kubernetes - Kubernetes Ingress - 仅将子路径传递给后端，而不是完整路径

问题描述

我想要一个 Ingress，它将host.com/abc/xyz路由到 service/xyz。我有以下配置，但它的路由 host.com/abc/xyz到 service/abc/xyz。

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    appgw.ingress.kubernetes.io/connection-draining: "true"
    appgw.ingress.kubernetes.io/connection-draining-timeout: "30"
    appgw.ingress.kubernetes.io/request-timeout: "300"
    appgw.ingress.kubernetes.io/health-probe-status-codes: "200-399, 401"
    kubernetes.io/ingress.class: azure/application-gateway
  generation: 1
  name: serviceAingress
  namespace: pantry-services
spec:
  rules:
  - host: myhost.net
    http:
      paths:
      - backend:
          serviceName: serviceA
          servicePort: 8083
        path: /abc/*
        pathType: Prefix
      - backend:
          serviceName: serviceA
          servicePort: 8083
        path: /abc
        pathType: Prefix

如何将 myhost.net/abc/* 路由到 service/* ？abc 不应包含在后端调用中。我也尝试过 pathType 作为 ImplementationSpecific

解决方案

我使用此处描述的后端路径前缀注释解决了这个问题 - https://github.com/Azure/application-gateway-kubernetes-ingress/blob/master/docs/annotations.md#backend-path-prefix
