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.

Part 1: First 20 Kubernetes Concepts – In and Out of the Cloud

When engineers first dive into Kubernetes, it can almost feel like a tool of sorts. You use it to run and deploy containers. However, that’s not the case. Kubernetes in itself is a platform. It’s almost like a subset of a methodology to run containers. Kubernetes, among many other platforms, is why the whole platform engineer title is becoming so popular. The DevOps space is moving away from thinking about just tools and focusing on the entire platform and environment.

With different platforms comes the question – where do you run it? The first set of concepts in the 50 concepts will be explained here with the overall architecture of Kubernetes.

Kubernetes is something that’s heavily utilized in the cloud, but it’s also heavily utilized on-premises. An example of this is certain regulatory requirements. I was recently chatting with a colleague that works in the defense space...
