## TL;DR

```console
helm install my-release oci://registry-1.docker.io/bitnamicharts/postgresql
```

Looking to use PostgreSQL in production? Try [VMware Tanzu Application Catalog](https://bitnami.com/enterprise), the enterprise edition of Bitnami Application Catalog.

## Introduction

This chart bootstraps a [PostgreSQL](https://github.com/bitnami/containers/tree/main/bitnami/postgresql) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

For HA, please see [this repo](https://github.com/bitnami/charts/tree/main/bitnami/postgresql-ha)

Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.

## Prerequisites

- Kubernetes 1.23+
- Helm 3.8.0+
- PV provisioner support in the underlying infrastructure

## Installing the Chart

To install the chart with the release name `my-release`:

```console
helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/postgresql
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

The command deploys PostgreSQL on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.

> **Tip**: List all releases using `helm list`

## Uninstalling the Chart

To uninstall/delete the `my-release` deployment:

```console
helm delete my-release
```

The command removes all the Kubernetes components but PVC's associated with the chart and deletes the release.

To delete the PVC's associated with `my-release`:

```console
kubectl delete pvc -l release=my-release
```

> **Note**: Deleting the PVC's will delete postgresql data as well. Please be cautious before doing it.

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```console
helm install my-release \
    --set auth.postgresPassword=secretpassword
    oci://REGISTRY_NAME/REPOSITORY_NAME/postgresql
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

The above command sets the PostgreSQL `postgres` account password to `secretpassword`.

> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.
> **Warning** Setting a password will be ignored on new installation in case when previous PostgreSQL release was deleted through the helm command. In that case, old PVC will have an old password, and setting it through helm won't take effect. Deleting persistent volumes (PVs) will solve the issue. Refer to [issue 2061](https://github.com/bitnami/charts/issues/2061) for more details

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

```console
helm install my-release -f values.yaml oci://REGISTRY_NAME/REPOSITORY_NAME/postgresql
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.
> **Tip**: You can use the default [values.yaml](https://github.com/bitnami/charts/tree/main/bitnami/postgresql/values.yaml)

## Configuration and installation details

### Resource requests and limits

Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the `resources` value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case.

To make this process easier, the chart contains the `resourcesPreset` values, which automatically sets the `resources` section according to different presets. Check these presets in [the bitnami/common chart](https://github.com/bitnami/charts/blob/main/bitnami/common/templates/_resources.tpl#L15). However, in production workloads using `resourcePreset` is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the [official Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/).

### [Rolling VS Immutable tags](https://docs.bitnami.com/tutorials/understand-rolling-tags-containers)

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

### Customizing primary and read replica services in a replicated configuration

At the top level, there is a service object which defines the services for both primary and readReplicas. For deeper customization, there are service objects for both the primary and read types individually. This allows you to override the values in the top level service object so that the primary and read can be of different service types and with different clusterIPs / nodePorts. Also in the case you want the primary and read to be of type nodePort, you will need to set the nodePorts to different values to prevent a collision. The values that are deeper in the primary.service or readReplicas.service objects will take precedence over the top level service object.

### Use a different PostgreSQL version

To modify the application version used in this chart, specify a different version of the image using the `image.tag` parameter and/or a different repository using the `image.repository` parameter.

### LDAP

LDAP support can be enabled in the chart by specifying the `ldap.` parameters while creating a release. The following parameters should be configured to properly enable the LDAP support in the chart.

- **ldap.enabled**: Enable LDAP support. Defaults to `false`.
- **ldap.uri**: LDAP URL beginning in the form `ldap[s]://<hostname>:<port>`. No defaults.
- **ldap.base**: LDAP base DN. No defaults.
- **ldap.binddn**: LDAP bind DN. No defaults.
- **ldap.bindpw**: LDAP bind password. No defaults.
- **ldap.bslookup**: LDAP base lookup. No defaults.
- **ldap.nss_initgroups_ignoreusers**: LDAP ignored users. `root,nslcd`.
- **ldap.scope**: LDAP search scope. No defaults.
- **ldap.tls_reqcert**: LDAP TLS check on server certificates. No defaults.

For example:

```text
ldap.enabled="true"
ldap.uri="ldap://my_ldap_server"
ldap.base="dc=example\,dc=org"
ldap.binddn="cn=admin\,dc=example\,dc=org"
ldap.bindpw="admin"
ldap.bslookup="ou=group-ok\,dc=example\,dc=org"
ldap.nss_initgroups_ignoreusers="root\,nslcd"
ldap.scope="sub"
ldap.tls_reqcert="demand"
```

Next, login to the PostgreSQL server using the `psql` client and add the PAM authenticated LDAP users.

