为什么我的ISTIO策略配置未应用？

Question

我使用Istio-1.0.6来实现身份验证/授权。我试图使用Jason Web Tokens（JWT）。我按照文档中的大多数示例进行了操作，但是我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

        Port:

结果

我期待得到401错误，但我得到200.我的配置有什么问题，我该如何解决这个问题？

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

Answer 1

你有：

Port:              <unset>  8080/TCP

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

我试过Istio 1.1。我得到了503而不是401。
