Exposing dashboard via frontend and externalIPs
-----------------------------------------------

Exposing dashboard via nodePort
-------------------------------
* Get nodePort of the service:
```bash
echo $(kubectl --namespace=kube-system get svc/kubernetes-dashboard -o go-template='{{(index .spec.ports 0).nodePort}}')
```
* NAT on your router/jump-box to any k8s minion public IP and nodePort to provide external access:
```bash
iptables -t nat -I PREROUTING -p tcp --dport 2080 -j DNAT --to-destination 10.210.0.12:32005
iptables -t nat -I POSTROUTING -d 10.210.0.12 ! -s 10.210.0.0/24 -j MASQUERADE
iptables -I FORWARD -d 10.210.0.12 -j ACCEPT
```
Where `10.210.0.12` is public IP of one of your k8s minions and `32005` is nodePort of `kubernetes-dashboard` service.
