Infrastructures are growing rapidly and becoming more complex. Wouldn’t it be great to have an easy way to keep track of your nodes and what’s running on them? If you’re using Puppet Enterprise you have one already: it’s called PuppetDB. You can use PuppetDB with open source Puppet too.
PuppetDB automatically stores a lot of data about all of your Puppet managed nodes, including all of their facts and resources. At Puppet our Site Reliability Engineering (SRE) team uses PuppetDB as the source of truth about our Puppet managed nodes. We’ll show you how you can leverage PuppetDB to learn more about your infrastructure.
In this talk you’ll learn how to tap into your already available PuppetDB data in three ways:
We’ll also show you some ways you can make additional data available in PuppetDB, using custom facts and defines. And we’ll give you a look at a how we use these techniques on the SRE team at Puppet, including code examples.
If you haven’t mined your PuppetDB data, it’s a lot easier than you might think.
