Create a Playbook
Explore the fundamentals of creating Ansible playbooks to automate configuration and orchestration tasks. Learn how to write playbooks in YAML that define hosts and tasks, convert ad-hoc commands into playbooks, and run them with ansible-playbook. This lesson helps you streamline automation by managing multiple tasks across host groups efficiently.
We'll cover the following...
Playbooks are the basis of configuration management, and orchestrated automation with Ansible, and are designed for automating repeatable tasks.
Playbooks are expressed in YAML and have a minimum amount of syntax. YAML is a model of a configuration or a process. Because playbooks define a process and/or configuration, they are kept in source control.
Each playbook is composed of one or more plays. A play starts by defining the hosts line. The hosts line is a list of one or more groups or host patterns separated by colons.
Optionally, you can define the user to run the play as.
The hosts line is followed by a tasks list. Ansible executes tasks in order, one at a time, against all the ...
