Carbonio CE - Docker version Ubuntu 20.4

Doing a search on Docker Hub I found several images, but none with instructions or documentation.
Does anyone have any information that can help me with the installation?
I already tried to run the image, but I couldn't access it.

This is actually working as a rudimentary base.

now i just have to figure out how to get the files stuff running, once this is ok i might consider switching from kopano to carbonio

@emstersj what did you have in container.config? where did it originate? For all I can see the single-server setup is incomplete since it doesn't run a configuration and thus fails to properly setup ldap. The multi-server has this setup script pointing at the container.config file, which I don't see anywhere. I suspect it's part of some package i'm not installing (yet)

I'm at a loss, the only thing I could find beyond this is in ./store/spec/helper/container.sh
