这是一个新装的docker环境,其中看不出当前docker文件存储的路径。但是docker默认会使用 /var/lib/docker 作为默认存储位置。
- 停止 Docker 服务
sudo /etc/init.d/docker stop
- 将原来默认的/var/lib/docker备份一下,然后复制到别的位置并建立一个软链接
cd /var/lib
sudo cp -rf docker docker.bak
sudo cp -rf docker /<my_new_location>/
sudo ln -s /<my_new_location>/docker docker
- 启动 Docker 服务
sudo /etc/init.d/docker start
- 最后使用 docker info 查看更新结果
sudo docker info
