输入uname –a 回车，用 uname 命令能够看到 NAS 的 CPU 架构、指令集等内容如下：

Linux DSM 3.10.105 #23739 SMP Fri Jun 8 12:51:05 CST 2018 x86_64 GNU/Linux synology_braswell_216+II

使用命令 docker info 查看docker详细信息，

如果提示 Cannot connect to the Docker daemon. Is the docker daemon running on this host? 说明当前的账号没有 root 权限，可以使用 sudo 提权来操作，或者可以通过切换到 root 账户下来操作，这里我们选择后者。

通过 admin 账号登录后，执行 sudo su - 切换到 root 账户下(注意这一步输入的是admin账号的密码)：docker详细信息如下：
