忽略 EnvoyFilter 中的路由

如何解决忽略 EnvoyFilter 中的路由

我试图忽略 EnvoyFilter 中的某个路由，但不知道如何以及在何处将该逻辑添加到我的 yaml 文件中。不应将被忽略的路由移交给 ext_authz 身份验证服务。

apiVersion: networking.istio.io/v1alpha3
kind: EnvoyFilter
metadata:
  name: ext-authz
  namespace: istio-system
spec:
  configPatches:
    - applyTo: LISTENER
      ListenerMatch: 0.0.0.0_80
      patch:
        operation: MERGE
        value:
          per_connection_buffer_limit_bytes: 100000000 #100MB
    - applyTo: HTTP_FILTER
      match:
        context: SIDECAR_INBOUND
        listener:
          filterChain:
            filter:
              name: "envoy.filters.network.http_connection_manager"
              subFilter:
                name: "envoy.filters.http.router"
      patch:
        operation: INSERT_BEFORE
        value:
          name: envoy.ext_authz
          typed_config:
            '@type': type.googleapis.com/envoy.extensions.filters.http.ext_authz.v3.ExtAuthz
            transport_api_version: V3
            with_request_body:
              max_request_bytes: 100000000
              allow_partial_message: true
            grpc_service:
              # NOTE(tsandall): when this was tested with the envoy_grpc client the gRPC
              # server was receiving check requests over HTTP 1.1. The gRPC server in
              # OPA-Istio would immediately close the connection and log that a bogus
              # preamble was sent by the client (it expected HTTP 2). Switching to the
              # google_grpc client resolved this issue.
              google_grpc:
                target_uri: 127.0.0.1:9191
                stat_prefix: "ext_authz"
                per_stream_buffer_limit_bytes: 100000000
