我已经建立了一个裸机k8集群（1个主节点-Raspberry pi上的intel NUC和2个工作节点）。我设法设置了Metal-lb负载平衡和Nginx入口控制器。我已经启动了两个应用程序，ghost（监听默认端口2368）和nextcloud（监听默认端口80）。我正在尝试从公用ip myhomeserver.io（访问幻影应用程序）和nextcloud.myhomeserver.io（访问下一个云应用程序）访问应用程序。我可以访问ghost应用程序，但似乎无法访问nextcloud。下面是用于入口和服务的yaml文件。不知道我要去哪里错了。

kubectl get services --all-namespaces
