PuppetConf 2016

With Puppet, you can declare what you want your infrastructure to look like and Puppet will take action, making the necessary changes to bring it to fruition. How do you know if your Puppet declarations have produced a working stack? Will future changes impact the health of your stack? In this presentation, I will discuss common pitfalls and failure cases when using Puppet to manage infrastructure and services, and how they can be mitigated or avoided with monitoring. I will talk about Sensu, a monitoring tool designed from the ground up to work in conjunction with Puppet. I will explain how Puppet and Sensu interact with one another to help produce reliable services. This presentation will include examples of Puppet & Sensu configuration and code.
