This project is meant to house playbooks used in various demos and talks that I give. It's also meant to be used for Ansible Tower demos.
This is a fully functional Ansible project, complete with ansible.cfg, inventory, and a sane directory structure. You can initialize the lab environment by running vagrant up. This repository can also be added as a Project in Ansible Tower.
Check out my asciineema page for demos of some of the playbooks.
