Traefik Ingress Stripprefix

Question

使用Traefik作为入口控制器，并寻找一种剥离前缀的方法。由于这些前缀的路径部分将“转发”到服务上，除非服务也在同一路径上聆听，那么该服务将达到404。在文档中，如何删除转发路径，是否很清楚，有没有指针？

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: azure-vote-route
  namespace: azure-vote
spec:
  rules:
    - host: <>.<>.cloudapp.azure.com
      http:
        paths:
        # - path: /
        #   pathType: Prefix
        #   backend:
        #     service:
        #       name: azure-vote-front
        #       port:
        #         number: 80
        - path: /foo
          pathType: Prefix
          backend:
            service:
              name: azure-vote-front
              port:
                number: 80

选项1
善良：入口
并使用Traefik的中间件剥离前缀。并且使用入学定义上的注释来驳斥此中间件
＆lt; Middlewear的命名空间＆gt; - ＆lt; Middlewear的名称＆gt;

eg

apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: ingress-stripprefix
  namespace: azure-vote
spec:
  stripPrefix:
    prefixes:
      - /foo

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-a
  namespace: azure-vote
  annotations:
    traefik.ingress.kubernetes.io/router.middlewares: azure-vote-ingress-stripprefix@kubernetescrd
spec:
  rules:
    - host: <>.<>.cloudapp.azure.com
      http:
        paths:
          - path: /foo
            pathType: Prefix
            backend:
              service:
                name:  azure-vote-front
                port:
                  number: 80

选项2
类型：IngressRoute（这是Traefik特定的入口实现。）

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: ingressroute-middle
  namespace: azure-vote
spec:
  entryPoints:
    - web
  routes:
    - match: Host(`<>.cloudapp.azure.com`) && PathPrefix(`/test`)
      kind: Rule
      services:
        - name: azure-vote-front
          port: 80
      middlewares:
        - name: testmiddle
    - match: Host(`<>.cloudapp.azure.com`)
      kind: Rule
      services:
        - name: azure-vote-front
          port: 80
      middlewares:
        - name: testmiddle
---
apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: testmiddle
  namespace: azure-vote
spec:
  stripPrefix:
    prefixes:
      - /test
