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 also getting same below error:

Unable to connect to the server: dial tcp [::1]:8080: connectex: No connection could be made because the target machine actively refused it.

Then I just execute below command and found everything working fine.

PS C:> .\minikube.exe start
