Ansible

A standalone path through Ansible, the agentless automation tool. Beginner covers the push model, installing Ansible and inventory, ad-hoc commands and modules, and your first playbook. Intermediate is the real toolkit: variables and facts, templates with Jinja2, roles and reuse, and handlers/idempotency. Advanced goes deep: Ansible Vault for secrets, dynamic inventory and delegation, hardening playbooks and controller security, and running Ansible in CI/CD. Real playbooks and command output throughout; each level ends with a self-test feeding a rotating final exam.
