💾 Volume Management

When running with Docker or Docker Compose, data is persisted using a volume:

volumes:
  data:
    name: simpletool-server-data    
    driver_opts:
      type: none
      o: bind
      device: ${PWD}/data

This maps to /app/server/data in the container and stores:

  • 📋 User configurations
  • 🔧 Tool configurations
  • 🔐 Authentication data

​
🚀 Example Configurations
