--- title: Configure a Pod Quota for a Namespace content_template: templates/task weight: 60 --- {{% 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. {{% /capture %}} {{% capture prerequisites %}} {{< include "task-tutorial-prereqs.md" >}} {{< version-check >}} {{% /capture %}} {{% capture steps %}} ## 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: {{< codenew file="admin/resource/quota-pod.yaml" >}} Create the ResourceQuota: ```shell kubectl create -f https://k8s.io/examples/admin/resource/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: {{< codenew file="admin/resource/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/examples/admin/resource/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 ``` {{% /capture %}} {{% capture whatsnext %}} ### For cluster administrators * [Configure Default Memory Requests and Limits for a Namespace](/docs/tasks/administer-cluster/memory-default-namespace/) * [Configure Default CPU Requests and Limits for a Namespace](/docs/tasks/administer-cluster/cpu-default-namespace/) * [Configure Minimum and Maximum Memory Constraints for a Namespace](/docs/tasks/administer-cluster/memory-constraint-namespace/) * [Configure Minimum and Maximum CPU Constraints for a Namespace](/docs/tasks/administer-cluster/cpu-constraint-namespace/) * [Configure Memory and CPU Quotas for a Namespace](/docs/tasks/administer-cluster/quota-memory-cpu-namespace/) * [Configure Quotas for API Objects](/docs/tasks/administer-cluster/quota-api-object/) ### For app developers * [Assign Memory Resources to Containers and Pods](/docs/tasks/configure-pod-container/assign-memory-resource/) * [Assign CPU Resources to Containers and Pods](/docs/tasks/configure-pod-container/assign-cpu-resource/) * [Configure Quality of Service for Pods](/docs/tasks/configure-pod-container/quality-service-pod/) {{% /capture %}}
