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

# Summary

Everything we learned led us to Deployments. Pods must not be created directly, but through ReplicaSets which, similarly, must not be created directly, but through Deployments. They are the objects that allow us not only to create the ReplicaSets and Pods, but that can also be updated without producing any downtime (when applications are designed accordingly). 

We combined Deployments with Services so that Pods can communicate with each other, or can be accessed from outside a cluster. All in all, we have everything we need to release our services to production. That is not to say that we understand all the crucial aspects of Kubernetes. We're not even close to that point. But, we do have almost everything we need for running some types of applications in production. What we're missing is networking.


# Destroying Everything
Before we enter the next stage of our knowledge seeking mission, we'll destroy the cluster we're running and give our machines a break.

This lesson summarises what we have learned so far in this section and what we are going to learn next.
