将Spring云网关路由迁移到Kubernetes入口路由

我目前正在使用SpringCloudGateway来处理我的路由，我正在努力找出如何在Kubernetes Ingress中创建重写规则。我的SpringGateway逻辑如下所示

当前Spring网关路由

spring:
  application:
    name: gateway-service
  cloud:
    gateway:
      routes:
        - id: clover-service
          uri: http://domain:9500
          predicates:
            - Path=/portal/api/clover/**
          filters:
              //Rewrite to http://domain:9500/api/clover
            - RewritePath=/portal(?<segment>/?.*), $\{segment} 
        - id: auth-svc
          uri: http://domain:8900
          predicates:
            - Path=/portal/auth/**
          filters:
              //Rewrite to http://domain:8900/auth
            - RewritePath=/portal/auth(?<segment>/?.*), $\{segment}

        ######################################################
        ##                                                  ##
        ##   The default goes to the nuxt frontend app      ##
        ##                                                  ##
        ######################################################

        - id: frontend
          uri: http://domain:3000
          predicates:
            - Path=/**

似乎重写目标正在重写我的所有路由，而不是单个路由。有人知道如何重写单独的路由吗？

看看Kubernetes中的定义

Kubernetes中的Official入口配置不支持此选项。但您可以使用支持spring注释的其他实现的入口网关。您可以在此处找到更多信息：

您的Ingress配置文件应该包括注释，如

kubernetes.io/Ingress.class:spring.cloud.gateway

和

spring.cloud.gateway/routes

以下是示例入口配置文件：

apiVersion: networking.k8s.io/v1beta1
 kind: Ingress
 metadata:
   name: httpbin
   namespace: ingress
   annotations:
     kubernetes.io/ingress.class: spring.cloud.gateway
     spring.cloud.gateway/routes: |
       predicates:
       - Host=httpbin.nlighten.nl
       - Path=/{segment}
       filters:
       - SetPath=/anything/{segment}
       - PreserveHostHeader
       - SecureHeaders
       - name: Retry
         args:
           retries: 3
           statuses: BAD_GATEWAY
       uri: lb://httpbin
 spec:
   backend:
     serviceName: httpbin
     servicePort: 80

记住在适当的名称空间中创建入口。网关和后端必须在同一命名空间中运行

apiVersion: networking.k8s.io/v1beta1
 kind: Ingress
 metadata:
   name: httpbin
   namespace: ingress
   annotations:
     kubernetes.io/ingress.class: spring.cloud.gateway
     spring.cloud.gateway/routes: |
       predicates:
       - Host=httpbin.nlighten.nl
       - Path=/{segment}
       filters:
       - SetPath=/anything/{segment}
       - PreserveHostHeader
       - SecureHeaders
       - name: Retry
         args:
           retries: 3
           statuses: BAD_GATEWAY
       uri: lb://httpbin
 spec:
   backend:
     serviceName: httpbin
     servicePort: 80
