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.

Git workflows

In this section, we will review:

  • The Git basic principles and commands

  • Some useful Git hooks

Code management using Git

Git is generally available as the native package in every modern OS. Once we have installed it, we can configure our name and e-mail (that will appear in all our commits) with:

git config --global "Alessandro Franceschi"
git config --global [email protected]

These commands simply create the relevant entries in the ~/.gitconfig file. We can add more configurations either by directly editing this file or with the git config command, and check their current values with git config -l.

To create a Git repository, we just have to move into the directory that we want to track and simply type git init. This command initializes...