> Note: Parameters including commas must be escaped as shown in the above example.

### postgresql.conf / pg_hba.conf files as configMap

This helm chart also supports to customize the PostgreSQL configuration file. You can add additional PostgreSQL configuration parameters using the `primary.extendedConfiguration`/`readReplicas.extendedConfiguration` parameters as a string. Alternatively, to replace the entire default configuration use `primary.configuration`.

You can also add a custom pg_hba.conf using the `primary.pgHbaConfiguration` parameter.

In addition to these options, you can also set an external ConfigMap with all the configuration files. This is done by setting the `primary.existingConfigmap` parameter. Note that this will override the two previous options.

### Initialize a fresh instance

The [Bitnami PostgreSQL](https://github.com/bitnami/containers/tree/main/bitnami/postgresql) image allows you to use your custom scripts to initialize a fresh instance. In order to execute the scripts, you can specify custom scripts using the `primary.initdb.scripts` parameter as a string.

In addition, you can also set an external ConfigMap with all the initialization scripts. This is done by setting the `primary.initdb.scriptsConfigMap` parameter. Note that this will override the two previous options. If your initialization scripts contain sensitive information such as credentials or passwords, you can use the `primary.initdb.scriptsSecret` parameter.

The allowed extensions are `.sh`, `.sql` and `.sql.gz`.

### Securing traffic using TLS

TLS support can be enabled in the chart by specifying the `tls.` parameters while creating a release. The following parameters should be configured to properly enable the TLS support in the chart:

- `tls.enabled`: Enable TLS support. Defaults to `false`
- `tls.certificatesSecret`: Name of an existing secret that contains the certificates. No defaults.
- `tls.certFilename`: Certificate filename. No defaults.
- `tls.certKeyFilename`: Certificate key filename. No defaults.

For example:

- First, create the secret with the cetificates files:

    ```console
    kubectl create secret generic certificates-tls-secret --from-file=./cert.crt --from-file=./cert.key --from-file=./ca.crt
    ```

- Then, use the following parameters:

    ```console
    volumePermissions.enabled=true
    tls.enabled=true
    tls.certificatesSecret="certificates-tls-secret"
    tls.certFilename="cert.crt"
    tls.certKeyFilename="cert.key"
    ```

  > Note TLS and VolumePermissions: PostgreSQL requires certain permissions on sensitive files (such as certificate keys) to start up. Due to an on-going [issue](https://github.com/kubernetes/kubernetes/issues/57923) regarding kubernetes permissions and the use of `containerSecurityContext.runAsUser`, you must enable `volumePermissions` to ensure everything works as expected.

### Sidecars

If you need  additional containers to run within the same pod as PostgreSQL (e.g. an additional metrics or logging exporter), you can do so via the `sidecars` config parameter. Simply define your container according to the Kubernetes container spec.

```yaml
# For the PostgreSQL primary
primary:
  sidecars:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
    - name: portname
     containerPort: 1234
# For the PostgreSQL replicas
readReplicas:
  sidecars:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
    - name: portname
     containerPort: 1234
```

### Metrics

The chart optionally can start a metrics exporter for [prometheus](https://prometheus.io). The metrics endpoint (port 9187) is not exposed and it is expected that the metrics are collected from inside the k8s cluster using something similar as the described in the [example Prometheus scrape configuration](https://github.com/prometheus/prometheus/blob/master/documentation/examples/prometheus-kubernetes.yml).

The exporter allows to create custom metrics from additional SQL queries. See the Chart's `values.yaml` for an example and consult the [exporters documentation](https://github.com/wrouesnel/postgres_exporter#adding-new-metrics-via-a-config-file) for more details.

