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

For the purpose of this chapter, you should already know how to navigate through each cloud portal and have a general understanding of how you can automate the creation of cloud infrastructure. Although it would be great to dive into those topics in this book, these topics are huge and there are whole books out there dedicated just to them. Because of that, you should know about automated workflows, Terraform, and the cloud prior to getting started.

To work inside the cloud, you will need the following, all of which you can sign up for and get free credit:

  • An Azure account
  • An AWS account
  • A GCP account
  • An infrastructure automation tool such as Terraform
