Seafile 12 as non-root container in openshift

I am currently trying to migrate the seafile binary setup to the docker based setup.
Our Openshift Setup does not allow to run commands as root inside a running pod/container. In fact, this is basic Openshift security. Its also not possible to change the security context.
This prevents the /scripts/enterpoint.sh commands to run properly because some commands have to run as root at startup.

Are there any hints I’ve missed in the admin manual, to get the dockerfile running in a restricted usercontext?
