You need to ensure that the base rhel container you use is able to run yum commands against a RHEL repository at docker build time. I think that if you use the standard rhel container plus run subscription-manager on your nodes, this should more or less "just" work (it may require some minimal change to the Dockerfile, I haven't tested this scenario). I don't use subscription-manager yet; the way I do things is to put a file /etc/yum.repos.d/redhat.repo (it must be this exact filename) on my nodes, which points to my own mirrored yum repository. /etc/yum.repos.d/redhat.repo on the node is automagically provided inside the container as /var/run/secrets/rhel7.repo by the RHEL docker tooling.

If you're aware of ways to make this bootstrapping easier (technical changes, documentation, whatever), please send PRs and I'll merge them.
