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.

Nope, that’s just a limitation one has to live with. To change the hostname would has to rebuild the container.
