我是 k8s/minikube 的新手（某种程度上，也熟悉 unix 网络），所以如果我问了一些似乎没有意义的问题，我会很乐意澄清！
目标
我想要配置基于端口的 TCP 入口，如nginx-ingress 文档。特别是我想使用webpack-dev-server来自内部的minikube。
错误
当按照我的最佳理解进行设置时，我Failed to load resource: net::ERR_CONNECTION_REFUSED在请求时仍然会得到结果local.web:3001/client.js。也就是说，在浏览器中导航到“local.web/”会显示页面，但没有要webpack生成的包。该请求失败。
配置
从主机迁移到 minikube pod，我已经
在 /etc/hosts 中：
在我的开发机器上，我设置local.web为 minikube IP
$ echo "$(minikube ip) local.web" | sudo tee -a /etc/hosts

假设
一个想法是 TCP 服务上的命名空间ConfigMap错误。从文档中我不清楚它应该放在哪里。我已在命名空间中尝试过dev，其中有入口、服务和部署/pod。我还尝试将data上述条目添加到tcp-services ConfigMapin 中kube-system。
webpack pod 的日志没有显示任何错误，所以我不相信问题出在应用程序层面。
由于GET local.web/正在从 pod 返回数据，我确信该服务至少是部分正确的。
我愿意执行您建议的任何调试，并且不幻想我知道正在发生的事情——我会感激您提供的任何帮助。
