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 had the same issue after a reboot, I followed the guide described here

So try the following:

$ sudo -i
# swapoff -a
# exit
$ strace -eopenat kubectl version

After that it works fine.
