通过Ingress-Gateway暴露kiali

若需要在集群外部访问Kiali,可通过为其定义相应的Gateway、VirtualService和DestinationRule资源完成。

FIELDS:
   apiVersion	<string>
     APIVersion defines the versioned schema of this representation of an

     https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

   kind	<string>
     Kind is a string value representing the REST resource this object
     represents. Servers may infer this from the endpoint the client submits
     requests to. Cannot be updated. In CamelCase. More info:
     https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
