is the hash algorithm followed by the hash of the file: md5=e138491e9d5b97023cea823fe17bac22

    The file can contain checksums for several files, in this case every line must consist of full name of the file and checksum separated by space:

    If the file is located in a path without a parent directory, then the state will fail. If makedirs is set to True, then the parent directories will be created to facilitate the creation of the named file.

replace
    If this file should be replaced. If false, this command will not overwrite file contents but will enforce permissions if the file exists already. Default is true.

context
    Overrides default context variables passed to the template.

defaults
    Default context passed to the template.

backup
    Overrides the default backup mode for this specific file.

show_diff
    If set to false, the diff will not be shown.

options
    Extra options to pass to patch.

dry_run_first
    True Run patch with --dry-run first to check if it will apply cleanly.

defaults
    Default context passed to the template.

include_empty
    Set this to True if empty directories should also be created (default is False)

include_pat
    When copying, include only this pattern from the source. Default is glob match , if prefixed with E@ then regexp match Example:

    - include_pat: hello*       :: glob matches 'hello01', 'hello02'
                                   ... but not 'otherhello'

                                   'hello01' ...

exclude_pat
    When copying, exclude this pattern from the source. If both include_pat and exclude_pat are supplied, then it will apply conditions cumulatively. i.e. first select based on include_pat and then with in that result, applies exclude_pat.

    Also when 'clean=True', exclude this pattern from the removal list and preserve in the destination. Example:

    - exclude: APPDATA*               :: glob matches APPDATA.01,
                                         APPDATA.02,.. for exclusion

name
    The location of the file to rename to

source
    The location of the file to move to the location specified with name

force:
    If the target location is present then the file will not be moved, specify "force: True" to overwrite the target file

salt.states.file.sed(name, before, after, limit='', backup='.bak', options='-r -e', flags='g')
    Maintain a simple edit to a file

    The file will be searched for the before pattern before making the edit and then searched for the after pattern to verify the edit was successful using salt.modules.file.contains. In general the limit pattern should be as specific as possible and before and after should contain the minimal text to be changed.

    Usage:

    # Disable the epel repo by default
    /etc/yum.repos.d/epel.repo:
      file.sed:
        - before: 1
        - after: 0
        - limit: ^enabled=
    # Remove ldap from nsswitch

Salt can manage software packages via the pkg state module, packages can be set up to be installed, latest, removed and purged. Package management declarations are typically rather simple:

vim:
  pkg.installed

A more involved example involves pulling from a custom repository. Note that the pkgrepo has a require_in clause. This is necessary and can not be replaced by a require clause in the pkg.

pkgrepo.managed:
  - human_name: Logstash PPA
  - name: deb http://ppa.launchpad.net/wolfnet/logstash/ubuntu precise main
  - dist: precise

    Skip the GPG verification check for the package to be installed

version
    Install a specific version of a package. This option is ignored if either "pkgs" or "sources" is used. Currently, this option is supported for the following pkg providers: apt, ebuild, pacman, yumpkg, yumpkg5, and zypper.

    Usage:

    httpd:
      pkg.installed:
        - fromrepo: mycustomrepo

    This function deletes the specified repo on the system, if it exists. It is essentially a wrapper around pkg.del_repo.

name
    The name of the package repo, as it would be referred to when running the regular package manager commands.

ppa On Ubuntu, you can take advantage of Personal Package Archives on Launchpad simply by specifying the user and archive name. EXAMPLE: ppa: wolfnet/logstash

ppa_auth
    For Ubuntu PPAs there can be private PPAs that require authentication to access. For these PPAs the username/password can be specified. This is required for matching if the name format uses the "ppa:" specifier and is private (requires username/password to access, which is encoded in the uri) EXAMPLE: ppa_auth: username:password

salt.states.pkgrepo.managed(name, **kwargs)
    This function manages the configuration on a system that points to the repositories for the system's package manager.

name
    The name of the package repo, as it would be referred to when running the regular package manager commands.

    For yum-based systems, take note of the following configuration values:

humanname
    On yum-based systems, this is stored as the "name" value in the .repo file in /etc/yum.repos.d/. On yum-based systems, this is required.

baseurl
    On yum-based systems, baseurl refers to a direct URL to be used for this yum repo. One of baseurl or mirrorlist is required.

mirrorlist
    a URL which contains a collection of baseurls to choose from. On yum-based systems. One of baseurl or mirrorlist is required.

comments
    Sometimes you want to supply additional information, but not as enabled configuration. Anything supplied for this list will be saved in the repo configuration with a comment marker (#) in front.

    Additional configuration values, such as gpgkey or gpgcheck, are used verbatim to update the options for the yum repo in question.

    For apt-based systems, take note of the following configuration values:

ppa On Ubuntu, you can take advantage of Personal Package Archives on Launchpad simply by specifying the user and archive name. The keyid will be queried from launchpad and everything else is set automatically. You can override any of the below settings by simply setting them as you would normally. EXAMPLE: ppa: wolfnet/logstash

ppa_auth
    For Ubuntu PPAs there can be private PPAs that require authentication to access. For these PPAs the username/password can be passed as an http-basic style username/password combination. EXAMPLE: ppa_auth: username:password

name
    On apt-based systems this must be the complete entry as it would be seen in the sources.list file. This can have a limited subset of components (i.e. 'main') which can be added/modified with the "comps" option. EXAMPLE: name: deb http://us.archive.ubuntu.com/ubuntu/ precise main

disabled
    On apt-based systems, disabled toggles whether or not the repo is used for resolving dependencies and/or installing packages

comps
    On apt-based systems, comps dictate the types of packages to be installed from the repository (e.g. main, nonfree, ...). For purposes of this, comps should be a comma-separated list.

file
    The filename for the .list that the repository is configured in. It is important to include the full-path AND make sure it is in a directory that APT will look in when handling packages

dist
    This dictates the release of the distro the packages should be built for. (e.g. unstable)

keyid
    The KeyID of the GPG key to install. This option also requires the 'keyserver' option to be set.

keyserver
    This is the name of the keyserver to retrieve gpg keys from. The keyid option must also be set for this option to work.

key_url
    A web url to retrieve the GPG key from.

consolidate
    If set to true, this will consolidate all sources definitions to the sources.list file, cleanup the now unused files, consolidate components (e.g. main) for the same uri, type, and architecture to a single line, and finally remove comments from the sources.list file. The consolidate will run every time the state is processed. The option only needs to be set on one repo managed by salt to take effect.

require_in
    Set this to a list of pkg.installed or pkg.lastest to trigger the running of apt-get update prior to attempting to install these packages. Setting a require in the pkg will not work for this.

RENDERERS

The Salt state system operates by gathering information from simple data structures. The state system was designed in this way to make interacting with it generic and simple. This also means that state files (SLS files) can be one of many formats.

By default SLS files are rendered as Jinja templates and then parsed as YAML documents. But since the only thing the state system cares about is raw data, the SLS files can be any structured format that can be dreamed up.

Currently there is support for Jinja + YAML, Mako + YAML, Wempy + YAML, Jinja + json Mako + json and Wempy + json. But renderers can be written to support anything. This means that the Salt states could be managed by XML files, HTML files, puppet files, or any format that can be translated into the data structure used by the state system.

  Multiple Renderers

When deploying a state tree a default renderer is selected in the master configuration file with the renderer option. But multiple renderers can be used inside the same state tree.

When rendering SLS files Salt checks for the presence of a Salt specific shebang line. The shebang line syntax was chosen because it is familiar to the target audience, the systems admin and systems engineer.

The shebang line directly calls the name of the renderer as it is specified within Salt. One of the most common reasons to use multiple renderers in to use the Python or py renderer:

#!py
def run():
    '''
    Install the python-mako package
    '''
    return {'include': ['python'],
            'python-mako': {'pkg': ['installed']}}

The first line is a shebang that references the py renderer.

  Composing Renderers

A renderer can be composed from other renderers by connecting them in a series of pipes(|). In fact, the default Jinja + YAML renderer is implemented by combining a YAML renderer and a Jinja renderer. Such renderer configuration is specified as: jinja | yaml.

Other renderer combinations are possible, here's a few examples:

yaml
    i.e, just YAML, no templating.

mako | yaml
    pass the input to the mako renderer, whose output is then fed into the yaml renderer.

jinja | mako | yaml
    This one allows you to use both jinja and mako templating syntax in the input and then parse the final rendered output as YAML.

    And here's a contrived example sls file using the jinja | mako | yaml renderer:

    #!jinja|mako|yaml
    An_Example:
      cmd.run:
        - name: |
            echo "Using Salt ${grains['saltversion']}" \
                 "from path {{grains['saltpath']}}."
        - cwd: /
    <%doc> ${...} is Mako's notation, and so is this comment. </%doc>
    {#     Similarly, {{...}} is Jinja's notation, and so is this comment. #}

    For backward compatibility, jinja | yaml can also be written as yaml_jinja, and similarly, the yaml_mako, yaml_wempy, json_jinja, json_mako, and json_wempy renderers are all supported as well.

    Keep in mind that not all renderers can be used alone or with any other renderers. For example, the template renderers shouldn't be used alone as their outputs are just strings, which still need to be parsed by another renderer to turn them into highstate data structures. Also, for example, it doesn't make sense to specify yaml | jinja either, because the output of the yaml renderer is a highstate data structure(a dict in Python), which cannot be used as the input to a template renderer. Therefore, when combining renderers, you should know what each renderer accepts as input and what it returns as output.

  Writing Renderers

Writing a renderer is easy, all that is required is that a Python module is placed in the rendered directory and that the module implements the render function. The render function will be passed the path of the SLS file. In the render function, parse the passed file and return the data structure derived from the file. You can place your custom renderers in a _renderers directory within the file_roots specified by the master config file. These custom renderers are distributed when state.highstate is run, or by executing the saltutil.sync_renderers or saltutil.sync_all functions.

  Examples

The best place to find examples of renderers is in the Salt source code. The renderers included with Salt can be found here:

https://github.com/saltstack/salt/blob/develop/salt/renderers

Here is a simple YAML renderer example:

import yaml
def render(yaml_data, env='', sls='', **kws):
    if not isinstance(yaml_data, basestring):
        yaml_data = yaml_data.read()
    data = yaml.load(yaml_data)
    return data if data else {}

  salt.renderers.jinja

  Jinja in States

The most basic usage of Jinja in state files is using control structures to wrap conditional or redundant state elements:

{% if grains['os'] != 'FreeBSD' %}
tcsh:
    pkg:
        - installed
{% endif %}
motd:
  file.managed:
    {% if grains['os'] == 'FreeBSD' %}
    - name: /etc/motd
    {% elif grains['os'] == 'Debian' %}
    - name: /etc/motd.tail
    {% endif %}
    - source: salt://motd

In this example, the first if block will only be evaluated on minions that aren't running FreeBSD, and the second block changes the file name based on the os grain.

Writing if-else blocks can lead to very redundant state files however. In this case, using pillars, or using a previously defined variable might be easier:

{% set motd = ['/etc/motd'] %}
{% if grains['os'] == 'Debian' %}
  {% set motd = ['/etc/motd.tail', '/var/run/motd'] %}
{% endif %}
{% for motdfile in motd %}
{{ motdfile }}:
  file.managed:
    - source: salt://motd
{% endfor %}

Using a variable set by the template, the for loop will iterate over the list of MOTD files to update, adding a state block for each file.

  Passing Variables

It is also possible to pass additional variable context directly into a template, using the defaults and context mappings of the file.managed state:

/etc/motd:
  file.managed:
    - source: salt://motd
    - template: jinja
    - defaults:
      message: 'Foo'
    {% if grains['os'] == 'FreeBSD' %}
    - context:
      message: 'Bar'
    {% endif %}

The template will receive a variable message, which would be accessed in the template using {{ message }}. If the operating system is FreeBSD, the value of the variable message would be Bar, otherwise it is the default Foo

  Include and Import

Includes and imports can be used to share common, reusable state configuration between state files and between files.

{% from 'lib.sls' import test %}

This would import the test template variable or macro, not the test state element, from the file lib.sls. In the case that the included file performs checks again grains, or something else that requires context, passing the context into the included file is required:

{% from 'lib.sls' import test with context %}

  Macros

Macros are helpful for eliminating redundant code, however stripping whitespace from the template block, as well as contained blocks, may be necessary to emulate a variable return from the macro.

# init.sls
{% from 'lib.sls' import pythonpkg with context %}
python-virtualenv:
  pkg.installed:
    - name: {{ pythonpkg('virtualenv') }}
python-fabric:
  pkg.installed:
    - name: {{ pythonpkg('fabric') }}

# lib.sls
{% macro pythonpkg(pkg) -%}
  {%- if grains['os'] == 'FreeBSD' -%}
    py27-{{ pkg }}
  {%- elif grains['os'] == 'Debian' -%}
    python-{{ pkg }}
  {%- endif -%}
{%- endmacro %}

This would define a macro that would return a string of the full package name, depending on the packaging system's naming convention. The whitespace of the macro was eliminated, so that the macro would return a string without line breaks, using whitespace control.

  Jinja in Files

Jinja can be used in the same way in managed files:

# redis.sls
/etc/redis/redis.conf:
    file.managed:
        - source: salt://redis.conf
        - template: jinja
        - context:
            bind: 127.0.0.1

# lib.sls
{% set port = 6379 %}

# redis.conf
{% from 'lib.sls' import port with context %}
port {{ port }}
bind {{ bind }}

As an example, configuration was pulled from the file context and from an external template file.

salt.renderers.jinja.render(template_file, env='', sls='', argline='', context=None, tmplpath=None, **kws)
    Render the template_file, passing the functions and grains into the Jinja rendering system.

Return type
    string

  salt.renderers.json

salt.renderers.json.render(json_data, env='', sls='', **kws)
    Accepts JSON as a string or as a file object and runs it through the JSON parser.

Return type
    A Python data structure

  salt.renderers.mako

salt.renderers.mako.render(template_file, env='', sls='', context=None, tmplpath=None, **kws)
    Render the template_file, passing the functions and grains into the Mako rendering system.

Return type
    string

  salt.renderers.py

Pure python state renderer

The sls file should contain a function called run which returns high state data

salt.renderers.py.render(template, env='', sls='', tmplpath=None, **kws)
    Render the python module's components

Return type
    string

  salt.renderers.pydsl

A Python-based DSL

platform
    all

    The pydsl renderer allows one to author salt formulas(.sls files) in pure Python using a DSL that's easy to write and easy to read. Here's an example:

     #!pydsl
     apache = state('apache')
     apache.pkg.installed()
     apache.service.running()
     state('/var/www/index.html') \
         .file('managed',
               source='salt://webserver/index.html') \
         .require(pkg='apache')

    Notice that any Python code is allow in the file as it's really a Python module, so you have the full power of Python at your disposal. In this module, a few objects are defined for you, including the usual(with __ added) __salt__ dictionary, __grains__, __pillar__, __opts__, __env__, and __sls__, plus a few more: __file__ local file system path to the sls module.

    __pydsl__ Salt PyDSL object, useful for configuring DSL behavior per sls rendering.

    include Salt PyDSL function for creating include declaration's.

    extend Salt PyDSL function for creating extend declaration's.

    state Salt PyDSL function for creating ID declaration's.

    A state ID declaration is created with a state(id) function call. Subsequent state(id) call with the same id returns the same object. This singleton access pattern applys to all declaration objects created with the DSL.

    state('example')
    assert state('example') is state('example')
    assert state('example').cmd is state('example').cmd
    assert state('example').cmd.running is state('example').cmd.running

    The id argument is optional. If omitted, an UUID will be generated and used as the id.

    state(id) returns an object under which you can create a state declaration object by accessing an attribute named after any state module available in Salt.

    state('example').cmd
    state('example').file
    state('example').pkg
    ...

    Then, a function declaration object can be created from a state declaration object by one of the following two ways:

1.  by directly calling the attribute named for the state declaration, and supplying the state function name as the first argument.

    state('example').file('managed', ...)

2.  by calling a method named after the state function on the state declaration object.

    state('example').file.managed(...)

    With either way of creating a function declaration object, any function arg declaration's can be passed as keyword arguments to the call. Subsequent calls of a function declaration will update the arg declarations.

    state('example').file('managed', source='salt://webserver/index.html')
    state('example').file.managed(source='salt://webserver/index.html')

    As a shortcut, the special name argument can also be passed as the first(second if calling using the first way) positional argument.

    state('example').cmd('run', 'ls -la', cwd='/')
    state('example').cmd.run('ls -la', cwd='/')

    Finally, a requisite declaration object with its requisite reference's can be created by invoking one of the requisite methods(require, watch, use, require_in, watch_in, and use_in) on either a function declaration object or a state declaration object. The return value of a requisite call is also a function declaration object, so you can chain several requisite calls together.

    Arguments to a requisite call can be a list of state declaration objects and/or a set of keyword arguments whose names are state modules and values are IDs of ID declaration's or names of name declaration's.

    apache2 = state('apache2')
    apache2.pkg.installed()
    state('libapache2-mod-wsgi').pkg.installed()
    # you can call requisites on function declaration
    apache2.service.running() \
                   .require(apache2.pkg,
                            pkg='libapache2-mod-wsgi') \
                   .watch(file='/etc/apache2/httpd.conf')
    # or you can call requisites on state declaration.
    # this actually creates an anonymous function declaration object
    # to add the requisites.
    apache2.service.require(state('libapache2-mod-wsgi').pkg,
                            pkg='apache2') \
                   .watch(file='/etc/apache2/httpd.conf')

    # we still need to set the name of the function declaration.
    apache2.service.running()

    include declaration objects can be created with the include function, while extend declaration objects can be created with the extend function, whose arguments are just function declaration objects.

    include('edit.vim', 'http.server')
    extend(state('apache2').service.watch(file='/etc/httpd/httpd.conf')

    The include function, by default, causes the included sls file to be rendered as soon as the include function is called. It returns a list of rendered module objects; sls files not rendered with the pydsl renderer return None's. This behavior creates no include declaration's in the resulting high state data structure.

    import types
    # including multiple sls returns a list.
    _, mod = include('a-non-pydsl-sls', 'a-pydsl-sls')
    assert _ is None
    assert isinstance(slsmods[1], types.ModuleType)
    # including a single sls returns a single object
    mod = include('a-pydsl-sls')
    # myfunc is a function that calls state(...) to create more states.
    mod.myfunc(1, 2, "three")

    Notice how you can define a reusable function in your pydsl sls module and then call it via the module returned by include.

    It's still possible to do late includes by passing the delayed=True keyword argument to include.

    include('edit.vim', 'http.server', delayed=True)

    Above will just create a include declaration in the rendered result, and such call always returns None.

  Special integration with the cmd state

Taking advantage of rendering a Python module, PyDSL allows you to declare a state that calls a pre-defined Python function when the state is executed.

greeting = "hello world"
def helper(something, *args, **kws):
    print greeting                # hello world
    print something, args, kws    # test123 ['a', 'b', 'c'] {'x': 1, 'y': 2}

state().cmd.call(helper, "test123", 'a', 'b', 'c', x=1, y=2)

The cmd.call state function takes care of calling our helper function with the arguments we specified in the states, and translates the return value of our function into a structure expected by the state system. See salt.states.cmd.call() for more information.

  Implicit ordering of states

Salt states are explicitly ordered via requisite declaration's. However, with pydsl it's possible to let the renderer track the order of creation for function declaration objects, and implicitly add require requisites for your states to enforce the ordering. This feature is enabled by setting the ordered option on __pydsl__.

Note
    this feature is only available if your minions are using Python >= 2.7.

include('some.sls.file')
A = state('A').cmd.run(cwd='/var/tmp')
extend(A)
__pydsl__.set(ordered=True)
for i in range(10):
    i = str(i)
    state(i).cmd.run('echo '+i, cwd='/')
state('1').cmd.run('echo one')
state('2').cmd.run(name='echo two')

Notice that the ordered option needs to be set after any extend calls. This is to prevent pydsl from tracking the creation of a state function that's passed to an extend call.

Above example should create states from 0 to 9 that will output 0, one, two, 3, ... 9, in that order.

It's important to know that pydsl tracks the creations of function declaration objects, and automatically adds a require requisite to a function declaration object that requires the last function declaration object created before it in the sls file.

This means later calls(perhaps to update the function's function arg declaration) to a previously created function declaration will not change the order.

  Render time state execution

When Salt processes a salt formula file(.sls), the file is rendered to salt's high state data representation by a renderer before the states can be executed. In the case of the pydsl renderer, the .sls file is executed as a python module as it is being rendered which makes it easy to execute a state at render time. In pydsl, executing one or more states at render time can be done by calling a configured ID declaration object.

#!pydsl
s = state() # save for later invocation
# configure it
s.cmd.run('echo at render time', cwd='/')
s.file.managed('target.txt', source='salt://source.txt')
s() # execute the two states now

Once an ID declaration is called at render time it is detached from the sls module as if it was never defined.

Note
    If implicit ordering is enabled(ie, via __pydsl__.set(ordered=True)) then the first invocation of a ID declaration object must be done before a new function declaration is created.

  Integration with the stateconf renderer

The salt.renderers.stateconf renderer offers a few interesting features that can be leveraged by the pydsl renderer. In particular, when using with the pydsl renderer, we are interested in stateconf's sls namespacing feature(via dot-prefixed id declarations), as well as, the automatic start and goal states generation.

Now you can use pydsl with stateconf like this:

#!pydsl|stateconf -ps
include('xxx', 'yyy')
# ensure that states in xxx run BEFORE states in this file.
extend(state('.start').stateconf.require(stateconf='xxx::goal'))
# ensure that states in yyy run AFTER states in this file.
extend(state('.goal').stateconf.require_in(stateconf='yyy::start'))
__pydsl__.set(ordered=True)
...

-s enables the generation of a stateconf start state, and -p lets us pipe high state data rendered by pydsl to stateconf. This example shows that by require-ing or require_in-ing the included sls' start or goal states, it's possible to ensure that the included sls files can be made to execute before or after a state in the including sls file.

salt.renderers.pydsl.render(template, env='', sls='', tmplpath=None, rendered_sls=None, **kws)

  salt.renderers.stateconf

    Jack Kuan <kjkuan@gmail.com>

maturity
    new

platform
    all

    This module provides a custom renderer that process a salt file with a specified templating engine(e.g., Jinja) and a chosen data renderer(e.g., YAML), extract arguments for any stateconf.set state and provide the extracted arguments (including salt specific args, such as 'require', etc) as template context. The goal is to make writing reusable/configurable/ parameterized salt files easier and cleaner.

    To use this renderer, either set it as the default renderer via the renderer option in master/minion's config, or use the shebang line in each individual sls file, like so: #!stateconf. Note, due to the way this renderer works, it must be specified as the first renderer in a render pipeline. That is, you cannot specify #!mako|yaml|stateconf, for example. Instead, you specify them as renderer arguments: #!stateconf mako . yaml.

    Here's a list of features enabled by this renderer.

•   Prefixes any state id(declaration or reference) that starts with a dot(.) to avoid duplicated state ids when the salt file is included by other salt files.

