Kubernetes is a powerful tool. It can help you manage complex applications and provide you with the ability to easily automate tasks involved in managing them. In this course, we will start exploring Kubernetes from a beginner's standpoint. We will discuss what Kubernetes is and what it does, and we will work with some of the basic functionality of Kubernetes hands-on. We will build a simple Kubernetes cluster. We will also deploy a sample microservice application to the cluster in order to explore how Kubernetes can help easily manage such applications.

A Practical Guide to Kubernetes

## Authentication
Since John is not around, we'll do some role-playing and impersonate him.
### Configuring kubectl
John will first have to set the cluster using the address and the certificate authority we sent him.

kubectl config set-cluster jdoe \
    --certificate-authority \
    keys/ca.crt \
    --server $SERVER

We created a new cluster called `jdoe`. 

Please note that the command we executed created just another config entry that enables to access all resources that currently exist in the cluster. It manipulated local text file, without changing anything in the existing cluster.
### Setting the Credentials
Next, he'll have to set the credentials using the certificate and the key we created for him.

In this lesson, we will impersonate John and try to get the access authenticated.
