Workshop Exercise - Run Rollback Job

Table of Contents



In this exercise, we will demonstrate rolling back one of our pet app servers, just as we would if the RHEL upgrade had failed or if we had found the upgrade caused unexpected impact to the application.

We are now here in our exploration of the RHEL in-place automation workflow:

After rolling back, the pet app server will be restored to as it was just before entering the upgrade phase of the workflow.

Step 1 - Launch the Rollback Job Template

In this step, we will be rolling back the RHEL in-place upgrade on one of our pet application servers.

Step 2 - Observe the Rollback Job Output

After launching the rollback playbook job, the AAP Web UI will navigate automatically to the job output page.

Step 3 - Check the RHEL Version

Repeat the steps you followed with Exercise 2.3: Step 2, this time to verify that the RHEL version is reverted back.


In this exercise, we used automation to quickly reverse the RHEL in-place upgrade and restore the app server back to its original state.

In the next exercise, we’ll dig deeper to validate that all changes and impacts caused by the upgrade are now undone.