    For example, in the salt://some/file.sls, a state id such as .sls_params will be turned into some.file::sls_params. Example:

    #!stateconf yaml . jinja
    .vim:
      package.installed

    Above will be translated into:

    some.file::vim:
      package.installed:
        - name: vim

    Notice how that if a state under a dot-prefixed state id has no name argument then one will be added automatically by using the state id with the leading dot stripped off.

    The leading dot trick can be used with extending state ids as well, so you can include relatively and extend relatively. For example, when extending a state in salt://some/other_file.sls, e.g.,:

    #!stateconf yaml . jinja
    include:
      - .file
    extend:
      .file::sls_params:
        stateconf.set:
          - name1: something

    Above will be pre-processed into:

    include:
      - some.file
    extend:
      some.file::sls_params:
        stateconf.set:
          - name1: something

•   Adds a sls_dir context variable that expands to the directory containing the rendering salt file. So, you can write salt://{{sls_dir}}/... to reference templates files used by your salt file.

•   Recognizes the special state function, stateconf.set, that configures a default list of named arguments usable within the template context of the salt file. Example:

    #!stateconf yaml . jinja
    .sls_params:
      stateconf.set:
        - name1: value1
        - name2: value2
        - name3:
          - value1
          - value2
          - value3
        - require_in:
          - cmd: output
    # --- end of state config ---
    .output:
      cmd.run:
        - name: |
            echo 'name1={{sls_params.name1}}
                  name2={{sls_params.name2}}
                  name3[1]={{sls_params.name3[1]}}
            '

    This even works with include + extend so that you can override the default configured arguments by including the salt file and then extend the stateconf.set states that come from the included salt file. (IMPORTANT: Both the included and the extending sls files must use the stateconf renderer for this ``extend`` to work!)

    Notice that the end of configuration marker(# --- end of state config --) is needed to separate the use of 'stateconf.set' form the rest of your salt file. The regex that matches such marker can be configured via the stateconf_end_marker option in your master or minion config file.

    Sometimes, you'd like to set a default argument value that's based on earlier arguments in the same stateconf.set. For example, you may be tempted to do something like this:

    #!stateconf yaml . jinja
    .apache:
      stateconf.set:
        - host: localhost
        - port: 1234
        - url: 'http://{{host}}:{{port}}/'
    # --- end of state config ---
    .test:
      cmd.run:
        - name: echo '{{apache.url}}'
        - cwd: /

    However, this won't work, but can be worked around like so:

    #!stateconf yaml . jinja
    .apache:
      stateconf.set:
        - host: localhost
        - port: 1234
    {#  - url: 'http://{{host}}:{{port}}/' #}
    # --- end of state config ---
    # {{ apache.setdefault('url', "http://%(host)s:%(port)s/" % apache) }}
    .test:
      cmd.run:
        - name: echo '{{apache.url}}'
        - cwd: /

•   Adds support for relative include and exclude of .sls files. Example:

    #!stateconf yaml . jinja
    include:
      - .apache
      - .db.mysql
    exclude:
      - sls: .users

    If the above is written in a salt file at salt://some/where.sls then it will include salt://some/apache.sls and salt://some/db/mysql.sls, and exclude salt://some/users.ssl. Actually, it does that by rewriting the above include and exclude into:

    include:
      - some.apache
      - some.db.mysql
    exclude:
      - sls: some.users

•   Optionally(enabled by default, disable via the -G renderer option, e.g., in the shebang line: #!stateconf -G), generates a stateconf.set goal state(state id named as .goal by default, configurable via the master/minion config option, stateconf_goal_state) that requires all other states in the salt file. Note, the .goal state id is subject to dot-prefix rename rule mentioned earlier.

    Such goal state is intended to be required by some state in an including salt file. For example, in your webapp salt file, if you include a sls file that is supposed to setup Tomcat, you might want to make sure that all states in the Tomcat sls file will be executed before some state in the webapp sls file.

•   Optionally(enable via the -o renderer option, e.g., in the shebang line: #!stateconf -o), orders the states in a sls file by adding a require requisite to each state such that every state requires the state defined just before it. The order of the states here is the order they are defined in the sls file.(Note: this feature is only available if your minions are using Python >= 2.7. For Python2.6, it should also work if you install the ordereddict module from PyPI)

    By enabling this feature, you are basically agreeing to author your sls files in a way that gives up the explicit(or implicit?) ordering imposed by the use of require, watch, require_in or watch_in requisites, and instead, you rely on the order of states you define in the sls files. This may or may not be a better way for you. However, if there are many states defined in a sls file, then it tends to be easier to see the order they will be executed with this feature.

    You are still allowed to use all the requisites, with a few restrictions. You cannot require or watch a state defined after the current state. Similarly, in a state, you cannot require_in or watch_in a state defined before it. Breaking any of the two restrictions above will result in a state loop. The renderer will check for such incorrect uses if this feature is enabled.

    Additionally, names declarations cannot be used with this feature because the way they are compiled into low states make it impossible to guarantee the order in which they will be executed. This is also checked by the renderer. As a workaround for not being able to use names, you can achieve the same effect, by generate your states with the template engine available within your sls file.

    Finally, with the use of this feature, it becomes possible to easily make an included sls file execute all its states after some state(say, with id X) in the including sls file. All you have to do is to make state, X, require_in the first state defined in the included sls file.

    When writing sls files with this renderer, you should avoid using what can be defined in a name argument of a state as the state's id. That is, avoid writing your states like this:

    /path/to/some/file:
      file.managed:
        - source: salt://some/file
    cp /path/to/some/file file2:
      cmd.run:
        - cwd: /
        - require:
          - file: /path/to/some/file

    Instead, you should define the state id and the name argument separately for each state, and the id should be something meaningful and easy to reference within a requisite(which I think is a good habit anyway, and such extra indirection would also makes your sls file easier to modify later). Thus, the above states should be written like this:

    add-some-file:
      file.managed:
        - name: /path/to/some/file
        - source: salt://some/file
    copy-files:
      cmd.run:
        - name: cp /path/to/some/file file2
        - cwd: /
        - require:
          - file: add-some-file

    Moreover, when referencing a state from a requisite, you should reference the state's id plus the state name rather than the state name plus its name argument. (Yes, in the above example, you can actually require the file: /path/to/some/file, instead of the file: add-some-file). The reason is that this renderer will re-write or rename state id's and their references for state id's prefixed with .. So, if you reference name then there's no way to reliably rewrite such reference.

PILLARS

Salt includes a number of built-in external pillars, listed at all-salt.pillars.

You may also wish to look at the standard pillar documentation, at pillar-configuration

The source for the built-in Salt pillars can be found here: https://github.com/saltstack/salt/blob/develop/salt/pillar

FULL LIST OF BUILTIN PILLAR MODULES

cmd_yaml | Execute a command and read the output as YAML. The YAML data is then directly
hiera | Take in a hiera configuration file location and execute it.
mongo | Read pillar data from a mongodb collection.

  salt.pillar.cmd_json

Execute a command and read the output as JSON. The JSON data is then directly overlaid onto the minion's pillar data

salt.pillar.cmd_json.ext_pillar(pillar, command)
    Execute a command and read the output as JSON

  salt.pillar.cmd_yaml

Execute a command and read the output as YAML. The YAML data is then directly overlaid onto the minion's pillar data

salt.pillar.cmd_yaml.ext_pillar(pillar, command)
    Execute a command and read the output as YAML

salt.pillar.hiera.ext_pillar(pillar, conf)
    Execute hiera and return the data

  salt.pillar.mongo

Read pillar data from a mongodb collection.

This module will load a node-specific pillar dictionary from a mongo collection. It uses the node's id for lookups and can load either the whole document, or just a specific field from that document as the pillar dictionary.

  Salt Master Mongo Configuration

The module shares the same base mongo connection variables as salt.returners.mongo_return. These variables go in your master config file.

•   mongo.db - The mongo database to connect to. Defaults to 'salt'.

•   mongo.host - The mongo host to connect to. Supports replica sets by specifying all hosts in the set, comma-delimited. Defaults to 'salt'.

•   mongo.port - The port that the mongo database is running on. Defaults to 27017.

•   mongo.user - The username for connecting to mongo. Only required if you are using mongo authentication. Defaults to ''.

•   mongo.password - The password for connecting to mongo. Only required if you are using mongo authentication. Defaults to ''.

  Configuring the Mongo ext_pillar

The Mongo ext_pillar takes advantage of the fact that the Salt Master configuration file is yaml. It uses a sub-dictionary of values to adjust specific features of the pillar. This is the explicit single-line dictionary notation for yaml. One may be able to get the easier-to-read multine dict to work correctly with some experimentation.

ext_pillar:
  - mongo: {collection: vm, id_field: name, re_pattern: \.example\.com, fields: [customer_id, software, apache_vhosts]}

In the example above, we've decided to use the vm collection in the database to store the data. Minion ids are stored in the name field on documents in that collection. And, since minon ids are FQDNs in most cases, we'll need to trim the domain name in order to find the minon by hostname in the collection. When we find a minion, return only the customer_id, software, and apache_vhosts fields, as that will contain the data we want for a given node. They will be available directly inside the pillar dict in your SLS templates.

  Module Documentation

salt.pillar.mongo.ext_pillar(pillar, collection='pillar', id_field='_id', re_pattern=None, re_replace='', fields=None)
    Connect to a mongo database and read per-node pillar information.

Parameters:

•   collection: The mongodb collection to read data from. Defaults to 'pillar'.

•   id_field: The field in the collection that represents an individual minon id. Defaults to '_id'.

•   re_pattern: If your naming convention in the collection is shorter than the minion id, you can use this to trim the name. re_pattern will be used to match the name, and re_replace will be used to replace it. Backrefs are supported as they are in the Python standard library. If None, no mangling of the name will be performed - the collection will be searched with the entire minion id. Defaults to None.

•   re_replace: Use as the replacement value in node ids matched with re_pattern. Defaults to ''. Feel free to use backreferences here.

•   fields: The specific fields in the document to use for the pillar data. If None, will use the entire document. If using the entire document, the _id field will be converted to string. Be careful with other fields in the document as they must be string serializable. Defaults to None.

  salt.pillar.pillar_ldap

This pillar module parses a config file (specified in the salt master config), and executes a series of LDAP searches based on that config. Data returned by these searches is aggregrated, with data items found later in the LDAP search order overriding data found earlier on. The final result set is merged with the pillar data.

salt.pillar.pillar_ldap.ext_pillar(pillar, config_file)
    Execute LDAP searches and return the aggregated data

  salt.pillar.puppet

Execute an unmodified puppet_node_classifier and read the output as YAML. The YAML data is then directly overlaid onto the minion's pillar data.

  salt.tops.ext_nodes

  External Nodes Classifier

The External Nodes Classifier is a master tops subsystem used to hook into systems used to provide mapping information used by major configuration management systems. One of the most common external nodes classification system is provided by Cobbler and is called cobbler-ext-nodes.

The cobbler-ext-nodes command can be used with this configuration:

master_tops:
  ext_nodes: cobbler-ext-nodes

It is noteworthy that the Salt system does not directly ingest the data sent from the cobbler-ext-nodes command, but converts the data into information that is used by a Salt top file.

salt.tops.ext_nodes.top(**kwargs)
    Run the command configured

  salt.tops.cobbler

  Cobbler Tops

Cobbler Tops is a master tops subsystem used to look up mapping information from Cobbler via its API. The same cobbler.* parameters are used for both the Cobbler tops and Cobbler pillar modules.

master_tops:
  cobbler: {}
cobbler.url: https://example.com/cobbler_api #default is http://localhost/cobbler_api
cobbler.user: username # default is no username
cobbler.password: password # default is no password

  Module Documentation

salt.tops.cobbler.top(**kwargs)
    Look up top data in Cobbler for for a minion.

  salt.tops.mongo

Read tops data from a mongodb collection.

This module will load tops data from a mongo collection. It uses the node's id for lookups.

  Salt Master Mongo Configuration

The module shares the same base mongo connection variables as salt.returners.mongo_return. These variables go in your master config file.

•   mongo.db - The mongo database to connect to. Defaults to 'salt'.

•   mongo.host - The mongo host to connect to. Supports replica sets by specifying all hosts in the set, comma-delimited. Defaults to 'salt'.

•   environment_field: The name of the field providing the environment. Defaults to environment.

SALT RUNNERS

    The full list of runners

Salt runners are convenience applications executed with the salt-run command.

A Salt runner can be a simple client call, or a complex application.

The use for a Salt runner is to build a frontend hook for running sets of commands via Salt or creating special formatted output.

  Writing Salt Runners

Salt runners can be easily written, the work in a similar way to Salt modules except they run on the server side.

A runner is a Python module that contains functions, each public function is a runner that can be executed via the salt-run command.

If a Python module named test.py is created in the runners directory and contains a function called foo then the function could be called with:

# salt-run test.foo

  Examples

The best examples of runners can be found in the Salt source:

https://github.com/saltstack/salt/blob/develop/salt/runners

A simple runner that returns a well-formatted list of the minions that are responding to Salt calls would look like this:

# Import salt modules
import salt.client
def up():
    '''
    Print a list of all of the minions that are up
    '''
    client = salt.client.LocalClient(__opts__['conf_file'])
    minions = client.cmd('*', 'test.ping', timeout=1)
    for minion in sorted(minions):
        print minion

  salt.output.grains

Special outputter for grains

salt.output.grains.output(grains)

  salt.output.highstate

The return data from the Highstate command is a standard data structure which is parsed by the highstate outputter to deliver a clean and readable set of information about the HighState run on minions.

Two configurations can be set to modify the highstate outputter. These values can be set in the master config to change the output of the salt command or set in the minion config to change the output of the salt-call command.

state_verbose:
    By default state_verbose is set to True, setting this to False will instruct the highstate outputter to omit displaying anything in green, this means that nothing with a result of True and no changes will not be printed

state_output:
    The highstate outputter has two output modes, full and terse. The default is set to full, which will display many lines of detailed information for each executed chunk. If the state_output option is set to terse then the output is greatly simplified and shown in only one line

salt.output.highstate.output(data)
    The HighState Outputter is only meant to be used with the state.highstate function, or a function that returns highstate return data.

PEER COMMUNICATION

Salt 0.9.0 introduced the capability for Salt minions to publish commands. The intent of this feature is not for Salt minions to act as independent brokers one with another, but to allow Salt minions to pass commands to each other.

In Salt 0.10.0 the ability to execute runners from the master was added. This allows for the master to return collective data from runners back to the minions via the peer interface.

The peer interface is configured through two options in the master configuration file. For minions to send commands from the master the peer configuration is used. To allow for minions to execute runners from the master the peer_run configuration is used.

Since this presents a viable security risk by allowing minions access to the master publisher the capability is turned off by default. The minions can be allowed access to the master publisher on a per minion basis based on regular expressions. Minions with specific ids can be allowed access to certain Salt modules and functions.

  Peer Configuration

The configuration is done under the peer setting in the Salt master configuration file, here are a number of configuration possibilities.

The simplest approach is to enable all communication for all minions, this is only recommended for very secure environments.

peer:
  .*:
    - .*

This configuration will allow minions with IDs ending in example.com access to the test, ps, and pkg module functions.

peer:
  .*example.com:
    - test.*
    - ps.*
    - pkg.*

The configuration logic is simple, a regular expression is passed for matching minion ids, and then a list of expressions matching minion functions is associated with the named minion. For instance, this configuration will also allow minions ending with foo.org access to the publisher.

peer:
  .*example.com:
    - test.*
    - ps.*
    - pkg.*
  .*foo.org:
    - test.*
    - ps.*
    - pkg.*

  Peer Runner Communication

Configuration to allow minions to execute runners from the master is done via the peer_run option on the master. The peer_run configuration follows the same logic as the peer option. The only difference is that access is granted to runner modules.

To open up access to all minions to all runners:

peer_run:
  .*:
    - .*

This configuration will allow minions with IDs ending in example.com access to the manage and jobs runner functions.

peer_run:
  .*example.com:
    - manage.*
    - jobs.*

  Using Peer Communication

The publish module was created to manage peer communication. The publish module comes with a number of functions to execute peer communication in different ways. Currently there are three functions in the publish module. These examples will show how to test the peer system via the salt-call command.

To execute test.ping on all minions:

# salt-call publish.publish \* test.ping

To execute the manage.up runner:

# salt-call publish.runner manage.up

CLIENT ACL SYSTEM

The salt client ACL system is a means to allow system users other than root to have access to execute select salt commands on minions from the master.

The client ACL system is configured in the master configuration file via the client_acl configuration option. Under the client_acl configuration option the users open to send commands are specified and then a list of regular expressions which specify the minion functions which will be made available to specified user. This configuration is much like the peer configuration:

# Allow thatch to execute anything and allow fred to use ping and pkg
client_acl:
  thatch:
    - .*
  fred:
    - ping.*
    - pkg.*

  Permission Issues

Directories required for client_acl must be modified to be readable by the users specified:

chmod 755 /var/cache/salt /var/cache/salt/jobs /var/run/salt

If you are upgrading from earlier versions of salt you must also remove any existing user keys and re-start the Salt master:

rm /var/cache/salt/.*key
service salt-master restart

SALT SYNDIC

The Salt Syndic interface is a powerful tool which allows for the construction of Salt command topologies. A basic Salt setup has a Salt Master commanding a group of Salt Minions. The Syndic interface is a special passthrough minion, it is run on a master and connects to another master, then the master that the Syndic minion is listening to can control the minions attached to the master running the syndic.

The intent for supporting many layouts is not presented with the intent of supposing the use of any single topology, but to allow a more flexible method of controlling many systems.

  Configuring the Syndic

Since the Syndic only needs to be attached to a higher level master the configuration is very simple. On a master that is running a syndic to connect to a higher level master the syndic_master option needs to be set in the master config file. The syndic_master option contains the hostname or IP address of the master server that can control the master that the syndic is running on.

The master that the syndic connects to sees the syndic as an ordinary minion, and treats it as such. the higher level master will need to accept the syndic's minion key like any other minion. This master will also need to set the order_masters value in the configuration to True. The order_masters option in the config on the higher level master is very important, to control a syndic extra information needs to be sent with the publications, the order_masters option makes sure that the extra data is sent out.

  Running the Syndic

The Syndic is a separate daemon that needs to be started on the master that is controlled by a higher master. Starting the Syndic daemon is the same as starting the other Salt daemons.

PYTHON CLIENT API

Salt is written to be completely API centric, Salt minions and master can be built directly into third party applications as a communication layer. The Salt client API is very straightforward.

A number of client command methods are available depending on the exact behavior desired.

  Using the LocalClient API

Sending information through the client is simple:

# Import the Salt client library
import salt.client
# create a local client object
client = salt.client.LocalClient()
# make calls with the cmd method
ret = client.cmd('*', 'cmd.run', ['ls -l'])

The LocalClient object only works running as root on the salt-master, it is the same interface used by the salt command line tool.

LocalClient.cmd(tgt, fun, arg=[], timeout=5, expr_form='glob', ret='')
    The cmd method will execute and wait for the timeout period for all minions to reply, then it will return all minion data at once.

tgt The tgt option is the target specification, by default a target is passed in as a bash shell glob. The expr_form option allows the tgt to be passed as either a PCRE regular expression or as a Python list.

fun The name of the function to call on the specified minions. The documentation for these functions can be seen by running on the salt-master: salt '*' sys.doc

arg The optional arg parameter is used to pass a list of options on to the remote function

timeout
    The number of seconds to wait after the last minion returns but before all minions return.

expr_form
    The type of tgt that is passed in, the allowed values are:

•   'glob' - Bash glob completion - Default

•   'pcre' - Perl style regular expression

•   'list' - Python list of hosts

•   'grain' - Match based on a grain comparison

•   'grain_pcre' - Grain comparison with a regex

•   'pillar' - Pillar data comparison

•   'nodegroup' - Match on nodegroup

•   'range' - Use a Range server for matching

•   'compound' - Pass a compound match string

ret Specify the returner to use. The value passed can be single returner, or a comma delimited list of returners to call in order on the minions

LocalClient.cmd_cli(tgt, fun, arg=[], timeout=5, verbose=False, expr_form='glob', ret='')
    The cmd_cli method is used by the salt command, it is a generator. This method returns minion returns as the come back and attempts to block until all minions return.

tgt The tgt option is the target specification, by default a target is passed in as a bash shell glob. The expr_form option allows the tgt to be passed as either a pcre regular expression or as a Python list.

fun The name of the function to call on the specified minions. The documentation for these functions can be seen by running on the salt-master: salt '*' sys.doc

arg The optional arg parameter is used to pass a list of options on to the remote function

timeout
    The number of seconds to wait after the last minion returns but before all minions return.

expr_form
    The type of tgt that is passed in, the allowed values are:

•   'glob' - Bash glob completion - Default

•   'pcre' - Perl style regular expression

•   'list' - Python list of hosts

•   'grain' - Match based on a grain comparison

•   'grain_pcre' - Grain comparison with a regex

•   'pillar' - Pillar data comparison

•   'nodegroup' - Match on nodegroup

•   'range' - Use a Range server for matching

•   'compound' - Pass a compound match string

ret Specify the returner to use. The value passed can be single returner, or a comma delimited list of returners to call in order on the minions

verbose
    Print extra information about the running command to the terminal

LocalClient.cmd_iter(tgt, fun, arg=[], timeout=5, expr_form='glob', ret='')
    The cmd_iter method is a generator which yields the individual minion returns as the come in.

tgt The tgt option is the target specification, by default a target is passed in as a bash shell glob. The expr_form option allows the tgt to be passed as either a pcre regular expression or as a Python list.

fun The name of the function to call on the specified minions. The documentation for these functions can be seen by running on the salt-master: salt '*' sys.doc

arg The optional arg parameter is used to pass a list of options on to the remote function

timeout
    The number of seconds to wait after the last minion returns but before all minions return.

expr_form
    The type of tgt that is passed in, the allowed values are:

•   'glob' - Bash glob completion - Default

•   'pcre' - Perl style regular expression

•   'list' - Python list of hosts

•   'grain' - Match based on a grain comparison

•   'grain_pcre' - Grain comparison with a regex

•   'pillar' - Pillar data comparison

•   'nodegroup' - Match on nodegroup

•   'range' - Use a Range server for matching

•   'compound' - Pass a compound match string

ret Specify the returner to use. The value passed can be single returner, or a comma delimited list of returners to call in order on the minions

LocalClient.cmd_iter_no_block(tgt, fun, arg=[], timeout=5, expr_form='glob', ret='')
    The cmd_iter method will block waiting for individual minions to return, the cmd_iter_no_block method will return None until the next minion returns. This allows for actions to be injected in between minion returns

tgt The tgt option is the target specification, by default a target is passed in as a bash shell glob. The expr_form option allows the tgt to be passed as either a pcre regular expression or as a Python list.

fun The name of the function to call on the specified minions. The documentation for these functions can be seen by running on the salt-master: salt '*' sys.doc

arg The optional arg parameter is used to pass a list of options on to the remote function

timeout
    The number of seconds to wait after the last minion returns but before all minions return.

expr_form
    The type of tgt that is passed in, the allowed values are:

•   'glob' - Bash glob completion - Default

•   'pcre' - Perl style regular expression

•   'list' - Python list of hosts

•   'grain' - Match based on a grain comparison

•   'grain_pcre' - Grain comparison with a regex

•   'pillar' - Pillar data comparison

•   'nodegroup' - Match on nodegroup

•   'range' - Use a Range server for matching

•   'compound' - Pass a compound match string

ret Specify the returner to use. The value passed can be single returner, or a comma delimited list of returners to call in order on the minions

  Compound Command Execution With the Salt API

The Salt client API can also send what is called a compound command. Often a collection of commands need to be executed on the targeted minions, rather than send the commands one after another, they can be sent in a single publish containing a series of commands. This can dramatically lower overhead and speed up the application communicating with Salt.

