title: Configure a Pod Quota for a Namespace
---


{% capture overview %}

This page shows how to set a quota for the total number of Pods that can run
in a namespace. You specify quotas in a
[ResourceQuota](/docs/api-reference/{{page.version}}/#resourcequota-v1-core)
object.

## Create a namespace

Create a namespace so that the resources you create in this exercise are
isolated from the rest of your cluster.

```shell
kubectl create namespace quota-pod-example
```

## Create a ResourceQuota

Here is the configuration file for a ResourceQuota object:

{% include code.html language="yaml" file="quota-pod.yaml" ghlink="/docs/tasks/administer-cluster/quota-pod.yaml" %}

Create the ResourceQuota:

```shell
kubectl create -f https://k8s.io/docs/tasks/administer-cluster/quota-pod.yaml --namespace=quota-pod-example
```

View detailed information about the ResourceQuota:

```shell
kubectl get resourcequota pod-demo --namespace=quota-pod-example --output=yaml
```

The output shows that the namespace has a quota of two Pods, and that currently there are
no Pods; that is, none of the quota is used.

```yaml
spec:
  hard:
    pods: "2"
status:
  hard:
    pods: "2"
  used:
    pods: "0"
```

Here is the configuration file for a Deployment:

{% include code.html language="yaml" file="quota-pod-deployment.yaml" ghlink="/docs/tasks/administer-cluster/quota-pod-deployment.yaml" %}

In the configuration file, `replicas: 3` tells Kubernetes to attempt to create three Pods, all running the same application.

Create the Deployment:

```shell
kubectl create -f https://k8s.io/docs/tasks/administer-cluster/quota-pod-deployment.yaml --namespace=quota-pod-example
```

View detailed information about the Deployment:

```shell
kubectl get deployment pod-quota-demo --namespace=quota-pod-example --output=yaml
```

The output shows that even though the Deployment specifies three replicas, only two
Pods were created because of the quota.

```yaml
spec:
  ...
  replicas: 3
...
status:
  availableReplicas: 2
...
lastUpdateTime: 2017-07-07T20:57:05Z
    message: 'unable to create pods: pods "pod-quota-demo-1650323038-" is forbidden:
      exceeded quota: pod-demo, requested: pods=1, used: pods=2, limited: pods=2'
```

## Clean up

Delete your namespace:

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