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

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