When commands are executed with compound execution the minion functions called are executed in serial on the minion and the return value is sent back in a different fashion. The return value is a dict, with the function names as keys to the function returns as values.

Using the compound command execution system via the API requires that the fun value and the arg value are lists matching by index. This ensures that the order of the executions can be controlled. Any function that has no arguments MUST have an empty array in the corresponding arg index.

All client command methods can execute compound commands.

# Import the Salt client library
import salt.client
# create a local client object
client = salt.client.LocalClient()
# make compound execution calls with the cmd method
ret = client.cmd('*', ['cmd.run', 'test.ping', 'test.echo'], [['ls -l'], [], ['foo']])

This will execute cmd.run ls -l then test.ping and finally test.echo foo. The return data from the minion will look like this:

{'cmd.run': '<output from ls -l>',
 'test.ping': True,
 'test.echo': 'foo'}

  Salt Caller API

The Salt minion caller api can be used to simplify the execution and use of minion elements. The caller api is useful for accessing the Salt api, direct access to the state functions, using the matcher interface on a single minion, and as an api for the peer interface. Using the api is fairly straightforward:

# Import the Salt client library
import salt.client
# Create the caller object
caller = salt.client.Caller()
# call a function
caller.function('test.ping')
# Call objects directly:
caller.sminion.functions['cmd.run']('ls -l')

FILE SERVER BACKENDS

Salt version 0.12.0 introduced the ability for the Salt Master to integrate different file server backends. File server backends allows the Salt file server to act as a transparent bridge to external resources. The primary example of this is the git backend which allows for all of the Salt formulas and files to be maintained in a remote git repository.

The fileserver backend system can accept multiple backends as well. This makes it possible to have the environments listed in the file_roots configuration available in addition to other backends, or the ability to mix multiple backends.

This feature is managed by the fileserver_backend option in the master config. The desired backend systems are listed in order of search priority:

fileserver_backend:
  - roots
  - git

If this configuration the environments and files defined in the file_roots configuration will be searched first, if the referenced environment and file is not found then the git backend will be searched.

  Environments

The concept of environments is followed in all backend systems. The environments in the classic roots backend are defined in the file_roots option. Environments map differently based on the backend, for instance the git backend translated branches and tags in git to environments. This makes it easy to define environments in git by just setting a tag or forking a branch.

DYNAMIC MODULE DISTRIBUTION

New in version 0.9.5.

Salt Python modules can be distributed automatically via the Salt file server. Under the root of any environment defined via the file_roots option on the master server directories corresponding to the type of module can be used.

Module sync
    Automatically transfer and load modules, grains, renderers, returners, states, etc from the master to the minions.

    The directories are prepended with an underscore:

1.  _modules

2.  _grains

3.  _renderers

4.  _returners

5.  _states

    The contents of these directories need to be synced over to the minions after Python modules have been created in them. There are a number of ways to sync the modules.

  Sync Via States

The minion configuration contains an option autoload_dynamic_modules which defaults to True. This option makes the state system refresh all dynamic modules when states are run. To disable this behavior set autoload_dynamic_modules to False in the minion config.

When dynamic modules are autoloaded via states, modules only pertinent to the environments matched in the master's top file are downloaded.

This is important to remember, because modules can be manually loaded from any specific environment that environment specific modules will be loaded when a state run is executed.

  Sync Via the saltutil Module

The saltutil module has a number of functions that can be used to sync all or specific dynamic modules. The saltutil module function saltutil.sync_all will sync all module types over to a minion. For more information see: salt.modules.saltutil

FILE SERVER CONFIGURATION

The Salt file server is a high performance file server written in ZeroMQ. It manages large files quickly and with little overhead, and has been optimized to handle small files in an extremely efficient manner.

The Salt file server is an environment aware file server. This means that files can be allocated within many root directories and accessed by specifying both the file path and the environment to search. The individual environments can span across multiple directory roots to create overlays and to allow for files to be organized in many flexible ways.

  Environments

The Salt file server defaults to the mandatory base environment. This environment MUST be defined and is used to download files when no environment is specified.

Environments allow for files and sls data to be logically separated, but environments are not isolated from each other. This allows for logical isolation of environments by the engineer using Salt, but also allows for information to be used in multiple environments.

  Directory Overlay

The environment setting is a list of directories to publish files from. These directories are searched in order to find the specified file and the first file found is returned.

This means that directory data is prioritized based on the order in which they are listed. In the case of this file_roots configuration:

file_roots:
  base:
    - /srv/salt/base
    - /srv/salt/failover

If a file's URI is salt://httpd/httpd.conf, it will first search for the file at /srv/salt/base/httpd/httpd.conf. If the file is found there it will be returned. If the file is not found there, then /srv/salt/failover/httpd/httpd.conf will be used for the source.

This allows for directories to be overlaid and prioritized based on the order they are defined in the configuration.

  Local File Server

New in version 0.9.8.

The file server can be rerouted to run from the minion. This is primarily to enable running Salt states without a Salt master. To use the local file server interface, copy the file server data to the minion and set the file_roots option on the minion to point to the directories copied from the master. Once the minion file_roots option has been set, change the file_client option to local to make sure that the local file server interface is used.

SALT FILE SERVER

Salt comes with a simple file server suitable for distributing files to the Salt minions. The file server is a stateless ZeroMQ server that is built into the Salt master.

The main intent of the Salt file server is to present files for use in the Salt state system. With this said, the Salt file server can be used for any general file transfer from the master to the minions.

  The cp Module

The cp module is the home of minion side file server operations. The cp module is used by the Salt state system, salt-cp and can be used to distribute files presented by the Salt file server.

  Environments

Since the file server is made to work with the Salt state system, it supports environments. The environments are defined in the master config file and when referencing an environment the file specified will be based on the root directory of the environment.

  get_file

The cp.get_file function can be used on the minion to download a file from the master, the syntax looks like this:

# salt '*' cp.get_file salt://vimrc /etc/vimrc

This will instruct all Salt minions to download the vimrc file and copy it to /etc/vimrc

Template rendering can be enabled on both the source and destination file names like so:

# salt '*' cp.get_file "salt://{{grains.os}}/vimrc" /etc/vimrc template=jinja

This example would instruct all Salt minions to download the vimrc from a directory with the same name as their OS grain and copy it to /etc/vimrc

For larger files, the cp.get_file module also supports gzip compression. Because gzip is CPU-intensive, this should only be used in scenarios where the compression ratio is very high (e.g. pretty-printed JSON or YAML files).

Use the gzip named argument to enable it. Valid values are 1..9, where 1 is the lightest compression and 9 the heaviest. 1 uses the least CPU on the master (and minion), 9 uses the most.

# salt '*' cp.get_file salt://vimrc /etc/vimrc gzip=5

Finally, note that by default cp.get_file does not create new destination directories if they do not exist. To change this, use the makedirs argument:

# salt '*' cp.get_file salt://vimrc /etc/vim/vimrc makedirs=True

In this example, /etc/vim/ would be created if it didn't already exist.

  get_dir

The cp.get_dir function can be used on the minion to download an entire directory from the master. The syntax is very similar to get_file:

# salt '*' cp.get_dir salt://etc/apache2 /etc

cp.get_dir supports template rendering and gzip compression arguments just like get_file:

# salt '*' cp.get_dir salt://etc/{{pillar.webserver}} /etc gzip=5 template=jinja

  File Server Client API

A client API is available which allows for modules and applications to be written which make use of the Salt file server.

The file server uses the same authentication and encryption used by the rest of the Salt system for network communication.

  FileClient Class

The FileClient class is used to set up the communication from the minion to the master. When creating a FileClient object the minion configuration needs to be passed in. When using the FileClient from within a minion module the built in __opts__ data can be passed:

import salt.minion
def get_file(path, dest, env='base'):
    '''
    Used to get a single file from the Salt master
    CLI Example:
    salt '*' cp.get_file salt://vimrc /etc/vimrc
    '''
    # Create the FileClient object
    client = salt.minion.FileClient(__opts__)
    # Call get_file
    return client.get_file(path, dest, False, env)

Using the FileClient class outside of a minion module where the __opts__ data is not available, it needs to be generated:

import salt.minion
import salt.config
def get_file(path, dest, env='base'):
    '''
    Used to get a single file from the Salt master
    '''
    # Get the configuration data
    opts = salt.config.minion_config('/etc/salt/minion')
    # Create the FileClient object
    client = salt.minion.FileClient(opts)
    # Call get_file
    return client.get_file(path, dest, False, env)

#####      File Server settings      #####
##########################################
# Salt runs a lightweight file server written in zeromq to deliver files to
# minions. This file server is built into the master daemon and does not
# require a dedicated port.
# The file server works on environments passed to the master, each environment
# can have multiple root directories, the subdirectories in the multiple file
# roots cannot match, otherwise the downloaded files will not be able to be
# reliably ensured. A base environment is required to house the top file.
# Example:
# file_roots:
#   base:
#     - /srv/salt/
#   dev:
#     - /srv/salt/dev/services
#     - /srv/salt/dev/states
#   prod:
#     - /srv/salt/prod/services
#     - /srv/salt/prod/states
#file_roots:
#  base:
#    - /srv/salt
# The hash_type is the hash to use when discovering the hash of a file on
# the master server, the default is md5, but sha1, sha224, sha256, sha384
# and sha512 are also supported.
#hash_type: md5
# The buffer size in the file server can be adjusted here:
#file_buffer_size: 1048576
# A regular expression (or a list of expressions) that will be matched
# against the file path before syncing the modules and states to the minions.
# This includes files affected by the file.recurse state.
# For example, if you manage your custom modules and states in subversion
# and don't want all the '.svn' folders and content synced to your minions,
# you could set this to '/\.svn($|/)'. By default nothing is ignored.
# file_ignore_regex:
#   - '/\.svn($|/)'
#   - '/\.git($|/)'
# A file glob (or list of file globs) that will be matched against the file
# path before syncing the modules and states to the minions. This is similar
# to file_ignore_regex above, but works on globs instead of regex. By default
# nothing is ignored.
# file_ignore_glob:
#   - '*.pyc'
#   - '*/somefolder/*.bak'
# File Server Backend
# Salt supports a modular fileserver backend system, this system allows
# the salt master to link directly to third party systems to gather and
# manage the files available to minions. Multiple backends can be
# configured and will be searched for the requested file in the order in which
# they are defined here. The default setting only enables the standard backend
# "roots" which uses the "file_roots" option.
#fileserver_backend:
#  - roots
# To use multiple backends list them in the order they are searched:
# fileserver_backend:
#   - git
#   - roots
# Git fileserver backend configuration
# When using the git fileserver backend at least one git remote needs to be
# defined. The user running the salt master will need read access to the repo.
# gitfs_remotes:
#   - git://github.com/saltstack/salt-states.git
#   - file:///var/git/saltmaster
# The repos will be searched in order to find the file requested by a client
# and the first repo to have the file will return it.
# When using the git backend branches and tags are translated into salt
# environments.
#####         Pillar settings        #####
##########################################
# Salt Pillars allow for the building of global data that can be made selectively

#pillar_roots:
#  base:
#    - /srv/pillar
# ext_pillar:

#order_masters: False
# If this master will be running a salt syndic daemon, syndic_master tells

#syndic_master: masterofmaster
#####      Peer Publish settings     #####
##########################################
# Salt minions can send commands to other minions, but only if the minion is
# allowed to. By default "Peer Publication" is disabled, and when enabled it
# is enabled for specific minions and specific commands. This allows secure
# compartmentalization of commands based on individual minions.
# The configuration uses regular expressions to match minions and then a list
# of regular expressions to match functions. The following will allow the
# minion authenticated as foo.example.com to execute functions from the test
# and pkg modules.
# peer:
#   foo.example.com:
#       - test.*
#       - pkg.*
#
# This will allow all minions to execute all commands:
# peer:
#   .*:
#       - .*
# This is not recommended, since it would allow anyone who gets root on any
# single minion to instantly have root on all of the minions!
# Minions can also be allowed to execute runners from the salt master.
# Since executing a runner from the minion could be considered a security risk,
# it needs to be enabled. This setting functions just like the peer setting
# except that it opens up runners instead of module functions.
#
# All peer runner support is turned off by default and must be enabled before
# using. This will enable all peer runners for all minions:
#
# peer_run:
#   .*:
#     - .*
#
# To enable just the manage.up runner for the minion foo.example.com:
#
# peer_run:
#   foo.example.com:
#     - manage.up
#####         Logging settings       #####
##########################################
# The location of the master log file
# The master log can be sent to a regular file, local path name, or network
# location. Remote logging works best when configured to use rsyslogd(8) (e.g.:
# ``file:///dev/log``), with rsyslogd(8) configured for network logging. The URI
# format is: <file|udp|tcp>://<host|socketpath>:<port-if-required>/<log-facility>
#log_file: /var/log/salt/master
#log_file: file:///dev/log
#log_file: udp://loghost:10514
#log_file: /var/log/salt/master
#key_logfile: /var/log/salt/key
# The level of messages to send to the console.
# One of 'garbage', 'trace', 'debug', info', 'warning', 'error', 'critical'.
#log_level: warning
# The level of messages to send to the log file.
# One of 'garbage', 'trace', 'debug', info', 'warning', 'error', 'critical'.
#log_level_logfile: warning
# The date and time format used in log messages. Allowed date/time formating
# can be seen here: http://docs.python.org/library/time.html#time.strftime
#log_datefmt: '%H:%M:%S'
#log_datefmt_logfile: '%Y-%m-%d %H:%M:%S'
# The format of the console logging messages. Allowed formatting options can
# be seen here: http://docs.python.org/library/logging.html#logrecord-attributes
#log_fmt_console: '[%(levelname)-8s] %(message)s'
#log_fmt_logfile: '%(asctime)s,%(msecs)03.0f [%(name)-17s][%(levelname)-8s] %(message)s'
# This can be used to control logging levels more specificically.  This
# example sets the main salt library at the 'warning' level, but sets
# 'salt.modules' to log at the 'debug' level:
#   log_granular_levels:
#     'salt': 'warning',
#     'salt.modules': 'debug'
#
#log_granular_levels: {}
#####         Node Groups           #####
##########################################
# Node groups allow for logical groupings of minion nodes.
# A group consists of a group name and a compound target.

##########################################
# Per default the minion will automatically include all config files
# from minion.d/*.conf (minion.d is a directory in the same directory
# as the main minion config file).
#default_include: minion.d/*.conf
# Set the location of the salt master server, if the master server cannot be
# resolved, then the minion will fail to start.
#master: salt
# Set the number of seconds to wait before attempting to resolve
# the master hostname if name resolution fails. Defaults to 30 seconds.
# Set to zero if the minion should shutdown and not retry.
# retry_dns: 30
# Set the port used by the master reply and authentication server
#master_port: 4506
# The user to run salt
#user: root
# Specify the location of the daemon process ID file
#pidfile: /var/run/salt-minion.pid
# The root directory prepended to these options: pki_dir, cachedir, log_file,
# sock_dir, pidfile.
#root_dir: /
# The directory to store the pki information in
#pki_dir: /etc/salt/pki/minion
# Explicitly declare the id for this minion to use, if left commented the id
# will be the hostname as returned by the python call: socket.getfqdn()
# Since salt uses detached ids it is possible to run multiple minions on the
# same machine but with different ids, this can be useful for salt compute
# clusters.
#id:
# Append a domain to a hostname in the event that it does not exist.  This is
# useful for systems where socket.getfqdn() does not actually result in a
# FQDN (for instance, Solaris).
#append_domain:
# Custom static grains for this minion can be specified here and used in SLS
# files just like all other grains. This example sets 4 custom grains, with

# set cache_jobs to True
#cache_jobs: False
# set the directory used to hold unix sockets
#sock_dir: /var/run/salt/minion
# Set the default outputter used by the salt-call command. The default is

# /etc/ssh/sshd_config:
#   file.managed:
#     - source: salt://ssh/sshd_config
#       - backup: minion
#
#backup_mode: minion
# When waiting for a master to accept the minion's public key, salt will
# continuously attempt to reconnect until successful. This is the time, in
# seconds, between those reconnection attempts.
#acceptance_wait_time: 10
# The loop_interval sets how long in seconds the minion will wait between
# evaluating the scheduler and running cleanup tasks. This defaults to a
# sane 60 seconds, but if the minion scheduler needs to be evaluated more
# often lower this value
#loop_interval: 60
# When healing, a dns_check is run. This is to make sure that the originally
# resolved dns has not changed. If this is something that does not happen in
# your environment, set this value to False.
#dns_check: True
# Windows platforms lack posix IPC and must rely on slower TCP based inter-
# process communications. Set ipc_mode to 'tcp' on such systems
#ipc_mode: ipc
#
# Overwrite the default tcp ports used by the minion when in tcp mode
#tcp_pub_port: 4510
#tcp_pull_port: 4511
# The minion can include configuration from other files. To enable this,
# pass a list of paths to this option. The paths can be either relative or
# absolute; if relative, they are considered to be relative to the directory
# the main minion configuration file lives in (this file). Paths can make use
# of shell-style globbing. If no files are matched by a path passed to this
# option then the minion will log a warning message.
#
#
# Include a config file from some other path:
# include: /etc/salt/extra_config
#
# Include config from several files and directories:
# include:
#  - /etc/salt/extra_config

#####    State Management Settings    #####
###########################################
# The state management system executes all of the state templates on the minion

#autoload_dynamic_modules: True
#
# clean_dynamic_modules keeps the dynamic modules on the minion in sync with

# enabled and can be disabled by changing this value to False
#clean_dynamic_modules: True
#
# Normally the minion is not isolated to any single environment on the master

#####     File Directory Settings    #####
##########################################
# The Salt Minion can redirect all file server operations to a local directory,
# this allows for the same state tree that is on the master to be used if
# copied completely onto the minion. This is a literal copy of the settings on
# the master but used to reference a local directory on the minion.
# Set the file client, the client defaults to looking on the master server for
# files, but can be directed to look at the local file directory setting
# defined below by setting it to local.
#file_client: remote
# The file directory works on environments passed to the minion, each environment
# can have multiple root directories, the subdirectories in the multiple file
# roots cannot match, otherwise the downloaded files will not be able to be
# reliably ensured. A base environment is required to house the top file.
# Example:
# file_roots:
#   base:
#     - /srv/salt/
#   dev:
#     - /srv/salt/dev/services
#     - /srv/salt/dev/states
#   prod:

#     - /srv/salt/prod/states
#
# Default:
#file_roots:
#  base:
#    - /srv/salt
# The hash_type is the hash to use when discovering the hash of a file in
# the minion directory, the default is md5, but sha1, sha224, sha256, sha384
# and sha512 are also supported.
#hash_type: md5
# The Salt pillar is searched for locally if file_client is set to local. If
# this is the case, and pillar data is defined, then the pillar_roots need to
# also be configured on the minion:

CONFIGURING THE SALT MASTER

The Salt system is amazingly simple and easy to configure, the two components of the Salt system each have a respective configuration file. The salt-master is configured via the master configuration file, and the salt-minion is configured via the minion configuration file.

See also

    example master configuration file

The configuration file for the salt-master is located at /etc/salt/master. The available options are as follows:

  Primary Master Configuration

  interface

Default: 0.0.0.0 (all interfaces)

The local interface to bind to.

interface: 192.168.0.1

  publish_port

Default: 4505

The network port to set up the publication interface

publish_port: 4505

  user

Default: root

The user to run the Salt processes

user: root

  max_open_files

Default: max_open_files

Each minion connecting to the master uses AT LEAST one file descriptor, the master subscription connection. If enough minions connect you might start seeing on the console(and then salt-master crashes):

Too many open files (tcp_listener.cpp:335)
Aborted (core dumped)

By default this value will be the one of ulimit -Hn, i.e., the hard limit for max open files.

If you wish to set a different value than the default one, uncomment and configure this setting. Remember that this value CANNOT be higher than the hard limit. Raising the hard limit depends on your OS and/or distribution, a good way to find the limit is to search the internet for(for example):

raise max open files hard limit debian

max_open_files: 100000

  worker_threads

Default: 5

The number of threads to start for receiving commands and replies from minions. If minions are stalling on replies because you have many minions, raise the worker_threads value.

worker_threads: 5

  ret_port

Default: 4506

The port used by the return server, this is the server used by Salt to receive execution returns and command executions.

ret_port: 4506

  pidfile

Default: /var/run/salt-master.pid

Specify the location of the master pidfile

pidfile: /var/run/salt-master.pid

  root_dir

Default: /

The system root directory to operate from, change this to make Salt run from an alternative root

root_dir: /

  pki_dir

Default: /etc/salt/pki

The directory to store the pki authentication keys.

pki_dir: /etc/salt/pki

  cachedir

Default: /var/cache/salt

The location used to store cache information, particularly the job information for executed salt commands.

cachedir: /var/cache/salt

  keep_jobs

Default: 24

Set the number of hours to keep old job information

  job_cache

Default: True

The master maintains a job cache, while this is a great addition it can be a burden on the master for larger deployments (over 5000 minions). Disabling the job cache will make previously executed jobs unavailable to the jobs system and is not generally recommended. Normally it is wise to make sure the master has access to a faster IO system or a tmpfs is mounted to the jobs dir

  ext_job_cache

Default: ''

Used to specify a default returner for all minions, when this option is set the specified returner needs to be properly configured and the minions will always default to sending returns to this returner. This will also disable the local job cache on the master

ext_job_cache: redis

  sock_dir

Default:: /tmp/salt-unix

Set the location to use for creating Unix sockets for master process communication

  Master Security Settings

  open_mode

Default: False

Open mode is a dangerous security feature. One problem encountered with pki authentication systems is that keys can become "mixed up" and authentication begins to fail. Open mode turns off authentication and tells the master to accept all authentication. This will clean up the pki keys received from the minions. Open mode should not be turned on for general use. Open mode should only be used for a short period of time to clean up pki keys. To turn on open mode set this value to True.

open_mode: False

  auto_accept

Default: False

Enable auto_accept. This setting will automatically accept all incoming public keys from the minions

auto_accept: False

  autosign_file

Default not defined

If the autosign_file is specified incoming keys specified in the autosign_file will be automatically accepted. Regular expressions as well as globbing can be used. This is insecure!

  client_acl

Default: {}

Enable user accounts on the master to execute specific modules. These modules can be expressed as regular expressions

client_acl:
  fred:
    - test.ping
    - pkg.*

  Master Module Management

  runner_dirs

Default: []

Set additional directories to search for runner modules

  cython_enable

Default: False

Set to true to enable cython modules (.pyx files) to be compiled on the fly on the Salt master

cython_enable: False

  Master State System Settings

  state_verbose

Default: False

state_verbose allows for the data returned from the minion to be more verbose. Normally only states that fail or states that have changes are returned, but setting state_verbose to True will return all states that were checked

state_verbose: True

  state_output

Default: full

The state_output setting changes if the output is the full multi line output for each changed state if set to 'full', but if set to 'terse' the output will be shortened to a single line.

state_output: full

  state_top

Default: top.sls

The state system uses a "top" file to tell the minions what environment to use and what modules to use. The state_top file is defined relative to the root of the base environment

state_top: top.sls

  external_nodes

Default: None

The external_nodes option allows Salt to gather data that would normally be placed in a top file from and external node controller. The external_nodes option is the executable that will return the ENC data. Remember that Salt will look for external nodes AND top files and combine the results if both are enabled and available!

external_nodes: cobbler-ext-nodes

  renderer

Default: yaml_jinja

The renderer to use on the minions to render the state data

renderer: yaml_jinja

  failhard

Default:: False

Set the global failhard flag, this informs all states to stop running states at the moment a single state fails

failhard: False

  test

Default:: False

Set all state calls to only test if they are going to actually make changes or just post what changes are going to be made

test: False

  Master File Server Settings

  file_roots

Default: base: [/srv/salt]

Salt runs a lightweight file server written in ZeroMQ to deliver files to minions. This file server is built into the master daemon and does not require a dedicated port.

