Relevant link: moby/moby#33930 :
A new obsoletes restriction was introduced in docker-ce 17.06.0 and it looks like the yum repo is applying it to all versions of the docker-ce indiscriminately. To work around this when installing older versions of docker-ce, you can pass a flag to ignore obsoletes: --setopt=obsoletes=0
