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

After running "kubeinit" command, kubernetes asks you to run following as regular user

mkdir -p $HOME/.kube

sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config

sudo chown $(id -u):$(id -g) $HOME/.kube/config

But if you run this as a regular user, you will get "The connection to the server localhost:8080 was refused - did you specify the right host or port?" when trying to access as a root user and vice versa. So try accessing "kubectl" as the user who executed the above commands.
