Hi @Elbehery. 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.

@wongma7, how do you deal with decreased unit test coverage? -0.008%, that's like one line?

[wongma7]

@jsafrane yeah coveralls is too finicky, I tried increasing threshold and will remove it if that doesn't work, I'm always manually merging to get around it anyway.
