# BazBeans - Generic Multi-Node Control Plane Toolkit

> **Orchestrate distributed applications with ease** - A reusable toolkit for managing multi-node deployments with automatic health monitoring, load balancer integration, and centralized control.

## 🎯 What is BazBeans?

BazBeans is a **generic control plane toolkit** that helps you manage distributed applications across multiple servers. Think of it as the "operating system" for your cluster - it handles the hard parts of distributed coordination so you can focus on your application.

> **BETA** : This project is new. Use at your own risk. We're developing the framework and it's early days.  We're using it for our own project(s), but would not recommend using in production without testing and a fallback plan.  I mean... we are using it, but don't necessarily do as we do.  Or try it, you may love it.   :-)

> **macOS** : The project includes macOS support, but has not been tested.

### 🚀 Key Capabilities

- **🏥 Self-Healing Nodes** - Nodes monitor their own health and automatically remove themselves from the load balancer when unhealthy
- **🎛️ Centralized Control** - Manage your entire cluster from a simple command-line interface
- **⚡ Auto Load Balancing** - Automatic Nginx upstream updates via Redis pub/sub
- **🔌 Pluggable Architecture** - Add custom health checks, commands, and IP resolution strategies
- **🔄 Zero Project Coupling** - Generic design works with any application stack
- **🚀 One-Click CLI Installation** - Auto-installs OS-specific CLI when you `pip install bazbeans`

## 🛠️ Configuration Examples

### Basic Web Server Setup
```python
from bazbeans import BazBeansConfig, NodeAgent, DockerComposeCommands

config = BazBeansConfig(
    redis_url="redis://cluster-redis:6379/0",
    node_id="web-server-01",
    data_center="us-east-1",
    node_port=8000,
    cpu_threshold=85,
    memory_threshold=80
)

agent = NodeAgent(config)
agent.register_command_plugin(DockerComposeCommands(config))

# Add web-specific health check
@agent.health_check
def check_web_health():
    import requests
    return requests.get("http://localhost:8000/health").status_code == 200

agent.run()
```

### Database Server Setup
```python
config = BazBeansConfig(
    redis_url="redis://cluster-redis:6379/0",
    node_id="db-server-01",
    data_center="us-east-1",
    cpu_threshold=95,  # Higher threshold for databases
    memory_threshold=90
)

agent = NodeAgent(config)

# Add database-specific health checks
@agent.health_check
def check_database():
    # Your database connection logic
    return database.is_connected()

@agent.health_check
def check_replication():
    # Check replication lag
    return database.replication_lag() < 10

agent.run()
```

---

## 🎮 CLI Commands

### Node Management
```bash
# List all nodes with health status
bazbeans list-nodes

# Get detailed node information
bazbeans status web-server-01

# Freeze a node (remove from load balancer)
bazbeans freeze web-server-01 --reason "maintenance"

# Unfreeze a node
bazbeans unfreeze web-server-01
```

### Service Control
```bash
# Start services on a node
bazbeans start web-server-01

# Stop services
bazbeans stop web-server-01

# Restart services
bazbeans restart web-server-01

# Rolling update across datacenter
bazbeans update --dc us-east-1
```

### Operations
```bash
# Execute commands on nodes
bazbeans exec web-server-01 "docker ps"

# Deploy files to nodes
bazbeans deploy-file web-server-01 ./config.yaml /opt/app/config.yaml

# Clean up dead nodes
bazbeans cleanup
```

## 🔌 Extensibility

### Custom Health Checks
```python
@agent.health_check
def check_custom_service():
    """Check if your custom service is healthy."""
    try:
        # Your health check logic
        return service.ping()
    except:
        return False

@agent.health_check
def check_disk_space():
    """Custom disk space check."""
    import psutil
    return psutil.disk_usage('/app').percent < 95
```

### Custom Command Handlers
```python
@agent.command_handler("backup")
def handle_backup(command):
    """Handle backup commands."""
    # Your backup logic
    return {"status": "backup_started", "timestamp": time.time()}

@agent.command_handler("custom_action")
def handle_custom(command):
    """Handle custom business logic."""
    # Your custom logic
    return {"status": "completed", "result": "success"}
```

### IP Resolution Strategies
```python
from bazbeans.ip_resolvers import (
    RedisIPResolver,      # Nodes self-register IPs
    DNSIPResolver,        # DNS lookup
    StaticIPResolver,     # Static mapping
    ChainedIPResolver     # Primary + fallback
)

# Choose your strategy
resolver = ChainedIPResolver(
    primary=RedisIPResolver(redis_client),
    fallback=StaticIPResolver({"emergency-ip": "10.0.1.100"})
)
```

## 🔒 Security Considerations

### Redis Security
```bash
# Enable Redis authentication
requirepass your-secure-password

# Use TLS in production
tls-port 6380
tls-cert-file /path/to/redis.crt
tls-key-file /path/to/redis.key

# Network isolation
bind 10.0.1.10 127.0.0.1
```

### Agent Security
```python
# Run as non-root user
# Use virtual environments
# Validate file paths
# Whitelist allowed commands
config.allowed_exec_prefixes = ["docker", "systemctl", "ls"]
```

### Network Security
- Use VPN or private networks
- Implement firewall rules
- Monitor for unauthorized access
- Regular security audits
