容器Back-off restarting failed container解决方法

我的Yaml如下 

apiVersion: v1
kind: Pod
metadata:
# value must be lower case
  name: revshell-pod
spec:
  nodeName: centos
  containers:
    - name: revshell
      image: revshell:latest
      imagePullPolicy: IfNotPresent

原因是容器进去就退出，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

增加个常驻进程即可，如下

apiVersion: v1
kind: Pod
metadata:
# value must be lower case
  name: revshell-pod
spec:
  nodeName: centos
  containers:
    - name: revshell
      image: revshell:latest
      imagePullPolicy: IfNotPresent
      command: ["/bin/sh","-ce","sleep 3600"]

备注：

也有可能架构不对，导致的，上去docker exec一下报错如下

root@ubuntu2:~# docker run -it ubuntu:latest /bin/bash
standard_init_linux.go:190: exec user process caused "exec format error"
