* Add microk8s to foundational.md

Adding microk8s as credible and stable alternative to get started with Kubernetes on a local machine. This is especially attractive for those not wanting to incur the overhead of running a VM for a local cluster.

给节点添加标签

  1. 列出集群中的节点

     kubectl get nodes
    

    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. 选择其中一个节点,为它添加标签:

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

    <your-node-name> 是你选择的节点的名称。

  1. 验证你选择的节点是否有 disktype=ssd 标签:

    kubectl get nodes --show-labels
    

    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
    

    在前面的输出中,你可以看到 worker0 节点有 disktype=ssd 标签。

创建一个调度到你选择的节点的 pod

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. 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. 验证 pod 是不是运行在你选择的节点上:

     kubectl get pods --output=wide
    

    输出类似如下:

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