Hi @ivanvc. Thanks for your PR.

I'm waiting for a kubernetes 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.

@jmhbnz, can you please take a look at this?

[jmhbnz]

Thanks for raising this @ivanvc - First thing is I think we can drop lazyfs from these jobs which will simplify a bit and improve security posture.

[jmhbnz]

Getting closer now - thanks @ivanvc!

[ivanvc]

I'll redraft this. I will open it once I address the previous comments.

[jmhbnz]

Thanks @ivanvc

The tests failed because the jobs share the same testgrid-tab-name. I'll rename the tabs to match the job name.

@jmhbnz, can you approve so tests can run again? Thanks.
