Description Abdul Kandathil (IBM) 2022-10-20 09:59:40 UTC

**What happened**:
Submariner addon unistallation doesnt work from ACM console due to x86 image being used by submariner-routeagent-uninstall pods.

The problem here is that the pause image (provided through k8s.gcr.io/pause) doesn't have the right architecture. k8s.gcr.io/pause is a "well-known" image name for the pause image, I was under the impression that OCP provided an appropriate image in all cases, but apparently that's not the case...

Hello Abdul,

Unfortunately, we don't have IBM Z platform to verify the fix.
Any chance you could verify the fix, please?

Thank you,
Maxim.

Yes, I can try it on my cluster. Please share the steps.
