[k8s] Configuration files as ConfigMap?

[moritzj29]

Hi, I'm pretty new to seafile and I'm looking for an easy way to manage my seafile configuration. I deployed seafile using the k8s templates from this respository (Thanks a lot!).
If I now need to modify some of the configuration, e.g. seahub_conf.py, I need to get a shell in the running container and edit the configuration file, which feels quite not quite right for containers...
I understand that seahub_conf.py is generated automatically upon first deployment. But after that is it still modified by seafile/seahub itself, e.g. during an update?
If it is not modified at all, I would try to mount the configuration as a ConfigMap which is read-only in the container. But it would be very handy to change configuration parameters and track the changes in git.
(Setting all configuration values via environment variables is not supported, right?)
