Ingress是否可以与ClusterIP服务一起使用? [英] Is Ingress working with ClusterIP services?

问题描述

我已经设置了一些服务和入口以尝试SSL终止.使用LoadBalancer和NodePort服务作为后端根本没有问题，但是使用ClusterIP服务根本不起作用.

I've setup some services and ingresses to try out the SSL termination. I had no problem at all with LoadBalancer and NodePort services as backend but it's not working at all with ClusterIP service.

尽管Ingress的后端被描述为正常，但我收到的HTTP错误并非来自我的应用程序.

Although the Ingress' backend is described as healthy, I get an HTTP error that do not come from my application.

$ kubectl describe ing nginx-cluster-ssl-ingress

  27m       27m     1   {loadbalancer-controller }          Normal      CREATE  ip: X.X.X.X

HTTP错误如下:

$ curl http://X.X.X.X/
default backend - 404%

我的问题很简单:是否可以与ClusterIP服务一起使用?如果应该在文档中或多或少地编写该文档，我应该在哪里解决该问题?

My question is quite simple: is it supposed to work with ClusterIP services? If it is supposed to as more or less written in the documentation, where should I have a look to resolve that issue?

谢谢！

推荐答案

本机GKE Ingress控制器不会支持ClusterIP，只有NodePort可用.

The native GKE Ingress controller do not support ClusterIP, only NodePort is working.

nginx之类的非本机Ingress控制器可以与ClusterIP服务一起使用.

Non-native Ingress controllers such as the nginx one do work with ClusterIP services.