The file server works on environments passed to the master. Each environment can have multiple root directories. The subdirectories in the multiple file roots cannot match, otherwise the downloaded files will not be able to be reliably ensured. A base environment is required to house the top file. Example:

file_roots:
  base:
    - /srv/salt
  dev:
    - /srv/salt/dev/services
    - /srv/salt/dev/states
  prod:
    - /srv/salt/prod/services
    - /srv/salt/prod/states

base:
  - /srv/salt

  hash_type

Default: md5

The hash_type is the hash to use when discovering the hash of a file on the master server, the default is md5, but sha1, sha224, sha256, sha384 and sha512 are also supported.

hash_type: md5

  file_buffer_size

Default: 1048576

The buffer size in the file server in bytes

file_buffer_size: 1048576

  Pillar Configuration

  pillar_roots

Set the environments and directories used to hold pillar sls data. This configuration is the same as file_roots:

Default: base: [/srv/pillar]

pillar_roots:
  base:
    - /srv/pillar/
  dev:
    - /srv/pillar/dev/
  prod:
    - /srv/pillar/prod/

base:
  - /srv/pillar

  ext_pillar

The ext_pillar option allows for any number of external pillar interfaces to be called when populating pillar data. The configuration is based on ext_pillar functions. The available ext_pillar functions are: hiera, cmd_yaml. By default the ext_pillar interface is not configured to run.

Default:: None

ext_pillar:
  - hiera: /etc/hiera.yaml
  - cmd_yaml: cat /etc/salt/yaml

There are additional details at salt-pillars

  Syndic Server Settings

A Salt syndic is a Salt master used to pass commands from a higher Salt master to minions below the syndic. Using the syndic is simple. If this is a master that will have syndic servers(s) below it, set the "order_masters" setting to True. If this is a master that will be running a syndic daemon for passthrough the "syndic_master" setting needs to be set to the location of the master server

  order_masters

Default: False

Extra data needs to be sent with publications if the master is controlling a lower level master via a syndic minion. If this is the case the order_masters value must be set to True

order_masters: False

  syndic_master

Default: None

If this master will be running a salt-syndic to connect to a higher level master, specify the higher level master with this configuration value

syndic_master: masterofmasters

  Peer Publish Settings

Salt minions can send commands to other minions, but only if the minion is allowed to. By default "Peer Publication" is disabled, and when enabled it is enabled for specific minions and specific commands. This allows secure compartmentalization of commands based on individual minions.

  peer

Default: {}

The configuration uses regular expressions to match minions and then a list of regular expressions to match functions. The following will allow the minion authenticated as foo.example.com to execute functions from the test and pkg modules

peer:
  foo.example.com:
      - test.*
      - pkg.*

This will allow all minions to execute all commands:

peer:
  .*:
      - .*

This is not recommended, since it would allow anyone who gets root on any single minion to instantly have root on all of the minions!

  peer_run

Default: {}

The peer_run option is used to open up runners on the master to access from the minions. The peer_run configuration matches the format of the peer configuration.

The following example would allow foo.example.com to execute the manage.up runner:

peer_run:
  foo.example.com:
      - manage.up

  Node Groups

Default: {}

Node groups allow for logical groupings of minion nodes. A group consists of a group name and a compound target.

nodegroups:
  group1: 'L@foo.domain.com,bar.domain.com,baz.domain.com and bl*.domain.com'
  group2: 'G@os:Debian and foo.domain.com'

  Master Logging Settings

  log_file

Default: /var/log/salt/master

The master log can be sent to a regular file, local path name, or network location. Remote logging works best when configured to use rsyslogd(8) (e.g.: file:///dev/log), with rsyslogd(8) configured for network logging. The format for remote addresses is: <file|udp|tcp>://<host|socketpath>:<port-if-required>/<log-facility>. Examples:

log_file: /var/log/salt/master

log_file: file:///dev/log

log_file: udp://loghost:10514

  log_level

Default: warning

The level of messages to send to the console. One of 'garbage', 'trace', 'debug', info', 'warning', 'error', 'critical'.

log_level: warning

Default: warning

The level of messages to send to the log file. One of 'garbage', 'trace', 'debug', info', 'warning', 'error', 'critical'.

log_level_logfile: warning

  log_datefmt

Default: %H:%M:%S

The date and time format used in console log messages. Allowed date/time formatting can be seen on http://docs.python.org/library/time.html#time.strftime

log_datefmt: '%H:%M:%S'

  log_datefmt_logfile

The date and time format used in log file messages. Allowed date/time formatting can be seen on http://docs.python.org/library/time.html#time.strftime

log_datefmt_logfile: '%Y-%m-%d %H:%M:%S'

  log_fmt_console

Default: [%(levelname)-8s] %(message)s

The format of the console logging messages. Allowed formatting options can be seen on http://docs.python.org/library/logging.html#logrecord-attributes

log_fmt_console: '[%(levelname)-8s] %(message)s'

  log_fmt_logfile

Default: %(asctime)s,%(msecs)03.0f [%(name)-17s][%(levelname)-8s] %(message)s

The format of the log file logging messages. Allowed formatting options can be seen on http://docs.python.org/library/logging.html#logrecord-attributes

log_fmt_logfile: '%(asctime)s,%(msecs)03.0f [%(name)-17s][%(levelname)-8s] %(message)s'

  log_granular_levels

Default: {}

This can be used to control logging levels more specifically. The example sets the main salt library at the 'warning' level, but sets 'salt.modules' to log at the 'debug' level:

log_granular_levels:
  'salt': 'warning',
  'salt.modules': 'debug'

  default_include

Default: master.d/*.conf

The master can include configuration from other files. Per default the master will automatically include all config files from master.d/*.conf where master.d is relative to the directory of the master configuration file.

CONFIGURING THE SALT MINION

The Salt system is amazingly simple and easy to configure, the two components of the Salt system each have a respective configuration file. The salt-master is configured via the master configuration file, and the salt-minion is configured via the minion configuration file.

See also

    example minion configuration file

The Salt Minion configuration is very simple, typically the only value that needs to be set is the master value so the minion can find its master.

  Minion Primary Configuration

  master

Default: salt

The hostname or ipv4 of the master.

master: salt

  master_port

Default: 4506

The port of the master ret server, this needs to coincide with the ret_port option on the Salt master.

master_port: 4506

Default: root

The user to run the Salt processes

user: root

  pidfile

Default: /var/run/salt-minion.pid

The location of the daemon's process ID file

The directory used to store the minion's public and private keys.

pki_dir: /etc/salt/pki

  id

Default: hostname (as returned by the Python call: socket.getfqdn())

Explicitly declare the id for this minion to use, if left commented the id will be the hostname as returned by the Python call: socket.getfqdn() Since Salt uses detached ids it is possible to run multiple minions on the same machine but with different ids, this can be useful for Salt compute clusters.

id: foo.bar.com

  append_domain

Default: None

Append a domain to a hostname in the event that it does not exist. This is useful for systems where socket.getfqdn() does not actually result in a FQDN (for instance, Solaris).

append_domain: foo.org

  cachedir

Default: /var/cache/salt

The location for minion cache data.

cachedir: /var/cache/salt

  verify_env

Default: True

Verify and set permissions on configuration directories at startup.

verify_env: True

  cache_jobs

Default: False

The minion can locally cache the return data from jobs sent to it, this can be a good way to keep track of the minion side of the jobs the minion has executed. By default this feature is disabled, to enable set cache_jobs to True.

cache_jobs: False

  sock_dir

Default: /var/run/salt/minion

The directory where Unix sockets will be kept.

sock_dir: /var/run/salt/minion

  backup_mode

Default: []

Backup files replaced by file.managed and file.recurse under cachedir.

Default: 10

The number of seconds to wait until attempting to re-authenticate with the master.

acceptance_wait_time: 10

  dns_check

Default: True

When healing, a dns_check is run. This is to make sure that the originally resolved dns has not changed. If this is something that does not happen in your environment, set this value to False.

dns_check: True

  ipc_mode

Default: ipc

Windows platforms lack POSIX IPC and must rely on slower TCP based inter- process communications. Set ipc_mode to tcp on such systems.

ipc_mode: ipc

  tcp_pub_port

Default: 4510

Publish port used when ipc_mode is set to tcp.

tcp_pub_port: 4510

  tcp_pull_port

Default: 4511

Pull port used when ipc_mode is set to tcp.

tcp_pull_port: 4511

  Minion Module Management

  disable_modules

Default: [] (all modules are enabled by default)

The event may occur in which the administrator desires that a minion should not be able to execute a certain module. The sys module is built into the minion and cannot be disabled.

This setting can also tune the minion, as all modules are loaded into ram disabling modules will lover the minion's ram footprint.

disable_modules:
  - test
  - solr

  cython_enable

Default: False

Set this value to true to enable auto-loading and compiling of .pyx modules, This setting requires that gcc and cython are installed on the minion

cython_enable: False

  providers

Default: (empty)

A module provider can be statically overwritten or extended for the minion via the providers option. This can be done on an individual basis in an SLS file, or globally here in the minion config, like below.

providers:

  service: systemd

  State Management Settings

  renderer

Default: yaml_jinja

The default renderer used for local state executions

renderer: yaml_jinja

  state_verbose

state_verbose allows for the data returned from the minion to be more verbose. Normally only states that fail or states that have changes are returned, but setting state_verbose to True will return all states that were checked

state_verbose: True

  state_output

Default: full

The state_output setting changes if the output is the full multi line output for each changed state if set to 'full', but if set to 'terse' the output will be shortened to a single line.

Default: True

autoload_dynamic_modules Turns on automatic loading of modules found in the environments on the master. This is turned on by default, to turn of auto-loading modules when states run set this value to False

autoload_dynamic_modules: True

Default: True

clean_dynamic_modules keeps the dynamic modules on the minion in sync with the dynamic modules on the master, this means that if a dynamic module is not on the master it will be deleted from the minion. By default this is enabled and can be disabled by changing this value to False

clean_dynamic_modules: True

  environment

Default: None

Normally the minion is not isolated to any single environment on the master when running states, but the environment can be isolated on the minion side by statically setting it. Remember that the recommended way to manage environments is to isolate via the top file.

environment: None

  Security Settings

  open_mode

Default: False

Open mode can be used to clean out the PKI key received from the Salt master, turn on open mode, restart the minion, then turn off open mode and restart the minion to clean the keys.

open_mode: False

  Thread Settings

Default: True

Disable multiprocessing support by default when a minion receives a publication a new process is spawned and the command is executed therein.

multiprocessing: True

  Minion Logging Settings

  log_file

Default: /var/log/salt/minion

The minion log can be sent to a regular file, local path name, or network location. Remote logging works best when configured to use rsyslogd(8) (e.g.: file:///dev/log), with rsyslogd(8) configured for network logging. The format for remote addresses is: <file|udp|tcp>://<host|socketpath>:<port-if-required>/<log-facility>. Examples:

log_fmt_logfile: '%(asctime)s,%(msecs)03.0f [%(name)-17s][%(levelname)-8s] %(message)s'

  log_granular_levels

Default: {}

This can be used to control logging levels more specifically. This example sets the main salt library at the 'warning' level, but sets 'salt.modules' to log at the 'debug' level:

log_granular_levels:
  'salt': 'warning',
  'salt.modules': 'debug'

  default_include

Default: minion.d/*.conf

The minion can include configuration from other files. Per default the minion will automatically include all config files from minion.d/*.conf where minion.d is relative to the directory of the minion configuration file.

  include

Default: not defined

The minion can include configuration from other files. To enable this, pass a list of paths to this option. The paths can be either relative or absolute; if relative, they are considered to be relative to the directory the main minion configuration file lives in. Paths can make use of shell-style globbing. If no files are matched by a path passed to this option then the minion will log a warning message.

# Include files from a minion.d directory in the same
# directory as the minion config file
include: minion.d/*
# Include a single extra file into the configuration
include: /etc/roles/webserver
# Include several files and the minion.d directory
include:
  - extra_config
  - minion.d/*
  - /etc/roles/webserver

  Frozen Build Update Settings

These options control how salt.modules.saltutil.update() works with esky frozen apps. For more information look at https://github.com/cloudmatrix/esky/.

  update_url

Default: False (Update feature is disabled)

The url to use when looking for application updates. Esky depends on directory listings to search for new versions. A webserver running on your Master is a good starting point for most setups.

update_url: 'http://salt.example.com/minion-updates'

  update_restart_services

Default: [] (service restarting on update is disabled)

A list of services to restart when the minion software is updated. This would typically just be a list containing the minion's service name, but you may have other services that need to go with it.

update_restart_services: ['salt-minion']

SALT CODE AND INTERNALS

Reference documentation on Salt's internal code.

NETWORK TOPOLOGY

Salt is based on a powerful, asynchronous, network topology using ZeroMQ. Many ZeroMQ systems are in place to enable communication. The central idea is to have the fastest communication possible.

  Servers

The Salt Master runs 2 network services. First is the ZeroMQ PUB system. This service by default runs on port 4505 and can be configured via the publish_port option in the master configuration.

Second is the ZeroMQ REP system. This is a separate interface used for all bi-directional communication with minions. By default this system binds to port 4506 and can be configured via the ret_port option in the master.

  PUB/SUB

The commands sent out via the salt client are broadcast out to the minions via ZeroMQ PUB/SUB. This is done by allowing the minions to maintain a connection back to the Salt Master and then all connections are informed to download the command data at once. The command data is kept extremely small (usually less than 1K) so it is not a burden on the network.

  Return

The PUB/SUB system is a one way communication, so once a publish is sent out the PUB interface on the master has no further communication with the minion. The minion, after running the command, then sends the command's return data back to the master via the ret_port.

WINDOWS SOFTWARE REPOSITORY

The Salt Windows Software Repository provides a package manager and software repository similar to what is provided by yum and apt on Linux.

By default, the Windows software repository is found at /srv/salt/win/repo Each piece of software should have its own directory which contains the installers and a package definition file. This package definition file is a YAML file named init.sls.

The package definition file should look similar to this example for Firefox: /srv/salt/win/repo/firefox/init.sls

firefox:
  17.0.1:
    installer: 'salt://win/repo/firefox/English/Firefox Setup 17.0.1.exe'
    full_name: Mozilla Firefox 17.0.1 (x86 en-US)
    locale: en_US
    reboot: False
    install_flags: ' -ms'
    uninstaller: '%ProgramFiles(x86)%/Mozilla Firefox/uninstall/helper.exe'
    uninstall_flags: ' /S'
  16.0.2:
    installer: 'salt://win/repo/firefox/English/Firefox Setup 16.0.2.exe'
    full_name: Mozilla Firefox 16.0.2 (x86 en-US)
    locale: en_US
    reboot: False
    install_flags: ' -ms'
    uninstaller: '%ProgramFiles(x86)%/Mozilla Firefox/uninstall/helper.exe'
    uninstall_flags: ' /S'
  15.0.1:
    installer: 'salt://win/repo/firefox/English/Firefox Setup 15.0.1.exe'
    full_name: Mozilla Firefox 15.0.1 (x86 en-US)
    locale: en_US
    reboot: False
    install_flags: ' -ms'
    uninstaller: '%ProgramFiles(x86)%/Mozilla Firefox/uninstall/helper.exe'
    uninstall_flags: ' /S'

Add msiexec: True if using an MSI installer requiring the use of msiexec /i to install and msiexec /x to uninstall. /srv/salt/win/repo/7zip/init.sls

7zip:
  9.20:
    installer: salt://win/repo/7zip/7z920-x64.msi
    full_name: 7zip 9.22
    reboot: False
    install_flags: ' /q '
    msiexec: True
    uninstaller: salt://win/repo/7zip/7z920-x64.msi
    uninstall_flags: ' /qn'

  Generate Repo Cache File

Once the sls file has been created, generate the repository cache file with the winrepo runner:

$ salt-run winrepo.genrepo

Then update the repository cache file on your minions, exactly how it's done for the Linux package managers:

$ salt \* pkg.refresh_db

  Install Windows Software

Now you can query the available version of Firefox using the Salt pkg module.

$ salt \* pkg.available_version firefox
{'davewindows': {'15.0.1': 'Mozilla Firefox 15.0.1 (x86 en-US)',
                 '16.0.2': 'Mozilla Firefox 16.0.2 (x86 en-US)',
                 '17.0.1': 'Mozilla Firefox 17.0.1 (x86 en-US)'}}

As you can see, there are three versions of Firefox available for installation.

$ salt \* pkg.install firefox

The above line will install the latest version of firefox.

$ salt \* pkg.install firefox version=16.0.2

The above line will install version 16.0.2 of Firefox.

This first release requires you uninstall an application and then install a newer version in order to accomplish an upgrade. This will be fixed very soon.

  Uninstall Windows Software

Uninstall software using the pkg module:

$ salt \* pkg.remove firefox

  Git Hosted Repo

Windows software package definitions can also be hosted in one or more git repositories. The default repo is one hosted on Github.com by SaltStack, which includes package definitions for open source software. This repo points to the HTTP or ftp locations of the installer files. Anyone is welcome to send a pull request to this repo to add new package definitions. Browse the repo here: https://github.com/saltstack/salt-winrepo .

Configure which git repos the master can search for package definitions by modifying or extending the win_gitrepos configuration option list in the master config.

Checkout each git repo in win_gitrepos, compile your package repository cache, and then refresh each minion's package cache:

$ salt-run winrepo.update_git_repos
$ salt-run winrepo.genrepo
$ salt \* pkg.refresh_db

COMMAND LINE REFERENCE

Salt can be controlled by a command line client by the root user on the Salt master. The Salt command line client uses the Salt client API to communicate with the Salt master server. The Salt client is straightforward and simple to use.

Using the Salt client commands can be easily sent to the minions.

Each of these commands accepts an explicit --config option to point to either the master or minion configuration file. If this option is not provided and the default configuration file does not exist then Salt falls back to use the environment variables SALT_MASTER_CONFIG and SALT_MINION_CONFIG.

  Using the Salt Command

The Salt command needs a few components to send information to the Salt minions. The target minions need to be defined, the function to call and any arguments the function requires.

  Defining the Target Minions

The first argument passed to salt, defines the target minions, the target minions are accessed via their hostname. The default target type is a bash glob:

salt \*foo.com sys.doc

Salt can also define the target minions with regular expressions:

salt -E '.*' cmd.run 'ls -l | grep foo'

Or to explicitly list hosts, salt can take a list:

salt -L foo.bar.baz,quo.qux cmd.run 'ps aux | grep foo'

  More Powerful Targets

The simple target specifications, glob, regex and list will cover many use cases, and for some will cover all use cases, but more powerful options exist.

  Targeting with Grains

The Grains interface was built into Salt to allow minions to be targeted by system properties. So minions running on a particular operating system can be called to execute a function, or a specific kernel.

Calling via a grain is done by passing the -G option to salt, specifying a grain and a regular expression to match the value of the grain.

salt -G 'os:Fedora' test.ping

Will return True from all of the minions running Fedora.

To discover what grains are available and what the values are, execute the grains.item salt function:

salt '*' grains.items

  Targeting with Executions

As of 0.8.8 targeting with executions is still under heavy development and this documentation is written to reference the behavior of execution matching in the future.

Execution matching allows for a primary function to be executed, and then based on the return of the primary function the main function is executed.

Execution matching allows for matching minions based on any arbitrary running data on the minions.

  Compound Targeting

New in version 0.9.5.

Multiple target interfaces can be used in conjunction to determine the command targets. These targets can then be combined using and or or statements. This is well defined with an example:

salt -C 'G@os:Debian and webser* or E@db.*' test.ping

In this example any minion who's id starts with webser and is running Debian, or any minion who's id starts with db will be matched.

The type of matcher defaults to glob, but can be specified with the corresponding letter followed by the @ symbol. In the above example a grain is used with G@ as well as a regular expression with E@. The webser* target does not need to be prefaced with a target type specifier because it is a glob.

  Node Group Targeting

New in version 0.9.5.

Often the convenience of having a predefined group of minions to execute targets on is desired. This can be accomplished with the new nodegroups feature. Nodegroups allow for predefined compound targets to be declared in the master configuration file:

nodegroups:
  group1: 'L@foo.domain.com,bar.domain.com,baz.domain.com and bl*.domain.com'
  group2: 'G@os:Debian and foo.domain.com'

  Calling the Function

The function to call on the specified target is placed after the target specification.

New in version 0.9.8.

Functions may also accept arguments, space-delimited:

salt '*' cmd.exec_code python 'import sys; print sys.version'

Optional, keyword arguments are also supported:

salt '*' pip.install salt timeout=5 upgrade=True

They are always in the form of kwarg=argument.

  Finding available minion functions

The Salt functions are self documenting, all of the function documentation can be retried from the minions via the sys.doc() function:

salt '*' sys.doc

  Compound Command Execution

If a series of commands needs to be sent to a single target specification then the commands can be sent in a single publish. This can make gathering groups of information faster, and lowers the stress on the network for repeated commands.

Compound command execution works by sending a list of functions and arguments instead of sending a single function and argument. The functions are executed on the minion in the order they are defined on the command line, and then the data from all of the commands are returned in a dictionary. This means that the set of commands are called in a predictable way, and the returned data can be easily interpreted.

Executing compound commands if done by passing a comma delimited list of functions, followed by a comma delimited list of arguments:

salt '*' cmd.run,test.ping,test.echo 'cat /proc/cpuinfo',,foo

The trick to look out for here, is that if a function is being passed no arguments, then there needs to be a placeholder for the absent arguments. This is why in the above example, there are two commas right next to each other. test.ping takes no arguments, so we need to add another comma, otherwise Salt would attempt to pass "foo" to test.ping.

SALT

  Synopsis
salt '*' [ options ] sys.doc

salt -E '.*' [ options ] sys.doc cmd

salt -G 'os:Arch.*' [ options ] test.ping

salt -C 'G@os:Arch.* and webserv* or G@kernel:FreeBSD' [ options ] test.ping

  Description

Salt allows for commands to be executed across a swath of remote systems in parallel. This means that remote systems can be both controlled and queried with ease.

