I have 2 services named A and B
I have pods a1,a2,a3 for Service A.
I have pods b1,b2,b3 for Service B.
Service A -> Type = ClusterIP
Service B -> Type= LoadBalancer
if I try to do nslookup from a1 -> b1 I am getting below error.
>kubectl exec a1 -- nslookup b1
nslookup: can't resolve '(null)': Name does not resolve
nslookup: can't resolve 'cassandra-0': Name does not resolve
command terminated with exit code 1please help me to find the issue and why it's not reachable from other pods
updated with actual info::
root-user> kubectl get services --all-namespaces -o wide

# in one terminal:
$ kubectl run -i -t --rm there --restart=Never --image=quay.io/mhausenblas/jump:0.2 -- sh
# in another terminal
$ kubectl describe pod there | grep IP

$ kubectl run -i -t --rm here --restart=Never --image=quay.io/mhausenblas/jump:0.2 -- sh
