Hi @snstanton. 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.

I thought our chart was being inconsistent naming it podAnnotations instead of just annotations like in some other places but I see now podAnnotations refers to the statefulset's pod instead of statefulset itself...

You need to rebase just because the version got bumped

Looks like the lgtm label got removed by the rebase for the version number change. There were no other code changes.

I'm not sure how to proceed. The PR was approved pending a rebase. I rebased, then the PR wasn't re-approved before it needs to be rebased again.

sorry about that
