无法访问网络上的 Web 应用运行 kubernetes 和 minikube

Question

我有一个 docker 容器，它运行一个基本的前端 angular 应用程序。我已经验证它运行没有问题，我可以使用 docker run -p 5901:80 formbuilder-stand-alone-form.

在浏览器中成功访问网络应用程序

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 Web 应用程序吗？我在想我可能选错了选择器，但确实如此。

更新：这是请求的新输出：

注意：我注意到隧道我现在确实有一个用于负载均衡器的外部 IP：

one@work ...github/stand-alone-form-builder-hhh/form-builder-hhh (main)
% kubectl get service   
NAME                  TYPE           CLUSTER-IP      EXTERNAL-IP     PORT(S)          AGE

Answer 1

您的 LoadBalancer 似乎没有完全正确解析，因为外部 IP 仍标记为 <pending>

根据 Minikube 的说法，当隧道丢失时会发生这种情况： https://minikube.sigs.k8s.io/docs/handbook/accessing/#check-external-ip

您是否在单独的命令中尝试过运行 minikube tunnel window？
