Kubernetes and Docker - An Enterprise Guide

Overview of this book

Containerization has changed the DevOps game completely, with Docker and Kubernetes playing important roles in altering the flow of app creation and deployment. This book will help you acquire the knowledge and tools required to integrate Kubernetes clusters in an enterprise environment. The book begins by introducing you to Docker and Kubernetes fundamentals, including a review of basic Kubernetes objects. You’ll then get to grips with containerization and understand its core functionalities, including how to create ephemeral multinode clusters using kind. As you make progress, you’ll learn about cluster architecture, Kubernetes cluster deployment, and cluster management, and get started with application deployment. Moving on, you’ll find out how to integrate your container to a cloud platform and integrate tools including MetalLB, externalDNS, OpenID connect (OIDC), pod security policies (PSPs), Open Policy Agent (OPA), Falco, and Velero. Finally, you will discover how to deploy an entire platform to the cloud using continuous integration and continuous delivery (CI/CD). By the end of this Kubernetes book, you will have learned how to create development clusters for testing applications and Kubernetes components, and be able to secure and audit a cluster by implementing various open-source solutions including OpenUnison, OPA, Falco, Kibana, and Velero.

Summary

Coming into this chapter, we hadn't spent much time on deploying applications. We wanted to close things out with a brief introduction to application deployment and automation. We learned about pipelines, how they are built, and how they run on a Kubernetes cluster. We explored the process of building a platform by deploying GitLab for source control, built out a Tekton pipeline to work in a GitOps model, and used ArgoCD to make the GitOps model a reality. Finally, we automated the entire process with OpenUnison.

Using the information in this chapter should give you direction as to how you want to build your own platform. Using the practical examples in this chapter will help you map the requirements in your organization to the technology needed to automate your infrastructure. The platform we built in this chapter is far from complete. It should give you a map for planning your own platform that matches your needs.

Finally, thank you. Thank you for joining us on...
