Hi @ccojocar. 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.

The unit tests failure on macos doesn't seem to be related to this change. It looks like a transient failure. The test passed when executed locally on macos.

Yes, I've seen those, too. I kicked the test now.

The code looks good, I just wonder if you think this is worth documenting in the installation-usage.md document?
