I have a pod that need to contact an external HTTPS service.
The pod can resolved the IP of the external HTTPS service.
So without istio injected in the namespace my pod can connect to the external service.
If i enable the injection of istio in the namespace my pod can’t connect to the extenal service: i need to create a ServiceEntry so it can work normally.
Why do i need a ServiceEntry even if the external service can be resolved by DNS ?
