入口后端路径的句柄是否不正确?

我试图通过istio入口路由我的微服务,配置如下:

    apiVersion: extensions/v1beta1
    kind: Ingress
    metadata:
      name: test
      annotations:
        kubernetes.io/ingress.class: "istio"
    spec:
      rules:
      - http:
          paths:
          - path: /internal/v1.0/service
            backend:
              serviceName: sleep
              servicePort: 80
          - path: /external/v1.0/service
            backend:
              serviceName: sleep
              servicePort: 80

当我测试这个配置时,从集群得到404响应。 看来istio威胁到了我作为正则表达式的路径

    → istioctl -n istio-shop get ingress-rule test-1-1
    destination: sleep.istio-shop.svc.cluster.local
    match:
      httpHeaders:
        uri:
          regex: /internal/v1.0/service
    route:
    - tags:
        servicePortNum: "80"
        tlsSecret: ""

我找到的唯一解决办法就是摆脱”在服务API版本中,并使用以下内容:

- path: /internal/v1/service

结果:

    → istioctl -n istio-shop get ingress-rule test-1-3
    destination: sleep.istio-shop.svc.cluster.local
    match:
      httpHeaders:
        uri:
          exact: /external/v1/service
    route:
    - tags:
        servicePortNum: "80"
        tlsSecret: ""

和

    - path: /internal/v1.*

结果:

        → istioctl -n istio-shop get ingress-rule test-1-4
        destination: sleep.istio-shop.svc.cluster.local
        match:
          httpHeaders:
            uri:
              prefix: /external/v1
        route:
        - tags:
            servicePortNum: "80"
            tlsSecret: ""

我猜是“点”作为正则表达式部分处理,而不是常规符号。

这是一个bug吗?因为“/internal/v1.0/service”不是正则表达式
