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

In this chapter, you learned about the Kubernetes SIG project called KinD.We went into details on how to install optional components in a KinD cluster, including Calico as the CNI and NGINX as the Ingress controller. Finally, we covered the details of the Kubernetes storage objects that are included with a KinD cluster.

Hopefully, with the help of this chapter, you now understand the power that using KinD can bring to you and your organization. It offers an easy to deploy, fully configurable Kubernetes cluster. The number of running clusters on a single host is theoretically limited only by the host resources.

In the next chapter, we will dive into Kubernetes objects. We've called the next chapter Kubernetes Bootcamp since it will cover the majority of the base Kubernetes objects and what each one is used for. The next chapter can be considered a "Kubernetes pocket guide." It contains a quick reference to Kubernetes objects and what they do, as well as...
