为什么我的 ISTIO 策略配置没有应用？

Question

我正在使用 Istio-1.0.6 来实现身份验证/授权。我正在尝试使用 Jason Web Tokens (JWT)。我遵循了文档中的大多数示例，但没有得到预期的结果。这是我的设置：

服务

kubectl describe services hello
Name:              hello
Namespace:         agud
Selector:          app=hello
Type:              ClusterIP
IP:                10.247.173.177
Port:              <unset>  8080/TCP
TargetPort:        8080/TCP
Endpoints:         172.16.0.193:8080
Session Affinity:  None

网关

kubectl describe gateway

Kind:         Gateway

  Cluster Name:

虚拟服务

    Route:
      Destination:
        Host:  hello.agud.svc.cluster.local
        Port:
          Number:  8080

政策

kubectl describe policies
Name:         jwt-hello
Namespace:    agud
API Version:  authentication.istio.io/v1alpha1
Kind:         Policy

  Cluster Name:

  UID:                 cf9ed2aa-4951-11e9-9f64-fa163e804eca
Spec:
  Origins:
    Jwt:
      Audiences:
        hello
      Issuer:         testing@secure.istio.io
      Jwks Uri:       https://raw.githubusercontent.com/istio/istio/release-1.0/security/tools/jwt/samples/jwks.json
  Principal Binding:  USE_ORIGIN
  Targets:
    Name:  hello.agud.svc.cluster.local

结果

我预计会收到 401 错误，但我收到了 200。我的配置有什么问题，如何解决？

curl $INGRESS_HOST/hello -s -o /dev/null -w "%{http_code}\n"
200

Answer 1

你有：

Port:              <unset>  8080/TCP

对于Istio 路由和安全，您必须将端口名称设置为http 或http-<something>。

我尝试使用 Istio 1.1。我得到的是 503 而不是 401。
