# ESXi MCP Server - Docker Guide
|
||||||
|
|
||||||
|
This guide provides instructions for running the ESXi MCP Server using Docker and Docker Compose.
|
||||||
|
|
||||||
|
## Quick Start
|
||||||
|
|
||||||
|
### Prerequisites
|
||||||
|
|
||||||
|
- Docker 20.10+
|
||||||
|
- Docker Compose 2.0+
|
||||||
|
- Access to a VMware vCenter Server or ESXi host
|
||||||
|
|
||||||
|
### 1. Setup
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Clone the repository
|
||||||
|
git clone <repository-url>
|
||||||
|
cd esxi-mcp-server
|
||||||
|
|
||||||
|
# Create necessary directories and configuration
|
||||||
|
make setup
|
||||||
|
|
||||||
|
# Create environment variables file (optional)
|
||||||
|
make env-example
|
||||||
|
cp .env.example .env
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Configuration
|
||||||
|
|
||||||
|
You have two options for configuration:
|
||||||
|
|
||||||
|
#### Option A: Configuration File (Recommended)
|
||||||
|
|
||||||
|
Edit `config/config.yaml`:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
vcenter_host: "your-vcenter-ip"
|
||||||
|
vcenter_user: "administrator@vsphere.local"
|
||||||
|
vcenter_password: "your-password"
|
||||||
|
datacenter: "your-datacenter"
|
||||||
|
cluster: "your-cluster"
|
||||||
|
datastore: "your-datastore"
|
||||||
|
network: "VM Network"
|
||||||
|
insecure: true
|
||||||
|
api_key: "your-api-key"
|
||||||
|
log_level: "INFO"
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Option B: Environment Variables
|
||||||
|
|
||||||
|
Edit `.env` file:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
VCENTER_HOST=your-vcenter-ip
|
||||||
|
VCENTER_USER=administrator@vsphere.local
|
||||||
|
VCENTER_PASSWORD=your-password
|
||||||
|
VCENTER_DATACENTER=your-datacenter
|
||||||
|
VCENTER_CLUSTER=your-cluster
|
||||||
|
VCENTER_DATASTORE=your-datastore
|
||||||
|
VCENTER_NETWORK=VM Network
|
||||||
|
VCENTER_INSECURE=true
|
||||||
|
MCP_API_KEY=your-api-key
|
||||||
|
MCP_LOG_LEVEL=INFO
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Run the Server
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Build and run
|
||||||
|
make dev
|
||||||
|
|
||||||
|
# Or run in background
|
||||||
|
make run
|
||||||
|
|
||||||
|
# Check status
|
||||||
|
make status
|
||||||
|
|
||||||
|
# View logs
|
||||||
|
make logs
|
||||||
|
```
|
||||||
|
|
||||||

|
## Docker Architecture
|
||||||
|
|
||||||
|
### Multi-stage Build
|
||||||
|
|
||||||
|
The Dockerfile uses a multi-stage build process:
|
||||||
|
|
||||||
|
1. **Builder Stage**: Installs build dependencies and Python packages
|
||||||
|
2. **Production Stage**: Creates a minimal runtime image
|
||||||
|
|
||||||
|
### Security Features
|
||||||
|
|
||||||
|
- Runs as non-root user (`mcpuser`)
|
||||||
|
- Minimal base image (python:3.11-slim)
|
||||||
|
- Only necessary runtime dependencies
|
||||||
|
- Configurable resource limits
|
||||||
|
|
||||||
|
### Directory Structure
|
||||||
|
|
||||||
|
```
|
||||||
|
/app/
|
||||||
|
├── server.py # Main application
|
||||||
|
├── config.yaml.sample # Configuration template
|
||||||
|
├── docker-entrypoint.sh # Startup script
|
||||||
|
├── config/ # Configuration directory (mounted)
|
||||||
|
│ └── config.yaml # Runtime configuration
|
||||||
|
└── logs/ # Log directory (mounted)
|
||||||
|
└── vmware_mcp.log # Application logs
|
||||||
|
```
|
||||||
|
|
||||||
|
## Configuration Options
|
||||||
|
|
||||||
|
### Volume Mounts
|
||||||
|
|
||||||
|
- `./config.yaml:/app/config/config.yaml:ro` - Configuration file (read-only)
|
||||||
|
- `./logs:/app/logs` - Log directory
|
||||||
|
|
||||||
|
### Environment Variables
|
||||||
|
|
||||||
|
All configuration options can be set via environment variables:
|
||||||
|
|
||||||
|
| Variable | Description | Default |
|
||||||
|
|----------|-------------|---------|
|
||||||
|
| `VCENTER_HOST` | vCenter/ESXi hostname | Required |
