由于最近国内无法正常拉取docker镜像然而找了几个能用的docker镜像源发现拉取回来的docker镜像不是最新的版本部署到Cloudflare里Workers 和 Pages拉取docker 镜像成功故记录部署过程。 部署服务 登录Cloudflare后进入Workers 和 Pages再点击概述创建应用程序。 点击创建输入名称然后点击部署 部署成功点击编辑代码 粘贴下列代码
use strict
const hub_host registry-1.docker.io
const auth_url https://auth.docker.io
const workers_url https://xxx自己的域名
const PREFLIGHT_INIT {status: 204,headers: new Headers({access-control-allow-origin: *,access-control-allow-methods: GET,POST,PUT,PATCH,TRACE,DELETE,HEAD,OPTIONS,access-control-max-age: 1728000,}),
}
function makeRes(body, status 200, headers {}) {headers[access-control-allow-origin] *return new Response(body, {status, headers})
}
function newUrl(urlStr) {try {return new URL(urlStr)} catch (err) {return null}
}
addEventListener(fetch, e {const ret fetchHandler(e).catch(err makeRes(cfworker error:\n err.stack, 502))e.respondWith(ret)
})
async function fetchHandler(e) {const getReqHeader (key) e.request.headers.get(key);let url new URL(e.request.url);if (url.pathname /token) {let token_parameter {headers: {Host: auth.docker.io,User-Agent: getReqHeader(User-Agent),Accept: getReqHeader(Accept),Accept-Language: getReqHeader(Accept-Language),Accept-Encoding: getReqHeader(Accept-Encoding),Connection: keep-alive,Cache-Control: max-age0}};let token_url auth_url url.pathname url.searchreturn fetch(new Request(token_url, e.request), token_parameter)}url.hostname hub_host;let parameter {headers: {Host: hub_host,User-Agent: getReqHeader(User-Agent),Accept: getReqHeader(Accept),Accept-Language: getReqHeader(Accept-Language),Accept-Encoding: getReqHeader(Accept-Encoding),Connection: keep-alive,Cache-Control: max-age0},cacheTtl: 3600};if (e.request.headers.has(Authorization)) {parameter.headers.Authorization getReqHeader(Authorization);}let original_response await fetch(new Request(url, e.request), parameter)let original_response_clone original_response.clone();let original_text original_response_clone.body;let response_headers original_response.headers;let new_response_headers new Headers(response_headers);let status original_response.status;if (new_response_headers.get(Www-Authenticate)) {let auth new_response_headers.get(Www-Authenticate);let re new RegExp(auth_url, g);new_response_headers.set(Www-Authenticate, response_headers.get(Www-Authenticate).replace(re, workers_url));}if (new_response_headers.get(Location)) {return httpHandler(e.request, new_response_headers.get(Location))}let response new Response(original_text, {status,headers: new_response_headers})return response;
}

}修改域名然后点击部署 点击设置触发器然后添加路由 设置路由选择域名区域 解析DNS添加A记录名称为域名前缀IPV48.8.8.8即可(这里可以随便填写) 最后配置镜像源验证拉取镜像 #编辑/etc/docker/daemon.json 文件配置过是不存在,就新建个
sudo vim /etc/docker/daemon.json
#写入文件内容
{ registry-mirrors:[https://xxx.域名.com]
}
#保存退出
wq!#重启docker 服务
sudo service docker restart#验证docker 是否生效
sudo docker info|grep Mirrors -A 1#查看打印结果
拉取镜像
