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.

Technical requirements

To complete this chapter, you should first go over Chapter 2 and Chapter 3. Although that might sound obvious, we want to point it out as it’s crucial to understand the different deployment methods before diving into the on-prem needs of Kubernetes. Because cloud-based Kubernetes deployments abstract a lot of what you would do with on-prem, it still shows you the overall workflow of what components need to be deployed.

To work on this chapter, you should have some type of infrastructure and troubleshooting background. When it comes to on-prem Kubernetes clusters, they are extremely infrastructure-heavy, so getting through this chapter without that knowledge may be difficult. At the very least, you should have the following:

  • Linux knowledge
  • Server knowledge
