I currently have a Puppet Master and two agents, on the Puppet Master I am updating a json file and using that (via hiera) to get a list of running sites and deploy them to one of the agents.

  • As Greg mentioned, pssh to trigger the runs kicked off after an appropriate time later to avoid the race condition.
  • Mcollective might be a possibility in the near future if the Redis backend goes mainstream. Currently it's a fair amount of work to get the middleware required for Mcollective up and running on Debian based distros in my experience.

As explained in my post, I have done, it seems overkill however for this one call to a single machine.
