Overview of this book

Thanks to its extensive support for managing hundreds of containers that run cloud-native applications, Kubernetes is the most popular open source container orchestration platform that makes cluster management easy. This workshop adopts a practical approach to get you acquainted with the Kubernetes environment and its applications. Starting with an introduction to the fundamentals of Kubernetes, you’ll install and set up your Kubernetes environment. You’ll understand how to write YAML files and deploy your first simple web application container using Pod. You’ll then assign human-friendly names to Pods, explore various Kubernetes entities and functions, and discover when to use them. As you work through the chapters, this Kubernetes book will show you how you can make full-scale use of Kubernetes by applying a variety of techniques for designing components and deploying clusters. You’ll also get to grips with security policies for limiting access to certain functions inside the cluster. Toward the end of the book, you’ll get a rundown of Kubernetes advanced features for building your own controller and upgrading to a Kubernetes cluster without downtime. By the end of this workshop, you’ll be able to manage containers and run cloud-based applications efficiently using Kubernetes.

Preface

Summary

As we mentioned in the introduction, most applications need to store or retrieve data for a lot of different reasons. In this chapter, we saw that Kubernetes provides various ways of provisioning storage for not just storing the state of an application, but also for the long-term storage of data.

We have covered ways to use storage for our application running inside pods. We saw how we can use the different types of Volumes to share temporary data among containers running in the same pod. We also learned how to persist data across pod restarts. We learned how to manually provision PVs to create PVCs to bind to those Volumes, as well as how to create pods that can use these claims as Volumes mounted on their containers. Next, we learned how to request storage dynamically using only the PVCs with pre-created storage classes. We also learned about the life cycle of these volumes with respect to that of the pods.

In the next chapter, we will extend these concepts further...
