自建 docker 代理一些方法参考(备忘供各位使用)

我这里附加上Cloudflare反向代理设置方法: 优点：只需有CF账号就行，自己专属，不用自己签发证书 缺点：CF在国内有DNS污染，可能无法正常访问

简要步骤： 1，登录到CF https://dash.cloudflare.com/ 2，控制台面板 -> 左侧 Workers 和 Pages  ->  创建应用程序  -> 创建 Worker ->  点击保存 -> 点击完成 -> 编辑代码

import HTML from './docker.html';
export default {
  async fetch(request) {
    const url = new URL(request.url);
    const path = url.pathname;
    const originalHost = request.headers.get("host");
    const registryHost = "registry-1.docker.io";
    if (path.startsWith("/v2/")) {
      const headers = new Headers(request.headers);
      headers.set("host", registryHost);
      const registryUrl = `https://${registryHost}${path}`;
      const registryRequest = new Request(registryUrl, {
        method: request.method,
        headers: headers,
        body: request.body,
        redirect: "follow",
      });
      const registryResponse = await fetch(registryRequest);
      console.log(registryResponse.status);
      const responseHeaders = new Headers(registryResponse.headers);
      responseHeaders.set("access-control-allow-origin", originalHost);
      responseHeaders.set("access-control-allow-headers", "Authorization");
      return new Response(registryResponse.body, {
        status: registryResponse.status,
        statusText: registryResponse.statusText,
        headers: responseHeaders,
      });
    } else {
      return new Response(HTML.replace(/{{host}}/g, originalHost), {
        status: 200,
        headers: {
          "content-type": "text/html"
        }
      });
    }
  }
}
