kubernetes - Ingress 无法在谷歌 kubernetes 引擎中用于多项服务(Spring Boot)

Question

我在谷歌云的集群中部署了两个服务。

当我运行:kubectl get services 我得到->

NAME           TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)          AGE
hello-java-1   NodePort    10.7.254.204   <none>        8080:31848/TCP   21m
hello-java-2   NodePort    10.7.246.52    <none>        8080:30624/TCP   19m
kubernetes     ClusterIP   10.7.240.1     <none>        443/TCP          23m

现在，我按照谷歌云文档进行了跟踪:Ingress并将扇出入口配置为:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: fanout-ingress
spec:
  rules:
  - http:
      paths:
      - path: /product/*
        backend:
          serviceName: hello-java-1
          servicePort: 8080
      - path: /list/*
        backend:
          serviceName: hello-java-2
          servicePort: 8080

现在:

$kubectl get ingress fanout-ingress
NAME             HOSTS     ADDRESS         PORTS     AGE
fanout-ingress   *         35.190.55.204   80        17m

我得到了这些结果。

我检查了命令:kubectl describe ingress fanout-ingress

输出是:

  *
        /product/*   hello-java-1:8080 (<none>)
        /list/*      hello-java-2:8080 (<none>)

  Normal  Service  8m (x4 over 17m)  loadbalancer-controller  no user specified default backend, using system default

现在，当我访问 http://35.190.55.204/product/home 时，出现了 spring whitelabel 错误。但是\home 是在应用程序中定义的!为什么会这样？

Answer 1

我明白了!对于/product/*路径，我们第一个服务的所有URL映射 spring应用中的Requestpath应该以/product/开头/p>

ex: /product/list, /product/add, /product/delete etc

对于 Ingress 路径规则/list/*，我们第二个服务中的所有 URL 映射 spring 应用程序中的 Requestpath 应该以 /list/ 开头

ex: /list/sort, /list/add, /list/delete etc
