    # the :cached is optional, but we hope it improves inotify events.

    # this is needed for automatic discovery of mounted volumes in this container.

    volumes_from:
    - moodle
    # Privilegied mode is needed if you want to increase the maximum inotify watches for very large synced folders
    # by setting the ENV var MAXIMUM_INOTIFY_WATCHES.
    #privileged: true
volumes:
  mariadb_data:
    driver: local
  moodle_data:
    driver: local
  moodledata_data:
    driver: local
  phpu_moodledata_data:
    driver: local

I would like to sync the moodle_data to host folder. I always get error:
