从kubernetes吊舱开放端口获取连接被拒绝

我是kubernetes的新手，我正在尝试将一个带有Gitlab管道的MEAN stack应用程序部署到Google云中的kubernetes引擎。然而，我就是无法让它让我连接到一个在开放端口4200上运行代码的pod。你可以在下面找到我的YAML配置。 Dockerfile

Gitlab-ci.yml

docker-compose-stack.yml

运行kubectl get svc-all namespaces可以获得以下输出：

有什么想法吗？谢谢。

您的应用程序正在本地主机上侦听，而负载平衡器将流量转发到以太网网络接口

您需要更改应用程序并使其在0.0.0.0上运行。

这确实有效。非常感谢，我花了一整天的时间才搞定！很高兴它起到了作用。这确实有效。非常感谢，我花了一整天的时间才搞定！很高兴这有帮助。
