Just up front: I'm one of the folks developing Empire.

That said, what we do is we have our CI system build our docker images, push them to dockerhub (private registry) if the tests all go great, and then we deploy using https://github.com/remind101/deploy. We also tag all our images with the git SHA that they were created from, so we have immutable identifiers for each image, which has been useful.

We just recently put direct github deployment support in Empire, so that's been really nice (before we had to use another service that pulled deployments and put them into Empire).

Anyway, not quite the workflow you're talking about, but it's really worked well for us, so maybe it'd help you as well :)
