Is there anyway to get the external ports of the kubernetes cluster

I have exposed a service on an external port on all nodes in a kubernetes cluster from:

kubectl create -f nginx-service.yaml

You have exposed your service on an external port on all nodes in your cluster. If you want to expose this service to the external internet, you may need to set up firewall rules for the service port(s) (tcp:30002) to serve traffic.

See http://releases.k8s.io/release-1.2/docs/user-guide/services-firewalls.md for more details. service "nginx-service" created.`

How do I check if ports are open in Kubernetes pods?

shell into the pod and try running netstat -tulpn gives you all the ports open.

kubectl get svc --all-namespaces -o go-template='{{range .items}}{{range.spec.ports}}{{if .nodePort}}{{.nodePort}}{{"\n"}}{{end}}{{end}}{{end}}'

This gets all services in all namespaces, and does basically: "for each service, for each port, if nodePort is defined, print nodePort".
