Easiest way would be to deploy from a local registry. You can pull
everything from docker hub and just use kolla-build to build and push the
ones you're working on.

Then just delete the image from wherever it's running, run a deploy with
--tags of the project you're messing with, and it'll deploy the new image,
or increment the docker tag when you push it and run upgrade.

If I'm missing something and oversimplifying, let me know :).
