Hi @Revolution1. 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.

Hi, I've tested this locally and it looks good. I created a service in namespace kube-system, 2 pods in namespace echoserver and used the yaml file below. I had to add a security group rule to the cluster for it to succeed. Looping in @shraddhabang to add the ok-to-test label.
