Extending Puppet - Second Edition

By: Alessandro Franceschi, Jaime Soriano Pastor

Overview of this book

Puppet has changed the way we manage our systems, but Puppet itself is changing and evolving, and so are the ways we are using it. To tackle our IT infrastructure challenges and avoid common errors when designing our architectures, an up-to-date, practical, and focused view of the current and future Puppet evolution is what we need. With Puppet, you define the state of your IT infrastructure, and it automatically enforces the desired state. This book will be your guide to designing and deploying your Puppet architecture. It will help you utilize Puppet to manage your IT infrastructure. Get to grips with Hiera and learn how to install and configure it, before learning best practices for writing reusable and maintainable code. You will also be able to explore the latest features of Puppet 4, before executing, testing, and deploying Puppet across your systems. As you progress, Extending Puppet takes you through higher abstraction modules, along with tips for effective code workflow management. Finally, you will learn how to develop plugins for Puppet - as well as some useful techniques that can help you to avoid common errors and overcome everyday challenges.

Puppet continuous integration


We have reviewed the tools than can accompany our code from creation to production.

Whatever happens after we commit and eventually approve our code can be automated.

It is basically a matter of executing commands on local or remote systems that use tools like the ones we have seen in this chapter for the various stages of a deployment workflow.

Once we have these single bricks that fulfill a specific function, we can automate the whole workflow with a Continuous Integration (CI) tool that can run each step in an unattended way and proceed to the following if there are no errors.

There are various CI tools and services available; we will concentrate on a pair of them, particularly popular in the Puppet community:

  • Travis: An online CI as a service tool

  • Jenkins: The well known and widely used Hudson fork

Travis

Travis (https://travis-ci.org) is an online Continuous Integration service that perfectly integrates with GitHub.

It can be used to run tests of any kind, in...
