• Update labels, using named templates, to be in line with current best practices. Major version bump, due to the scope and potentially breaking changes.
  • https://kubernetes.io/docs/concepts/overview/working-with-objects/common-labels/#labels
  • https://docs.helm.sh/chart_best_practices/#standard-labels
  • See discussion here: Putting chart version in metadata.labels in a Deployment v1beta1 without selector prevents upgrade #7726

Hi @yurrriq. Thanks for your PR.

I'm waiting for a helm 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.

Should we discuss this during the next meeting? #7696 has been closed due to lack of activity.

[yurrriq]

I could join the discussion on 11/29.

[mattfarina]

This PR is a breaking change for people operating Redis because the matchLabels and volume lablels change. A painful change just for labels is one I'm not sure I want to put forth.

It may make more sense to do this when it moves to the distributed search and some other large changes land.

[mattfarina]

This is a neat method to avoid repeating the same things.

Any chance this could be made the default?