### Use of global variables

In more complex scenarios, we may have the following tree of dependencies

```text
                     +--------------+
                     |              |
        +------------+   Chart 1    +-----------+
        |            |              |           |
        |            --------+------+           |
        |                    |                  |
        |                    |                  |
        |                    |                  |
        |                    |                  |
        v                    v                  v
+-------+------+    +--------+------+  +--------+------+
|              |    |               |  |               |
|  PostgreSQL  |    |  Sub-chart 1  |  |  Sub-chart 2  |
|              |    |               |  |               |
+--------------+    +---------------+  +---------------+
```

The three charts below depend on the parent chart Chart 1. However, subcharts 1 and 2 may need to connect to PostgreSQL as well. In order to do so, subcharts 1 and 2 need to know the PostgreSQL credentials, so one option for deploying could be deploy Chart 1 with the following parameters:

```text
postgresql.auth.username=testuser
subchart1.postgresql.auth.username=testuser
subchart2.postgresql.auth.username=testuser
postgresql.auth.password=testpass
subchart1.postgresql.auth.password=testpass
subchart2.postgresql.auth.password=testpass
postgresql.auth.database=testdb
subchart1.postgresql.auth.database=testdb
subchart2.postgresql.auth.database=testdb
```

If the number of dependent sub-charts increases, installing the chart with parameters can become increasingly difficult. An alternative would be to set the credentials using global variables as follows:

```text
global.postgresql.auth.username=testuser
global.postgresql.auth.password=testpass
global.postgresql.auth.database=testdb
```

This way, the credentials will be available in all of the subcharts.

### Persistence

The [Bitnami PostgreSQL](https://github.com/bitnami/containers/tree/main/bitnami/postgresql) image stores the PostgreSQL data and configurations at the `/bitnami/postgresql` path of the container.

Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube.
See the [Parameters](#parameters) section to configure the PVC or to disable persistence.

If you already have data in it, you will fail to sync to standby nodes for all commits, details can refer to the [code present in the container repository](https://github.com/bitnami/containers/tree/main/bitnami/postgresql). If you need to use those data, please covert them to sql and import after `helm install` finished.

### Backup and restore PostgreSQL deployments

To back up and restore Bitnami PostgreSQL Helm chart deployments on Kubernetes, you need to back up the persistent volumes from the source deployment and attach them to a new deployment using [Velero](https://velero.io/), a Kubernetes backup/restore tool.

These are the steps you will usually follow to back up and restore your PostgreSQL cluster data:

- Install Velero on the source and destination clusters.
- Use Velero to back up the PersistentVolumes (PVs) used by the deployment on the source cluster.
- Use Velero to restore the backed-up PVs on the destination cluster.
- Create a new deployment on the destination cluster with the same chart, deployment name, credentials and other parameters as the original. This new deployment will use the restored PVs and hence the original data.

Refer to our detailed [tutorial on backing up and restoring PostgreSQL deployments on Kubernetes](https://docs.bitnami.com/tutorials/migrate-data-bitnami-velero/) for more information.

### NetworkPolicy

To enable network policy for PostgreSQL, install [a networking plugin that implements the Kubernetes NetworkPolicy spec](https://kubernetes.io/docs/tasks/administer-cluster/declare-network-policy#before-you-begin), and set `networkPolicy.enabled` to `true`.

For Kubernetes v1.5 & v1.6, you must also turn on NetworkPolicy by setting the DefaultDeny namespace annotation. Note: this will enforce policy for _all_ pods in the namespace:

```console
kubectl annotate namespace default "net.beta.kubernetes.io/network-policy={\"ingress\":{\"isolation\":\"DefaultDeny\"}}"
```

With NetworkPolicy enabled, traffic will be limited to just port 5432.

For more precise policy, set `networkPolicy.allowExternal=false`. This will only allow pods with the generated client label to connect to PostgreSQL.
This label will be displayed in the output of a successful install.

### Differences between Bitnami PostgreSQL image and [Docker Official](https://hub.docker.com/_/postgres) image

- The Docker Official PostgreSQL image does not support replication. If you pass any replication environment variable, this would be ignored. The only environment variables supported by the Docker Official image are POSTGRES_USER, POSTGRES_DB, POSTGRES_PASSWORD, POSTGRES_INITDB_ARGS, POSTGRES_INITDB_WALDIR and PGDATA. All the remaining environment variables are specific to the Bitnami PostgreSQL image.
- The Bitnami PostgreSQL image is non-root by default. This requires that you run the pod with `securityContext` and updates the permissions of the volume with an `initContainer`. A key benefit of this configuration is that the pod follows security best practices and is prepared to run on Kubernetes distributions with hard security constraints like OpenShift.
- For OpenShift up to 4.10, let set the volume permissions, security context, runAsUser and fsGroup automatically by OpenShift and disable the predefined settings of the helm chart: primary.securityContext.enabled=false,primary.containerSecurityContext.enabled=false,volumePermissions.enabled=false,shmVolume.enabled=false
- For OpenShift 4.11 and higher, let set OpenShift the runAsUser and fsGroup automatically. Configure the pod and container security context to restrictive defaults and disable the volume permissions setup: primary.
    podSecurityContext.fsGroup=null,primary.podSecurityContext.seccompProfile.type=RuntimeDefault,primary.containerSecurityContext.runAsUser=null,primary.containerSecurityContext.allowPrivilegeEscalation=false,primary.containerSecurityContext.runAsNonRoot=true,primary.containerSecurityContext.seccompProfile.type=RuntimeDefault,primary.containerSecurityContext.capabilities.drop=['ALL'],volumePermissions.enabled=false,shmVolume.enabled=false

