Remote access to Minikube with Kubectl

Let's say you need to install a Kubernetes cluster in your organization for development and testing purposes. Minikube looks like a perfect fit for that job. It was specially designed for users looking to try out Kubernetes or develop with it day-to-day. It runs a single-node Kubernetes cluster inside a VM on a standalone machine. So, you found a server for that, followed the insulation guide to install a virtual box with Minikube on it and now you can easily deploy pods to the K8s cluster with kubectl from that server. In order to be able to do the same remotely from your laptop you have to do some extra movements:

1. Install kubectl on your laptop if you don't have it.
2. Copy .minikube folder from the server with Minikube to your laptop (e.g. to /Users/fedor/work/minikube)
3. Update clusters, contexts and users sections in your kubectl config file on your laptop ($HOME/.kube/config) with the following content
apiVersion: v1
clusters:
- cluster:   
    insecure-skip-tls-verify: true
    server: https://YOUR_SERVER:51928
  name: minikube
contexts:
- context:
    cluster: minikube
    user: minikube
  name: minikube
current-context: minikube
kind: Config
preferences: {}
users:
- name: minikube
  user:
    client-certificate: /Users/fedor/work/minikube/client.crt
    client-key: /Users/fedor/work/minikube/client.key

4. Go to the server and stop Minikube with
minikube stop
5. Forward a port for the Minikube VM from 8443 guest port to 51928 host port.


6. Start Minikube with  
minikube start
7. Check from your laptop that it works:
kubectl get pods

That's it!
