Hi @eytanhanig. 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.

This is adding a feature to the chart so I think the version should be 1.2.0

[eytanhanig]

thanks for the PR! can you please run make generate-kustomize to update the kustomize templates with this change as well?

[krmichel]

thanks for the PR! can you please run make generate-kustomize to update the kustomize templates with this change as well?

The values from the values.yaml in the chart are empty dictionaries so unless they get set by some other means they won't cause any changes in the generated kustomize manifests.

[vdhanan]

ah, makes sense.
