Anything else do we need to know:
This is directly related to this issue: moby/moby#33930

Apparently their obsoleting of docker-ce-selinux made the package obsolete for all versions in the repo. And currently there is no way of passing --setopt=obsoletes=0 to the ansible yum module.

I had the same problem and I had to disable the obsolete in yum.conf
