saeipi@ayumi ~ % docker info|grep Root
Docker Root Dir: /host_mnt/Volumes/data/Docker/docker
查看 docker 存储位置
# sudo docker info | grep "Docker Root Dir"
Docker Root Dir: /var/lib/docker
停止 docker 服务
systemctl stop docker
复制目录内容，/data/lib/docker为修改后的 docker 存储位置
rsync -avzP /var/lib/docker/ /data/lib/docker
备份原目录
mv -u /var/lib/docker /var/lib/docker.bak
新存储位置符号链接到源路径
ln -s /data/lib/docker /var/lib/docker
重启 docker 服务
systemctl start docker
用systemctl status docker检查服务正常后，删除原目录备份
rm -rf /var/lib/docker.bak
cd ~/Library/Containers/com.docker.docker
mv ~/Library/Containers/com.docker.docker/Data /mnt/docker
# 然后建立一个软链接链接回来就可以了：
ln -s /mnt/docker/Data ~/Library/Containers/com.docker.docker/Data
