 ## 🚀 Features

- **Lightweight**: Based on Alpine Linux (~10-15MB image)
 - **Configurable**: Environment variable driven configuration
 - **Socket Management**: Automatic UNIX socket creation and cleanup
 - **Production Ready**: Includes proper error handling and logging
- **Multi-variant**: Standard and minimal Docker images available
