- Basic Linux sysadmin skills
- The course is designed for students who have little or no experience with Ansible, but are familiar with Linux systems administration concepts
- No programming or previous automation experience is required.
- If you've never logged into a Linux shell and run commands before, you will learn the Ansible syntax but you may not understand the 'why' behind the tasks that we configure. We try to explain all systems concept that we cover, but we aren't starting from the beginning with Linux in this course.

Welcome to Mastering Ansible! This course covers the goals and format. The course is divided into 6 sections, starting with Environment Setup and Foundational Concepts. For the bulk of the course, we configure a realistic 3-tier web application, refactor it, and then optimize it. We finish the course with a section on testing and troubleshooting. Prior linux systems administration experience is expected..
Configuration Management & Orchestration
Understand broad automation concepts: configuration management and orchestration. Configuration management is concerned with getting a single server into a desired state. Orchestration is focused on executing tasks in a specific order across one or many hosts. Throughout this course, we'll use Ansible to do both.
