Docker可用国内加速镜像地址分享

ubuntu系统，修改/etc/docker/daemon.json，修改如下。

{
    builder: {
        gc: {
            defaultKeepStorage: 20GB,
            enabled: true
        }
    },
    experimental: false,
    features: {
        buildkit: true
    },
    registry-mirrors: [
        "https://docker.mirrors.ustc.edu.cn",
        "https://mirror.baidubce.com",
        "https://docker.m.daocloud.io",
        "https://mirror.ccs.tencentyun.com",
        "https://docker.nju.edu.cn",
        "https://docker.mirrors.sjtug.sjtu.edu.cn",
        "https://mirror.gcr.io", 
        "https://docker.registry.cyou",
        "https://docker-cf.registry.cyou",
        "https://dockercf.jsdelivr.fyi",
        "https://docker.jsdelivr.fyi",
        "https://dockertest.jsdelivr.fyi",
        "https://mirror.aliyuncs.com",
        "https://dockerproxy.com 
    ]
}

【修改后需要重启】：

sudo systemctl daemon-reload
sudo systemctl restart docker
sudo systemctl status docker
sudo docker info
