Generate Docker Compose Configuration Files

```yaml version: '3.8' services: # PostgreSQL Database postgres: image: postgres:15-alpine environment: POSTGRES_DB: myapp POSTGRES_USER: ${DB_USER:-postgres} POSTGRES_PASSWORD: ${DB_PASSWORD:-password} volumes: - postgres_data:/var/lib/postgresql/data - ./init.sql:/docker-entrypoint-initdb.d/init.sql ports: - "5432:5432" restart: unless-stopped healthcheck: test: ["CMD-SHELL", "pg_isready -U ${DB_USER:-postgres}"] interval: 30s timeout: 10s retries: 3 # Redis Cache redis: image: redis:7-alpine ports: - "6379:6379" restart: unless-stopped healthcheck: test: ["CMD", "redis-cli", "ping"] interval: 30s timeout: 10s retries: 3 # Node.js API Server api: build: context: ./backend dockerfile: Dockerfile environment: - NODE_ENV=development - DATABASE_URL=postgresql://${DB_USER:-postgres}:${DB_PASSWORD:-password}@postgres:5432/myapp - REDIS_URL=redis://redis:6379 ports: - "3000:3000" depends_on: postgres: condition: service_healthy redis: condition: service_healthy restart: unless-stopped volumes: - ./backend:/app - /app/node_modules volumes: postgres_data: networks: default: driver: bridge ``` **Usage Guide:** 1. Create a `.env` file with your environment variables 2. Run `docker-compose up -d` to start all services 3. Use `docker-compose logs -f` to monitor logs 4. Stop with `docker-compose down`
