Spring boot 负载平衡器类型的Kubernetes入口未按预期工作

我安装在kubernetes集群中。当我试图通过入口控制器访问微服务端时，它没有按预期工作

我正在AWS实例上部署，我遵循了

我有两个Spring boot应用程序，其上下文路径为运行在端口9000上的/customer，运行在端口8000上的/prac，第三个是运行在端口80上的nginx

我已经执行了这些命令来创建LoadBalancer类型的入口控制器

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.30.0/deploy/static/mandatory.yaml

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.30.0/deploy/static/provider/aws/service-l4.yaml
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.30.0/deploy/static/provider/aws/patch-configmap-l4.yaml

我创建了经典的负载平衡器，但是负载平衡器的健康检查没有通过，健康检查我指向端口80，但是它显示为停止服务

我试图用集群IP进行检查，但它显示服务器的空响应，请帮助我

您是手动创建经典负载平衡器的吗？@ArghyaSadhu是的，我是手动创建的，并且我在ingress Nginx中设置了外部IP您不应该手动创建它…您应用的第二个yaml应该创建它automatically@ArghyaSadhu此static/provider/aws/service-l4.yaml本应创建它，但未创建它。现在需要做什么？好的，让我们开始手动…您是否创建了进出安全组？是否已将节点端口配置为LB中的实例端口？
