## Debugging a StatefulSet
|
||
|
||
In order to list all the pods which belong to a StatefulSet, which have a label `app.kubernetes.io/name=MyApp` set on them,
|
||
you can use the following:
|
||
-->
|
||
## 调试 StatefulSet {#debugging-a-statefulset}
|
||
|
||
StatefulSet 在创建 Pod 时为其设置了 `app.kubernetes.io/name=MyApp` 标签，列出仅属于某 StatefulSet
|
||
的所有 Pod 时，可以使用以下命令：
|
||
|
||
```shell
|
||
kubectl get pods -l app.kubernetes.io/name=MyApp
|
||
```
|
||
|
||
<!--
|
||
If you find that any Pods listed are in `Unknown` or `Terminating` state for an extended period of time,
|
||
refer to the [Deleting StatefulSet Pods](/docs/tasks/run-application/delete-stateful-set/) task for
|
||
instructions on how to deal with them.
|
||
You can debug individual Pods in a StatefulSet using the
|
||
[Debugging Pods](/docs/tasks/debug/debug-application/debug-pods/) guide.
|
||
-->
|
||
如果你发现列出的任何 Pod 长时间处于 `Unknown` 或 `Terminating` 状态，请参阅
|
||
[删除 StatefulSet Pod](/zh-cn/docs/tasks/run-application/delete-stateful-set/)
|
||
了解如何处理它们的说明。
|
||
你可以参考[调试 Pod](/zh-cn/docs/tasks/debug/debug-application/debug-pods/)
|
||
来调试 StatefulSet 中的各个 Pod。
