- Fixed a bug in the Job controller that could result in creating unnecessary Pods for Jobs already marked as finished (either successful or failed). ([#130333](https://github.com/kubernetes/kubernetes/pull/130333), [@kmala](https://github.com/kmala)) [SIG Apps and Testing]

  Similarly you can also access  kubelet's `/pods` endpoint to fetch a list of Pods bound to that node by granting the caller `nodes/pods` permission in RBAC.
  Similarly you can also access kubelet's `/configz` endpoint to fetch kubelet's configuration by granting the caller `nodes/configz` permission in RBAC.

Troubleshoot workloads that crash on startup by creating a copy of the pod that uses a different container image or command.
Troubleshoot distroless containers by adding a new container with debugging tools, either in a new copy of the pod or using an ephemeral container. (Ephemeral containers are an alpha feature that are not enabled by default.)
