k8s创建alpine容器时出现Back-off restarting failed container问题

1、问题：k8s创建alpine容器时出现Back-off restarting failed container，容器一直进行重启。

2.原因：对于像ubuntu这样的系统级docker ，用k8s集群启动管理后，会自动关闭，解决方法就是 让其一直在运行，所以在yaml文件中增加command命令即可。

3.解决：在yaml中添加如下参数：

command: [ "/bin/bash", "-c", "--" ]
args: [ "while true; do sleep 30; done;" ]

ubuntu.yaml

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: ubuntu-deploy
spec:
  replicas: 1
  template:
    metadata:
      labels:
        name: ubuntu
    spec:
      containers:
        - name: ubuntu-tz
          command: ["/bin/bash","-c","--"]
          args: ["while true; do sleep 30; done;"]
          securityContext:
            privileged: true
          image: ubuntu:16.04

重新进行部署就可以了~~~
