Hi @josvazg. 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.

Last nit from my side, apart from the CLA.

I'll test this PR on my fork by cutting a release there

[sbueringer]

All good. Here is a test release: https://github.com/sbueringer/controller-tools/releases/tag/v0.16.3-beta.0

Checked the controller-gen-darwin-arm64 binary:

 ./controller-gen-darwin-amd64 --version
Version: v0.16.3-beta.0

Hopefully the CLA will be sorted out soon now, maybe tomorrow.

[josvazg]

CLA sorted, we can proceed now I guess.
