最近 Docker Hub 被禁一事引起了不小的波动在这里简单讲下在这之后应该如何访问公开的 Docker Hub。
2. Cloudflare
2.1 搭建
搭建的前提是有一个在 Cloudflare 中被管理的域名此处不展开介绍在这里假设这个域名是 your-domain.com。
2.1.1 创建 Worker
点击页面左侧的 Workers Pages创建一个 Worker填入以下内容。请注意将 your-domain.com 替换为你自己的域名。
use strictconst hub_host registry-1.docker.io
const auth_url https://auth.docker.io
const workers_url https://your-domain.com
/*** static files (404.html, sw.js, conf.js)*//** type {RequestInit} */
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,}),
}/*** param {any} body* param {number} status* param {Objectstring, string} headers*/
function makeRes(body, status 200, headers {}) {headers[access-control-allow-origin] *return new Response(body, {status, headers})
}/*** param {string} urlStr*/
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)
})/*** param {FetchEvent} e*/
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))}return new Response(original_text, {status,headers: new_response_headers})
}/*** param {Request} req* param {string} pathname*/
function httpHandler(req, pathname) {const reqHdrRaw req.headers// preflightif (req.method OPTIONS reqHdrRaw.has(access-control-request-headers)) {return new Response(null, PREFLIGHT_INIT)}let rawLen const reqHdrNew new Headers(reqHdrRaw)const refer reqHdrNew.get(referer)let urlStr pathnameconst urlObj newUrl(urlStr)/** type {RequestInit} */const reqInit {method: req.method,headers: reqHdrNew,redirect: follow,body: req.body}return proxy(urlObj, reqInit, rawLen, 0)
}/**** param {URL} urlObj* param {RequestInit} reqInit*/
async function proxy(urlObj, reqInit, rawLen) {const res await fetch(urlObj.href, reqInit)const resHdrOld res.headersconst resHdrNew new Headers(resHdrOld)// verifyif (rawLen) {const newLen resHdrOld.get(content-length) || const badLen (rawLen ! newLen)if (badLen) {return makeRes(res.body, 400, {--error: bad len: ${newLen}, except: ${rawLen},access-control-expose-headers: --error,})}}const status res.statusresHdrNew.set(access-control-expose-headers, *)resHdrNew.set(access-control-allow-origin, *)resHdrNew.set(Cache-Control, max-age1500)resHdrNew.delete(content-security-policy)resHdrNew.delete(content-security-policy-report-only)resHdrNew.delete(clear-site-data)return new Response(res.body, {status,headers: resHdrNew})
}2.1.2 添加域名
进入创建好的 Worker 的配置页面在 Settings Tab 中选择 Triggers点击 Add Custom Domain添加 your-domain.com。
2.2 使用
2.2.1 配置为镜像
在 /etc/docker/daemon.json 加入以下内容
{registry-mirrors: [https://your-domain.com]
}然后重启 dockersystemctl restart docker
随后就能像往常一样直接 pull 了
docker pull busybox:latest
docker pull mysql/mysql-server:latest2.2.2 直接使用
docker pull your-domain.com/library/busybox:latest
docker pull your-domain.com/mysql/mysql-server:latest3. 使用 registry 首先你需要一个能正常访问 Docker Hub 的机器并在那台机器上正常安装 Docker。
3.1 搭建
找一个文件夹编辑 compose.yml 文件填入以下内容
services:registry:image: registry:2ports:- 5000:5000environment:REGISTRY_PROXY_REMOTEURL: https://registry-1.docker.io # 上游源REGISTRY_STORAGE_CACHE_BLOBDESCRIPTOR: inmemory # 内存缓存去掉本行以直接使用硬盘volumes:- ./data:/var/lib/registry然后执行 docker compose up -d 即可。
3.2 使用
使用方法同上。
