# Backend API service example, uses nodemon to keep server alive and watch for changes.
backendapi:
  # Tells docker-compose where ./backendapi/Dockerfile is
  build: ./backendapi
  # Allows live editing of ./backendapi/app
  volumes:
    - ./backendapi/app:/app
  # Launch Nodemon, using 
  # -L legacy file watching for compatibility with boot2docker / docker-machine. 
  # --watch defined to avoid watching the whole container and causing high CPU usage
