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).

Provisioning a Platform

Every chapter in this book, up until this point, has focused on the infrastructure of your cluster. We have explored how to deploy Kubernetes, how to secure it, and how to monitor it. What we haven't talked about is how to deploy applications.

In this, our final chapter, we're going to work on building an application deployment platform using what we've learned about Kubernetes. We're going to build our platform based on some common enterprise requirements. Where we can't directly implement a requirement, because building a platform on Kubernetes can fill its own book, we'll call it out and provide some insights.

In this chapter, we will cover the following topics:

  • Designing a pipeline
  • Preparing our cluster
  • Deploying GitLab
  • Deploying Tekton
  • Deploying ArgoCD
  • Automating project onboarding using OpenUnison

You'll have a good starting point for building out you own GitOps...
