Hi @shuyanl-qualtrics. 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.

Is there any chance this PR can be reviewed by owner?

[shuyanl-qualtrics]

might not related just want to point out...
As this comment suggests, one should update values.yaml for default values. However, I'm not be able to find where to add this. I'm also trying to find out similar example in the repo but I found this hostNetwork setting but didn't see corresponding field in values.yaml.

Any help is appreciated
