In this chapter, you learned:
A play is an ordered list of tasks, which runs against hosts selected from the inventory.
A playbook is a text file that contains a list of one or more plays to run in order.
Ansible Playbooks are written in YAML format.
YAML files are structured using space indentation to represent the data hierarchy.
Tasks are implemented using standardized code packaged as Ansible modules.
The ansible-doc command can list installed modules, and provide documentation and example code snippets of how to use them in playbooks.
The ansible-playbook command is used to verify playbook syntax and run playbooks.
Click CREATE to build all of the virtual machines needed for the classroom lab environment. This may take several minutes to complete. Once created the environment can then be stopped and restarted to pause your experience.
If you DELETE your lab, you will remove all of the virtual machines in your classroom and lose all of your progress.
