Chapter 2. Going Modular with Ansible Roles

In the last chapter, you learned about writing a simple playbook with Ansible. You also learned about the concepts of plays which map hosts to tasks. Writing tasks in a single playbook may work fine for a very simple setup. However, if we have multiple applications spanning across number of hosts, this will quickly become unmanageable.

In this chapter, you will be introduced to the following concepts:

What makes a role and what are roles used for?
How to create roles to provide abstraction?
Organizing content to provide modularity
Using include statements
Writing simple tasks and handlers
Installing packages, managing services, and serving files with Ansible modules
