网上找别人的镜像太麻烦有时候还不稳定，不如自建（用Cloudflare Workers）
部署代码：

<div>addEventListener("fetch", (event) => {</div>
<div> event.passThroughOnException();</div>
<div> event.respondWith(handleRequest(event.request));</div>
<div>});</div>
<div>const dockerHub = "https://registry-1.docker.io";</div>

<div><h3>带镜像仓库地址使用说明</h3><p>使用例子</p></div>
<div><pre><code># 拉取某个官方镜像（不带命名空间）</div>
<div>docker pull stilleshan/frpc:latest</div>
<div># 拉取 代理拉取镜像</div>
<div>docker pull hub.songwqs.top/stilleshan/frpc:latest</div>
<div># 重命名镜像</div>
<div>docker tag hub.songwqs.top/stilleshan/frpc:latest stilleshan/frpc:latest</div>
<div># 删除代理镜像</div>
<div>docker rmi hub.songwqs.top/stilleshan/frpc:latest</div>
<div></code></pre><h3>镜像源方式使用说明</h3><p>1.添加镜像源</p></div>
<div> <pre><code># 添加镜像代理到 Docker 镜像源</div>
<div>sudo tee /etc/docker/daemon.json << EOF</div>
<div>{</div>
<div> "registry-mirrors": ["https://hub.songwqs.top"]</div>
<div>}</div>
<div>EOF</code></pre><p>2.拉取镜像</p></div>
<div><pre><code># 拉取 redis 官方镜像</div>
<div>docker pull redis</div>
<div># 拉取 rabbitmq 非官方镜像</div>
<div>docker pull bitnami/rabbitmq</div>
<div># 拉取 postgresql 官方镜像</div>
<div>docker pull postgresql</code></pre></div>
