docker on ubuntu 16.04 OCI启动容器时出错
以下命令docker run -d ubuntu /dev/null将返回以下错误
docker: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \"/dev/null\": permission denied".
这是我的操作系统信息

你预计会发生什么？
你试图运行/dev/null作为一个没有任何意义的命令。 当然，试图执行一个字符设备会给你一个“权限被拒绝”的错误。
