Examples how to expose k8s services =================================== Exposing dashboard via frontend and externalIPs ----------------------------------------------- * Edit `kubernetes-dashboard.yaml` and update `externalIPs` to the list of external IPs of your k8s minions * Run: ```bash kubectl create -f kubernetes-dashboard.yaml --namespace=kube-system ``` * Access: ```bash curl $ANY_MINION_EXTERNAL_IP:9090 ``` 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 9090 -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. * Access: ```bash curl 10.210.0.12:9090 ```
