# Docker Setup

This guide covers deploying MCPHub using Docker, including development and production configurations.

## Quick Start with Docker

### Using Pre-built Image

```bash
# Pull the latest image
docker pull mcphub/mcphub:latest

# Run with default configuration
docker run -d \
  --name mcphub \
  -p 3000:3000 \
  -v $(pwd)/mcp_settings.json:/app/mcp_settings.json \
  mcphub/mcphub:latest
```

### Building from Source

```bash
# Clone the repository
git clone https://github.com/your-username/mcphub.git
cd mcphub

# Build the Docker image
docker build -t mcphub:local .

# Run the container
docker run -d \
  --name mcphub \
  -p 3000:3000 \
  -v $(pwd)/mcp_settings.json:/app/mcp_settings.json \
  mcphub:local
```

### Building with Extended Features

The Docker image supports an `INSTALL_EXT` build argument to include additional tools:

```bash
# Build with extended features (includes Docker Engine, Chrome/Playwright)
docker build --build-arg INSTALL_EXT=true -t mcphub:extended .

# Option 1: Run with automatic Docker-in-Docker (requires privileged mode)
docker run -d \
  --name mcphub \
  --privileged \
  -p 3000:3000 \
  -v $(pwd)/mcp_settings.json:/app/mcp_settings.json \
  mcphub:extended

# Option 2: Run with Docker socket mounted (use host's Docker daemon)
docker run -d \
  --name mcphub \
  -p 3000:3000 \
  -v $(pwd)/mcp_settings.json:/app/mcp_settings.json \
  -v /var/run/docker.sock:/var/run/docker.sock \
  mcphub:extended

# Verify Docker is available
docker exec mcphub docker --version
docker exec mcphub docker ps
```

<Note>
  **What's included with INSTALL_EXT=true:**
  - **Docker Engine**: Full Docker daemon with CLI for container management. The daemon auto-starts when the container runs in privileged mode.
  - **Chrome/Playwright** (amd64 only): For browser automation tasks
  
  The extended image is larger but provides additional capabilities for advanced use cases.
</Note>

<Warning>
  **Docker-in-Docker Security Considerations:**
  - **Privileged mode** (`--privileged`): Required for the Docker daemon to start inside the container. This gives the container elevated permissions on the host.
  - **Docker socket mounting** (`/var/run/docker.sock`): Gives the container access to the host's Docker daemon. Both approaches should only be used in trusted environments.
  - For production, consider using Docker socket mounting instead of privileged mode for better security.
</Warning>

## Docker Compose Setup

### Basic Configuration

Create a `docker-compose.yml` file:

```yaml
version: '3.8'

services:
  mcphub:
    image: mcphub/mcphub:latest
    # For local development, use:
    # build: .
    container_name: mcphub
    ports:
      - '3000:3000'
    environment:
      - NODE_ENV=production
      - PORT=3000
      - JWT_SECRET=${JWT_SECRET:-your-jwt-secret}
      - DB_URL=postgresql://mcphub:password@postgres:5432/mcphub
    volumes:
      - ./mcp_settings.json:/app/mcp_settings.json:ro
      - ./servers.json:/app/servers.json:ro
      - mcphub_data:/app/data
    depends_on:
      postgres:

  redis_data:
  mcphub_data:
  mcphub_logs:
  nginx_logs:

networks:
  mcphub-network:
    driver: bridge
```

### Environment Variables

Create a `.env` file for Docker Compose:

```env
# Application
NODE_ENV=production
JWT_SECRET=your-super-secret-jwt-key-change-this
JWT_EXPIRES_IN=24h

# Database
POSTGRES_PASSWORD=your-secure-database-password

# Redis
REDIS_PASSWORD=your-secure-redis-password

# External APIs
OPENAI_API_KEY=your-openai-api-key

# Optional: Custom port
# PORT=3000
```

## Development Setup

### Development Docker Compose

Create `docker-compose.dev.yml`:

```yaml
version: '3.8'

services:
  mcphub-dev:
    build:
      context: .
      dockerfile: Dockerfile.dev
    container_name: mcphub-dev
    ports:
      - '3000:3000'
      - '5173:5173' # Frontend dev server
      - '9229:9229' # Debug port
    environment:
      - NODE_ENV=development
      - PORT=3000
      - DB_URL=postgresql://mcphub:password@postgres:5432/mcphub
    volumes:
      - .:/app
      - /app/node_modules
      - /app/frontend/node_modules
    depends_on:
      - postgres
    command: pnpm dev
    networks:
      - mcphub-dev

  postgres:
    image: pgvector/pgvector:pg17
    container_name: mcphub-postgres-dev
    environment:
      - POSTGRES_DB=mcphub
      - POSTGRES_USER=mcphub
      - POSTGRES_PASSWORD=password
    ports:
      - '5432:5432'
    volumes:
      - postgres_dev_data:/var/lib/postgresql/data
    networks:
      - mcphub-dev

volumes:
  postgres_dev_data:

networks:
  mcphub-dev:
    driver: bridge
```

