DO188 Course Problem: Ch 4.1 guided exercise

[Jwhite518]

I'm doing the guided exercise "Create Images with Containerfiles"

In section 3.1 we update the Containerfile with a new base image 

 and then in 4.5 we build the image, I get the following error:

"...unauthorized: access to the requested resource is not authorized"

So I can't complete the exercise.

I tried to replicate the problem in DO188 versions 4.10 and 4.12. It's working fine in both of them:

Your problem appears to be caused by an authentication problem. Make sure that you have run the "lab start" script, which authenticates Podman into the internal image registry. 

Also, from your screenshot, you seem to be using version 4.10. I'd suggest you to switch to 4.12, which is the latest release of the course.

Just realised I had been running 4.10 too.
Is there anyway to tell/show the differences to the 4.12 version?

[Jwhite518]

How do I choose course version 4.12?

[jramcast]

@Jwhite518 @DanN7 on rol.redhat.com, once you navigate to the DO188 course, you should be able to use the version selector.

Or you can just navigate to the URL for version 4.12  https://rol.redhat.com/rol/app/courses/do188-4.12/

Are there any notes on what the changs between the versions are?

[jramcast]

Unfortunately, we do not include public release notes in minor releases. In brief, we updated the OpenShift version from 4.10 to 4.12, updated the Podman version to 4.2.0 (iirc), and included Podman Desktop.

We also solved several issues and implemented minor enhancements, which you can browse in JIRA:
