Checkmate! The server has rebooted and all the containers are DOWN.

Its easy to make the containers reboot automatically. Use a RestartPolicy

  • Edit the restart policy for an already running container
    $ docker update --restart=always container01
    container01
    
  • Check the changes
    $ docker inspect container01 | grep RestartPolicy -A 3
              "RestartPolicy": {
                  "Name": "always",
                  "MaximumRetryCount": 0
              },
    

Your containers should now reboot automatically - but check the different policies, to see which one applies best to your case.
