I cannot find a way to change the hostname of an existing container, neither with docker start, the API, or running “hostname XXX” in a startup script. Actaully would also be nice to change enviroment variables in existing containers and not just when creating.

I found a very simple way of achieving this. Install kitematic. This tools allows you to change the hostname - it will restart - after restarting it will be the newly applied hostname.
