Question

I have recently installed minikube and kubectl. However when I run kubectl get pods or any other command related to kubectl I get the error

Unable to connect to the server: unexpected EOF

Does anyone know how to fix this?I am using Ubuntu server 16.04.Thanks in advance.

The following steps can be used for further debugging.

1. Check the minikube local cluster status using minikube status command.

    $: minikube status
    minikube: Running
    cluster: Running
    kubectl: Correctly Configured: pointing to minikube-vm at 172.0.x.y
   

2. If problem with kubectl configuratuion,then configure it using, kubectl config use-context minikube command.

   $: kubectl config use-context minikube
   Switched to context "minikube".
   

3. Check the cluster status, using kubectl cluster-info command.

   $: kubectl cluster-info
   Kubernetes master is running at ...
   Heapster is running at ...
   KubeDNS is running at ...
   ...
   To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
   

Note: It can even be due to very simple reason: internet speed (it happend to me just now).
