进入 docker 容器报错：OCI runtime exec failed: exec failed: unable to start container process: exec: "bash": executable file not found in $PATH: unknown

在进入测试站某容器时，默认执行 docker exec -it xxx /bin/bash 报错：

OCI runtime exec failed: exec failed: unable to start container process: exec: "bash": executable file not found in $PATH: unknown

查看了一下，服务器环境存在 /bin/bash。bing 了一下，原来是指容器的环境，建议使用 /bin/sh 替换。

尝试 docker exec -it xxx /bin/sh，成功！。
