我有三个需要通过 istio 入口网关公开的服务，我已经将这些服务的 dns 记录设置为指向入口网关负载均衡器，但我没有成功使其工作。

网关和虚拟服务配置文件：

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: test-gateway
spec:
  selector:
    istio: ingressgateway # use istio default controller
  servers:
  - port:
      number: 80
      name: http
      protocol: HTTP
    hosts:
    - "*.mywebsite.io"

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: virtualservice
spec:
  hosts:
  - "*.mywebsite.io"
  gateways:
  - test-gateway
  http:
  - name: "api-gateway"
    match:
    - uri:
        exact: "gateway.mywebsite.io"
    route:
      - destination:
           host: gateway.default.svc.cluster.local
           port:
             number: 8080
  - name: "visitor-service"
    match:
    - uri:
        exact: "visitor-service.mywebsite.io"
    route:
      - destination:
           host: visitor-service.default.svc.cluster.local
           port:
             number: 8000
  - name: "auth-service"
    match:
    - uri:
        exact: "auth-service.mywebsite.io"
    route:
      - destination:
           host: auth-service.default.svc.cluster.local
           port:
             number: 3004

我猜HttpMatchRequest的 URI 部分不能这样工作。尝试为每个子域添加 VirtualServices，即类似的东西。

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: gateway-virtualservice
spec:
  hosts:
  - "gateway.mywebsite.io"
  gateways:
  - test-gateway
  http:
  - name: "api-gateway"
    match:
    - uri:
        exact: "/" #or prefix
    route:
      - destination:
           host: gateway.default.svc.cluster.local
           port:
             number: 8080
