It's our intent to support arbitrary docker images running on openshift. "No extra configuration" is a pretty absolute statement that I don't think we can promise, but we do intend to extract metadata from the docker image where possible and guide users through the deployment of such an image.

We'll have some first class images that we maintain+support for running on openshift, just like today. You can see the beginnings of that here:

That repository is the working repo for our v3 effort (equivalent to origin-server for v2), so it will evolve over time into the production release. However at the moment it should be considered to be very very alpha.

It does work on Fedora (fc20 at least), though I know there have been a few gotchas with go-lang packaging issues and possibly other things, so you'll have to elaborate on the issue you're hitting.
