Docker overlay cleanup

Apps & App Center
, , ,
#1

Hi,

how can I cleanup /var/lib/docker/overlay/? Can I use

docker system prune

safely?

#2

AFAIK docker system prune will also remove stopped containers. So you’ll have to be sure that you have not stopped any app container.
IMHO it’s safer to manually remove unused images (those with <none> tags) using docker rmi <IMAGE ID>.

I’ve removed the old images already. But there are still some old volumes:

This doesn’t help me
So how to fix that

Can i delete all these volumes?
