1.详细报错信息

• 执行docker exec -it [containerId] /bin/bash报错：

OCI runtime exec failed: exec failed: container_linux.go:349: 
starting container process caused "exec: \"/bin/bash\": stat
/bin/bash: no such file or directory": unknown

解释：说明镜像不包括bash风格的操作，提示未知的文件或目录。

2.解决

• 可以试下将/bin/bash 改成 /bin/sh
• 执行命令：docker exec -it [containerId] /bin/sh
  
  从上图看已经成功进入到了容器中
