did you specify the right host or port? error on Kubernetes

Question

I have followed the helloword tutorial on http://kubernetes.io/docs/hellonode/.

When I run:

kubectl run hello-node --image=gcr.io/PROJECT_ID/hello-node         


        

Answer 1

I was getting an error when running

sudo kubectl get pods
The connection to the server localhost:8080 was refused - did you specify the right host or port?

Finally for my environment this command parameter works

sudo kubectl --kubeconfig /etc/kubernetes/admin.conf get pods

when executing kubectl as non root.
