我们习惯的使用下面命令进入容器：

docker run -it --name container5 busybox /bin/bash

　　但是今天遇到报错如下：

[root@moapp-0003 ~]# docker exec -it c713b93718e0 /bin/bash
OCI runtime exec failed: exec failed: container_linux.go:380: starting container process caused: 
exec: "/bin/bash": stat /bin/bash: no such file or directory: unknown

　　核心信息就是：exec: "/bin/bash": stat /bin/bash: no such file or directory: unknown

　　解决方式：可以将上面的命令修改为

# 将/bin/bash修改为/bin/sh
docker run -it --name container5 busybox /bin/sh

[root@moapp-0003 ~]# docker exec -it c713b93718e0 /bin/sh
/data #
/data #

# 改成 /bin/sh 就可以了
