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