### Setting Pod's affinity

This chart allows you to set your custom affinity using the `XXX.affinity` parameter(s). Find more information about Pod's affinity in the [kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).

As an alternative, you can use of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/main/bitnami/common#affinities) chart. To do so, set the `XXX.podAffinityPreset`, `XXX.podAntiAffinityPreset`, or `XXX.nodeAffinityPreset` parameters.

## Upgrading

### To 14.0.0

This major version adapts the NetworkPolicy objects to the most recent Bitnami standards. Now there is a separate object for `primary` and for `readReplicas`, being located in their corresponding sections. It is also enabled by default in other to comply with the best security standards.

Check the parameter section for the new value structure.

### To 13.0.0

This major version changes the default PostgreSQL image from 15.x to 16.x. Follow the [official instructions](https://www.postgresql.org/docs/16/upgrading.html) to upgrade to 16.x.

### To 12.0.0

This major version changes the default PostgreSQL image from 14.x to 15.x. Follow the [official instructions](https://www.postgresql.org/docs/15/upgrading.html) to upgrade to 15.x.

### To 11.0.0

In this version the application version was bumped to _14.x_ series. Also, this major release renames several values in this chart and adds missing features, in order to be inline with the rest of assets in the Bitnami charts repository.

- _replication.enabled_ parameter is deprecated in favor of _architecture_ parameter that accepts two values: _standalone_ and _replication_.
- _replication.singleService_ and _replication.uniqueServices_ parameters are deprecated. When using replication, each statefulset (primary and read-only) has its own headless service & service allowing to connect to read-only replicas through the service (round-robin) or individually.
- _postgresqlPostgresPassword_, _postgresqlUsername_, _postgresqlPassword_, _postgresqlDatabase_, _replication.user_, _replication.password_, and _existingSecret_ parameters have been regrouped under the _auth_ map. The _auth_ map uses a new perspective to configure authentication, so please read carefully each sub-parameter description.
- _extraEnv_ has been deprecated in favor of _primary.extraEnvVars_ and _readReplicas.extraEnvVars_.
- _postgresqlConfiguration_, _pgHbaConfiguration_, _configurationConfigMap_, _postgresqlExtendedConf_, and _extendedConfConfigMap_ have been deprecated in favor of _primary.configuration_, _primary.pgHbaConfiguration_, _primary.existingConfigmap_, _primary.extendedConfiguration_, and _primary.existingExtendedConfigmap_.
- _postgresqlInitdbArgs_, _postgresqlInitdbWalDir_, _initdbScripts_, _initdbScriptsConfigMap_, _initdbScriptsSecret_, _initdbUser_ and _initdbPassword_ have been regrouped under the _primary.initdb_ map.
- _postgresqlMaxConnections_, _postgresqlPostgresConnectionLimit_, _postgresqlDbUserConnectionLimit_, _postgresqlTcpKeepalivesInterval_, _postgresqlTcpKeepalivesIdle_, _postgresqlTcpKeepalivesCount_, _postgresqlStatementTimeout_ and _postgresqlPghbaRemoveFilters_ parameters are deprecated. Use _XXX.extraEnvVars_ instead.
- _primaryAsStandBy_ has been deprecated in favor of _primary.standby_.
- _securityContext_ and _containerSecurityContext_ have been deprecated in favor of _primary.podSecurityContext_, _primary.containerSecurityContext_, _readReplicas.podSecurityContext_, and _readReplicas.containerSecurityContext_.
- _livenessProbe_ and _readinessProbe_ maps have been deprecated in favor of _primary.livenessProbe_, _primary.readinessProbe_, _readReplicas.livenessProbe_ and _readReplicas.readinessProbe_ maps.
- _persistence_ map has been deprecated in favor of _primary.persistence_ and _readReplicas.persistence_ maps.
- _networkPolicy_ map has been completely refactored.
- _service_ map has been deprecated in favor of _primary.service_ and _readReplicas.service_ maps.
- _metrics.service.port_ has been regrouped under the _metrics.service.ports_ map.
- _serviceAccount.enabled_ and _serviceAccount.autoMount_ have been deprecated in favor of _serviceAccount.create_ and _serviceAccount.automountServiceAccountToken_.

