自建 CloudFare DockerHub 镜像加速站

 自建 CloudFare DockerHub 镜像加速站站点:dockerhub.openface.cc

测试效果:

测试设备:上海腾讯云服务器

测试环境:国内网络环境

拉取命令:docker pull dockerhub.openface.cc/homeassistant/home-assistant

在未进行优选ip的情况下,速度拉满🤭

教程实践准备:

Cloudfare账号
解析到Cloudfare的域名(可选)

步骤:
创建Cloudfare Workers


一直选下一步,选择编辑代码

    resHdrNew.delete('content-security-policy-report-only')
    resHdrNew.delete('clear-site-data')

    return new Response(res.body, {
        status,
        headers: resHdrNew
    })
}

将代码中的const workers_url = 'https://dockerhub.openface.cc' 更改为你自己的域名(可选),或者你可以查看此worker的网页链接域名进行更换,点击部署,就可以使用了。
