Summary

In this chapter, you learned about what Ansible playbooks are, what components those are made up of, and how to blueprint your infrastructure with it. We also did a primer on YAML—the language used to create plays. You learned about how plays map tasks to hosts, how to create a host inventory, how to filter hosts with patterns, and how to use modules to perform actions on our systems. We then created a simple playbook as a proof of concept.

In the upcoming chapter, we will start refactoring our code to create reusable and modular chunks of code, and call them roles.
