as part of an intro tutorial i'm writing, i want to provide a recipe for installing docker-ce on fedora 29 from absolute scratch, and part of that will involve how to first get rid of every trace of any old docker- or container-related stuff.
if one has no interest in preserving old containers, i'm proposing running (as sudo, naturally):
$ dnf remove "*docker*" $ rm -rf /var/lib/{containerd,docker,docker-engine}
i'm fairly sure that's overkill, but the point is to simulate truly starting from scratch. the above *seems* to work, is there any reason it would cause problems before i kick in with installing the proper yum repo file and running:
$ dnf install docker-ce
thoughts?

After running your "dnf remove" and "rm -rf" commands run "# locate docker". There may be config files left behind or other cruft in home dirs.

Before running "locate" you should run "updatedb".

If the computer has LVM partions it is probably worth checking that the docker-pool thin pool has been deleted, as docker can use this if there is space in LVM, and I don't know if uninstalling docker is enough to remove it.

atomic storage reset
I believe does the right thing. It should cleanup devicemapper as well.
BTW Could you article also explain how to use podman in place of docker on Fedora 29.
You could expand it to, how to convert an installed docker to a podman configuration.
Something like
for image in $(docker image -q); do
podman pull image docker-daemon:$image
dockre rmi --force $image
done
atomic storage reset
rpm -e docker*
dnf install podman-docker

just checking on this ... the "atomic" command is part of the "atomic" package, which is not technically required to run docker on my fedora 29 system, so it's currently not installed.
are you saying that that package would be applicable in my current situation?

If you are using overlay, then you can simply rm -rf /var/lib/docker.
If you are using devicemapper, then you should either use atomic storage reset, or look what it is doing and then implement your own script to cleanup the devices.
