I would think the docker only needs the overlays in the docker ps -a listing:

I wonder why so many overlays have been created over time and I hope I do not need all of them. May I purge the majority of these files? What is the best procedure for deleting them? May I just delete them all and then use a docker-compose up -d in the /etc/egroupware-docker directory?
