Virtual service not working service entry yes

Networking

Hi,

I’m having an issue regarding the internal routing of my services. If I define the following virtualService and call it from another namespace does not work.

 apiVersion: networking.istio.io/v1alpha3
 kind: VirtualService
 metadata:
   annotations:
     meta.helm.sh/release-name: my-svc
     meta.helm.sh/release-namespace: service
   labels:
     app: my-svc
     app.kubernetes.io/instance: my-svc
     app.kubernetes.io/managed-by: Helm
     app.kubernetes.io/name: my-svc
     app.kubernetes.io/version: 0.0.0
   name: my-svc
   namespace: service
 spec:
   hosts:
     - my-svc
   http:
     - name: default
       route:
         - destination:
             host: my-svc

Instead of that if I define the following serviceEntry it works:

 apiVersion: networking.istio.io/v1alpha3
 kind: ServiceEntry
 metadata:
   annotations:
     meta.helm.sh/release-name: my-svc
     meta.helm.sh/release-namespace: service
   labels:
     app: my-service
     app.kubernetes.io/instance: my-svc
     app.kubernetes.io/managed-by: Helm
     app.kubernetes.io/name: my-svc
     app.kubernetes.io/version: 0.0.0
   name: my-svc
   namespace: service
 spec:
  endpoints:
    - address: my-svc.service.cluster.local
  hosts:
    - my-svc
  ports:
    - name: http
      number: 80
      protocol: HTTP
  resolution: DNS

What I’m doing wrong?
Thanks
