Hi @hmlkao. 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.

Removed according to current Deployment template.

.Values.server.statefulSet.labels is used to add labels to StatefulSet itself, not pods.

@hmlkao Thanks for the contribution!

Could you please add all the deploymentAnnotations in the values.yaml file?

[Xtigyro]

@hmlkao Also - we're in the middle of a transition to a new repo for the Prometheus Helm charts. Where would you like this PR to be merged - here or in the new repo (https://github.com/prometheus-community/helm-charts/tree/main/charts/prometheus)?

[scottrigby]

See #23692. We're ready to deprecate stable/prometheus in favor of the new repo. Can this PR please be opened over there instead?

[Xtigyro]

@hmlkao The only option has become the new repo. Please open the same PR there if it's okay for ya. Apologies for the double effort!

@scottrigby Agreed.
