kube-dns not resolving external urls with missing endpoints

Question

I am trying to find out why my kube-dns does not resolve external urls and it seems it is caused by missing endpoints as described in:

(I am using Google Kubernetes engine and the cluster was created with the Google Cloud console.)

https://kubernetes.io/docs/tasks/administer-cluster/dns-debugging-resolution/ (section Are DNS endpoints exposed)

I can see that the endpoints are not exposed which probably cause my issue.

However, the documentation here is not very clear:

If you do not see the endpoints, see the endpoints section in the debugging Services documentation.

I tried to study it and I am not sure about following:

1. Why the endpoints were not created automatically? We have kube-dns working in a different cluster and the endpoints exist there by default.
2. Do I need to add the endpoints manually or can I recreate the whole kube-dns service with these endpoints?
3. When adding manually, how do I choose the IP adresses to be correct?
4. Do I need to tell other kubernetes services to use these endpoints?

This is the service definition:
