k8s的版本是1.29

[divanodestiny]

1. kubebrain can not work well with apiserver > 1.25 due to known issue https://github.com/kubewharf/kubebrain/issues/29
2. apiserver may not get latest object in time, so it send delete request with an old revision which cause CAS failed.

I advise that you can test with apiserver <= 1.25 again.
