With the Ansible automation tool, developers and system administrators in the enterprise can automate the provisioning, configuration, and management of distributed and on-premises systems. This study guide prepares you for the Red Hat Certified Engineer (RHCE) certification exam, 90% of which covers Ansible.

Red Hat's Alex Soto Bueno and Andrew Block walk you through all the material covered in the exam. You'll begin with foundational concepts that build on one another and then dive into specific exam topics. The performance-based RHCE exam requires a deep knowledge of Ansible systems and tasks under time pressure. This comprehensive guide is the ideal way to prepare.

Learn how Ansible can simplify your day-to-day operations
Solve real-world Ansible problems in a hands-on command-line environment
Install Ansible and set up managed environments
Use ad hoc commands and include them in scripts as requested in the exam
Prepare your Ansible configuration file and inventory file
Set up and prepare nodes, including SSH key-based authentication
Install required Ansible packages

Who Should Read This Book:
This book is written for users interested in learning how to manage their infrastructure and systems with Ansible. Since automation plays an increasingly important role in the operation of infrastructure and applications, this book is of interest to a range of personas: everyone from system administrators seeking their next certification, to junior engineers looking to master new technologies and concepts, to software architects looking to stay on top of technology trends. Users familiar with IT automation, the tools, and available common approaches will also see how Ansible is uniquely positioned to excel regardless of where it operates—on premises, in the cloud, or at the edge.

Here is an overview of what we cover in the book:
• Chapter 1 gives an overview of the topics covered in the exam and discusses the benefits of certification.
• Chapter 2 provides an introduction to Ansible, including basic concepts, and lays the groundwork for the rest of the book.
• Chapter 3 introduces Ansible Playbooks, and walks through how to run your first playbook.
• Chapter 4 focuses on how Ansible manages hosts and how to organize and target automation against them.
• Chapter 5 looks at flow control and examines how to influence the execution of automation activities.
• Chapter 6 looks at how to manipulate files in Ansible, including basic operations and templating.
• Chapter 7 is a deep dive into Ansible modules and how to develop a new module.
• Chapter 8 covers how to organize Ansible content using roles and collections, their purpose, and how they enable you to package and share Ansible content with others.
• Chapter 9 introduces Ansible Execution Environments as a method for running Ansible automation, the challenges they solve, and how they can be created.
• Chapter 10 covers how to effectively manage systems using Ansible, and looks at management-related activities, including filesystem management and security considerations.
