feat: add Docker support for all MCP servers

- Create individual Dockerfiles for each of the 7 MCP servers - Add docker-compose.yml for orchestrating all services - Create build-docker.sh script for easy container building - Add comprehensive Docker deployment documentation (DOCKER.md) - Update main README with Docker installation instructions - Add .env.example template for environment configuration - Configure each server with dedicated ports (3000-3006) - Implement security best practices (non-root user, minimal base image) - Add production deployment considerations and troubleshooting guide Each server can now be run individually or all together using Docker Compose, making deployment and scaling much easier for production environments. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

+# Docker Deployment Guide for Portainer MCP Servers
+
+This guide covers how to build and run the Portainer MCP servers using Docker containers.
+
+## Prerequisites
+
+- Docker Engine 20.10+
+- Docker Compose 2.0+
+- Portainer Business Edition instance
+- Valid Portainer API key
+
+## Quick Start
+
+1. **Clone the repository**
+   ```bash
+   git clone https://github.com/yourusername/portainer-mcp.git
+   cd portainer-mcp
+   ```
+
+2. **Create environment file**
+   ```bash
+   cp .env.example .env
+   # Edit .env with your Portainer credentials
+   ```
+
+3. **Build all containers**
+   ```bash
+   ./build-docker.sh all
+   ```
+
+4. **Start all services**
+   ```bash
+   docker-compose up -d
+   ```
+
+## Individual Container Management
+
+### Building Containers
+
+Build all containers:
+```bash
+./build-docker.sh all
+```
+
+Build specific container:
+```bash
+./build-docker.sh core
+./build-docker.sh docker
+./build-docker.sh kubernetes
+# etc...
+```
+
+### Running Containers
+
+Run all services:
+```bash
+docker-compose up -d
+```
+
+Run specific service:
+```bash
+docker-compose up -d portainer-core
+docker-compose up -d portainer-docker
+# etc...
+```
+
+View logs:
+```bash
+docker-compose logs -f portainer-core
+docker-compose logs -f portainer-docker
+# etc...
+```
+
+Stop services:
+```bash
+docker-compose down
+```
+
+## Container Details
+
+Each MCP server runs in its own container with the following configuration:
+
+| Service | Container Name | Port | Purpose |
+|---------|---------------|------|---------|
+| portainer-core | portainer-mcp-core | 3000 | User management, teams, RBAC |
+| portainer-environments | portainer-mcp-environments | 3001 | Environment management |
+| portainer-docker | portainer-mcp-docker | 3002 | Docker operations |
+| portainer-kubernetes | portainer-mcp-kubernetes | 3003 | Kubernetes management |
+| portainer-stacks | portainer-mcp-stacks | 3004 | Stack deployment |
+| portainer-edge | portainer-mcp-edge | 3005 | Edge computing |
+| portainer-gitops | portainer-mcp-gitops | 3006 | GitOps automation |
+
+## Environment Variables
+
+All containers share the same environment variables:
+
+```bash
+# Required
+PORTAINER_URL=https://your-portainer-instance.com
+PORTAINER_API_KEY=your-api-key-here
+
+# Optional
+PORTAINER_INSECURE=false  # Set to true for self-signed certificates
+HTTP_TIMEOUT=30
+MAX_RETRIES=3
+```
+
+## Docker Compose Configuration
+
+The `docker-compose.yml` file defines all services with:
+- Individual port mappings
+- Shared environment variables
+- Automatic restart policies
+- Isolated network for inter-container communication
+
+## Production Deployment
+
+For production environments, consider:
+
+1. **Use Docker Swarm or Kubernetes**
+   ```bash
+   # Deploy as stack in Swarm
+   docker stack deploy -c docker-compose.yml portainer-mcp
+   ```
+
+2. **Enable health checks**
+   Add to each service in docker-compose.yml:
+   ```yaml
+   healthcheck:
+     test: ["CMD", "curl", "-f", "http://localhost:3000/health"]
+     interval: 30s
+     timeout: 10s
+     retries: 3
+   ```
+
+3. **Use secrets for API keys**
+   ```yaml
+   secrets:
+     portainer_api_key:
+       external: true
+   ```
+
+4. **Configure resource limits**
+   ```yaml
+   deploy:
+     resources:
+       limits:
+         cpus: '0.5'
+         memory: 256M
+   ```
+
+## Troubleshooting
+
+### Container won't start
+- Check logs: `docker-compose logs portainer-<service>`
+- Verify environment variables in `.env`
+- Ensure Portainer URL is accessible from container
+
+### Connection errors
+- For self-signed certificates, set `PORTAINER_INSECURE=true`
+- Check network connectivity: `docker exec portainer-mcp-core curl https://your-portainer-url`
+
+### Permission errors
+- Verify API key has required permissions
+- Check Portainer RBAC settings
+
+## Security Considerations
+
+1. **Never commit `.env` file** - It contains sensitive credentials
+2. **Use read-only mounts** where possible
+3. **Run containers as non-root user** (already configured)
+4. **Enable TLS** for MCP connections in production
+5. **Regularly update** base images and dependencies
+
+## Advanced Configuration
+
+### Custom Network
+```yaml
+networks:
+  portainer-mcp:
+    driver: bridge
+    ipam:
+      config:
+        - subnet: 172.20.0.0/16
+```
+
+### Volume Mounts
+For persistent logs or configuration:
+```yaml
+volumes:
+  - ./logs:/app/logs
+  - ./config:/app/config:ro
+```
+
+### Multi-stage Builds
+The Dockerfiles use single-stage builds for simplicity. For smaller images:
+```dockerfile
+FROM python:3.11-slim AS builder
+# Build stage...
+
+FROM python:3.11-slim
+# Runtime stage...
+```
+
+## Integration with Claude Desktop
+
+When running in Docker, configure Claude Desktop to connect to the containerized servers:
+
+```json
+{
+  "mcpServers": {
+    "portainer-core": {
+      "url": "http://localhost:3000"
+    },
+    "portainer-docker": {
+      "url": "http://localhost:3002"
+    }
+    // ... other servers
+  }
+}
+```
+
+## Monitoring
+
+Monitor container health and resource usage:
+```bash
+# View resource usage
+docker stats
+
+# Check container health
+docker ps --format "table {{.Names}}\t{{.Status}}"
+
+# Export metrics
+docker-compose ps --format json
+```
