I'm a backend software developer, and we use docker at work. On my work machine, if I:

Stop and delete all docker containers (even the stopped ones only visible with -a)
Delete all docker images (even the intermediate ones only visible with -a)
Delete all docker volumes

And my docker system df shows:

TYPE            TOTAL     ACTIVE    SIZE      RECLAIMABLE
Images          0         0         0B        0B
Containers      0         0         0B        0B
Local Volumes   0         0         0B        0B
Build Cache     0         0         0B        0B

My /var/lib/docker dir is still huge:

/var/lib/docker - 54.8GB
/var/lib/docker/volumes - 4.3GB
/var/lib/docker/overlay2 - 12.4GB
/var/lib/docker/1001.1001 - 38.1GB

Is this normal? Can I clean this up somehow? Running docker system prune --volumes --force didn't help.

What’s your operating system and file system? – Florian Wendelborn Oct 01 '22 at 01:52

Not sure why it matters, but I'm on PopOS 22.04, on ext4 – John Oct 02 '22 at 14:07
it matters because Docker picks a storage driver for your file system. For example, for BTRFS, there’s this bug: https://github.com/moby/moby/issues/27653 – Florian Wendelborn Oct 02 '22 at 14:56
@FlorianWendelborn interesting. I'm guessing a BTRFS issue wouldn't apply to me though. Any reason my setup might be using so much space? – John Oct 02 '22 at 16:15
I have no clue why, just wanted to point out that OS/FS is important here – Florian Wendelborn Oct 03 '22 at 03:58

Why is my /var/lib/docker dir huge?
