Ⅰ. Describe what this PR does

Add inPlaceUpdate restart count to annotation.
the result is shown below:
Annotations:

apps.kruise.io/inplace-update-containers-restart-count: '{"nginx":{"revision":"sample-d97f89dcf","restartCount":1,"timestamp":"2022-03-24T08:03:23Z"},"sidecar":{"revision":"sample-d97f89dcf","restartCount":1,"timestamp":"2022-03-24T08:03:23Z"}}'
apps.kruise.io/inplace-update-pod-restart-count: "2"

apps.kruise.io/inplace-update-pod-restart-count: The Pod restart count.
apps.kruise.io/inplace-update-containers-restart-count: Every container restart count of the pod.
(revision: the revision of the container updated.)

The revision and timestamp maybe is different between the containers when we just update one(or a part of containers in the pod) container of the pod.Because we just update the restart count of the container when it will be updated(inplace-update).

It's not an in-place upgrade here, and it doesn't feel like it should be judged

Hi @diannaowa
I have few questions:

The modifications seem to target the InPlaceUpdateContainersRestartKey and InPlaceUpdatePodRestartKey primarily in the following scenarios:

  • When patch a pod during an in-place update.
  • When finish Grace Period.
  • When update Next Batch container need to in-place update.

Specifically, the action taken is to increase the restart count for containers which will in-place upgrade (the revision does not match the updated revision).

Is it correct to interpret that these annotations are intended to log the restart counts of containers specifically due to in-place upgrades?

I feel that tracking the restart count prior to each in-place upgrade does not provide meaningful data for the current version.

My expectation was that the restart counts for each container would be logged post-completion of an in-place upgrade, effectively resetting the count to zero. Then
abnormal restart count for the current version's containers = restart count in status - logged restart count in annotation
