Comment (by rutsky):

 3. What is the best practices of running Buildbot inside Docker?

    How master configuration should go inside master instance? How master
 configuration should be updated (e.g. `buildbot reconfig ...`)? Which part
 should be moved to volumes (builds history, artifacts)? How to do zero-
 downtime upgrade of master or it's configuration?
