Ansible Playbook Automation
Ansible only clicks once you've run a playbook against real hosts and watched idempotency actually work. This lab gives you a live control node and multiple managed targets already connected over SSH, so you write playbooks instead of debugging inventory files.
The problem
A playbook runs cleanly against a host that should already be fully converged, but every run reports changes, even on hosts nobody has touched since the last run.
What you'll practice
- Build a static inventory and group hosts by role
- Write playbooks using core modules (package, service, copy, template)
- Structure reusable roles instead of one long playbook
- Run ad-hoc commands for quick fact-gathering and one-off changes
- Verify idempotency by re-running a playbook against a converged host
The topology
An Ansible control node reaches three managed Linux hosts over SSH, enough targets to practice inventory grouping, host-pattern targeting and role reuse without a single-host toy setup.

Frequently asked
Do I need to set up SSH keys and hosts myself?
No. The control node and managed hosts are already keyed and reachable. You focus on writing playbooks, not bootstrapping SSH access.
Does this match the RH294 exam scope?
Yes. Inventories, playbooks, roles and idempotent task design are the core RH294 objectives this lab is built around.
