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

Deploying test releases as part of a continuous deployment process is not the only usage of Namespaces. There can be many other situations when they are useful. We could, for example, give a separate Namespace to each team in our organization. Or we could split the cluster into Namespaces based on the type of applications (e.g., monitoring, continuous-deployment, back-end, and so on). 

All in all, Namespaces are a handy way to separate the cluster into different sections. Some of the Namespaces we'll create will be long-lasting while others, like `testing` Namespace from our examples, will be short-lived.

The real power behind Namespaces comes when they are combined with authorization policies and constraints. However, we did not yet explore those subjects so, for now, we'll need to limit our Namespaces experience to their basic form.



# Destroying Everything
The chapter is finished, and that means that we are about to remove the cluster.

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