# 编辑服务文件 sudo vi /lib/systemd/system/docker.service # 添加 --graph="/data/docker-images" ExecStart=/usr/bin/dockerd --graph="/data/docker-images" -H fd:// --containerd=/run/containerd/containerd.sock
重启服务
systemctl daemon-reload sudo systemctl restart docker
使用国内镜像服务器
vi /etc/docker/daemon.json # 添加以下内容（网易镜像仓库） { "registry-mirrors": [ "https://hub-mirror.c.163.com" ] }
测试
sudo docker pull ubuntu
查看镜像是否下载到/data/docker-images
sudo du -d 1 -h
结果如下：
4.0K ./swarm 4.0K ./tmp 4.0K ./trust 88K ./buildkit 40K ./network 72M ./overlay2 332K ./image 16K ./plugins 4.0K ./runtimes 4.0K ./containers 28K ./volumes 72M .
修改用户权限，docker指令不需要sudo
sudo gpasswd -a ubuntu docker sudo newgrp docker sudo systemctl restart docker
