Hi @evanfreed. 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/test-infra repository.

@evanfreed Please run make modules and make verify-modules and try pushing the PR again.

[evanfreed]

Sorry for the delay, I had some time off so I didn't look at this. I repushed after running make modulesand make verify-modules. Looks like there was an update to the go mod file, must have snuck in with a different commit but should be fixed up 🤞

Hi! I'm working on a PR where I would love to feature gate support -- is there anything I can do to help this PR get merged?

[evanfreed]

@eaceaser sorry for the delay in response, I was on vacation for a bit. I think we're good here now that I rebased, I'm just waiting for a review.

@sayantani11 @fabriziopandini or @sbueringer would you be willing to take a look? 🙏 thanks in advanced

@evanfreed Fabrizio and I are mostly in the reviewer list because maintainers of core CAPI were synced into the OWNERS file of CAPG.

No worries! Thanks @sbueringer
