Overview of this book

With its broad adoption across various industries, Kubernetes is helping engineers with the orchestration and automation of container deployments on a large scale, making it the leading container orchestration system and the most popular choice for running containerized applications. This Kubernetes book starts with an introduction to Kubernetes and containerization, covering the setup of your local development environment and the roles of the most important Kubernetes components. Along with covering the core concepts necessary to make the most of your infrastructure, this book will also help you get acquainted with the fundamentals of Kubernetes. As you advance, you'll learn how to manage Kubernetes clusters on cloud platforms, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), and develop and deploy real-world applications in Kubernetes using practical examples. Additionally, you'll get to grips with managing microservices along with best practices. By the end of this book, you'll be equipped with battle-tested knowledge of advanced Kubernetes topics, such as scheduling of Pods and managing incoming traffic to the cluster, and be ready to work with Kubernetes on cloud platforms.

Chapter 9: Persistent Storage in Kubernetes

So far, we've learned about Kubernetes' key concepts, and this chapter is going to be the last one about Kubernetes' core concepts. So far, you've understood that Kubernetes is all about creating an object in the etcd datastore that will be converted into actual computing resources on the Nodes that are part of your cluster.

This chapter will focus on a concept called PersistentVolume. This is going to be another object that you will need to master in order to get persistent storage on your cluster. Persistent storage is achieved in Kubernetes by using the PersistentVolume resource kind, which has its own mechanics. Honestly, these can be relatively difficult to approach at first, but we are going to discover all of that!

In this chapter, we're going to cover the following main topics:

  • Why you would want to use PersistentVolume
  • Understanding how to mount PersistentVolume to your Pod claims
  • Understanding...
