Hi @Jamstah. Thanks for your PR.

I'm waiting for a openshift 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.

@Jamstah thanks for submitting this! Something funky is going on with our tests, but I'll help move this along (need to get engineering/QE review as well).

I'll probably have some nits about the files - are you okay with making the updates if I point them out (and then squashing the commits afterward), or would you prefer me to take over the PR to make those final updates?

The branch/enterprise-4.19 label has been added to this PR.

This is because your PR targets the main branch and is labeled for enterprise-4.18. And any PR going into main must also target the latest version branch (enterprise-4.19).

If the update in your PR does NOT apply to version 4.19 onward, please re-target this PR to go directly into the appropriate version branch or branches (enterprise-4.x) instead of main.

[Jamstah]

@tkashem @wangke19 please review :)

[Jamstah]

@bergerhoffer is there anyone else who can approve?

[bergerhoffer]

Sorry for the delay, I've pinged again, we'll try to get someone soon.
