To get the most out of this book

All the chapters of this book assume you have access to at least one Linux machine running a relatively recent Linux distribution. All examples in this book were tested on Fedora 38 and Ubuntu Server 22.04, but should work on just about any other mainstream distribution. You will require Ansible 2.15 installed on at least one test machine too – the installation steps will be covered in the very first chapter. Later versions of Ansible should also work, though there may be some subtle differences, and you should refer to the release notes and porting guide for newer Ansible versions. The final two chapters also take you through the installation of AWX, but this assumes a Linux server with Ansible installed. Most of the examples demonstrate automation across more than one host, and, if you have more Linux hosts available, you will be able to get more out of the examples; however, they can be scaled up or down as you require. Having more hosts is not mandatory, but enables you to get more out of the book.
