Just in case - I'm always amazed how many Docker users don't know about the prune command for cleaning up the caches and deleting unused container images and just slowly let their docker image cache eat their disk.
Prune is nice, but if you have a bunch of containers which run shirt time for a build step or similar prune would collect those, too. A filter "last used a few months ago" would be useful.
