Wait for applications ready:

kubectl wait --for=condition=ready --timeout=1m pod -l app=alpine -n ns-select-forwarder

kubectl wait --for=condition=ready --timeout=1m pod -l app=nse-kernel -n ns-select-forwarder

Ping from NSC to NSE:

kubectl exec pods/alpine -n ns-select-forwarder -- ping -c 4 169.254.0.0

Ping from NSE to NSC:

kubectl exec deployments/nse-kernel -n ns-select-forwarder -- ping -c 4 169.254.0.1
