It seems we can benefit already from using Docker. For instance, if I can bring up my entire stack with one command, it will make it far easier for everyone to follow along. That gives benefits for demos, and for anyone on the internet to try out our code. Also, we can integrate this into our Travis builds and do a full stack test.
I have started this (see Github issue), and immediately run into a snag with a stack trace. I’m guessing some code is missing somewhere. No matter, we’ll fix that with a second Github issue.
