50 Kubernetes Concepts Every DevOps Engineer Should Know

By: Michael Levan

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.

What is Kubernetes PaaS and how does it differ?

Deploying Kubernetes clusters in different ways felt to engineers like it came in waves. First, there were raw Kubernetes clusters. You’d have to deploy everything manually, ranging from the Control Plane to the Certificate Authority (CA) and everything in between. After that, there were Kubernetes services in the cloud, such as AKS, GKE, and EKS. Now, there are serverless Kubernetes such as GKE AutoPilot and EKS Fargate, which you learned about in the previous chapter.

Another option that stands out, especially in the enterprise, is PaaS-based Kubernetes solutions such as Red Hat’s OpenShift.

In this section, you’re going to learn about why you’d want to use OpenShift, how enterprises are utilizing PaaS-based Kubernetes such as OpenShift, and how to get started with a Dev environment right on your local computer with OpenShift, develop and deploy production-ready OpenShift clusters in major cloud providers...
