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.

Getting the Ball Rolling with Kubernetes and the Top Three Cloud Platforms

When starting your Kubernetes journey, the typical first step is to create a Kubernetes cluster to work with. The reason why is that if you, for example, start by creating a Kubernetes Manifest (more on this in later chapters), you’ll have nowhere to deploy the Manifest to because you don’t have a Kubernetes cluster. The other reality when it comes to Kubernetes is there’s a ton of cloud-native operations management – things such as monitoring a cluster, automating the deployment of a cluster, and scaling a cluster. Because of that, understanding cluster creation is a crucial step in your Kubernetes journey.

In the previous chapter, you learned not only about why Kubernetes is important but also the backstory of why engineers want to use orchestration in today’s world. In this chapter, you’re going to hit the ground running by creating and managing your very own Kubernetes...