  Options

-h, --help
    Print a usage message briefly summarizing these command-line options

-t TIMEOUT, --timeout=TIMEOUT
    The timeout in seconds to wait for replies from the Salt minions. The timeout number specifies how long the command line client will wait to query the minions and check on running jobs.

-s, --static
    By default as of version 0.9.8 the salt command returns data to the console as it is received from minions, but previous releases would return data only after all data was received. To only return the data with a hard timeout and after all minions have returned then use the static option.

--async
    Instead of waiting for the job to run on minions only print the jod id of the started execution and complete.

-b BATCH, --batch-size=BATCH
    Instead of executing on all targeted minions at once, execute on a progressive set of minions. This option takes an argument in the form of an explicit number of minions to execute at once, or a percentage of minions to execute on.

-a EAUTH, --auth=EAUTH
    Pass in an external authentication medium to validate against. The credentials will be prompted for. Can be used with the -T option.

-T, --make-token
    Used in conjunction with the -a option. This creates a token that allows for the authenticated user to send commands without needing to re-authenticate.

--version
    Print the version of Salt that is running.

--versions-report
    Show program's dependencies version number and exit

-E, --pcre
    The target expression will be interpreted as a pcre regular expression rather than a shell glob.

-L, --list
    The target expression will be interpreted as a comma delimited list, example: server1.foo.bar,server2.foo.bar,example7.quo.qux

-G, --grain
    The target expression matches values returned by the Salt grains system on the minions. The target expression is in the format of '<grain value>:<glob expression>'; example: 'os:Arch*'

    This was changed in version 0.9.8 to accept glob expressions instead of regular expression. To use regular expression matching with grains use the --grain-pcre option.

--grain-pcre
    The target expression matches values returned by the Salt grains system on the minions. The target expression is in the format of '<grain value>:< regular expression>'; example: 'os:Arch.*'

-C, --compound
    Utilize many target definitions to make the call very granular. This option takes a group of targets separated by and or or. The default matcher is a glob as usual, if something other than a glob is used preface it with the letter denoting the type, example: 'webserv* and G@os:Debian or E@db*' make sure that the compound target is encapsulated in quotes.

-X, --exsel
    Instead of using shell globs use the return code of a function.

-N, --nodegroup
    Use a predefined compound target defined in the Salt master configuration file.

-I, --pillar
    Instead of using shell globs to evaluate the target use a pillar value to identify targets, the syntax for the target is the pillar key followed by a glob expression: "role:production*"

-S, --ipcidr
    Match based on Subnet (CIDR notation) or IPv4 address.

-R, --range
    Instead of using shell globs to evaluate the target use a range expression to identify targets. Range expressions look like %cluster.

    Using the Range option requires that a range server is set up and the location of the range server is referenced in the master configuration file.

--return
    Chose an alternative returner to call on the minion, if an alternative returner is used then the return will not come back to the command line but will be sent to the specified return system.

-c CONFIG_DIR, --config-dir=CONFIG_dir
    The location of the Salt configuration directory, this directory contains the configuration files for Salt master and minions. The default location on most systems is /etc/salt.

-v VERBOSE, --verbose
    Turn on verbosity for the salt call, this will cause the salt command to print out extra data like the job id.

-d, --doc, --documentation
    Return the documentation for the module functions available on the minions

--out
    Pass in an alternative outputter to display the return of data. This outputter can be any of the available outputters: grains, highstate, json, key, overstatestage, pprint, raw, txt, yaml Some outputters are formatted only for data returned from specific functions, for instance the grains outputter will not work for non grains data. If an outputter is used that does not support the data passed into it, then Salt will fall back on the pprint outputter and display the return data using the python pprint library.

--out-indent OUTPUT_INDENT, --output-indent OUTPUT_INDENT
    Print the output indented by the provided value in spaces. Negative values disables indentation. Only applicable in outputters that support indentation.

--no-color
    Disable all colored output

RELEASE NOTES AND UPGRADE INSTRUCTIONS

  Salt 0.10.0 Release Notes

0.10.0 has arrived! This release comes with MANY bug fixes, and new capabilities which greatly enhance performance and reliability. This release is primarily a bug fix release with many new tests and many repaired bugs. This release also introduces a few new key features which were brought in primarily to repair bugs and some limitations found in some of the components of the original architecture.

  Major Features

  Event System

The Salt Master now comes equipped with a new event system. This event system has replaced some of the back end of the Salt client and offers the beginning of a system which will make plugging external applications into Salt. The event system relies on a local ZeroMQ publish socket and other processes can connect to this socket and listen for events. The new events can be easily managed via Salt's event library.

  Unprivileged User Updates

Some enhancements have been added to Salt for running as a user other than root. These new additions should make switching the user that the Salt Master is running as very painless, simply change the user option in the master configuration and restart the master, Salt will take care of all of the particulars for you.

  Peer Runner Execution

Salt has long had the peer communication system used to allow minions to send commands via the salt master. 0.10.0 adds a new capability here, now the master can be configured to allow for minions to execute Salt runners via the peer_run option in the salt master configuration.

  YAML Parsing Updates

In the past the YAML parser for sls files would return the incorrect numbers when the file mode was set with a preceding 0. The YAML parser used in Salt has been modified to no longer convert these number into octal but to keep them as the correct value so that sls files can be a little cleaner to write.

  State Call Data Files

It was requested that the minion keep a local cache of the most recent executed state run. This has been added and now with state runs the data is stored in a msgpack file in the minion's cachedir.

  Turning Off the Job Cache

A new option has been added to the master configuration file. In previous releases the Salt client would look over the Salt job cache to read in the minion return data. With the addition of the event system the Salt client can now watch for events directly from the master worker processes.

This means that the job cache is no longer a hard requirement. Keep in mind though, that turning off the job cache means that historic job execution data cannot be retrieved.

  Test Updates

  Minion Swarms Are Faster

To continue our efforts with testing Salt's ability to scale the minionswarm script has been updated. The minionswarm can now start up minions much faster than it could before and comes with a new feature allowing modules to be disabled, thus lowering the minion's footprint when making a swarm. These new updates have allows us to test

# python minionswarm.py -m 20 --master salt-master

  Many Fixes

To get a good idea for the number of bugfixes this release offers take a look at the closed tickets for 0.10.0, this is a very substantial update:

https://github.com/saltstack/salt/issues?milestone=12&state=closed

  Master and Minion Stability Fixes

As Salt deployments grow new ways to break Salt are discovered. 0.10.0 comes with a number of fixes for the minions and master greatly improving Salt stability.

  Salt 0.10.2 Release Notes

0.10.2 is out! This release comes with enhancements to the pillar interface, cleaner ways to access the salt-call capabilities in the API, minion data caching and the event system has been added to salt minions.

There have also been updates to the ZeroMQ functions, many more tests (thanks to sponsors, the code sprint and many contributors) and a swath of bug fixes.

  Major Features

  Ext Pillar Modules

The ranks of available Salt modules directories sees a new member in 0.10.2. With the popularity of pillar a higher demand has arisen for ext_pillar interfaces to be more like regular Salt module additions. Now ext_pillar interfaces can be added in the same way as other modules, just drop it into the pillar directory in the salt source.

  Minion Events

In 0.10.0 an event system was added to the Salt master. 0.10.2 adds the event system to the minions as well. Now event can be published on a local minion as well.

The minions can also send events back up to the master. This means that Salt is able to communicate individual events from the minions back up to the Master which are not associated with command.

  Minion Data Caching

When pillar was introduced the landscape for available data was greatly enhanced. The minion's began sending grain data back to the master on a regular basis.

The new config option on the master called minion_data_cache instructs the Salt master to maintain a cache of the minion's grains and pillar data in the cachedir. This option is turned off by default to avoid hitting the disk more, but when enabled the cache is used to make grain matching from the salt command more powerful, since the minions that will match can be pre determined.

  Backup Files

By default all files replaced by the file.managed and file.recurse states we simply deleted. 0.10.2 adds a new option. By setting the backup option to minion the files are backed up before they are replaced.

The backed up files are located in the cachedir under the file_backup directory. On a default system this will be at: /var/cache/salt/file_backup

  Configuration files

salt-master and salt-minion automatically load additional configuration files from master.d/*.conf respective minion.d/*.conf where master.d/minion.d is a directory in the same directory as the main configuration file.

  Salt Key Verification

A number of users complained that they had inadvertently deleted the wrong salt authentication keys. 0.10.2 now displays what keys are going to be deleted and verifies that they are the keys that are intended for deletion.

  Key auto-signing

If autosign_file is specified in the configuration file incoming keys will be compared to the list of keynames in autosign_file. Regular expressions as well as globbing is supported.

The file must only be writable by the user otherwise the file will be ignored. To relax the permission and allow group write access set the permissive_pki_access option.

  Module changes

  Improved OpenBSD support

New modules for managing services and packages were provided by Joshua Elsasser to further improve the support for OpenBSD.

Existing modules like the disk module were also improved to support OpenBSD.

  SQL Modules

The MySQL and PostgreSQL modules have both received a number of additions thanks to the work of Avi Marcus and Roman Imankulov.

  ZFS Support on FreeBSD

A new ZFS module has been added by Kurtis Velarde for FreeBSD supporting various ZFS operations like creating, extending or removing zpools.

  Augeas

A new Augeas module by Ulrich Dangel for editing and verifying config files.

  Native Debian Service module

The support for the Debian was further improved with an new service module for Debian by Ahmad Khayyat supporting disable and enable.

  Cassandra

Cassandra support has been added by Adam Garside. Currently only status and diagnostic information are supported.

  Networking

The networking support for RHEL has been improved and supports bonding support as well as zeroconf configuration.

  Monit

Basic monit support by Kurtis Velarde to control services via monit.

  nzbget

Basic support for controlling nzbget by Joseph Hall

  Bluetooth

Baisc bluez support for managing and controlling Bluetooth devices. Supports scanning as well as pairing/unpairing by Joseph Hall.

  Test Updates

  Consistency Testing

Another testing script has been added. A bug was found in pillar when many minions generated pillar data at the same time. The new consist.py script is the tests directory was created to reproduce bugs where data should always be consistent.

  Many Fixes

To get a good idea for the number of bugfixes this release offers take a look at the closed tickets for 0.10.2, this is a very substantial update:

https://github.com/saltstack/salt/issues?milestone=24&page=1&state=closed

  Master and Minion Stability Fixes

As Salt deployments grow new ways to break Salt are discovered. 0.10.2 comes with a number of fixes for the minions and master greatly improving Salt stability.

  Salt 0.10.3 Release Notes

The latest taste of Salt has come, this release has many fixes and feature additions. Modifications have been made to make ZeroMQ connections more reliable, the beginning of the ACL system is in place, a new command line parsing system has been added, dynamic module distribution has become more environment aware, the new master_finger option and many more!

  Major Features

  ACL System

The new ACL system has been introduced. The ACL system allows for system users other than root to execute salt commands. Users can be allowed to execute specific commands in the same way that minions are opened up to the peer system.

The configuration value to open up the ACL system is called client_acl and is configured like so:

client_acl:
  fred:
    - test..*
    - pkg.list_pkgs

Where fred is allowed access to functions in the test module and to the pkg.list_pkgs function.

  Master Finger Option

The master_finger option has been added to improve the security of minion provisioning. The master_finger option allows for the fingerprint of the master public key to be set in the configuration file to double verify that the master is valid. This option was added in response to a motivation to pre authenticate the master when provisioning new minions to help prevent man in the middle attacks in some situations.

  Salt Key Fingerprint Generation

The ability to generate fingerprints of keys used by Salt has been added to salt-key. The new option finger accepts the name of the key to generate and display a fingerprint for.

salt-key -F master

Will display the fingerprints for the master public and private keys.

  Parsing System

Pedro Algavio, aka s0undt3ch, has added a substantial update to the command line parsing system that makes the help message output much cleaner and easier to search through. Salt parsers now have --versions-report besides usual --version info which you can provide when reporting any issues found.

  Key Generation

We have reduced the requirements needed for salt-key to generate minion keys. You're no longer required to have salt configured and it's common directories created just to generate keys. This might prove useful if you're batch creating keys to pre-load on minions.

  Startup States

A few configuration options have been added which allow for states to be run when the minion daemon starts. This can be a great advantage when deploying with Salt because the minion can apply states right when it first runs. To use startup states set the startup_states configuration option on the minion to highstate.

  New Exclude Declaration

Some users have asked about adding the ability to ensure that other sls files or ids are excluded from a state run. The exclude statement will delete all of the data loaded from the specified sls file or will delete the specified id:

exclude:
  - sls: http
  - id: /etc/vimrc

  Max Open Files

While we're currently unable to properly handle ZeroMQ's abort signals when the max open files is reached, due to the way that's handled on ZeroMQ's, we have minimized the chances of this happening without at least warning the user.

  More State Output Options

Some major changes have been made to the state output system. In the past state return data was printed in a very verbose fashion and only states that failed or made changes were printed by default. Now two options can be passed to the master and minion configuration files to change the behavior of the state output. State output can be set to verbose (default) or non-verbose with the state_verbose option:

state_verbose: False

It is noteworthy that the state_verbose option used to be set to False by default but has been changed to True by default in 0.10.3 due to many requests for the change.

Te next option to be aware of new and called state_output. This option allows for the state output to be set to full (default) or terse.

The full output is the standard state output, but the new terse output will print only one line per state making the output much easier to follow when executing a large state system.

state_output: terse

  state.file.append Improvements

The salt state file.append() tries not to append existing text. Previously the matching check was being made line by line. While this kind of check might be enough for most cases, if the text being appended was multi-line, the check would not work properly. This issue is now properly handled, the match is done as a whole ignoring any white space addition or removal except inside commas. For those thinking that, in order to properly match over multiple lines, salt will load the whole file into memory, that's not true. For most cases this is not important but an erroneous order to read a 4GB file, if not properly handled, like salt does, could make salt chew that amount of memory. Salt has a buffered file reader which will keep in memory a maximum of 256KB and iterates over the file in chunks of 32KB to test for the match, more than enough, if not, explain your usage on a ticket. With this change, also salt.modules.file.contains(), salt.modules.file.contains_regex(), salt.modules.file.contains_glob() and salt.utils.find now do the searching and/or matching using the buffered chunks approach explained above.

Two new keyword arguments were also added, makedirs and source. The first, makedirs will create the necessary directories in order to append to the specified file, of course, it only applies if we're trying to append to a non-existing file on a non-existing directory:

/tmp/salttest/file-append-makedirs:
    file.append:
        text: foo
        makedirs: True

The second, source, allows one to append the contents of a file instead of specifying the text.

/tmp/salttest/file-append-source:
file.append:
    - source: salt://testfile

  Security Fix

A timing vulnerability was uncovered in the code which decrypts the AES messages sent over the network. This has been fixed and upgrading is strongly recommended.

  Salt 0.10.4 Release Notes

Salt 0.10.4 is a monumental release for the Salt team, with two new module systems, many additions to allow granular access to Salt, improved platform support and much more.

This release is also exciting because we have been able to shorten the release cycle back to under a month. We are working hard to keep up the aggressive pace and look forward to having releases happen more frequently!

This release also includes a serious security fix and all users are very strongly recommended to upgrade. As usual, upgrade the master first, and then the minion to ensure that the process is smooth.

  Major Features

  External Authentication System

The new external authentication system allows for Salt to pass through authentication to any authentication system to determine if a user has permission to execute a Salt command. The Unix PAM system is the first supported system with more to come!

The external authentication system allows for specific users to be granted access to execute specific functions on specific minions. Access is configured in the master configuration file, and uses the new access control system:

external_auth:
  pam:
    thatch:
      - 'web*':
        - test.*
        - network.*

The configuration above allows the user thatch to execute functions in the test and network modules on minions that match the web* target.

  Access Control System

All Salt systems can now be configured to grant access to non-administrative users in a granular way. The old configuration continues to work. Specific functions can be opened up to specific minions from specific users in the case of external auth and client ACLs, and for specific minions in the case of the peer system.

Access controls are configured like this:

client_acl:
  fred:
    - web\*:
      - pkg.list_pkgs
      - test.*
      - apache.*

  Target by Network

A new matcher has been added to the system which allows for minions to be targeted by network. This new matcher can be called with the -S flag on the command line and is available in all places that the matcher system is available. Using it is simple:

$ salt -S '192.168.1.0/24' test.ping
$ salt -S '192.168.1.100' test.ping

  Nodegroup Nesting

Previously a nodegroup was limited by not being able to include another nodegroup, this restraint has been lifted and now nodegroups will be expanded within other nodegroups with the N@ classifier.

  Salt Key Delete by Glob

The ability to delete minion keys by glob has been added to salt-key. To delete all minion keys whose minion name starts with 'web':

$ salt-key -d 'web*'

  Master Tops System

The external_nodes system has been upgraded to allow for modular subsystems to be used to generate the top file data for a highstate run.

The external_nodes option still works but will be deprecated in the future in favor of the new master_tops option.

Example of using master_tops:

master_tops:
  ext_nodes: cobbler-external-nodes

  Next Level Solaris Support

A lot of work has been put into improved Solaris support by Romeo Theriault. Packaging modules (pkgadd/pkgrm and pkgutil) and states, cron support and user and group management have all been added and improved upon. These additions along with SMF (Service Management Facility) service support and improved Solaris grain detection in 0.10.3 add up to Salt becoming a great tool to manage Solaris servers with.

  Security

A vulnerability in the security handshake was found and has been repaired, old minions should be able to connect to a new master, so as usual, the master should be updated first and then the minions.

  Pillar Updates

The pillar communication has been updated to add some extra levels of verification so that the intended minion is the only one allowed to gather the data. Once all minions and the master are updated to salt 0.10.4 please activate pillar 2 by changing the pillar_version in the master config to 2. This will be set to 2 by default in a future release.

  Salt 0.10.5 Release Notes

Salt 0.10.5 is ready, and comes with some great new features. A few more interfaces have been modularized, like the outputter system. The job cache system has been made more powerful and can now store and retrieve jobs archived in external databases. The returner system has been extended to allow minions to easily retrieve data from a returner interface.

As usual, this is an exciting release, with many noteworthy additions!

  Major Features

  External Job Cache

The external job cache is a system which allows for a returner interface to also act as a job cache. This system is intended to allow users to store job information in a central location for longer periods of time and to make the act of looking up information from jobs executed on other minions easier.

Currently the external job cache is supported via the mongo and redis returners:

ext_job_cache: redis
redis.host: salt

Once the external job cache is turned on the new ret module can be used on the minions to retrieve return information from the job cache. This can be a great way for minions to respond and react to other minions.

  OpenStack Additions

OpenStack integration with Salt has been moving forward at a blistering pace. The new nova, glance and keystone modules represent the beginning of ongoing OpenStack integration.

The Salt team has had many conversations with core OpenStack developers and is working on linking to OpenStack in powerful new ways.

  Wheel System

A new API was added to the Salt Master which allows the master to be managed via an external API. This new system allows Salt API to easily hook into the Salt Master and manage configs, modify the state tree, manage the pillar and more. The main motivation for the wheel system is to enable features needed in the upcoming web UI so users can manage the master just as easily as they manage minions.

The wheel system has also been hooked into the external auth system. This allows specific users to have granular access to manage components of the Salt Master.

  Render Pipes

Jack Kuan has added a substantial new feature. The render pipes system allows Salt to treat the render system like unix pipes. This new system enables sls files to be passed through specific render engines. While the default renderer is still recommended, different engines can now be more easily merged. So to pipe the output of Mako used in YAML use this shebang line:

#!mako|yaml

  Salt Key Overhaul

The Salt Key system was originally developed as only a CLI interface, but as time went on it was pressed into becoming a clumsy API. This release marks a complete overhaul of Salt Key. Salt Key has been rewritten to function purely from an API and to use the outputter system. The benefit here is that the outputter system works much more cleanly with Salt Key now, and the internals of Salt Key can be used much more cleanly.

  Modular Outputters

The outputter system is now loaded in a modular way. This means that output systems can be more easily added by dropping a python file down on the master that contains the function output.

  Gzip from Fileserver

Gzip compression has been added as an option to the cp.get_file and cp.get_dir commands. This will make file transfers more efficient and faster, especially over slower network links.

  Unified Module Configuration

In past releases of Salt, the minions needed to be configured for certain modules to function. This was difficult because it required pre-configuring the minions. 0.10.5 changes this by making all module configs on minions search the master config file for values.

Now if a single database server is needed, then it can be defined in the master config and all minions will become aware of the configuration value.

  Salt Call Enhancements

The salt-call command has been updated in a few ways. Now, salt-call can take the --return option to send the data to a returner. Also, salt-call now reports executions in the minion proc system, this allows the master to be aware of the operation salt-call is running.

  Death to pub_refresh and sub_timeout

The old configuration values pub_refresh and sub_timeout have been removed. These options were in place to alleviate problems found in earlier versions of ZeroMQ which have since been fixed. The continued use of these options has proven to cause problems with message passing and have been completely removed.

  Git Revision Versions

When running Salt directly from git (for testing or development, of course) it has been difficult to know exactly what code is being executed. The new versioning system will detect the git revision when building and how many commits have been made since the last release. A release from git will look like this:

0.10.4-736-gec74d69

  Svn Module Addition

Anthony Cornehl (twinshadow) contributed a module that adds Subversion support to Salt. This great addition helps round out Salt's VCS support.

  Noteworthy Changes

  Arch Linux Defaults to Systemd

Arch Linux recently changed to use systemd by default and discontinued support for init scripts. Salt has followed suit and defaults to systemd now for managing services in Arch.

  Salt, Salt Cloud and Openstack

With the releases of Salt 0.10.5 and Salt Cloud 0.8.2, OpenStack becomes the first (non-OS) piece of software to include support both on the user level (with Salt Cloud) and the admin level (with Salt). We are excited to continue to extend support of other platforms at this level.

  Salt 0.11.0 Release Notes

Salt 0.11.0 is here, with some highly sought after and exciting features. These features include the new overstate system, the reactor system, a new state run scope component called __context__, the beginning of the search system (still needs a great deal of work), multiple package states, the MySQL returner and a better system to arbitrarily reference outputters.

It is also noteworthy that we are changing how we mark release numbers. For the life of the project we have been pushing every release with features and fixes as point releases. We will now be releasing point releases for only bug fixes on a more regular basis and major feature releases on a slightly less regular basis. This means that the next release will be a bugfix only release with a version number of 0.11.1. The next feature release will be named 0.12.0 and will mark the end of life for the 0.11 series.

  Major Features

  OverState

The overstate system is a simple way to manage rolling state executions across many minions. The overstate allows for a state to depend on the successful completion of another state.

  Reactor System

The new reactor system allows for a reactive logic engine to be created which can respond to events within a salted environment. The reactor system uses sls files to match events fired on the master with actions, enabling Salt to react to problems in an infrastructure.

Your load-balanced group of webservers is under extra load? Spin up a new VM and add it to the group. Your fileserver is filling up? Send a notification to your sysadmin on call. The possibilities are endless!

