【问题描述】：
我有一个运行基本前端 Angular 应用程序的 docker 容器。我已经验证它运行没有问题，并且我可以在浏览器中使用docker run -p 5901:80 formbuilder-stand-alone-form 成功访问 Web 应用程序。
我能够在我的云开发服务器上使用 minikube 和 kubernetes 成功部署它

stand-alone-service LoadBalancer 10.96.197.197 <pending> 5901:30443/TCP 21s
但是，我无法通过 url 访问它：
one@work ...github/stand-alone-form-builder-hhh/form-builder-hhh
% minikube service stand-alone-service
|-----------|---------------------|-------------|---------------------------|
| NAMESPACE | NAME | TARGET PORT | URL |
|-----------|---------------------|-------------|---------------------------|
| default | stand-alone-service | 5901 | http://192.168.49.2:30443 |
|-----------|---------------------|-------------|---------------------------|
在这个例子中，http://192.168.49.2:30443/ 给了我一个死网页。
我禁用了所有 iptables 以进行故障排除。
知道如何访问前端网络应用程序吗？我在想我可能把选择器弄错了，但可以肯定。
更新：这是请求的新输出：

注意：我注意到隧道现在确实有一个负载均衡器的外部 IP：

% kubectl get service

【问题讨论】：
-
服务接线看起来是正确的，但要仔细检查，你能
kubectl describe service stand-alone-service吗？特别是在最后你应该看到一行写着Endpoints:，它不应该说“无”。
