Dear Harry,
`docker image prune -a` removes all dangling images as well as all
images not referenced by any running container. I successfully used it
in my setups to remove old versions.
In RHEL/CentOS, podman is used and thus you should use `podman image
prune -a` instead.
HTH, Cheers

Does ceph remove container subvolumes holding previous revisions of
daemon images after upgrades?
I have a couple servers using btrfs to hold the containers. The number
of docker related sub-volumes just keeps growing, way beyond the number
of daemons running. If I ignore this, I'll get disk-full related system
failures.
Is there a command to 'erase all non-live docker image subvolumes'? Or
a way to at least get a list of what I need to delete manually ( !! )
Thanks
Harry Coin