  Module Context

A new component has been added to the module loader system. The module context is a data structure that can hold objects for a given scope within the module.

This allows for components that are initialized to be stored in a persistent context which can greatly speed up ongoing connections. Right now the best example can be found in the cp execution module.

  Multiple Package Management

A long desired feature has been added to package management. By definition Salt States have always installed packages one at a time. On most platforms this is not the fastest way to install packages. Erik Johnson, aka archtaku, has modified the package modules for many providers and added new capabilities to install groups of packages. These package groups can be defined as a list of packages available in repository servers:

python_pkgs:
  pkg.installed:
    - pkgs:
      - python-mako
      - whoosh
      - python-git

or specify based on the location of specific packages:

python_pkgs:
  pkg.installed:
    - sources:
      - python-mako: http://some-rpms.org/python-mako.rpm
      - whoosh: salt://whoosh/whoosh.rpm
      - python-git: ftp://companyserver.net/python-git.rpm

  Search System

The bones to the search system have been added. This is a very basic interface that allows for search backends to be added as search modules. The first supported search module is the whoosh search backend. Right now only the basic paths for the search system are in place, making this very experimental. Further development will involve improving the search routines and index routines for whoosh and other search backends.

The search system has been made to allow for searching through all of the state and pillar files, configuration files and all return data from minion executions.

  Notable Changes

All previous versions of Salt have shared many directories between the master and minion. The default locations for keys, cached data and sockets has been shared by master and minion. This has created serious problems with running a master and a minion on the same systems. 0.11.0 changes the defaults to be separate directories. Salt will also attempt to migrate all of the old key data into the correct new directories, but if it is not successful it may need to be done manually. If your keys exhibit issues after updating make sure that they have been moved from /etc/salt/pki to /etc/salt/pki/{master,minion}.

The old setup will look like this:

/etc/salt/pki
|-- master.pem
|-- master.pub
|-- minions
|   `-- ragnarok.saltstack.net
|-- minions_pre
|-- minion.pem
|-- minion.pub
|-- minion_master.pub
|-- minions_pre
`-- minions_rejected

With the accepted minion keys in /etc/salt/pki/minions, the new setup places the accepted minion keys in /etc/salt/pki/master/minions

/etc/salt/pki
|-- master
|   |-- master.pem
|   |-- master.pub
|   |-- minions
|   |   `-- ragnarok.saltstack.net
|   |-- minions_pre
|   `-- minions_rejected
|-- minion
|   |-- minion.pem
|   |-- minion.pub
|   `-- minion_master.pub

  Salt 0.12.0 Release Notes

Another feature release of Salt is here! Some exciting additions are included with more ways to make salt modular and even easier management of the salt file server.

  Major Features

  Modular Fileserver Backend

The new modular fileserver backend allows for any external system to be used as a salt file server. The main benefit here is that it is now possible to tell the master to directly use a git remote location, or many git remote locations, automatically mapping git branches and tags to salt environments.

  Windows is First Class!

A new Salt Windows installer is now available! Much work has been put in to improve Windows support. With this much easier method of getting Salt on your Windows machines, we hope even more development and progress will occur. Please file bug reports on the Salt github repo issue tracker so we can continue improving.

One thing that is missing on Windows that Salt uses extensively is a software package manager and a software package repository. The Salt pkg state allows sys admins to install software across their infrastructure and across operating systems. Software on Windows can now be managed in the same way. The SaltStack team built a package manager that interfaces with the standard Salt pkg module to allow for installing and removing software on Windows. In addition, a software package repository has been built on top of the Salt fileserver. A small YAML file provides the information necessary for the package manager to install and remove software.

An interesting feature of the new Salt Windows software package repository is that one or more remote git repositories can supplement the master's local repository. The repository can point to software on the master's fileserver or on an HTTP, HTTPS, or ftp server.

  New Default Outputter

Salt displays data to the terminal via the outputter system. For a long time the default outputter for Salt has been the python pretty print library. While this has been a generally reasonable outputter, it did have many failings. The new default outputter is called "nested", it recursively scans return data structures and prints them out cleanly.

If the result of the new nested outputter is not desired any other outputter can be used via the --out option, or the output option can be set in the master and minion configs to change the default outputter.

  Internal Scheduler

The internal Salt scheduler is a new capability which allows for functions to be executed at given intervals on the minion, and for runners to be executed at given intervals on the master. The scheduler allows for sequences such as executing state runs (locally on the minion or remotely via an overstate) or continually gathering system data to be run at given intervals.

The configuration is simple, add the schedule option to the master or minion config and specify jobs to run, this in the master config will execute the state.over runner every 60 minutes:

schedule:
  overstate:
    function: state.over
    minutes: 60

This example for the minion configuration will execute a highstate every 30 minutes:

schedule:
  highstate:
    function: state.highstate
    minutes: 30

  Optional DSL for SLS Formulas

Jack Kuan, our renderer expert, has created something that is astonishing. Salt, now comes with an optional Python based DSL, this is a very powerful interface that makes writing SLS files in pure python easier than it was with the raw py renderer. As usual this can be used with the renderer shebang line, so a single sls can be written with the DSL if pure python power is needed while keeping other sls files simple with YAML.

  Set Grains Remotely

A new execution function and state module have been added that allows for grains to be set on the minion. Now grains can be set via a remote execution or via states. Use the grains.present state or the grains.setval execution functions.

  Gentoo Additions

Major additions to Gentoo specific components have been made. The encompasses executions modules and states ranging from supporting the make.conf file to tools like layman.

  Salt 0.13.0 Release Notes

The lucky number 13 has turned the corner! From CLI notifications when quitting a salt command, to substantial improvements on Windows, Salt 0.13.0 has arrived!

  Major Features

  Improved file.recurse Performance

The file.recurse system has been deployed and used in a vast array of situations. Fixes to the file state and module have led towards opening up new ways of running file.recurse to make it faster. Now the file.recurse state will download fewer files and will run substantially faster.

  Windows Improvements

Minion stability on Windows has improved. Many file operations, including file.recurse, have been fixed and improved. The network module works better, to include network.interfaces. Both 32bit and 64bit installers are now available.

  Nodegroup Targeting in Peer System

In the past, nodegroups were not available for targeting via the peer system. This has been fixed, allowing the new nodegroup expr_form argument for the publish.publish function: salt-call publish.publish group1 test.ping expr_form=nodegroup

  Blacklist Additions

Additions allowing more granular blacklisting are available in 0.13.0. The ability to blacklist users and functions in client_acl have been added, as well as the ability to exclude state formulas from the command line.

  Command Line Pillar Embedding

Pillar data can now be embedded on the command line when calling state.sls and state.highstate. This allows for on the fly changes or settings to pillar and makes parameterizing state formulas even easier. This is done via the keyword argument: salt * state.highstate pillar='{"cheese": "spam"}'

The above example will extend the existing pillar to hold the cheese key with a value of spam. If the cheese key is already specified in the minion's pillar then it will be overwritten.

  CLI Notifications

In the past hitting ctrl-C and quitting from the salt command would just drop to a shell prompt, this caused confusion with users who expected the remote executions to also quit. Now a message is displayed showing what command can be used to track the execution and what the job id is for the execution.

  Version Specification in Multiple-Package States

Versions can now be specified within multiple-package pkg.installed states. An example can be found below:

mypkgs:
  pkg.installed:
    - pkgs:
      - foo
      - bar: 1.2.3-4
      - baz

  Noteworthy Changes

The configuration subsystem in Salt has been overhauled to make the opts dict used by Salt applications more portable, the problem is that this is an incompatible change with salt-cloud, and salt-cloud will need to be updated to the latest git to work with Salt 0.13.0. Salt Cloud 0.8.5 will also require Salt 0.13.0 or later to function.

The Salt Stack team is sorry for the inconvenience here, we work hard to make sure these sorts of things do not happen, but sometimes hard changes get in.

  Salt 0.14.0 Release Notes

Salt 0.14.0 is here! This release was held up primarily by PyCon, Scale and illness, but has arrived! 0.14.0 comes with many new features and is breaking ground for Salt in the area of cloud management with the introduction of Salt providing basic cloud controller functionallity.

  Major Features

  Salt - As a Cloud Controller

This is the first primitive inroad to using Salt as a cloud controller is available in 0.14.0. Be advised that this is alpha, only tested in a few very small environments.

The cloud controler is built using kvm and libvirt for the hypervisors. Hypervisors are autodetected as minions and only need to have libvirt running and kvm installed to function. The features of the Salt cloud controller are as follows:

•   Basic vm discovery and reporting

•   Creation of new virtual machines

•   Seeding virtual machines with Salt via qemu-nbd or libguestfs

•   Live migration (shared and non shared storage)

•   Delete existing VMs

    It is noteworthy that this feature is still Alpha, meaning that all rights are reserved to change the interface if needs be in future releases!

  Libvirt State

One of the problems with libvirt is management of certificates needed for live migration and cross communication between hypervisors. The new libvirt state makes the Salt Master hold a CA and manage the signing and distribution of keys onto hypervisors, just add a call to the libvirt state in the sls formulas used to set up a hypervisor:

libvirt_keys:
  libvirt.keys

  New get Functions

An easier way to manage data has been introduced. The pillar, grains and config execution modules have been extended with the new get function. This funtion works much in the same way as the get method in a python dict, but with an enhancement, nested dict components can be extracted using a : delimiter.

If a structure like this is in pillar:

foo:
  bar:
    baz: quo

Extracting it from the raw pillar in an sls formula or file template is done this way:

{{ pillar['foo']['bar']['baz'] }}

Now with the new get function the data can be safely gathered and a default can be set allowing the template to fall back if the value is not available:

{{ salt['pillar.get']('foo:bar:baz', 'qux') }}

This makes handling nested structures much easier, and defaults can be cleanly set. This new funcion is being used extensively in the new formulae repository of salt sls formulas.

  Salt 0.6.0 release notes

The Salt remote execution manager has reached initial functionality! Salt is a management application which can be used to execute commands on remote sets of servers.

The whole idea behind Salt is to create a system where a group of servers can be remotely controlled from a single master, not only can commands be executed on remote systems, but salt can also be used to gather information about your server environment.

Unlike similar systems, like Func and MCollective, Salt is extremely simple to setup and use, the entire application is contained in a single package, and the master and minion daemons require no running dependencies in the way that Func requires Certmaster and MCollective requires activeMQ.

Salt also manages authentication and encryption. Rather than using SSL for encryption, salt manages encryption on a payload level, so the data sent across the network is encrypted with fast AES encryption, and authentication uses RSA keys. This means that Salt is fast, secure, and very efficient.

Messaging in Salt is executed with ZeroMQ, so the message passing interface is built into salt and does not require an external ZeroMQ server. This also adds speed to Salt since there is no additional bloat on the networking layer, and ZeroMQ has already proven itself as a very fast networking system.

The remote execution in Salt is "Lazy Execution", in that once the command is sent the requesting network connection is closed. This makes it easier to detach the execution from the calling process on the master, it also means that replies are cached, so that information gathered from historic commands can be queried in the future.

Salt also allows users to make execution modules in Python. Writers of these modules should also be pleased to know that they have access to the impressive information gathered from PuppetLabs' Facter application, making Salt module more flexible. In the future I hope to also allow Salt to group servers based on Facter information as well.

All in all Salt is fast, efficient and clean, can be used from a simple command line client or through an API, uses message queue technology to make network execution extremely fast, and encryption is handled in a very fast and efficient manner. Salt is also VERY easy to use and VERY easy to extend.

You can find the source code for Salt on my github page, I have also set up a few wiki pages explaining how to use and set up Salt. If you are using Arch Linux there is a package available in the Arch Linux AUR.

Salt 0.6.0 Source: https://github.com/downloads/saltstack/salt/salt-0.6.0.tar.gz

Github page: https://github.com/saltstack/salt

Wiki: https://github.com/saltstack/salt/wiki

Arch Linux Package: https://aur.archlinux.org/packages.php?ID=47512

I am very open to contributions, for instance I need packages for more Linux distributions as well as BSD packages and testers.

Give Salt a try, this is the initial release and is not a 1.0 quality release, but it has been working well for me! I am eager to get your feedback!

  Salt 0.7.0 release notes

I am pleased to announce the release of Salt 0.7.0!

This release marks what is the first stable release of salt, 0.7.0 should be suitable for general use.

0.7.0 Brings the following new features to Salt:

•   Integration with Facter data from puppet labs

•   Allow for matching minions from the salt client via Facter information

•   Minion job threading, many jobs can be executed from the master at once

•   Preview of master clustering support - Still experimental

•   Introduce new minion modules for stats, virtualization, service management and more

•   Add extensive logging to the master and minion daemons

•   Add sys.reload_functions for dynamic function reloading

•   Greatly improve authentication

•   Introduce the saltkey command for managing public keys

•   Begin backend development preparatory to introducing butter

•   Addition of man pages for the core commands

•   Extended and cleaned configuration

    0.7.0 Fixes the following major bugs:

•   Fix crash in minions when matching failed

•   Fix configuration file lookups for the local client

•   Repair communication bugs in encryption

•   Numerous fixes in the minion modules

    The next release of Salt should see the following features:

•   Stabilize the cluster support

•   Introduce a remote client for salt command tiers

•   salt-ftp system for distributed file copies

•   Initial support for "butter"

    Coming up next is a higher level management framework for salt called Butter. I want salt to stay as a simple and effective communication framework, and allow for more complicated executions to be managed via Butter.

    Right now Butter is being developed to act as a cloud controller using salt as the communication layer, but features like system monitoring and advanced configuration control (a puppet manager) are also in the pipe.

    Special thanks to Joseph Hall for the status and network modules, and thanks to Matthias Teege for tracking down some configuration bugs!

    Salt can be downloaded from the following locations;

    Source Tarball:

    https://github.com/downloads/saltstack/salt/salt-0.7.0.tar.gz

    Arch Linux Package:

    https://aur.archlinux.org/packages.php?ID=47512

    Please enjoy the latest Salt release!

  Salt 0.8.0 release notes

Salt 0.8.0 is ready for general consumption! The source tarball is available on github for download:

https://github.com/downloads/saltstack/salt/salt-0.8.0.tar.gz

A lot of work has gone into salt since the last release just 2 weeks ago, and salt has improved a great deal. A swath of new features are here along with performance and threading improvements!

The main new features of salt 0.8.0 are:

Salt-cp

Cython minion modules

Dynamic returners

Faster return handling

Lowered required Python version to 2.6

Advanced minion threading

Configurable minion modules

  Salt-cp -

The salt-cp command introduces the ability to copy simple files via salt to targeted servers. Using salt-cp is very simple, just call salt-cp with a target specification, the source file(s) and where to copy the files on the minions. For instance:

# salt-cp ‘*’ /etc/hosts /etc/hosts

Will copy the local /etc/hosts file to all of the minions.

Salt-cp is very young, in the future more advanced features will be added, and the functionality will much more closely resemble the cp command.

  Cython minion modules -

Cython is an amazing tool used to compile Python modules down to c. This is arguably the fastest way to run Python code, and since pyzmq requires cython, adding support to salt for cython adds no new dependencies.

Cython minion modules allow minion modules to be written in cython and therefore executed in compiled c. Simply write the salt module in cython and use the file extension “.pyx” and the minion module will be compiled when the minion is started. An example cython module is included in the main distribution called cytest.pyx:

https://github.com/saltstack/salt/blob/develop/salt/modules/cytest.pyx

  Dynamic Returners -

By default salt returns command data back to the salt master, but now salt can return command data to any system. This is enabled via the new returners modules feature for salt. The returners modules take the return data and sends it to a specific module. The returner modules work like minion modules, so any returner can be added to the minions.

This means that a custom data returner can be added to communicate the return data so anything from MySQL, Redis, MongoDB and more!

There are 2 simple stock returners in the returners directory:

https://github.com/saltstack/salt/blob/develop/salt/returners

The documentation on writing returners will be added to the wiki shortly, and returners can be written in pure Python, or in cython.

  Configurable Minion Modules -

Minion modules may need to be configured, now the options passed to the minion configuration file can be accessed inside of the minion modules via the __opt__ dict.

Information on how to use this simple addition has been added to the wiki: https://github.com/thatch45/salt/wiki/Writing-Salt-Modules

The test module has an example of using the __opts__ dict, and how to set default options:

https://github.com/saltstack/salt/blob/develop/salt/modules/test.py

  Advanced Minion Threading:

In 0.7.0 the minion would block after receiving a command from the master, now the minion will spawn a thread or multiprocess. By default Python threads are used because for general use they have proved to be faster, but the minion can now be configured to use the Python multiprocessing module instead. Using multiprocessing will cause executions that are CPU bound or would otherwise exploit the negative aspects of the Python GIL to run faster and more reliably, but simple calls will still be faster with Python threading. The configuration option can be found in the minion configuration file:

https://github.com/saltstack/salt/blob/develop/conf/minion

Lowered Supported Python to 2.6 -

The requirement for Python 2.7 has been removed to support Python 2.6. I have received requests to take the minimum Python version back to 2.4, but unfortunately this will not be possible, since the ZeroMQ Python bindings do not support Python 2.4.

Salt 0.8.0 is a very major update, it also changes the network protocol slightly which makes communication with older salt daemons impossible, your master and minions need to be upgraded together! I could use some help bringing salt to the people! Right now I only have packages for Arch Linux, Fedora 14 and Gentoo. We need packages for Debian and people willing to help test on more platforms. We also need help writing more minion modules and returner modules. If you want to contribute to salt please hop on the mailing list and send in patches, make a fork on github and send in pull requests! If you want to help but are not sure where you can, please email me directly or post tot he mailing list!

I hope you enjoy salt, while it is not yet 1.0 salt is completely viable and usable!

-Thomas S. Hatch

  Salt 0.8.7 release notes

It has been a month since salt 0.8.0, and it has been a long month! But Salt is still coming along strong. 0.8.7 has a lot of changes and a lot of updates. This update makes Salt’s ZeroMQ back end better, strips Facter from the dependencies, and introduces interfaces to handle more capabilities.

Many of the major updates are in the background, but the changes should shine through to the surface. A number of the new features are still a little thin, but the back end to support expansion is in place.

I also recently gave a presentation to the Utah Python users group in Salt Lake City, the slides from this presentation are available here: https://github.com/downloads/saltstack/salt/Salt.pdf

The video from this presentation will be available shortly.

The major new features and changes in Salt 0.8.7 are:

•   Revamp ZeroMQ topology on the master for better scalability

•   State enforcement

•   Dynamic state enforcement managers

•   Extract the module loader into salt.loader

•   Make Job ids more granular

•   Replace Facter functionality with the new salt grains interface

•   Support for “virtual” salt modules

•   Introduce the salt-call command

•   Better debugging for minion modules

    The new ZeroMQ topology allows for better scalability, this will be required by the need to execute massive file transfers to multiple machines in parallel and state management. The new ZeroMQ topology is available in the aforementioned presentation.

    0.8.7 introduces the capability to declare states, this is similar to the capabilities of Puppet. States in salt are declared via state data structures. This system is very young, but the core feature set is available. Salt states work around rendering files which represent Salt high data. More on the Salt state system will be documented in the near future.

    The system for loading salt modules has been pulled out of the minion class to be a standalone module, this has enabled more dynamic loading of Salt modules and enables many of the updates in 0.8.7 –

    https://github.com/saltstack/salt/blob/develop/salt/loader.py

    Salt Job ids are now microsecond precise, this was needed to repair a race condition unveiled by the speed improvements in the new ZeroMQ topology.

    The new grains interface replaces the functionality of Facter, the idea behind grains differs from Facter in that the grains are only used for static system data, dynamic data needs to be derived from a call to a salt module. This makes grains much faster to use, since the grains data is generated when the minion starts.

    Virtual salt modules allows for a salt module to be presented as something other than its module name. The idea here is that based on information from the minion decisions about which module should be presented can be made. The best example is the pacman module. The pacman module will only load on Arch Linux minions, and will be called pkg. Similarly the yum module will be presented as pkg when the minion starts on a Fedora/RedHat system.

    The new salt-call command allows for minion modules to be executed from the minion. This means that on the minion a salt module can be executed, this is a great tool for testing Salt modules. The salt-call command can also be used to view the grains data.

    In previous releases when a minion module threw an exception very little data was returned to the master. Now the stack trace from the failure is returned making debugging of minion modules MUCH easier.

    Salt is nearing the goal of 1.0, where the core feature set and capability is complete!

  Salt 0.8.8 release notes

Salt 0.8.8 is here! This release adds a great deal of code and some serious new features. The latest release can be downloaded here: https://github.com/downloads/saltstack/salt/salt-0.8.8.tar.gz

Improved Documentation has been set up for salt using sphinx thanks to the efforts of Seth House. This new documentation system will act as the back end to the salt website which is still under heavy development. The new sphinx documentation system has also been used to greatly clean up the salt manpages. The salt 7 manpage in particular now contains extensive information which was previously only in the wiki. The new documentation can be found at: http://thatch45.github.com/salt-www/ We still have a lot to add, and when the domain is set up I will post another announcement.

More additions have been made to the ZeroMQ setup, particularly in the realm of file transfers. Salt 0.8.8 introduces a built in, stateless, encrypted file server which allows salt minions to download files from the salt master using the same encryption system used for all other salt communications. The main motivation for the salt file server has been to facilitate the new salt state system.

Much of the salt code has been cleaned up and a new cleaner logging system has been introduced thanks to the efforts of Pedro Algarvio. These additions will allow for much more flexible logging to be executed by salt, and fixed a great deal of my poor spelling in the salt docstrings! Pedro Algarvio has also cleaned up the API, making it easier to embed salt into another application.

The biggest addition to salt found in 0.8.8 is the new state system. The salt module system has received a new front end which allows salt to be used as a configuration management system. The configuration management system allows for system configuration to be defined in data structures. The configuration management system, or as it is called in salt, the “salt state system” supports many of the features found in other configuration managers, but allows for system states to be written in a far simpler format, executes at blazing speeds, and operates via the salt minion matching system. The state system also operates within the normal scope of salt, and requires no additional configuration to use.

The salt state system can enforce the following states with many more to come: Packages Files Services Executing commands Hosts

The system used to define the salt states is based on a data structure, the data structure used to define the salt states has been made to be as easy to use as possible. The data structure is defined by default using a YAML file rendered via a Jinja template. This means that the state definition language supports all of the data structures that YAML supports, and all of the programming constructs and logic that Jinja supports. If the user does not like YAML or Jinja the states can be defined in yaml-mako, json-jinja, or json-mako. The system used to render the states is completely dynamic, and any rendering system can be added to the capabilities of Salt, this means that a rendering system that renders XML data in a cheetah template, or whatever you can imagine, can be easily added to the capabilities of salt.

The salt state system also supports isolated environments, as well as matching code from several environments to a single salt minion.

The feature base for Salt has grown quite a bit since my last serious documentation push. As we approach 0.9.0 the goals are becoming very clear, and the documentation needs a lot of work. The main goals for 0.9.0 are to further refine the state system, fix any bugs we find, get Salt running on as many platforms as we can, and get the documentation filled out. There is a lot more to come as Salt moves forward to encapsulate a much larger scope, while maintaining supreme usability and simplicity.

