How to fix issue of 'Unable to connect to the server: EOF' Kubernetes - Kubectl

Question

When I try any kubectl command, it always returns:

Unable to connect to the server: EOF 

I followed these tutorials:

https://kubernetes.io/docs/tasks/tools/install-kubectl/

https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters/

But they have not helped me. According to the first link, by default, kubectl configuration is located at

~/.kube/config 

But in that path I don't have anything. I don't know if this is causing the issue.

Other thing is when I try to check the kubectl configuration:

M:.kube candres$ kubectl cluster-info Kubernetes master is running at http://localhost:8080  To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'. Unable to connect to the server: EOF M:.kube candres$ kubectl cluster-info dump Unable to connect to the server: EOF 

The versions I have installed are:

Kubernetes - kubectl

M:.kube candres$ kubectl version Client Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.3", GitCommit:"X", GitTreeState:"clean", BuildDate:"2018-02-09T21:51:06Z", GoVersion:"go1.9.4", Compiler:"gc", Platform:"darwin/amd64"} Unable to connect to the server: EOF 

Minikube

M:.kube candres$ minikube version minikube version: v0.25.0 

Docker:

M:.kube candres$ docker version Client:  Version:   17.12.0-ce  API version:   1.35  Go version:    go1.9.2  Git commit:    X  Built: Wed Dec 27 20:03:51 2017  OS/Arch:   darwin/amd64  Server:  Engine:   Version:  17.12.0-ce   API version:  1.35 (minimum version 1.12)   Go version:   go1.9.2   Git commit:   X   Built:    Wed Dec 27 20:12:29 2017   OS/Arch:  linux/amd64   Experimental: true 

Does anyone know how to resolve this?

After Minikube is started, kubectl is configured automatically.

minikube start Starting local Kubernetes cluster... Kubernetes is available at https://192.168.99.100:8443. Kubectl is now configured to use the cluster. 

You can verify and validate the cluster and context with following commands.

kubectl config view
