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.

The introduction of Puppet on an infrastructure is a long and intriguing voyage without return. It requires planning, patience, method, experience, and skills, but it brings huge results.

There's definitely not a unique way to face it. In this chapter, we have exposed the general scenarios we might face, the possible alternative approaches, and have suggested a step-by-step procedure articulated in different phases: information gathering, priority setting, decision making, code development, application to production, and testing.

These phases should be reiterated at each step, with more or less emphasis on what matters to get things done.

We have also faced the changes that such a process involves: how we need a new mindset and new processes to sustain a Puppet setup.

Complementary to this is an effective management of our code: how it's versioned, reviewed, tested, and delivered to production. These are some of the topics we are going to discuss in the next chapter.
