+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/reference/generated/kubernetes-api/{{< param "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:
+
+{{< code file="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:
+
+{{< code file="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
+```
