I'm on a kubernetes cluster with 3 nodes that are all VM and they use to communicate a bridge that is an Only-Host interface:
192.168.99.101 master
192.168.99.102 and .103 the other nodes I have used to create the cluster kubeadm and I have passed this addiction paramethers_ --api-advertise-address=192.168.99.101

Now, if I use them in my application the IP of the services that connect me to a deploy it works fine, but if I try to use the name of the same services I can't find it(but I see that:

kubectl get svc -n kube-system
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kube-dns ClusterIP 10.96.0.10 <none> 53/UDP,53/TCP 57m

i use this guide to solve and i have find that errors but i don't knwo how to solve:

vmmaster@vmmaster-VirtualBox:~/Documenti/Tesi/NFS$ kubectl exec -ti busybox -- nslookup kubernetes.default
Server: 10.96.0.10
Address 1: 10.96.0.10

nslookup: can't resolve 'kubernetes.default'
command terminated with exit code 1

i have follow the next step, i copy only the things with logs W F and E because they are the erro logs:

 kubectl logs --namespace=kube-system $(kubectl get pods --namespace=kube-system -l k8s-app=kube-dns -o name) -c kubedns
