问题

• Failed to watch *v1beta1.PodDisruptionBudget: failed to list *v1beta1.PodDisruptionBudget: the server could not find the requested resource
• no kind "KubeSchedulerConfiguration" is registered for version "componentconfig/v1alpha1"

问题原因

升级了k8s集群，但是scheduler镜像没有升级。API version过时。

解决方案

1. 升级scheduler镜像
2. 并将老的scheduler配置的apiVersion升级
   For v1.25 ~ v1.28:
   • apiVersion: kubescheduler.config.k8s.io/v1
     or
   • apiVersion: kubescheduler.config.k8s.io/v1beta3
