The Kubernetes Workshop

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

In this chapter, we covered the different ways in which we can expose our application running on Pods. We have seen how we can use a ClusterIP Service to expose an application inside the cluster. We have also seen how we can use a NodePort Service to expose an application outside the cluster. We have also covered the LoadBalancer and ExternalName Services in brief.

Now that we have created a Deployment and learned how to make it accessible from the external world, in the next chapter, we will focus on storage aspects. There, we will cover reading and storing data on disk, in and across Pods.
