Chapter 1: Build Your Practice Lab

Build a sealed, classroom-style practice lab at home, with Rocky Linux 9 VMs on LXD using the classroom's names, addresses and users, so you can try every exercise in this guide.

What you will learn

• Prepare an Ubuntu host with LXD and create a private lab network that nothing outside can connect into.
• Build workstation and servera to serverd with a cloud-init profile that creates the classroom users.
• Set up workstation as an Ansible control node with ansible-core 2.14 and ansible-navigator.
• Reset machines between exercises with snapshots and a classroom-compatible rht-vmctl command.
