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.

Write Puppet code


Each of us has a favorite tool for code writing. It may change according to the language we are using, our familiarity with the software or a preference of the moment.

Whatever tool we use, it should make our experience as smooth, productive, and enjoyable as possible.

I am a Vim guy, without being a guru. Having a system admin background, grown with bread and shell, I am comfortable with the possibility of using the same tool, wherever I am, on the local terminal or the remote SSH session: more or less we can expect to find Vim on any system under our keyboard.

A developer, I guess, may feel more comfortable with a tool that runs on his computer and can greatly enhance the writing experience, with syntax checks, cross references, and all the power of an IDE.

For this, there is Geppetto, a full-featured IDE, based on Eclipse and dedicated to Puppet code. Other popular editors also have Puppet plugins that can be quite useful.

The good news is that all of them can make life more...
