Building Ansible's playbook

An Ansible playbook is the fundamental element in Ansible that declares what actions we would like to perform on our managed hosts (specified in the inventory). An Ansible playbook is a YAML-formatted file that defines a list of tasks that will be executed on our managed devices. In this recipe, we will outline how to write an Ansible playbook and how to define the hosts that will be targeted by this playbook.

Getting ready

In order to follow along with this recipe, an Ansible inventory file must already be defined, along with all the group- and host-specific variable files created in accordance with previous recipes.
