Docker pull鏡像速度慢解決方案

vim /etc/docker/daemon.json

追加以下國內鏡像地址：

{
    "registry-mirrors":[
        "https://docker.mirrors.ustc.edu.cn",
        "http://hub-mirror.c.163.com",
        "https://ajjpps56.mirror.aliyuncs.com"
    ]
}

再刷新配置重啟Docker

sudo systemctl daemon-reload
sudo systemctl restart docker

參考阿里云鏡像加速器配置：https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors
