### pod示例 ###

*  vim pod.yaml

apiVersion: v1
    kind: Pod
    metadata:
      name: myapp-pod
      namespace: default #默认就是default的名称空间
      labels: 
        app: myapp
        version: v1
    spec:
      containers:
      - name: app
        image: hub.atguigu.com/library/myapp:v1
      - name: test
        image: hub.atguigu.com/library/myapp:v1

*  创建

kubectl create-f pod.yaml 或 
    kubectl apply -f pod.yaml
    kubectl get pod

*  上述一个pod中两个容器都没有指定端口，默认都是80端口，启动会报错，因此会不断重启，查看日志：

kubectl log myapp-pod -c test #如果一个pod中有多个容器就需要用-c来指定容器名称

kubectl get pod -o wide
    curl 10.244.2.8
