Debugging DNS Resolution

Use that manifest to create a Pod

kubectl apply -f dnsutils-pod.yaml

…and verify its status

kubectl get pods dnsutils

Once that Pod is running, you can exec nslookup in that environment

kubectl exec -i -t dnsutils -- nslookup kubernetes.default

Finally remove the pod

kubectl delete -f dnsutils-pod.yaml
