Ansible Playbook Essentials

By: Gourav Shah, GOURAV JAWAHAR SHAH

Overview of this book

Ansible Playbook Essentials will show you how to write a blueprint of your infrastructure, encompassing multitier applications using Ansible's playbooks. Beginning with basic concepts such as plays, tasks, handlers, inventory, and YAML Ain't Markup Language (YAML) syntax that Ansible uses, you'll understand how to organize your code into a modular structure. Building on this, you will study techniques to create data-driven playbooks with variables, templates, logical constructs, and encrypted data, which will further strengthen your application skills in Ansible. Adding to this, the book will also take you through advanced clustering concepts, such as discovering topology information about other nodes in the cluster and managing multiple environments with isolated configurations. As you approach the concluding chapters, you can expect to learn about orchestrating infrastructure and deploying applications in a coordinated manner. By the end of this book, you will be able to design solutions to your automation and orchestration problems using playbooks quickly and efficiently.

Review questions


Do you think you've understood the chapter well enough? Try answering the following questions to test your understanding:

  1. Roles contain ___ and ___ subdirectories to specify variables/parameters.

  2. How do you specify a dependency on another role?

  3. When we add roles to a play, why is it not required that we use the include directives? How do the tasks, handlers, and so on, get added to the play automatically?

  4. Why do we have a separate section for handlers if they resemble regular tasks?

  5. Which module can be used to copy over static files to destination hosts?

  6. How do you specify the tasks to be run before applying a role in a playbook?
