THE DEV BENCH
🎛️

Ansible lab

A real control node with two managed hosts. Learn mode covers inventory, playbooks, variables and facts, handlers, templates, roles and vault; Break-fix mode fixes playbooks that fail, need privilege, or quietly report changed on every single run.

Why this matters: Configuration management is judged on idempotency — a playbook that works once is not a working playbook. Running it twice and having to explain why the second run reported changes is the exact skill that separates people who have used Ansible from people who have read about it.

Ansible — getting started

New to Ansible? Each walkthrough gives you a real control node and two managed hosts, and teaches one core idea — inventory, playbooks, variables and facts, handlers, templates, roles, vault. You run genuine playbooks against genuine machines.
