进docker容器时报错“OCI runtime exec failed: exec failed: unable to start container process: exec: "bash": executable file not found in $PATH: unknown”

今天在准备进入容器时发现提示了“OCI runtime exec failed: exec failed: unable to start container process: exec: "bash": executable file not found in $PATH: unknown”

根据提示能看到缺少bash工具导致的，那就安装下bash工具吧
虚机为centOS，用yum install -y bash

安装后再次执行docker exec -it 容器id bash发现还是提示此错误，暂时还不知道原因，可以改用docker exec -it 容器id sh命令一样可以。

bash和sh命令区别：
