我使用kubeadm创建了一个kubernetes集群。服务声明为ClusterIP。目前，我正试图部署我的应用程序作为类型loadbalancer与Metallb的入口，但我面临一些问题。如果我将应用部署为入口，则找不到一些jv和css组件。将应用程序作为服务运行没有问题，但在使用Ingress时出现了问题。它是一个ASP。. NET Core应用程序

如果我在浏览器中打开控制台，我可以看到<script>类型的所有元素上都有404 not found。
如果你仔细查看日志，你可以发现问题的原因是你的应用程序在路径tasty.taco.com/css/site.css中请求静态内容(例如css/site.css文件)，并且由于入口控制器在其定义中没有前缀/css的定义，它返回404错误代码。
静态内容在以下路径tasty.taco.com/web1/css/site.css中可用-注意，我使用了web1前缀，因此Ingress知道将此请求重定向到哪个服务。
一般来说，在请求静态内容的应用程序中使用注释nginx.ingress.kubernetes.io/rewrite-target经常会导致这样的问题。
修复不是在你的例子中，使用UsePathBaseMiddleware类来设置基础URL。
表示从请求路径中提取指定路径基并将其延迟到请求路径基的中间件。
关于详细步骤，我建议按照这个答案中给出的步骤操作。
