Comment (by dustin):

 So this dockerfile logs to stdout, making the logs visible with `docker
 logs`.  Something similar should work for the slave.  This also runs
 Buildbot as non-root (!).

 {{{
 # Launch with: docker run -d -p 8010:8010 -p 9989:9989 --name="bb-master"
 buildbot-master
 FROM ubuntu:precise

 # Install base dependencies
 RUN apt-get -q update && apt-get -y -q install python-dev git python-pip
 sudo vim

 # Install Buildbot Master
 RUN pip install sqlalchemy==0.7.10 buildbot

 # Create a Master
 RUN buildbot create-master master
 RUN mv master/master.cfg.sample master/master.cfg
 RUN chown -R daemon /master

 # comment out the custom logging in buildbot.tac
 RUN sed -i -e 's!application.setComponent!#application.setComponent!'
 /master/buildbot.tac

 EXPOSE 9989 8010

 # Start Buildbot Master
 USER daemon
 CMD twistd --no_save -n --logfile=- --python=master/buildbot.tac
 --pidfile=master/twistd.pid
 }}}

 However, port 8010 doesn't seem to be open for me.  If I connect to it, it
 closes right away.  I'm not really sure how to debug that!