  Salt 0.8.9 Release Notes

Salt 0.8.9 has finally arrived! Unfortunately this is much later than I had hoped to release 0.8.9, life has been very crazy over the last month. But despite challenges, Salt has moved forward!

This release, as expected, adds few new features and many refinements. One of the most exciting aspect of this release is that the development community for salt has grown a great deal and much of the code is from contributors.

Also, I have filled out the documentation a great deal. So information on States is properly documented, and much of the documentation that was out of date has been filled in.

  Download!

The Salt source can be downloaded from the salt github site:

https://github.com/downloads/saltstack/salt/salt-0.8.9.tar.gz

Or from PyPI:

http://pypi.python.org/packages/source/s/salt/salt-0.8.9.tar.gz

Here s the md5sum:

7d5aca4633bc22f59045f59e82f43b56

For instructions on how to set up Salt please see the installation instructions.

  New Features

  Salt Run

A big feature is the addition of Salt run, the salt-run command allows for master side execution modules to be made that gather specific information or execute custom routines from the master.

Documentation for salt-run can be found here:

http://saltstack.org/ref/runners.html

  Refined Outputters

One problem often complained about in salt was the fact that the output was so messy. Thanks to help from Jeff Schroeder a cleaner interface for the command output for the Salt CLI has been made. This new interface makes adding new printout formats easy and additions to the capabilities of minion modules makes it possible to set the printout mode or outputter for functions in minion modules.

  Cross Calling Salt Modules

Salt modules can now call each other, the __salt__ dict has been added to the predefined references in minion modules. This new feature is documented in the modules documentation:

http://saltstack.org/ref/modules/index.html

  Watch Option Added to Salt State System

Now in Salt states you can set the watch option, this will allow watch enabled states to change based on a change in the other defined states. This is similar to subscribe and notify statements in puppet.

  Root Dir Option

Travis Cline has added the ability to define the option root_dir which allows the salt minion to operate in a subdir. This is a strong move in supporting the minion running as an unprivileged user

  Config Files Defined in Variables

Thanks again to Travis Cline, the master and minion configuration file locations can be defined in environment variables now.

  New Modules

Quite a few new modules, states, returners and runners have been made.

  New Minion Modules

  apt

Support for apt-get has been added, this adds greatly improved Debian and Ubuntu support to Salt!

  useradd and groupadd

Support for manipulating users and groups on Unix-like systems.

  moosefs

Initial support for reporting on aspects of the distributed file system, MooseFS. For more information on MooseFS please see: http://moosefs.org

Thanks to Joseph Hall for his work on MooseFS support.

  mount

Manage mounts and the fstab.

  puppet

Execute puppet on remote systems.

  shadow

Manipulate and manage the user password file.

  ssh

Interact with ssh keys.

  New States

  user and group

Support for managing users and groups in Salt States.

  mount

Enforce mounts and the fstab.

  New Returners

  mongo_return

Send the return information to a MongoDB server.

  New Runners

  manage

Display minions that are up or down.

  Salt 0.9.0 Release Notes

Salt 0.9.0 is here. This is an exciting release, 0.9.0 includes the new network topology features allowing peer salt commands and masters of masters via the syndic interface.

0.9.0 also introduces many more modules, improvements to the API and improvements to the ZeroMQ systems.

  Download!

The Salt source can be downloaded from the salt github site:

https://github.com/downloads/saltstack/salt/salt-0.9.0.tar.gz

Here is the md5sum:

9a925da04981e65a0f237f2e77ddab37

For instructions on how to set up Salt please see the installation instructions.

  New Features

  Salt Syndic

The new Syndic interface allows a master to be commanded via another higher level salt master. This is a powerful solution allowing a master control structure to exist, allowing salt to scale to much larger levels then before.

http://saltstack.org/ref/syndic.html

  Peer Communication

0.9.0 introduces the capability for a minion to call a publication on the master and receive the return from another set of minions. This allows salt to act as a communication channel between minions and as a general infrastructure message bus.

Peer communication is turned off by default but can be enabled via the peer option in the master configuration file. Documentation on the new peer interface can be found here:

http://saltstack.org/ref/peer.html

  Easily Extensible API

The minion and master classes have been redesigned to allow for specialized minion and master servers to be easily created. An example on how this is done for the master can be found in the master.py salt module:

https://github.com/saltstack/salt/blob/develop/salt/master.py

The Master class extends the SMaster class and set up the main master server.

The minion functions can now also be easily added to another application via the SMinion class, this class can be found in the minion.py module:

https://github.com/saltstack/salt/blob/develop/salt/minion.py

  Cleaner Key Management

This release changes some of the key naming to allow for multiple master keys to be held based on the type of minion gathering the master key.

The -d option has also been added to the salt-key command allowing for easy removal of accepted public keys.

The --gen-keys option is now available as well for salt-key, this allows for a salt specific RSA key pair to be easily generated from the command line.

  Improved 0MQ Master Workers

The 0MQ worker system has been further refined to be faster and more robust. This new system has been able to handle a much larger load than the previous setup. The new system uses the IPC protocol in 0MQ instead of TCP.

  New Modules

Quite a few new modules have been made.

  New Minion Modules

  apache

Work directly with apache servers, great for managing balanced web servers

  cron

Read out the contents of a systems crontabs

  mdadm

Module to manage raid devices in Linux, appears as the raid module

  mysql

Gather simple data from MySQL databases

  ps

Extensive utilities for managing processes

  publish

Used by the peer interface to allow minions to make publications

  Salt 0.9.2 Release Notes

Salt 0.9.2 has arrived! 0.9.2 is primarily a bugfix release, the exciting component in 0.9.2 is greatly improved support for salt states. All of the salt states interfaces have been more thoroughly tested and the new salt-states git repo is growing with example of how to use states.

This release introduces salt states for early developers and testers to start helping us clean up the states interface and make it ready for the world!

0.9.2 also fixes a number of bugs found on Python 2.6.

  Download!

The Salt source can be downloaded from the salt github site:

https://github.com/downloads/saltstack/salt/salt-0.9.2.tar.gz

Or from PyPI:

http://pypi.python.org/packages/source/s/salt/salt-0.9.2.tar.gz

For instructions on how to set up Salt please see the installation instructions.

  New Features

  Salt-Call Additions

The salt-call command has received an overhaul, it now hooks into the outputter system so command output looks clean, and the logging system has been hooked into salt-call, so the -l option allows the logging output from salt minion functions to be displayed.

The end result is that the salt-call command can execute the state system and return clean output:

# salt-call state.highstate

  State System Fixes

The state system has been tested and better refined. As of this release the state system is ready for early testers to start playing with. If you are interested in working with the state system please check out the (still very small) salt-states github repo:

https://github.com/thatch45/salt-states

This git repo is the active development branch for determining how a clean salt-state database should look and act. Since the salt state system is still very young a lot of help is still needed here. Please fork the salt-states repo and help us develop a truly large and scalable system for configuration management!

  Notable Bug Fixes

  Python 2.6 String Formatting

Python 2.6 does not support format strings without an index identifier, all of them have been repaired.

  Cython Loading Disabled by Default

Cython loading requires a development tool chain to be installed on the minion, requiring this by default can cause problems for most Salt deployments. If Cython auto loading is desired it will need to be turned on in the minion config.

  Salt 0.9.3 Release Notes

Salt 0.9.3 is finally arrived. This is another big step forward for Salt, new features range from proper FreeBSD support to fixing issues seen when attaching a minion to a master over the Internet.

The biggest improvements in 0.9.3 though can be found in the state system, it has progressed from something ready for early testers to a system ready to compete with platforms such as Puppet and Chef. The backbone of the state system has been greatly refined and many new features are available.

  Download!

The Salt source can be downloaded from the salt github site:

https://github.com/downloads/saltstack/salt/salt-0.9.3.tar.gz

Or from PyPI:

http://pypi.python.org/packages/source/s/salt/salt-0.9.3.tar.gz

For instructions on how to set up Salt please see the installation instructions.

  New Features

  WAN Support

Recently more people have been testing Salt minions connecting to Salt Masters over the Internet. It was found that Minions would commonly loose their connection to the master when working over the internet. The minions can now detect if the connection has been lost and reconnect to the master, making WAN connections much more reliable.

  State System Fixes

Substantial testing has gone into the state system and it is ready for real world usage. A great deal has been added to the documentation for states and the modules and functions available to states have been cleanly documented.

A number of State System bugs have also been founds and repaired, the output from the state system has also been refined to be extremely clear and concise.

Error reporting has also been introduced, issues found in sls files will now be clearly reported when executing Salt States.

  Extend Declaration

The Salt States have also gained the extend declaration. This declaration allows for states to be cleanly modified in a post environment. Simply said, if there is an apache.sls file that declares the apache service, then another sls can include apache and then extend it:

include:
  - apache
extend:
  apache:
    service:
      - require:
        - pkg: mod_python
mod_python:
  pkg:
    - installed

The notable behavior with the extend functionality is that it literally extends or overwrites a declaration set up in another sls module. This means that Salt will behave as though the modifications were made directly to the apache sls. This ensures that the apache service in this example is directly tied to all requirements.

  Highstate Structure Specification

This release comes with a clear specification of the Highstate data structure that is used to declare Salt States. This specification explains everything that can be declared in the Salt SLS modules.

The specification is extremely simple, and illustrates how Salt has been able to fulfill the requirements of a central configuration manager within a simple and easy to understand format and specification.

  SheBang Renderer Switch

It came to our attention that having many renderers means that there may be a situation where more than one State Renderer should be available within a single State Tree.

The method chosen to accomplish this was something already familiar to developers and systems administrators, a SheBang. The Python State Renderer displays this new capability.

  Python State Renderer

Until now Salt States could only be declared in yaml or json using Jinja or Mako. A new, very powerful, renderer has been added, making it possible to write Salt States in pure Python:

#!py
def run():
    '''
    Install the python-mako package
    '''
    return {'include': ['python'],
            'python-mako': {'pkg': ['installed']}}

This renderer is used by making a run function that returns the Highstate data structure. Any capabilities of Python can be used in pure Python sls modules.

This example of a pure Python sls module is the same as this example in yaml:

include:
  - python
python-mako:
  pkg:
    - installed

  FreeBSD Support

Additional support has been added for FreeBSD, this is Salt's first branch out of the Linux world and proves the viability of Salt on non-Linux platforms.

Salt remote execution already worked on FreeBSD, and should work without issue on any Unix-like platform. But this support comes in the form of package management and user support, so Salt States also work on FreeBSD now.

The new freebsdpkg module provides package management support for FreeBSD and the new pw_user and pw_group provide user and group management.

  Module and State Additions

  Cron Support

Support for managing the system crontab has been added, declaring a cron state can be done easily:

date > /tmp/datestamp:
  cron:
    - present
    - user: fred
    - minute: 5
    - hour: 3

  File State Additions

The file state has been given a number of new features, primarily the directory, recurse, symlink and absent functions.

file.directory
    Make sure that a directory exists and has the right permissions.

    /srv/foo:
      file:
        - directory
        - user: root
        - group: root
        - mode: 1755

file.symlink
    Make a symlink.

    /var/lib/www:
      file:
        - symlink
        - target: /srv/www
        - force: True

file.recurse
    The recurse state function will recursively download a directory on the master file server and place it on the minion. Any change in the files on the master will be pushed to the minion. The recurse function is very powerful and has been tested by pushing out the full Linux kernel source.

    /opt/code:
      file:
        - recurse
        - source: salt://linux

file.absent
    Make sure that the file is not on the system, recursively deletes directories, files and symlinks.

    /etc/httpd/conf.d/somebogusfile.conf:
      file:
        - absent

  Sysctl Module and State

The sysctl module and state allows for sysctl components in the kernel to be managed easily. the sysctl module contains the following functions:

sysctl.show
    Return a list of sysctl parameters for this minion

sysctl.get
    Return a single sysctl parameter for this minion

sysctl.assign
    Assign a single sysctl parameter for this minion

sysctl.persist
    Assign and persist a simple sysctl parameter for this minion

    The sysctl state allows for sysctl parameters to be assigned:

    vm.swappiness:
      sysctl:
        - present
        - value: 20

  Kernel Module Management

A module for managing Linux kernel modules has been added. The new functions are as follows:

kmod.available
    Return a list of all available kernel modules

kmod.check_available
    Check to see if the specified kernel module is available

kmod.lsmod
    Return a dict containing information about currently loaded modules

kmod.load
    Load the specified kernel module

kmod.remove
    Unload the specified kernel module

    The kmod state can enforce modules be either present or absent:

    kvm_intel:
      kmod:
        - present

  Ssh Authorized Keys

The ssh_auth state can distribute ssh authorized keys out to minions. Ssh authorized keys can be present or absent.

 :
  ssh_auth:
    - present
    - user: frank
    - enc: dsa
    - comment: 'Frank's key'

  Salt 0.9.4 Release Notes

Salt 0.9.4 has arrived. This is a critical update that repairs a number of key bugs found in 0.9.3. But this update is not without feature additions as well! 0.9.4 adds support for Gentoo portage to the pkg module and state system. Also there are 2 major new state additions, the failhard option and the ability to set up finite state ordering with the order option.

This release also sees our largest increase in community contributions. These contributors have and continue to be the life blood of the Salt project, and the team continues to grow. I want to put out a big thanks to our new and existing contributors.

  Download!

The Salt source can be downloaded from the salt github site:

https://github.com/downloads/saltstack/salt/salt-0.9.4.tar.gz

Or from PyPI:

http://pypi.python.org/packages/source/s/salt/salt-0.9.4.tar.gz

For instructions on how to set up Salt please see the installation instructions.

  New Features

  Failhard State Option

Normally, when a state fails Salt continues to execute the remainder of the defined states and will only refuse to execute states that require the failed state.

But the situation may exist, where you would want all state execution to stop if a single state execution fails. The capability to do this is called failing hard.

  State Level Failhard

A single state can have a failhard set, this means that if this individual state fails that all state execution will immediately stop. This is a great thing to do if there is a state that sets up a critical config file and setting a require for each state that reads the config would be cumbersome. A good example of this would be setting up a package manager early on:

/etc/yum.repos.d/company.repo:
  file:
    - managed
    - source: salt://company/yumrepo.conf
    - user: root
    - group: root
    - mode: 644
    - order: 1
    - failhard: True

In this situation, the yum repo is going to be configured before other states, and if it fails to lay down the config file, than no other states will be executed.

  Global Failhard

It may be desired to have failhard be applied to every state that is executed, if this is the case, then failhard can be set in the master configuration file. Setting failhard in the master configuration file will result in failing hard when any minion gathering states from the master have a state fail.

This is NOT the default behavior, normally Salt will only fail states that require a failed state.

Using the global failhard is generally not recommended, since it can result in states not being executed or even checked. It can also be confusing to see states failhard if an admin is not actively aware that the failhard has been set.

To use the global failhard set failhard: True in the master configuration

  Finite Ordering of State Execution

When creating salt sls files, it is often important to ensure that they run in a specific order. While states will always execute in the same order, that order is not necessarily defined the way you want it.

A few tools exist in Salt to set up the correct state ordering, these tools consist of requisite declarations and order options.

  The Order Option

Before using the order option, remember that the majority of state ordering should be done with requisite statements, and that a requisite statement will override an order option.

The order option is used by adding an order number to a state declaration with the option order:

vim:
  pkg:
    - installed
    - order: 1

By adding the order option to 1 this ensures that the vim package will be installed in tandem with any other state declaration set to the order 1.

Any state declared without an order option will be executed after all states with order options are executed.

But this construct can only handle ordering states from the beginning. Sometimes you may want to send a state to the end of the line, to do this set the order to last:

vim:
  pkg:
    - installed
    - order: last

Substantial testing has gone into the state system and it is ready for real world usage. A great deal has been added to the documentation for states and the modules and functions available to states have been cleanly documented.

A number of State System bugs have also been founds and repaired, the output from the state system has also been refined to be extremely clear and concise.

Error reporting has also been introduced, issues found in sls files will now be clearly reported when executing Salt States.

  Gentoo Support

Additional experimental support has been added for Gentoo. This is found in the contribution from Doug Renn, aka nestegg.

  Salt 0.9.5 Release Notes

Salt 0.9.5 is one of the largest steps forward in the development of Salt.

0.9.5 comes with many milestones, this release has seen the community of developers grow out to an international team of 46 code contributors and has many feature additions, feature enhancements, bug fixes and speed improvements.

Warning
    Be sure to read the upgrade instructions about the switch to msgpack before upgrading!

  Community

Nothing has proven to have more value to the development of Salt that the outstanding community that has been growing at such a great pace around Salt. This has proven not only that Salt has great value, but also the expandability of Salt is as exponential as I originally intended.

  Major Features

  SPEED! Pickle to msgpack

For a few months now we have been talking about moving away from Python pickles for network serialization, but a preferred serialization format had not yet been found. After an extensive performance testing period involving everything from JSON to protocol buffers, a clear winner emerged. Message Pack (http://msgpack.org/) proved to not only be the fastest and most compact, but also the most "salt like". Message Pack is simple, and the code involved is very small. The msgpack library for Python has been added directly to Salt.

This move introduces a few changes to Salt. First off, Salt is no longer a "noarch" package, since the msgpack lib is written in C. Salt 0.9.5 will also have compatibility issues with 0.9.4 with the default configuration.

We have gone through great lengths to avoid backwards compatibility issues with Salt, but changing the serialization medium was going to create issues regardless. Salt 0.9.5 is somewhat backwards compatible with earlier minions. A 0.9.5 master can command older minions, but only if the serial config value in the master is set to pickle. This will tell the master to publish messages in pickle format and will allow the master to receive messages in both msgpack and pickle formats.

Therefore the suggested methods for upgrading are either to just upgrade everything at once, or:

1.  Upgrade the master to 0.9.5

2.  Set serial to pickle in the master config

3.  Upgrade the minions

4.  Remove the serial option from the master config

    Since pickles can be used as a security exploit the ability for a master to accept pickles from minions at all will be removed in a future release.

  C Bindings for YAML

All of the YAML rendering is now done with the YAML C bindings. This speeds up all of the sls files when running states.

  Experimental Windows Support

David Boucha has worked tirelessly to bring initial support to Salt for Microsoft Windows operating systems. Right now the Salt Minion can run as a native Windows service and accept commands.

In the weeks and months to come Windows will receive the full treatment and will have support for Salt States and more robust support for managing Windows systems. This is a big step forward for Salt to move entirely outside of the Unix world, and proves Salt is a viable cross platform solution. Big Thanks to Dave for his contribution here!

  Dynamic Module Distribution

Many Salt users have expressed the desire to have Salt distribute in-house modules, states, renderers, returners, and grains. This support has been added in a number of ways:

  Modules via States

Now when salt modules are deployed to a minion via the state system as a file, then the modules will be automatically loaded into the active running minion - no restart required - and into the active running state. So custom state modules can be deployed and used in the same state run.

  Modules via Module Environment Directories

Under the file_roots each environment can now have directories that are used to deploy large groups of modules. These directories sync modules at the beginning of a state run on the minion, or can be manually synced via the Salt module salt.modules.saltutil.sync_all.

The directories are named:

•   _modules

•   _states

•   _grains

•   _renderers

•   _returners

    The modules are pushed to their respective scopes on the minions.

  Module Reloading

Modules can now be reloaded without restarting the minion, this is done by calling the salt.modules.sys.reload_modules function.

But wait, there's more! Now when a salt module of any type is added via states the modules will be automatically reloaded, allowing for modules to be laid down with states and then immediately used.

Finally, all modules are reloaded when modules are dynamically distributed from the salt master.

  Enable / Disable Added to Service

A great deal of demand has existed for adding the capability to set services to be started at boot in the service module. This feature also comes with an overhaul of the service modules and initial systemd support.

This means that the service state can now accept - enable: True to make sure a service is enabled at boot, and - enable: False to make sure it is disabled.

  Compound Target

A new target type has been added to the lineup, the compound target. In previous versions the desired minions could only be targeted via a single specific target type, but now many target specifications can be declared.

These targets can also be separated by and/or operators, so certain properties can be used to omit a node:

salt -C 'webserv* and G@os:Debian or E@db.*' test.ping

will match all minions with ids starting with webserv via a glob and minions matching the os:Debian grain. Or minions that match the db.* regular expression.

  Node Groups

Often the convenience of having a predefined group of minions to execute targets on is desired. This can be accomplished with the new nodegroups feature. Nodegroups allow for predefined compound targets to be declared in the master configuration file:

nodegroups:
  group1: 'L@foo.domain.com,bar.domain.com,baz.domain.com and bl*.domain.com'
  group2: 'G@os:Debian and foo.domain.com'

And then used via the -N option:

salt -N group1 test.ping

  Minion Side Data Store

The data module introduces the initial approach into storing persistent data on the minions, specific to the minions. This allows for data to be stored on minions that can be accessed from the master or from the minion.

The Minion datastore is young, and will eventually provide an interface similar to a more mature key/value pair server.

  Major Grains Improvement

The Salt grains have been overhauled to include a massive amount of extra data. this includes hardware data, os data and salt specific data.

  Salt -Q is Useful Now

In the past the salt query system, which would display the data from recent executions would be displayed in pure Python, and it was unreadable.

0.9.5 has added the outputter system to the -Q option, thus enabling the salt query system to return readable output.

  Packaging Updates

Huge strides have been made in packaging Salt for distributions. These additions are thanks to our wonderful community where the work to set up packages has proceeded tirelessly.

  FreeBSD

Salt on FreeBSD? There a port for that:

http://www.freebsd.org/cgi/cvsweb.cgi/ports/sysutils/salt/pkg-descr

This port was developed and added by Christer Edwards. This also marks the first time Salt has been included in an upstream packaging system!

  Fedora and Red Hat Enterprise

Salt packages have been prepared for inclusion in the Fedora Project and in EPEL for Red Hat Enterprise 5 and 6. These packages are the result of the efforts made by Clint Savage (herlo).

  Debian/Ubuntu

A team of many contributors have assisted in developing packages for Debian and Ubuntu. Salt is still actively seeking inclusion in upstream Debian and Ubuntu and the package data that has been prepared is being pushed through the needed channels for inclusion.

These packages have been prepared with the help of:

•   Corey

•   Aaron Toponce

•   and`

  More to Come

We are actively seeking inclusion in more distributions. Primarily getting Salt into Gentoo, SUSE, OpenBSD and preparing Solaris support are all turning into higher priorities.

  Refinement

Salt continues to be refined into a faster, more stable and more usable application. 0.9.5 comes with more debug logging, more bug fixes and more complete support.

  More Testing, More BugFixes

0.9.5 comes with more bugfixes due to more testing than any previous release. The growing community and the introduction a a dedicated QA environment have unearthed many issues that were hiding under the covers. This has further refined and cleaned the state interface, taking care of things from minor visual issues to repairing misleading data.

  Custom Exceptions

A custom exception module has been added to throw salt specific exceptions. This allows Salt to give much more granular error information.

  New Modules

  data

The new data module manages a persistent datastore on the minion. Big thanks to bastichelaar for his help refining this module

  freebsdkmod

FreeBSD kernel modules can now be managed in the same way Salt handles Linux kernel modules.