|
||||||
|
| `VCENTER_USER` | Username | Required |
|
||||||
|
| `VCENTER_PASSWORD` | Password | Required |
|
||||||
|
| `VCENTER_DATACENTER` | Datacenter name | Auto-detect |
|
||||||
|
| `VCENTER_CLUSTER` | Cluster name | Auto-detect |
|
||||||
|
| `VCENTER_DATASTORE` | Datastore name | Auto-detect |
|
||||||
|
| `VCENTER_NETWORK` | Network name | VM Network |
|
||||||
|
| `VCENTER_INSECURE` | Skip SSL verification | true |
|
||||||
|
| `MCP_API_KEY` | API authentication key | None |
|
||||||
|
| `MCP_LOG_LEVEL` | Log level | INFO |
|
||||||
|
|
||||||
|
### Resource Limits
|
||||||
|
|
||||||
|
Default resource limits in docker-compose.yml:
|
||||||
|
|
||||||
|
- **Memory**: 512MB limit, 256MB reserved
|
||||||
|
- **CPU**: 0.5 cores limit, 0.25 cores reserved
|
||||||
|
|
||||||
|
## Health Checks
|
||||||
|
|
||||||
|
The container includes automatic health checks:
|
||||||
|
|
||||||
|
- **Interval**: 30 seconds
|
||||||
|
- **Timeout**: 10 seconds
|
||||||
|
- **Retries**: 3
|
||||||
|
- **Start Period**: 40 seconds
|
||||||
|
|
||||||
|
Check health manually:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
make health
|
||||||
|
```
|
||||||
|
|
||||||
|
## Networking
|
||||||
|
|
||||||
|
The server exposes:
|
||||||
|
|
||||||
|
- **Port 8080**: HTTP API endpoint
|
||||||
|
- **Path `/sse`**: Server-Sent Events endpoint
|
||||||
|
- **Path `/sse/messages`**: JSON-RPC messages endpoint
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Check Logs
|
||||||
|
|
||||||
|
```bash
|
||||||
|
make logs
|
||||||
|
```
|
||||||
|
|
||||||
|
### Check Container Status
|
||||||
|
|
||||||
|
```bash
|
||||||
|
make status
|
||||||
|
```
|
||||||
|
|
||||||
|
### Open Shell in Container
|
||||||
|
|
||||||
|
```bash
|
||||||
|
make shell
|
||||||
|
```
|
||||||
|
|
||||||
|
### Common Issues
|
||||||
|
|
||||||
|
1. **Configuration not found**: Ensure `config/config.yaml` exists or environment variables are set
|
||||||
|
2. **Permission denied**: Check that the `logs` directory is writable
|
||||||
|
3. **Connection failed**: Verify vCenter/ESXi connectivity and credentials
|
||||||
|
4. **Health check failed**: Check if the server is responding on port 8080
|
||||||
|
|
||||||
|
### Debug Mode
|
||||||
|
|
||||||
|
Run with debug logging:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Set in .env file
|
||||||
|
MCP_LOG_LEVEL=DEBUG
|
||||||
|
|
||||||
|
# Or in config.yaml
|
||||||
|
log_level: "DEBUG"
|
||||||
|
```
|
||||||
|
|
||||||
|
## Production Deployment
|
||||||
|
|
||||||
|
### Security Recommendations
|
||||||
|
|
||||||
|
1. Use a dedicated user account for vCenter access
|
||||||
|
2. Enable API key authentication
|
||||||
|
3. Use valid SSL certificates (set `insecure: false`)
|
||||||
|
4. Limit container resources
|
||||||
|
5. Use Docker secrets for sensitive data
|
||||||
|
|
||||||
|
### High Availability
|
||||||
|
|
||||||
|
For production deployments, consider:
|
||||||
|
|
||||||
|
- Running multiple container instances
|
||||||
|
- Using a load balancer
|
||||||
|
- Implementing persistent storage for logs
|
||||||
|
- Setting up monitoring and alerting
|
||||||
|
|
||||||
|
## Examples
|
||||||
|
|
||||||
|
### Basic Usage
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Start the server
|
||||||
|
make run
|
||||||
|
|
||||||
|
# Check if it's working
|
||||||
|
curl http://localhost:8080/sse
|
||||||
|
```
|
||||||
|
|
||||||
|
### API Authentication
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# With API key
|
||||||
|
curl -H "Authorization: Bearer your-api-key" http://localhost:8080/sse
|
||||||
|
```
|
||||||
|
|
||||||
|
### Development
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Development workflow
|
||||||
|
make build
|
||||||
|
make dev
|
||||||
|
|
||||||
|
# Make changes to code
|
||||||
|
# Rebuild and restart
|
||||||
|
make update
|
||||||
|
```
