5:46 a.m.
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.

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.
