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
