Hi @bodgit. 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.

Thanks for the PR @bodgit. Could you remove the Chart.yaml changes?

@stevehipwell done, I wasn't sure if it was just version bumps or any sort of change.

@bodgit I've added a syntax suggestion to the ExternalDNS PR.

@stevehipwell can you take a look here? thanks!

[stevehipwell]

@bodgit I've explicitly added the feedback here.

[stevehipwell]

@cpanato any idea why the Cosign installer is failing?

[cpanato]

@bodgit please rebase this PR to get the latest changes, that might fix the ci error

[stevehipwell]

Sorry @cpanato I thought I'd commented on all of the PRs failing Helm chart validation due to needing a rebase.

[cpanato]

no worries :)
