为什么我执行cmd 'kubectl get pods'，荚状态是'NotReady'？这是不合理的，这种状态属于节点状态

Question

参考文献：https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/

但是cmd的结果是(pod:双容器状态是NotReady )：

[root@devnet-master ~]# kubectl get pods
NAME                             READY   STATUS     RESTARTS   AGE
busybox-1                        1/1     Running    1          33d
local-volume-provisioner-k49c7   1/1     Running    0          29m
nginx                            2/2     Running    1          21m
two-containers                   1/2     NotReady   0          61m

版本如下：

[root@devnet-master ~]# kubectl version

描述pod的结果是：exec描述pod结果图像

应用yaml is：应用yaml图像

apiVersion: v1
kind: Pod
metadata:
  name: two-containers
spec:
  restartPolicy: Never
  volumes:
  - name: shared-data
    hostPath:      
      path: /data
  containers:
  - name: nginx-container
    image: xxxxxx/nginx:1.0
    volumeMounts:
    - name: shared-data
      mountPath: /usr/share/nginx/html
  - name: debian-container
    image: xxxxxx/debian:stable
    volumeMounts:
    - name: shared-data
      mountPath: /pod-data
    command: ["/bin/sh"]
    args: ["-c", "echo Hello from the debian container > /pod-data/index.html"]

• pod正在显示在就绪状态，因为根据屏幕截图，您已经提供了一个多容器吊舱。第二个容器naemd“”处于“已完成”状态，因为它只需执行一个echo命令。我怀疑您已经将restartPolicy设置为Onfailure，否则不会重新启动吊舱。但舱内的一个容器处于运行状态，而另一个则不是。因此，pod状态在"NotReady“中。
• kubectl get pods中“就绪”列下的"1/2“也表示只有两个容器处于就绪状态。
