<!--
|

Before you do this exercise, do the exercise in
|
||||
[Advertise Extended Resources for a Node](/docs/tasks/administer-cluster/extended-resource-node/).
|
||||
That will configure one of your Nodes to advertise a dongle resource.
|
||||
-->
|
||||
|
||||
在您开始此练习前，请先练习[为节点广播扩展资源](/docs/tasks/administer-cluster/extended-resource-node/)。
|
||||
在那个练习中将配置您的一个节点来广播 dongle 资源。

## Assign an extended resource to a Pod
|
||||
|
||||
To request an extended resource, include the `resources:requests` field in your
|
||||
Container manifest. Extended resources are fully qualified with any domain outside of
|
||||
`*.kubernetes.io/`. Valid extended resource names have the form `example.com/foo` where
|
||||
`example.com` is replaced with your organization's domain and `foo` is a
|
||||
descriptive resource name.
|
||||
|
||||
Here is the configuration file for a Pod that has one Container:
|
||||
-->
|
||||
|
||||
## 给 Pod 分派扩展资源
|
||||
|
||||
要请求扩展资源，需要在您的容器清单中包括 `resources:requests` 字段。
|
||||
扩展资源可以使用任何完全限定名称，只是不能使用 `*.kubernetes.io/`。
|
||||
有效的扩展资源名的格式为 `example.com/foo`，其中 `example.com` 应被替换为您的组织的域名，而 `foo` 则是描述性的资源名称。
|
||||
|
||||
下面是包含一个容器的 Pod 配置文件：
|
||||
|
||||
{{< codenew file="pods/resource/extended-resource-pod.yaml" >}}
|
||||
|
||||
<!--
|
||||
In the configuration file, you can see that the Container requests 3 dongles.
|
||||
|
||||
Create a Pod:
|
||||
-->
|
||||
|
||||
在配置文件中，您可以看到容器请求了 3 个 dongles。
|
||||
|
||||
创建 Pod：
|
||||
|
||||
```shell
|
||||
kubectl create -f https://k8s.io/examples/pods/resource/extended-resource-pod.yaml
|
||||
```
|
||||
|
||||
<!--
|
||||
Verify that the Pod is running:
|
||||
-->
|
||||
|
||||
检查 Pod 是否运行正常：
|
||||
|
||||
```shell
|
||||
kubectl get pod extended-resource-demo
|
||||
```
|
||||
|
||||
<!--
|
||||
Describe the Pod:
|
||||
-->
|
||||
|
||||
描述 Pod:
|
||||
|
||||
```shell
|
||||
kubectl describe pod extended-resource-demo
|
||||
```
|
||||
|
||||
<!--
|
||||
The output shows dongle requests:
|
||||
-->
|
||||
|
||||
输出结果显示 dongle 请求如下：
|
||||
|
||||
```yaml
|
||||
Limits:
|
||||
example.com/dongle: 3
|
||||
Requests:
|
||||
example.com/dongle: 3
|
||||
```
|
||||
|
||||
<!--
|
||||
## Attempt to create a second Pod
|
||||
|
||||
Here is the configuration file for a Pod that has one Container. The Container requests
|
||||
two dongles.
|
||||
-->
|
||||
|
||||
## 尝试创建第二个 Pod
|
||||
|
||||
下面是包含一个容器的 Pod 配置文件，容器请求了 2 个 dongles。
|
||||
|
||||
{{< codenew file="pods/resource/extended-resource-pod-2.yaml" >}}
|
||||
|
||||
<!--
|
||||
Kubernetes will not be able to satisfy the request for two dongles, because the first Pod
|
||||
used three of the four available dongles.
|
||||
|
||||
Attempt to create a Pod:
|
||||
-->
|
||||
|
||||
Kubernetes 将不能满足 2 个 dongles 的请求，因为第一个 Pod 已经使用了 4 个可用 dongles 中的 3 个。
|
||||
|
||||
尝试创建 Pod：
|
||||
|
||||
```shell
|
||||
kubectl create -f https://k8s.io/examples/pods/resource/extended-resource-pod-2.yaml
|
||||
```
|
||||
|
||||
<!--
|
||||
Describe the Pod
|
||||
-->
|
||||
|
||||
描述 Pod
|
||||
|
||||
```shell
|
||||
kubectl describe pod extended-resource-demo-2
|
||||
```
|
||||
|
||||
<!--
|
||||
The output shows that the Pod cannot be scheduled, because there is no Node that has
|
||||
2 dongles available:
|
||||
-->
|
||||
|
||||
输出结果表明 Pod 不能被调度，因为没有一个节点上存在两个可用的 dongles。
|
||||
|
||||
```
|
||||
Conditions:
|
||||

||||

||||

|
||||
```
|
||||
|
||||
<!--
|
||||
View the Pod status:
|
||||
-->
|
||||
|
||||
查看 Pod 的状态：
|
||||
|
||||
```shell
|
||||
kubectl get pod extended-resource-demo-2
|
||||
```
|
||||
|
||||
<!--
|
||||
The output shows that the Pod was created, but not scheduled to run on a Node.
|
||||
It has a status of Pending:
|
||||
-->
|
||||
|
||||
输出结果表明 Pod 虽然被创建了，但没有被调度到节点上正常运行。Pod 的状态为 Pending：
|
||||
|
||||
```yaml
|
||||
NAME READY STATUS RESTARTS AGE
|
||||
extended-resource-demo-2 0/1 Pending 0 6m
|
||||
```
|
||||
|
||||
<!--
|
||||
## Clean up
|
||||
|
||||
Delete the Pods that you created for this exercise:
|
||||
-->
|
||||
|
||||
## 环境清理
|
||||
|
||||
删除本练习中创建的 Pod：
|
||||
|
||||
```shell
|
||||
kubectl delete pod extended-resource-demo
|
||||
kubectl delete pod extended-resource-demo-2
