Running out of space in /var directory due to docker images

docker images are stored under /var/lib/docker

If you run out of space in /var partition.?

ok move /var/lib/docker directory to /root (considering space is available under /root) and create a symlink from /var/lib/docker to /root/docker.

Ensure you stop docker service before moving and verify docker daemon works fine after creating symlink.

so, all the commands put together:

systemctl stop docker

mv /var/lib/docker /root/

ln -sf  /root/docker /var/lib/docker

systemctl start docker

systemctl status  docker

thats it :)
