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 this chapter, you should already know a bit about cloud technologies. The gist is that all clouds are more or less the same. There are differences in the names of the services, but they’re all doing the same thing more or less.

If you’re comfortable with the cloud and have worked in a few cloud-based services, you’ll be successful in navigating this chapter.

To work inside the cloud-based services, you will need the following:

  • A Linode account
  • A DigitalOcean account
  • A Red Hat account
  • An AWS account (for the final section of this chapter)

You can sign up for all of these services and get free credit. Just ensure that you shut down the Kubernetes environments when you’ve finished running them to save money.
