Make sure all firewalls are open? I just tested it and it works:
``` $ kubectl run udp --image=ubuntu -- bash -c "while true; do sleep 100000; done" deployment "udp" created $ kubectl expose deployment udp --port=12345 --protocol=UDP --type=LoadBalancer service "udp" exposed ``` Then I got the IP from `get svc`. I used `kubectl exec -ti` to exec into my pod and run `nc -l -p 12345 -u` in one terminal and I sent bytes to it via `netcat -u <public ip> 12345`.
