This should target 'dev-1.25' branch rather than 'main'.

I would make it clear that minReadySeconds is really there to phase the rollout of new or updated StatefulSets (whereas probe thresholds are the right thing to use if you want to, eg, see that the Pod has had a healthcheck every 2 seconds and that there have been 30 successful ones, which implies that the Pod is ready for traffic).

Good suggestion, but we also say that here https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#rolling-updates.

Please let me know if you are satisfied with the current state.

I'd like to repeat that detail under the Minimum Ready Seconds heading, in case people didn't arrive via https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#rolling-updates.

@sftim looks like this was merged without the comment being addressed, do we need any further followup?

It'd be nice to fix that, but that fix can happen after v1.25 ships.

I can post an update, but what are problems with this approach? ^

This should be against dev-1.25 branch, since that's covering a feature going GA in 1.25
