Answer

  • always: restart the container when it's stopped (not with docker container stop)
    • unless-stopped: restart the container unless it was in stopped status
    • no: don't restart the container at any point (default policy)
    • on-failure: restart the container when it exists due to an error (= exit code different than zero)