### Development Dockerfile

Create `Dockerfile.dev`:

```dockerfile
FROM node:20-alpine

# Install pnpm
RUN npm install -g pnpm

# Set working directory
WORKDIR /app

# Copy package files
COPY package.json pnpm-lock.yaml ./
COPY frontend/package.json ./frontend/

# Install dependencies
RUN pnpm install

# Copy source code
COPY . .

# Expose ports
EXPOSE 3000 5173 9229

# Start development server
CMD ["pnpm", "dev"]
```

## Running the Application

### Development Mode

```bash
# Start development environment
docker-compose -f docker-compose.dev.yml up -d

# View logs
docker-compose -f docker-compose.dev.yml logs -f mcphub-dev

# Stop development environment
docker-compose -f docker-compose.dev.yml down
```

### Production Mode

```bash
# Start production environment
docker-compose up -d

# View logs
docker-compose logs -f mcphub

# Stop production environment
docker-compose down
```

## Configuration Management

### MCP Settings Volume Mount

Create your `mcp_settings.json`:

```json
{
  "mcpServers": {
    "fetch": {
      "command": "uvx",
      "args": ["mcp-server-fetch"]
    },
    "playwright": {
      "command": "npx",
      "args": ["@playwright/mcp@latest", "--headless"]
    },
    "amap": {
      "command": "npx",
      "args": ["-y", "@amap/amap-maps-mcp-server"],
      "env": {
        "AMAP_MAPS_API_KEY": "your-api-key"
      }
    }
  }
}
```

### Secrets Management

For production, use Docker secrets:

```yaml
version: '3.8'

services:
  mcphub:
    image: mcphub/mcphub:latest
    environment:
      - JWT_SECRET_FILE=/run/secrets/jwt_secret
      - DATABASE_PASSWORD_FILE=/run/secrets/db_password
    secrets:
      - jwt_secret
      - db_password

secrets:
  jwt_secret:
    file: ./secrets/jwt_secret.txt
  db_password:
    file: ./secrets/db_password.txt
```

## Data Persistence

### Database Backups

Add backup service to your `docker-compose.yml`:

```yaml
services:
  backup:
    image: pgvector/pgvector:pg17
    container_name: mcphub-backup
    environment:
      - PGPASSWORD=${POSTGRES_PASSWORD}
    volumes:
      - ./backups:/backups
      - ./scripts/backup.sh:/backup.sh:ro
    command: /bin/sh -c "chmod +x /backup.sh && /backup.sh"
    depends_on:
      - postgres
    profiles:
      - backup
    networks:
      - mcphub-network
```

Create `scripts/backup.sh`:

```bash
#!/bin/sh
BACKUP_FILE="/backups/mcphub_$(date +%Y%m%d_%H%M%S).sql"
pg_dump -h postgres -U mcphub -d mcphub > "$BACKUP_FILE"
echo "Backup created: $BACKUP_FILE"

# Keep only last 7 days of backups
find /backups -name "mcphub_*.sql" -mtime +7 -delete
```

Run backup:

```bash
docker-compose --profile backup run --rm backup
```

## Monitoring and Health Checks

### Health Check Endpoint

Add to your application:

```javascript
// In your Express app
app.get('/health', (req, res) => {
  res.json({
    status: 'healthy',
    timestamp: new Date().toISOString(),
    uptime: process.uptime(),
    memory: process.memoryUsage(),
    version: process.env.npm_package_version,
  });
});
```

### Docker Health Checks

```yaml
services:
  mcphub:
    # ... other config
    healthcheck:
      test: ['CMD', 'wget', '--quiet', '--tries=1', '--spider', 'http://localhost:3000/health']
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 60s
```

### Monitoring with Watchtower

Add automatic updates:

```yaml
services:
  watchtower:
    image: containrrr/watchtower
    container_name: mcphub-watchtower
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - WATCHTOWER_CLEANUP=true
      - WATCHTOWER_POLL_INTERVAL=3600
      - WATCHTOWER_INCLUDE_STOPPED=true
    restart: unless-stopped
```

## Troubleshooting

### Common Issues

**Container fails to start**: Check logs with `docker-compose logs mcphub`

**Database connection errors**: Ensure PostgreSQL is healthy and accessible

**Port conflicts**: Check if ports 3000/5432 are already in use

**Volume mount issues**: Verify file paths and permissions

### Debug Commands

```bash
# Check container status
docker-compose ps

# View logs
docker-compose logs -f [service_name]

# Execute commands in container
docker-compose exec mcphub sh

# Check database connection
docker-compose exec postgres psql -U mcphub -d mcphub

# Restart specific service
docker-compose restart mcphub

# Rebuild and restart
docker-compose up --build -d
```

### Performance Optimization

```yaml
services:
  mcphub:
    # ... other config
    deploy:
      resources:
        limits:
          memory: 512M
          cpus: '0.5'
        reservations:
          memory: 256M
          cpus: '0.25'
```

This Docker setup provides a complete containerized environment for MCPHub with development and production configurations.
