I have a $HOME/custom.yaml environment file which contains this:
If you do something similar and then include that environment in your
--environments list you should end up with just a single controller.
Do this in addition to using environments/puppet-pacemaker.yaml and you
should have "single node HA" (aka pacemaker on a single controller).
