We will cover the basic concepts of inventory parsing and how data is discovered, and then proceed onto playbook parsing. We will take a walk through module preparation, transportation, and execution. Lastly, we will detail variable types and find out where the variables are located, their scope of use, and how precedence is determined when variables are defined in more than one location. All these things will be covered in order to lay the foundation for mastering Ansible!
