Nice!
I've never seen the use of FROM twice in the same Dockerfile.
I see this is new in https://docs.docker.com/v17.09/engine/userguide/eng-image/multistage-build/#use-multi-stage-builds. Perhaps we should add comment specifying you'd need a 17.09 or later?
Unrelated, the existing Dockerfile is about to get a facelift. It is plain wrong: it pulls orchestrator from origin/master as opposed to running the very branch you're on. TODO.
