**Please create:**
1. **Dockerfile:** Multi-stage build with optimized image size
   - Use official base images
   - Implement layer caching strategies
   - Use a non-root user
   - Set meaningful health checks

2. **docker-compose.yml:** Complete Compose configuration
   - Service definitions with dependencies
   - Network configuration
   - Volume mounts for persistence
   - Environment variables with .env file

3. **.dockerignore:** Optimized ignore rules

4. **Security Notes:** Best practices for container security

Optimize for minimal image size and fast build times.
