**docker默认位置/var/lib/docker**

以下是修改步骤：

**1.停止docker**

root@ubuntu:~# /etc/init.d/docker stop

2.迁移Docker路径

root@ubuntu:~# cd /var/lib/
    root@ubuntu:~# mv docker /media/sdj1/

3.建立软连接

ln -s /media/sdj1/docker docker

4.启动docker

root@ubuntu:~# /etc/init.d/docker start

5.docker info 再次查看信息

root@ubuntu:/var/lib/docker# docker info
