Kubernetes – An Enterprise Guide - Second Edition

By: Marc Boorshtein, Scott Surovich

Overview of this book

Kubernetes has taken the world by storm, becoming the standard infrastructure for DevOps teams to develop, test, and run applications. With significant updates in each chapter, this revised edition will help you acquire the knowledge and tools required to integrate Kubernetes clusters in an enterprise environment. The book introduces you to Docker and Kubernetes fundamentals, including a review of basic Kubernetes objects. You’ll get to grips with containerization and understand its core functionalities such as creating ephemeral multinode clusters using KinD. The book has replaced PodSecurityPolicies (PSP) with OPA/Gatekeeper for PSP-like enforcement. You’ll integrate your container into a cloud platform and tools including MetalLB, externalDNS, OpenID connect (OIDC), Open Policy Agent (OPA), Falco, and Velero. After learning to deploy your core cluster, you’ll learn how to deploy Istio and how to deploy both monolithic applications and microservices into your service mesh. Finally, you will discover how to deploy an entire GitOps platform to Kubernetes using continuous integration and continuous delivery (CI/CD).

Technical requirements

This chapter has the following technical requirements:

  • A Docker host installed using the steps from Chapter 1, Docker and Container Essentials
  • Installation scripts from this book's GitHub repository

You can access the code for this chapter by going to this book's GitHub repository: https://github.com/PacktPublishing/Kubernetes---An-Enterprise-Guide-2E/tree/main/chapter2.

We thought it was important to point out that this chapter will reference multiple Kubernetes objects, some without a lot of context. Chapter 3, Kubernetes Bootcamp, goes over Kubernetes objects in detail, many with commands you can use to understand them, so we thought having a cluster to use while reading about this would be useful.

Most of the base Kubernetes topics covered in this chapter will be discussed in future chapters, so if some topics may be a bit foggy after you've read this chapter, don't fear! They will be discussed...
