Have you looked at docker-test.sh ?

https://github.com/ceph/ceph/blob/master/src/test/docker-test.sh

I have not tried it in awhile, but it used to be able to not only build 
Ceph but also run "make check", in a Docker container. It support(ed) 
several different operating systems.

It would be nice if someone got it working again.
