<!--
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.
-->
本文介绍怎样给命名空间配置可以运行的 Pod 总数配额。你在 [ResourceQuota](/docs/reference/generated/kubernetes-api/{{< param "version" >}}/#resourcequota-v1-core)对象中可以进行声明。

## Create a namespace
Create a namespace so that the resources you create in this exercise are
isolated from the rest of your cluster.
-->
## 创建命名空间
创建一个命名空间,以便本练习所创建的资源和集群的其余资源相隔离。
```shell
kubectl create namespace quota-pod-example
```
<!--
## Create a ResourceQuota
Here is the configuration file for a ResourceQuota object:
-->
## 创建一个 ResourceQuota
这里给出了一个 ResourceQuota 对象的配置文件:
{{< codenew file="admin/resource/quota-pod.yaml" >}}
<!--
Create the ResourceQuota:
-->
创建 ResourceQuota
```shell
kubectl create -f https://k8s.io/examples/admin/resource/quota-pod.yaml --namespace=quota-pod-example
```
<!--
View detailed information about the ResourceQuota:
-->
查看 ResourceQuota 详情:
```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.
-->
输出结果显示该命名空间有两个 Pod 的配额,并且当前没有 Pod;也就是配额没有被使用。
```yaml
spec:
hard:
pods: "2"
status:
hard:
pods: "2"
used:
pods: "0"
```
<!--
Here is the configuration file for a Deployment:
-->
这里给出了一个 Deployment 的配置文件:
{{< 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:
-->
配置文件中,`replicas: 3` 使 Kubernetes 尝试创建3个 Pod,都运行相同的应用。
创建 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:
-->
查看 Deployment 详情:
```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.
-->
输出结果显示尽管 Deployment 声明了三个副本,但由于配额的限制只创建了两个 Pod。
```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:
-->
## 清理环境
删除你的命名空间:
```shell
kubectl delete namespace quota-pod-example
```
