services.nodeports: "0"
```

## Create a PersistentVolumeClaim

Here is the configuration file for a PersistentVolumeClaim object:

{{% code_sample file="admin/resource/quota-objects-pvc.yaml" %}}

Create the PersistentVolumeClaim:

```shell
kubectl apply -f https://k8s.io/examples/admin/resource/quota-objects-pvc.yaml --namespace=quota-object-example
```

Verify that the PersistentVolumeClaim was created:

```shell
kubectl get persistentvolumeclaims --namespace=quota-object-example
```

The output shows that the PersistentVolumeClaim exists and has status Pending:

```
NAME             STATUS
pvc-quota-demo   Pending
```

## Attempt to create a second PersistentVolumeClaim

Here is the configuration file for a second PersistentVolumeClaim:

{{% code_sample file="admin/resource/quota-objects-pvc-2.yaml" %}}

Attempt to create the second PersistentVolumeClaim:

```shell
kubectl apply -f https://k8s.io/examples/admin/resource/quota-objects-pvc-2.yaml --namespace=quota-object-example
```

The output shows that the second PersistentVolumeClaim was not created,
because it would have exceeded the quota for the namespace.

```
persistentvolumeclaims "pvc-quota-demo-2" is forbidden:
exceeded quota: object-quota-demo, requested: persistentvolumeclaims=1,
used: persistentvolumeclaims=1, limited: persistentvolumeclaims=1
```

## Notes

These are the strings used to identify API resources that can be constrained
by quotas:

<table>
<tr><th>String</th><th>API Object</th></tr>
<tr><td>"pods"</td><td>Pod</td></tr>
<tr><td>"services"</td><td>Service</td></tr>
<tr><td>"replicationcontrollers"</td><td>ReplicationController</td></tr>
<tr><td>"resourcequotas"</td><td>ResourceQuota</td></tr>
<tr><td>"secrets"</td><td>Secret</td></tr>
<tr><td>"configmaps"</td><td>ConfigMap</td></tr>
<tr><td>"persistentvolumeclaims"</td><td>PersistentVolumeClaim</td></tr>
<tr><td>"services.nodeports"</td><td>Service of type NodePort</td></tr>
<tr><td>"services.loadbalancers"</td><td>Service of type LoadBalancer</td></tr>
</table>

## Clean up

Delete your namespace:

```shell
kubectl delete namespace quota-object-example
```
