Back-off restarting failed container

 command: [ "/bin/bash", "-c", "--" ]
 args: [ "while true; do sleep 30; done;" ]
     上面是命令下面是值，是key vlaue的格式
     这个的意思就是一直死循环的执行着进程，因为装的nginx没有成功安装

由于通过指定的镜像启动容器后，容器内部没有常驻进程，导致容器启动成功后即退出，从而进行了持续的重启。
可以看到container都创建好了，但是image镜像已经存在了，没有调起后面的进程，这时候只需要配合在后面创建个job或者创建一个
Job 负责批处理任务，即仅执行一次的任务，它保证批处理任务的一个或多个 Pod 成功结束
#configmap代替环境变量
apiVersion: v1
kind: Pod
metadata:
name: dapi-test-pod
spec:
containers:

• name: test-container
  image: hub.bosssoft.com/library/nginx:v1.8
  command: [ "/bin/sh", "-c", "env" ]
  env:
  • name: SPECIAL_LEVEL_KEY
    valueFrom:
    configMapKeyRef:
    name: special-config
    key: special.how
    • name: SPECIAL_TYPE_KEY
      valueFrom:
      configMapKeyRef:
      name: special-config
      key: special.type
      envFrom:
    • configMapRef:
      name: env-config
      restartPolicy: Never
      
      两种方法都可以
      kubectl apply -f myapp-deploy.yaml

kubectl get pod
