So maybe writing modules isn’t something you want to hassle with. Ok, that’s cool. Puppetlabs has provided a place where you can leach off of others. In this article, I will talk about how to use PuppetForge (forge.puppetlabs.com)

There is a good chance that if you thought of a module to write, someone may have already done it and can save you a LOT of work. Most of the modules will support the big three Linux flavors out there, but not all so your results may vary with each and every module. Puppetlabs is working on improving that, but its something to keep in mind as we go through this article.

Time to wrap a bow on one of my goals for 2012. 5x5K is officially complete with the finish of The Color Run – Des Moines.

It was a bit chilly for the run but it was a blast. No times, just 27,000 of your friends running a 5K and getting colored power thrown on them. Quite the experience and I recommend it to just about everyone. Walkers, runners, kids. All are welcome!

We’re onto post 3 of our Puppet series. We have a master server, a client and we’ve made a connection. Its time to start getting into the real power of puppet and write our first module.

If you’re reading this, there is a good chance that you do some sort of project work within your job. My blog doesn’t attact a lot of people outside of IT and the typical IT guy is working on project X, Y or Z and sometimes all 3 at the same time. If this isn’t you, I’ll save you some time and you can stop reading now.

Ok, so you are working with your boss and he/she has assigned you a project. Maybe its mapped out with all of the details or if you are like me, you will typically get a broad project goal and its your job to come up with the milestones and timeline.

In our first post, we gave you the overview of what puppet was and how to install the software so its available on your system. Now its time to get into the guts of the system and get your client connecting to your master server.

Configuration

By default, puppet really wants to look for a server at puppet.. If you need to change this to a different server name, you’ll want to edit the /etc/puppet/puppet.conf file and add in an entry such as this:
