Ansible Engine Variables Introduction

This video covers Ansible variables — what they are, where you can define them, and how precedence decides which value wins when the same variable is set in multiple places. You'll see variables defined in inventory files, host_vars/group_vars folders, playbooks, vars_files, and extra_vars on the command line, each with its own priority. It also covers creating variables dynamically through the facts module and the register attribute, which captures a task's output for later use. Mastering variables is what makes roles and playbooks reusable across different hosts and environments, and it sets up the hands-on lab where you'll put them to work.
