Overview of this book

Kubernetes is a trending topic among engineers, CTOs, CIOs, and other technically sound professionals. Due to its proliferation and importance for all cloud technologies, DevOps engineers nowadays need a solid grasp of key Kubernetes concepts to help their organization thrive. This book equips you with all the requisite information about how Kubernetes works and how to use it for the best results. You’ll learn everything from why cloud native is important to implementing Kubernetes clusters to deploying applications in production. This book takes you on a learning journey, starting from what cloud native is and how to get started with Kubernetes in the cloud, on-premises, and PaaS environments such as OpenShift. Next, you’ll learn about deploying applications in many ways, including Deployment specs, Ingress Specs, and StatefulSet specs. Finally, you’ll be comfortable working with Kubernetes monitoring, observability, and security. Each chapter of 50 Kubernetes Concepts Every DevOps Engineer Should Know is built upon the previous chapter, ensuring that you develop practical skills as you work through the code examples in GitHub, allowing you to follow along while giving you practical knowledge. By the end of this book, you’ll be able to implement Kubernetes in any environment, whether it’s an existing environment, a greenfield environment, or your very own lab running in the cloud or your home.

Summary

As you went through this chapter, there may have been some thoughts in your head of pure confusion. That’s okay—we’re all trying to get it when it comes to security in general, especially in Kubernetes.

Kubernetes security is an advanced topic, which is why the goal was to leave this topic for the last chapter of the book. Without Kubernetes security, environments will continue to be targets for attackers. However, before understanding Kubernetes security, you must fully understand how to utilize Kubernetes in production. The goal of Chapters 1-7 was to help with understanding Kubernetes in production.

The next goal, once you close this book, is to take what you’ve learned in this chapter along with the various methodologies highlighted and implement them in your production environment for optimal results.
