## Add a label to a node
-->
## 给节点添加标签

<!--
1. List the nodes in your cluster:
-->
1. 列出集群中的节点

        kubectl get nodes

    <!--
    The output is similar to this:
    -->
    输出类似如下：

        NAME      STATUS    AGE     VERSION
        worker0   Ready     1d      v1.6.0+fff5156
        worker1   Ready     1d      v1.6.0+fff5156
        worker2   Ready     1d      v1.6.0+fff5156

<!--
1. Chose one of your nodes, and add a label to it:
-->
1. 选择其中一个节点，为它添加标签：

        kubectl label nodes <your-node-name> disktype=ssd

    <!--
    where `<your-node-name>` is the name of your chosen node.
    -->
    `<your-node-name>` 是你选择的节点的名称。

<!--
1. Verify that your chosen node has a `disktype=ssd` label:
-->
1. 验证你选择的节点是否有 `disktype=ssd` 标签：

       kubectl get nodes --show-labels


    <!--
    The output is similar to this:
    -->
    输出类似如下：

        NAME      STATUS    AGE     VERSION            LABELS
        worker0   Ready     1d      v1.6.0+fff5156     ...,disktype=ssd,kubernetes.io/hostname=worker0
        worker1   Ready     1d      v1.6.0+fff5156     ...,kubernetes.io/hostname=worker1
        worker2   Ready     1d      v1.6.0+fff5156     ...,kubernetes.io/hostname=worker2

    <!--
    In the preceding output, you can see that the `worker0` node has a
    `disktype=ssd` label.
    -->
    在前面的输出中，你可以看到 `worker0` 节点有 `disktype=ssd` 标签。

<!--
## Create a pod that gets scheduled to your chosen node
-->
## 创建一个调度到你选择的节点的 pod

<!--
This pod configuration file describes a pod that has a node selector,
`disktype: ssd`. This means that the pod will get scheduled on a node that has
a `disktype=ssd` label.
-->
该 pod 配置文件描述了一个拥有节点选择器 `disktype: ssd` 的 pod。这表明该 pod 将被调度到
有 `disktype=ssd` 标签的节点。

{{< codenew file="pods/pod-nginx.yaml" >}}

<!--
1. Use the configuration file to create a pod that will get scheduled on your
   chosen node:
-->
1. 使用该配置文件去创建一个 pod，该 pod 将被调度到你选择的节点上：

        kubectl create -f https://k8s.io/examples/pods/pod-nginx.yaml

<!--
1. Verify that the pod is running on your chosen node:
-->
1. 验证 pod 是不是运行在你选择的节点上：

        kubectl get pods --output=wide

    <!--
    The output is similar to this:
    -->
    输出类似如下：

        NAME     READY     STATUS    RESTARTS   AGE    IP           NODE
        nginx    1/1       Running   0          13s    10.200.0.4   worker0
