I have a little problem. I have a brand new Red Hat Linux Server and I installed Docker CE for CentOS/Red Hat with the official repositories for Docker CE. Now I see that docker creates the container under /var/lib/docker, but my problem is that I use an extra partition for my data under /data/docker. How can I change the default root directory for Docker in CentOS/Red Hat?
I tried a few HOWTOs but I get the same problem. I can’t find the configuration. For example, I search for the following files:
/etc/default/docker(I think only for Debian/Ubuntu)/etc/systemd/system/docker.service.d/override.conf(I can't find on my system)/etc/docker/daemon.json(I can't find on my system)
If I get the docker info I see:
Docker Root Dir: /var/lib/docker
linux directory docker

Stop all running docker containers and then docker daemon. Move "/var/lib/docker" directory to the place where you want to have this data.
For you it would be:
mv -r /var/lib/docker /data/
and then create symlink for this docker directory in /var/lib path:
ln -s /data/docker /var/lib/
Start docker daemon and containers.

You'll also want to run:semanage fcontext -a -e /var/lib/docker /data/docker
