Hi @asmigala. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

Hello @howardjohn @candita

Could you response, please?
This fix will unlock the conformance testing on openshift clusters.

Is there anything that prevents from merging this?

[candita]

@MaxBab we haven't found this to be an issue. What version/s and platform are you testing?

Hello @candita

This issue happens on Openshift platform.

Hello @candita

Let's chat. I sent you a slack message.

@asmigala Can you fix the language and commit comment that makes it seem like it's the only way that conformance reports will run on OpenShift. This helps OpenShift, but isn't the only way to do it and thus isn't required by all OpenShift testing. Seems like it's not really a bug, in my opinion.

Would it be reasonable for us to just change the port and update the svc targetPort?
