What is the explicit behaviour of 'docker restart'?

The docker docs just say this command will "restart one or more containers". But that isn't clear enough for me.

Is this effectively;

if (container.isRunning) {
   docker stop container
   docker start container
} else {
   docker start container
}

?

ie. if the container isn't running, it will be docker start'ed, and if it is it will be stopped and then started again?

Effectively, yes, with some additional considerations to care for interactions between different features such as to avoid deleting a container started with AutoRemove --rm (normally they are autoremoved on stop but should not be on restart)

See the implementation here: https://github.com/moby/moby/blob/de7172b600d5fbdf6d8861116bf5491d17d609be/daemon/restart.go#L37
