      {
        "Type": "volume",
        "Name": "ttt973993_airflow_logs",
        "Source": "/var/lib/docker/volumes/ttt973993_airflow_logs/_data",
        "Destination": "/usr/local/airflow/logs",
        "Driver": "local",
        "Mode": "z",
        "RW": true,
        "Propagation": ""
      }
