- Understand the lab topology, provided hardware (if applicable), and how to access virtual instances (again, if applicable).
- Understand how to use the workshop exercises.
These first few lab exercises will be exploring the lab and gathering baseline information for use in later excercises.
In this lab, you work in a pre-configured lab environment and will have access to the following services:
| Service | Purpose |
|---|---|
| Ansible Controller | Automation controller for running Ansible automation |
| Gitea Source Control | SCM with a webUI for code storage |
| rpm-ostree Repo | Repo with various versions of an edge image available over an http server |
Since this is a shortened lab, the Image Builder related steps have already been completed, and images are hosted and ready for consumption.

- If physical devices are available at your lab station, proceed to Step 2 - Investigating the Edge Device
- If a physical device is not available at your lab station, proceed to Step 3 - Accessing the Virtual Device Host
- A device should be available at your station, along with the usual swite of peripherals (keyboard, mouse, monitor, cables).
- There may be doubling up of students to devices depending on availability.
A baremetal instance has been created in RHPDS that will host virtual instances meant to represent an edge device. Your "Workbench Information" page that lists credentials to the various services includes a link to the Image Builder Cockpit interface. This is the machine on which your VMs are hosted. You can, alternatively, SSH to the instance using the Edge Manager SSH Access and interact with your VMs using traditional command line tooling, virt-manager with a remote connection configured on your host, or any other access method you might prefer.
It is highly encouraged that the Cockpit web interface be used to complete the workshop exercises. Cockpit provides:
- An easy to access interface to managing virtual machines running on RHEL
- Tooling for creating, starting, and stopping virtual machines
- A web based console for bootstraping and troubleshooting
