Your system (I assume that this is a Linux OS) should start the docker engine automatically (you can check it is running via
The docker engine, in turn, will restart a running container (except if you use specific
--restart flags, but the one you mentioned is fine).
So you can start the container once for all via your command (though you should map a volume so that your information is persistent, otherwise once you upgrade you will lose everything you configured and your passwords - this is the normal behaviour of docker, BW has nothing to do with that).
I would suggest you use
docker-compose to manage your containers, it is much easier as you go on.
