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.
Authors 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.
- Explore Ansible configuration management and deployment
- Manage Linux, Windows, and network devices
- Learn how to apply Ansible best practices
- Understand how to use the new collections format
- Create custom modules and plug-ins
- Generate reusable Ansible content for open source middleware
- Build container images, images for cloud instances, and cloud infrastructure
- Automate CI/CD development environments
- Learn how to use Ansible Automation Platform for DevOps

This book is best read start to finish, with later chapters building on earlier ones. Because it's written in a tutorial style, you can follow along on your own machine. Most examples focus on web applications.
The third edition takes the reader to the next level in running Ansible for mission-critical work. Using software engineering methods to validate code quality and test frameworks to verify results in a test setup eradicates the guesswork and assumptions. Ansible 2.10 runs best with Python 3.8.
