What is this Ansible Tutorial?

Configuration management is how you ensure every server in your fleet is set up correctly, consistently, and automatically. Instead of SSH-ing into 50 servers and running commands one by one, you write a playbook once and let Ansible do the work.

This tutorial teaches you Ansible from scratch. We start with installation and a single ad-hoc command, then build up to playbooks, variables, roles, templates, and vault-encrypted secrets.
