Is the UI meant to run in the same container as Cruise Control? Would we for example switch to this build in https://github.com/Yolean/kubernetes-kafka/blob/master/cruise-control/50cruise-control.yml and open up a port?

Yes, in the same container, in the same process actually. Cruise Control can serve static content along with the REST endpoints. One of the supported configs for the UI is to add the files into the directory already configured to serve content. This PR does this.

I would like to switch 50cruise-control.yml to use the new image. The UI is served over the same port as the API. Port 8090 is already opened, so no additional work.

Great! The Cruise Control setup is a perfect example of a community effort. I still don't know anything about Cruse Control and we nevertheless have it up and running :) I'll build a new image and bump in a kubernetes-kafka branch that you can verify.
