Among the many configuration management tools available, Ansible has some distinct advantages: It's minimal in nature. You don't need to install agents on your nodes. And there's an easy learning curve. With this updated third edition, you'll quickly learn how to be productive with Ansible whether you're a developer deploying code or a system administrator looking for a better automation solution. \n \nAuthors Bas Meijer, Lorin Hochstein, and Rene Moser show you how to write playbooks (Ansible's configuration management scripts), manage remote servers, and explore the tool's real power: built-in declarative modules. You'll learn how Ansible has all the functionality you need--and the simplicity you desire. \n

\nPreface to the Third Edition \n

Since the second edition of this book was published in 2017, there have been tremendous changes in the world of Ansible and Python, including several major releases. Substantial changes happened outside the project as well: for example, Red Hat, the company that backs the Ansible project, was bought by IBM. That hasn’t slowed the Ansible project at all, of course: it’s still in active development and gaining users. The development of cloud infrastructure and containers has also changed the landscape immensely.

\n

We’ve made multiple changes in this edition, most significantly adding six new chapters that cover containers, Molecule, Ansible collections, creating images, cloud infrastructure, and CI/CD. We’ve also added much more detail to other chapters, with a focus on using software engineering best practices and test frameworks to validate code and eradicate guesswork.

\n

We’ve updated all the example code for compatibility with the latest Ansible, as well as everything that addresses Python dependencies. Our material was written to reflect the significant changes between 2017 and 2022. We could go on, but we hope you’ll dive into the text, try the code, and discover for yourself just how much Ansible continues to advance.
