FWIW, Deis really wants to help orchestrate multiple containers across nodes. There's talk about scheduling/pinning apps to certain nodes (such as if you really need your workers on a machine with more CPU), and currently we also support deploying from both Dockerfiles and pulling images bit-for-bit from an in-house registry or from DockerHub. We have documentation, but ASCIIcasts seem to show this workflow better. Check it out! http://deis.io/demo-deis-pull-in-action/
