PuppetCamp 2010

I’m off to PuppetCamp this week, October 7th and 8th at the City Club of San Francisco. Hopefully there will be some interesting conversations with others in charge of non-trivial, multi-site, multi-environment puppet systems.  At PowerReviews, we rely heavily upon puppet for automation and I’m hoping to pick up a few new tricks.

We just went through a big upgrade to version 2.5.5 and we are already looking at 2.6.1. The REST interface is pretty exciting and the stored configs are already simplifying the configuration of the distributed applications that need to know about the other hosts at their layer within the stack. Stored configs have almost automated our Nagios configuration.  We are getting close!  In earlier versions of puppet, global variables were used to hack a config together and I’m glad to see that they will be going away.

I have spent a fair amount of time working on cloud configurations lately and comparing the cloud offerings from AWS and Rackspace. Using puppet with a cloud platform seems to be bleeding edge at the moment. There are certainly blog posts that go back 18 months but they are a bit trivial and seem to be more proof of concept instead of examples of architecture at scale. I’m hoping to find others with real world puppet in the cloud experience. How do other shops set this up? There seem to be several ways of doing it – each with their associated pitfalls…
