Ok, easy enough, I just put it in fstab to mount a different partition
on /var/lib/docker. Presto, now I don’t have to worry about a container
using up all the OS’s disk space.
I don't know what's wrong in your case, but in order to have docker
store its files elsewhere, I created this file:
/etc/docker/daemon.json
with this in it:
{
"data-root": "/mnt/Data/cache/docker"
}
I stopped the docker daemon and did:
mkdir /mnt/Data/cache/
mv /var/lib/docker /mnt/Data/cache/
as root. Then started the docker daemon again and it worked.
/etc/docker/daemon.json is useful for other settings as well, like
enabling BuildKit by default without having to specify it on the command
line every time. I use:
{
"data-root": "/mnt/Data/cache/docker",
"features": { "buildkit": true }
}
