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.

Summary

Overall, containerized application deployment, troubleshooting, and third-party tooling are going to be the core pieces of what your Kubernetes cluster looks like. Without proper troubleshooting, you won’t have successful deployments. Without third-party tooling such as Ingress controllers, you won’t be able to properly manage frontend apps. Out of the box, Kubernetes gives you a ton to use to make things work. However, there are more steps you need to take. For better or for worse, Kubernetes isn’t one of those platforms where you can just deploy it and walk away. It takes management and engineering skills to ensure it’s working as expected.

In the next chapter, you’ll learn about how to monitor the workloads you’ve been deploying throughout this book.
