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

The good news is that ReplicaSets are relatively straightforward. They provide a guarantee that the specified number of replicas of a Pod will be running in the system as long as there are available resources. That's the primary and, arguably, the only purpose.

The bad news is that ReplicaSets are rarely used independently. You will almost never create a ReplicaSet directly just as you're not going to create Pods. Instead, we tend to create ReplicaSets through Deployments. In other words, we use ReplicaSets to create and control Pods, and Deployments to create ReplicaSets (and a few other things). We'll get to Deployment soon. 
# Destroying the Cluster
For now, please delete your local Minikube cluster. The next chapter will start from scratch.

This lesson summarizes what we have learned so far and what's coming up next.
