{{% capture overview %}}
This task shows you how to debug a StatefulSet.
{{% /capture %}}
{{% capture prerequisites %}}
* You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster.
* You should have a StatefulSet running that you want to investigate.

## Debugging a StatefulSet
In order to list all the pods which belong to a StatefulSet, which have a label `app=myapp` set on them,
you can use the following:
```shell
kubectl get pods -l app=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/manage-stateful-set/delete-pods/) task for
instructions on how to deal with them.
You can debug individual Pods in a StatefulSet using the
[Debugging Pods](/docs/tasks/debug-application-cluster/debug-pod-replication-controller/) guide.