#### How to upgrade to version 11.0.0

To upgrade to _11.0.0_ from _10.x_, it should be done reusing the PVC(s) used to hold the PostgreSQL data on your previous release. To do so, follow the instructions below (the following example assumes that the release name is _postgresql_):

> NOTE: Please, create a backup of your database before running any of these actions.

1. Obtain the credentials and the names of the PVCs used to hold the PostgreSQL data on your current release:

```console
export POSTGRESQL_PASSWORD=$(kubectl get secret --namespace default postgresql -o jsonpath="{.data.postgresql-password}" | base64 --decode)
export POSTGRESQL_PVC=$(kubectl get pvc -l app.kubernetes.io/instance=postgresql,role=primary -o jsonpath="{.items[0].metadata.name}")
```

1. Delete the PostgreSQL statefulset (notice the option _--cascade=false_) and secret:

```console
kubectl delete statefulsets.apps postgresql-postgresql --namespace default --cascade=false
kubectl delete secret postgresql --namespace default
```

1. Upgrade your release using the same PostgreSQL version:

```console
CURRENT_VERSION=$(kubectl exec postgresql-postgresql-0 -- bash -c 'echo $BITNAMI_IMAGE_VERSION')
helm upgrade postgresql bitnami/postgresql \
  --set auth.postgresPassword=$POSTGRESQL_PASSWORD \
  --set primary.persistence.existingClaim=$POSTGRESQL_PVC \
  --set image.tag=$CURRENT_VERSION
```

1. You will have to delete the existing PostgreSQL pod and the new statefulset is going to create a new one

```console
kubectl delete pod postgresql-postgresql-0
```

1. Finally, you should see the lines below in PostgreSQL container logs:

```text
$ kubectl logs $(kubectl get pods -l app.kubernetes.io/instance=postgresql,app.kubernetes.io/name=postgresql,app.kubernetes.io/component=primary -o jsonpath="{.items[0].metadata.name}")
...
postgresql 08:05:12.59 INFO  ==> Deploying PostgreSQL with persisted data...
...
```

> NOTE: the instructions above reuse the same PostgreSQL version you were using in your chart release. Otherwise, you will find an error such as the one below when upgrading since the new chart major version also bumps the application version. To workaround this issue you need to upgrade database, please refer to the [official PostgreSQL documentation](https://www.postgresql.org/docs/current/upgrading.html) for more information about this.

```console
$ kubectl logs $(kubectl get pods -l app.kubernetes.io/instance=postgresql,app.kubernetes.io/name=postgresql,app.kubernetes.io/component=primary -o jsonpath="{.items[0].metadata.name}")
    ...
postgresql 08:10:14.72 INFO  ==> ** Starting PostgreSQL **
2022-02-01 08:10:14.734 GMT [1] FATAL:  database files are incompatible with server
2022-02-01 08:10:14.734 GMT [1] DETAIL:  The data directory was initialized by PostgreSQL version 11, which is not compatible with this version 14.1.
```

### To 10.0.0

[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.

- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
- Move dependency information from the _requirements.yaml_ to the _Chart.yaml_
- After running _helm dependency update_, a _Chart.lock_ file is generated containing the same structure used in the previous _requirements.lock_
- The different fields present in the _Chart.yaml_ file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Chart.
- The term _master_ has been replaced with _primary_ and _slave_ with _readReplicas_ throughout the chart. Role names have changed from _master_ and _slave_ to _primary_ and _read_.

#### Considerations when upgrading to this version

- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version does not support Helm v2 anymore.
- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3.

### To 9.0.0

In this version the chart was adapted to follow the [Helm standard labels](https://helm.sh/docs/chart_best_practices/labels/#standard-labels).

- Some inmutable objects were modified to adopt Helm standard labels introducing backward incompatibilities.