This module was contributed thanks to the efforts of Christer Edwards

  gentoo_service

Support has been added for managing services in Gentoo. Now Gentoo services can be started, stopped, restarted, enabled, disabled and viewed.

  pip

The pip module introduces management for pip installed applications. Thanks goes to whitinge for the addition of the pip module

  rh_service

The rh_service module enables Red Hat and Fedora specific service management. Now Red Hat like systems come with extensive management of the classic init system used by Red Hat

  saltutil

The saltutil module has been added as a place to hold functions used in the maintenance and management of salt itself. Saltutil is used to salt the salt minion. The saltutil module is presently used only to sync extension modules from the master server.

  systemd

Systemd support has been added to Salt, now systems using this next generation init system are supported on systems running systemd.

  virtualenv

The virtualenv module has been added to allow salt to create virtual Python environments. Thanks goes to whitinge for the addition of the virtualenv module

  win_disk

Support for gathering disk information on Microsoft Windows minions The windows modules come courtesy of Utah_Dave

  win_service

The win_service module adds service support to Salt for Microsoft Windows services

  win_useradd

Salt can now manage local users on Microsoft Windows Systems

  yumpkg5

The yumpkg module introduces in 0.9.4 uses the yum API to interact with the yum package manager. Unfortunately, on Red Hat 5 systems salt does not have access to the yum API because the yum API is running under Python 2.4 and Salt needs to run under Python 2.6.

The yumpkg5 module bypasses this issue by shelling out to yum on systems where the yum API is not available.

  New States

  mysql_database

The new mysql_database state adds the ability to systems running a mysql server to manage the existence of mysql databases.

The mysql states are thanks to syphernl

  mysql_user

The mysql_user state enables mysql user management.

  virtualenv

The virtualenv state can manage the state of Python virtual environments. Thanks to Whitinge for the virtualenv state

  New Returners

  cassandra_returner

A returner allowing Salt to send data to a cassandra server. Thanks to Byron Clark for contributing this returner

  Salt 0.9.6 Release Notes

Salt 0.9.6 is a release targeting a few bugs and changes. This is primarily targeting an issue found in the names declaration in the state system. But a few other bugs were also repaired, like missing support for grains in extmods.

Due to a conflict in distribution packaging msgpack will no longer be bundled with Salt, and is required as a dependency.

  New Features

  HTTP and ftp support in files.managed

Now under the source option in the file.managed state a HTTP or ftp address can be used instead of a file located on the salt master.

  Allow Multiple Returners

Now the returner interface can define multiple returners, and will also return data back to the master, making the process less ambiguous.

  Minion Memory Improvements

A number of modules have been taken out of the minion if the underlying systems required by said modules are not present on the minion system. A number of other modules need to be stripped out in this same way which should continue to make the minion more efficient.

  Minions Can Locally Cache Return Data

A new option, cache_jobs, has been added to the minion to allow for all of the historically run jobs to cache on the minion, allowing for looking up historic returns. By default cache_jobs is set to False.

  Pure Python Template Support For file.managed

Templates in the file.managed state can now be defined in a Python script. This script needs to have a run function that returns the string that needs to be in the named file.

  Salt 0.9.7 Release Notes

Salt 0.9.7 is here! The latest iteration of Salt brings more features and many fixes. This release is a great refinement over 0.9.6, adding many conveniences under the hood, as well as some features that make working with Salt much better.

A few highlights include the new Job system, refinements to the requisite system in states, the mod_init interface for states, external node classification, search path to managed files in the file state, and refinements and additions to dynamic module loading.

0.9.7 also introduces the long developed (and oft changed) unit test framework and the initial unit tests.

  Major Features

  Salt Jobs Interface

The new jobs interface makes the management of running executions much cleaner and more transparent. Building on the existing execution framework the jobs system allows clear introspection into the active running state of the running Salt interface.

The Jobs interface is centered in the new minion side proc system. The minions now store msgpack serialized files under /var/cache/salt/proc. These files keep track of the active state of processes on the minion.

  Functions in the saltutil Module

A number of functions have been added to the saltutil module to manage and view the jobs:

running - Returns the data of all running jobs that are found in the proc directory.

find_job - Returns specific data about a certain job based on job id.

signal_job - Allows for a given jid to be sent a signal.

term_job - Sends a termination signal (SIGTERM, 15) to the process controlling the specified job.

kill_job Sends a kill signal (SIGKILL, 9) to the process controlling the specified job.

  The jobs Runner

A convenience runner front end and reporting system has been added as well. The jobs runner contains functions to make viewing data easier and cleaner.

The jobs runner contains a number of functions...

  active

The active function runs saltutil.running on all minions and formats the return data about all running jobs in a much more usable and compact format. The active function will also compare jobs that have returned and jobs that are still running, making it easier to see what systems have completed a job and what systems are still being waited on.

  lookup_jid

When jobs are executed the return data is sent back to the master and cached. By default is is cached for 24 hours, but this can be configured via the keep_jobs option in the master configuration.

Using the lookup_jid runner will display the same return data that the initial job invocation with the salt command would display.

  list_jobs

Before finding a historic job, it may be required to find the job id. list_jobs will parse the cached execution data and display all of the job data for jobs that have already, or partially returned.

  External Node Classification

Salt can now use external node classifiers like Cobbler's cobbler-ext-nodes.

Salt uses specific data from the external node classifier. In particular the classes value denotes which sls modules to run, and the environment value sets to another environment.

An external node classification can be set in the master configuration file via the external_nodes option: http://salt.readthedocs.org/en/latest/ref/configuration/master.html#external-nodes

External nodes are loaded in addition to the top files. If it is intended to only use external nodes, do not deploy any top files.

  State Mod Init System

An issue arose with the pkg state. Every time a package was run Salt would need to refresh the package database. This made systems with slower package metadata refresh speeds much slower to work with. To alleviate this issue the mod_init interface has been added to salt states.

The mod_init interface is a function that can be added to a state file. This function is called with the first state called. In the case of the pkg state, the mod_init function sets up a tag which makes the package database only refresh on the first attempt to install a package.

In a nutshell, the mod_init interface allows a state to run any command that only needs to be run once, or can be used to set up an environment for working with the state.

  Source File Search Path

The file state continues to be refined, adding speed and capabilities. This release adds the ability to pass a list to the source option. This list is then iterated over until the source file is found, and the first found file is used.

The new syntax looks like this:

/etc/httpd/conf/httpd.conf:
  file:
    - managed
    - source:
      - salt://httpd/httpd.conf
      - http://myserver/httpd.conf: md5=8c1fe119e6f1fd96bc06614473509bf1

The source option can take sources in the list from the salt file server as well as an arbitrary web source. If using an arbitrary web source the checksum needs to be passed as well for file verification.

  Refinements to the Requisite System

A few discrepancies were still lingering in the requisite system, in particular, it was not possible to have a require and a watch requisite declared in the same state declaration.

This issue has been alleviated, as well as making the requisite system run more quickly.

  Initial Unit Testing Framework

Because of the module system, and the need to test real scenarios, the development of a viable unit testing system has been difficult, but unit testing has finally arrived. Only a small amount of unit testing coverage has been developed, much more coverage will be in place soon.

A huge thanks goes out to those who have helped with unit testing, and the contributions that have been made to get us where we are. Without these contributions unit tests would still be in the dark.

  Compound Targets Expanded

Originally only support for and and or were available in the compound target. 0.9.7 adds the capability to negate compound targets with not.

  Nodegroups in the Top File

Previously the nodegroups defined in the master configuration file could not be used to match nodes for states. The nodegroups support has been expanded and the nodegroups defined in the master configuration can now be used to match minions in the top file.

  Salt 0.9.8 Release Notes

Salt 0.9.8 is a big step forward, with many additions and enhancements, as well as a number of precursors to advanced future developments.

This version of Salt adds much more power to the command line, making the old hard timeout issues a thing of the past and adds keyword argument support. These additions are also available in the salt client API, making the available API tools much more powerful.

The new pillar system allows for data to be stored on the master and assigned to minions in a granular way similar to the state system. It also allows flexibility for users who want to keep data out of their state tree similar to 'external lookup' functionality in other tools.

A new way to extend requisites was added, the "requisite in" statement. This makes adding requires or watch statements to external state decs much easier.

Additions to requisites making them much more powerful have been added as well as improved error checking for sls files in the state system. A new provider system has been added to allow for redirecting what modules run in the background for individual states.

Support for OpenSUSE has been added and support for Solaris has begun serious development. Windows support has been significantly enhanced as well.

The matcher and target systems have received a great deal of attention. The default behavior of grain matching has changed slightly to reflect the rest of salt and the compound matcher system has been refined.

A number of impressive features with keyword arguments have been added to both the CLI and to the state system. This makes states much more powerful and flexible while maintaining the simple configuration everyone loves.

The new batch size capability allows for executions to be rolled through a group of targeted minions a percentage or specific number at a time. This was added to prevent the "thundering herd" problem when targeting large numbers of minions for things like service restarts or file downloads.

  Upgrade Considerations

  Upgrade Issues

There was a previously missed oversight which could cause a newer minion to crash an older master. That oversight has been resolved so the version incompatibility issue will no longer occur. When upgrading to 0.9.8 make sure to upgrade the master first, followed by the minions.

  Debian/Ubuntu Packages

The original Debian/Ubuntu packages were called salt and included all salt applications. New packages in the ppa are split by function. If an old salt package is installed then it should be manually removed and the new split packages need to be freshly installed.

On the master:

# apt-get purge salt
# apt-get install salt-{master,minion}

On the minions:

# apt-get purge salt
# apt-get install salt-minion

And on any Syndics:

# apt-get install salt-syndic

The official salt stack ppa for Ubuntu is located at: https://launchpad.net/~saltstack/+archive/salt

  Major Features

  Pillar

Pillar offers an interface to declare variable data on the master that is then assigned to the minions. The pillar data is made available to all modules, states, sls files etc. It is compiled on the master and is declared using the existing renderer system. This means that learning pillar should be fairly trivial to those already familiar with salt states.

  CLI Additions

The salt command has received a serious overhaul and is more powerful than ever. Data is returned to the terminal as it is received, and the salt command will now wait for all running minions to return data before stopping. This makes adding very large --timeout arguments completely unnecessary and gets rid of long running operations returning empty {} when the timeout is exceeded.

When calling salt via sudo, the user originally running salt is saved to the log for auditing purposes. This makes it easy to see who ran what by just looking through the minion logs.

The salt-key command gained the -D and --delete-all arguments for removing all keys. Be careful with this one!

  Running States Without a Master

The addition of running states without a salt-master has been added to 0.9.8. This feature allows for the unmodified salt state tree to be read locally from a minion. The result is that the UNMODIFIED state tree has just become portable, allowing minions to have a local copy of states or to manage states without a master entirely.

This is accomplished via the new file client interface in Salt that allows for the salt:// URI to be redirected to custom interfaces. This means that there are now two interfaces for the salt file server, calling the master or looking in a local, minion defined file_roots.

This new feature can be used by modifying the minion config to point to a local file_roots and setting the file_client option to local.

  Keyword Arguments and States

State modules now accept the **kwargs argument. This results in all data in a sls file assigned to a state being made available to the state function.

This passes data in a transparent way back to the modules executing the logic. In particular, this allows adding arguments to the pkg.install module that enable more advanced and granular controls with respect to what the state is capable of.

An example of this along with the new debconf module for installing ldap client packages on Debian:

ldap-client-packages:
  pkg:
    - debconf: salt://debconf/ldap-client.ans
    - installed
    - names:
      - nslcd
      - libpam-ldapd
      - libnss-ldapd

  Keyword Arguments and the CLI

In the past it was required that all arguments be passed in the proper order to the salt and salt-call commands. As of 0.9.8, keyword arguments can be passed in the form of kwarg=argument.

# salt -G 'type:dev' git.clone \
    repository=https://github.com/saltstack/salt.git cwd=/tmp/salt user=jeff

  Matcher Refinements and Changes

A number of fixes and changes have been applied to the Matcher system. The most noteworthy is the change in the grain matcher. The grain matcher used to use a regular expression to match the passed data to a grain, but now defaults to a shell glob like the majority of match interfaces in Salt. A new option is available that still uses the old style regex matching to grain data called grain-pcre. To use regex matching in compound matches use the letter P.

For example, this would match any ArchLinux or Fedora minions:

# salt --grain-pcre 'os:(Arch:Fed).*' test.ping

And the associated compound matcher suitable for top.sls is P:

P@os:(Arch|Fed).*

NOTE: Changing the grains matcher from pcre to glob is backwards incompatible.

Support has been added for matching minions with Yahoo's range library. This is handled by passing range syntax with -R or --range arguments to salt.

More information at: https://github.com/grierj/range/wiki/Introduction-to-Range-with-YAML-files

  Requisite in

A new means to updating requisite statements has been added to make adding watchers and requires to external states easier. Before 0.9.8 the only way to extend the states that were watched by a state outside of the sls was to use an extend statement:

include:
  - http
extend:
  apache:
    service:
      - watch:
        - pkg: tomcat
tomcat:
  pkg:
    - installed

But the new Requisite in statement allows for easier extends for requisites:

include:
  - http
tomcat:
  pkg:
    - installed
    - watch_in:
      - service: apache

Requisite in is part of the extend system, so still remember to always include the sls that is being extended!

  Providers

Salt predetermines what modules should be mapped to what uses based on the properties of a system. These determinations are generally made for modules that provide things like package and service management. The apt module maps to pkg on Debian and the yum module maps to pkg on Fedora for instance.

Sometimes in states, it may be necessary for a non-default module to be used for the desired functionality. For instance, an Arch Linux system may have been set up with systemd support. Instead of using the default service module detected for Arch Linux, the systemd module can be used:

http:
  service:
    - running
    - enable: True
    - provider: systemd

Default providers can also be defined in the minion config file:

providers:
  pkg: yumpkg5
  service: systemd

When default providers are passed in the minion config, then those providers will be applied to all functionality in Salt, this means that the functions called by the minion will use these modules, as well as states.

  Requisite Glob Matching

Requisites can now be defined with glob expansion. This means that if there are many requisites, they can be defined on a single line.

To watch all files in a directory:

http:
  service:
    - running
    - enable: True
    - watch:
      - file: /etc/http/conf.d/*

This example will watch all defined files that match the glob /etc/http/conf.d/*

  Batch Size

The new batch size option allows commands to be executed while maintaining that only so many hosts are executing the command at one time. This option can take a percentage or a finite number:

salt \* -b 10 test.ping
salt -G 'os:RedHat' --batch-size 25% apache.signal restart

This will only run test.ping on 10 of the targeted minions at a time and then restart apache on 25% of the minions matching os:RedHat at a time and work through them all until the task is complete. This makes jobs like rolling web server restarts behind a load balancer or doing maintenance on BSD firewalls using carp much easier with salt.

  Module Updates

This is a list of notable, but non-exhaustive updates with new and existing modules.

Windows support has seen a flurry of support this release cycle. We've gained all new file, network, and shadow modules. Please note that these are still a work in progress.

For our ruby users, new rvm and gem modules have been added along with the associated states

The virt module gained basic Xen support.

The yum pkg modules gained Scientific Linux support.

The pkg module on Debian, Ubuntu, and derivatives force apt to run in a non-interactive mode. This prevents issues when package installation waits for confirmation.

A pkg module for OpenSUSE's zypper was added.

The service module on Ubuntu natively supports upstart.

A new debconf module was contributed by our community for more advanced control over deb package deployments on Debian based distributions.

The mysql.user state and mysql module gained a password_hash argument.

The cmd module and state gained a shell keyword argument for specifying a shell other than /bin/sh on Linux / Unix systems.

New git and mercurial modules have been added for fans of distributed version control.

  In Progress Development

  Master Side State Compiling

While we feel strongly that the advantages gained with minion side state compiling are very critical, it does prevent certain features that may be desired. 0.9.8 has support for initial master side state compiling, but many more components still need to be developed, it is hoped that these can be finished for 0.9.9.

The goal is that states can be compiled on both the master and the minion allowing for compilation to be split between master and minion. Why will this be great? It will allow storing sensitive data on the master and sending it to some minions without all minions having access to it. This will be good for handling ssl certificates on front-end web servers for instance.

  Solaris Support

Salt 0.9.8 sees the introduction of basic Solaris support. The daemon runs well, but grains and more of the modules need updating and testing.

  Windows Support

Salt states on windows are now much more viable thanks to contributions from our community! States for file, service, local user, and local group management are more fully fleshed out along with network and disk modules. Windows users can also now manage registry entries using the new "reg" module.

  Salt 0.9.9 Release Notes

0.9.9 is out and comes with some serious bug fixes and even more serious features. This release is the last major feature release before 1.0.0 and could be considered the 1.0.0 release candidate.

A few updates include more advanced kwargs support, the ability for salt states to more safely configure a running salt minion, better job directory management and the new state test interface.

Many new tests have been added as well, including the new minion swarm test that allows for easier testing of Salt working with large groups of minions. This means that if you have experienced stability issues with Salt before, particularly in larger deployments, that these bugs have been tested for, found, and killed.

  Major Features

  State Test Interface

Until 0.9.9 the only option when running states to see what was going to be changed was to print out the highstate with state.show_highstate and manually look it over. But now states can be run to discover what is going to be changed.

Passing the option test=True to many of the state functions will now cause the salt state system to only check for what is going to be changed and report on those changes.

# salt \* state.highstate test=True

Now states that would have made changes report them back in yellow.

  State Syntax Update

A shorthand syntax has been added to sls files, and it will be the default syntax in documentation going forward. The old syntax is still fully supported and will not be deprecated, but it is recommended to move to the new syntax in the future. This change moves the state function up into the state name using a dot notation. This is in-line with how state functions are generally referred to as well:

The new way:

/etc/sudoers:
  file.present:
    - source: salt://sudo/sudoers
    - user: root
    - mode: 400

  Use and Use_in Requisites

Two new requisite statements are available in 0.9.9. The use and use_in requisite and requisite-in allow for the transparent duplication of data between states. When a state "uses" another state it copies the other state's arguments as defaults. This was created in direct response to the new network state, and allows for many network interfaces to be configured in the same way easily. A simple example:

root_file:
  file.absent:
    - name: /tmp/nothing
    - user: root
    - mode: 644
    - group: root
    - use_in:
      - file: /etc/vimrc
fred_file:
  file.absent:
    - name: /tmp/nothing
    - user: fred
    - group: marketing
    - mode: 660
/files/marketing/district7.rst:
  file.present:
    - source: salt://marketing/district7.rst
    - template: jinja
    - use:
      - file: fred_file
/etc/vimrc:
  file.present:
    - source: salt://edit/vimrc

This makes the 2 lower state decs inherit the options from their respectively "used" state decs.

  Network State

The new network state allows for the configuration of network devices via salt states and the ip salt module. This addition has been given to the project by Jeff Hutchins and Bret Palsson from Jive Communications.

Currently the only network configuration backend available is for Red Hat based systems, like Red Hat Enterprise, CentOS, and Fedora.

  Exponential Jobs

Originally the jobs executed were stored on the master in the format: <cachedir>/jobs/jid/{minion ids} But this format restricted the number of jobs in the cache to the number of subdirectories allowed on the filesystem. Ext3 for instance limits subdirectories to 32000. To combat this the new format for 0.9.9 is: <cachedir>/jobs/jid_hash[:2]/jid_hash[2:]/{minion ids} So that now the number of maximum jobs that can be run before the cleanup cycle hits the job directory is substantially higher.

  ssh_auth Additions

The original ssh_auth state was limited to accepting only arguments to apply to a public key, and the key itself. This was restrictive due to the way the we learned that many people were using the state, so the key section has been expanded to accept options and arguments to the key that over ride arguments passed in the state. This gives substantial power to using ssh_auth with names:

sshkeys:
  ssh_auth:
    - present
    - user: backup
    - enc: ssh-dss
    - options:
      - option1="value1"
      - option2="value2 flag2"
    - comment: backup
    - names:

  LocalClient Additions

To follow up the recent additions in 0.9.8 of additional kwargs support, 0.9.9 also adds the capability to send kwargs into commands via a dict. This addition to the LocalClient api can be used like so:

import salt.client
client = salt.client.LocalClient('/etc/salt/master')
ret = client.cmd('*', 'cmd.run', ['ls -l'], kwarg={'cwd': '/etc'})

This update has been added to all cmd methods in the LocalClient class.

  Better Self Salting

One problem faced with running Salt states, is that it has been difficult to manage the Salt minion via states, this is due to the fact that if the minion is called to restart while a state run is happening then the state run would be killed. 0.9.9 slightly changes the process scope of the state runs, so now when salt is executing states it can safely restart the salt-minion daemon.

In addition to daemonizing the state run, the apt module also daemonizes. This update makes it possible to cleanly update the salt-minion package on Debian/Ubuntu systems without leaving apt in an inconsistent state or killing the active minion process mid-execution.

  Wildcards for SLS Modules

Now, when including sls modules in include statements or in the top file, shell globs can be used. This can greatly simplify listing matched sls modules in the top file and include statements:

base:
  '*':
    - files*
    - core*

include:
  - users.dev.*
  - apache.ser*

  External Pillar

Since the pillar data is just, data, it does not need to come expressly from the pillar interface. The external pillar system allows for hooks to be added making it possible to extract pillar data from any arbitrary external interface. The external pillar interface is configured via the ext_pillar option. Currently interfaces exist to gather external pillar data via hiera or via a shell command that sends yaml data to the terminal:

ext_pillar:
  - cmd_yaml: cat /etc/salt/ext.yaml
  - hiera: /etc/hirea.yaml

The initial external pillar interfaces and extra interfaces can be added to the file salt/pillar.py, it is planned to add more external pillar interfaces. If the need arises a new module loader interface will be created in the future to manage external pillar interfaces.

  Single State Executions

The new state.single function allows for single states to be cleanly executed. This is a great tool for setting up a small group of states on a system or for testing out the behavior of single states:

# salt \* state.single user.present name=wade uid=2000

The test interface functions here as well, so changes can also be tested against as:

# salt \* state.single user.present name=wade uid=2000 test=True

  New Tests

A few exciting new test interfaces have been added, the minion swarm allows not only testing of larger loads, but also allows users to see how Salt behaves with large groups of minions without having to create a large deployment.

  Minion Swarm

The minion swarm test system allows for large groups of minions to be tested against easily without requiring large numbers of servers or virtual machines. The minion swarm creates as many minions as a system can handle and roots them in the /tmp directory and connects them to a master.

The benefit here is that we were able to replicate issues that happen only when there are large numbers of minions. A number of elusive bugs which were causing stability issues in masters and minions have since been hunted down. Bugs that used to take careful watch by users over several days can now be reliably replicated in minutes, and fixed in minutes.

Using the swarm is easy, make sure a master is up for the swarm to connect to, and then use the minionswarm.py script in the tests directory to spin up as many minions as you want. Remember, this is a fork bomb, don't spin up more than your hardware can handle!

# python minionswarm.py -m 20 --master salt-master

  Shell Tests

The new Shell testing system allows us to test the behavior of commands executed from a high level. This allows for the high level testing of salt runners and commands like salt-key.

  Client Tests

Tests have been added to test the aspects of the client APIs and ensure that the client calls work, and that they manage passed data, in a desirable way.
