docker镜像源配置

docker默认的镜像源，走的是国外网络，下载速度感人，修改镜像源，进入/etc/docker/

cd /etc/docker

编辑文件daemon.json(没有就直接创建)，内容：

{"registry-mirrors": ["https://q7ta64ip.mirror.aliyuncs.com","https://hx983jf6.mirror.aliyuncs.com","https://docker.mirrors.ustc.edu.cn","https://hub-mirror.c.163.com","https://docker.m.daocloud.io","https://ghcr.io","https://mirror.baidubce.com","https://docker.nju.edu.cn"]
}

然后重启

systemctl daemon-reload
systemctl restart docker
