--remove-volumes doesn't work as expected with named volumes

[leninalive]

When using named volumes with docker-compose and watchtower, it won't remove named volumes with --remove-volumes argument (will only deassociate them from container) though volume contents won't be updated.

Is it possible to change this behavior and perform something like docker volume prune after container has been stopped and removed?

Hey there!

You should be able to do this already using lifecycle hooks. For instance, you could add a script running docker volume prune on post-update. Another solution, which I tend to utilize myself, is to add a cronjob running the prune command every night.
