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.

In the previous chapter, you dove into different deployment scenarios and how you should think not only about controllers, but also about upgrading apps, different types of apps to deploy, and different methods for getting an app up and running. In this chapter, you’re going to dive a bit deeper into the different styles of deploying and troubleshooting versus just doing the deployment.

The first step in any type of deployment is figuring out what you’re doing – what type of application it is, what type of Kubernetes resource you want to use, and the different plugins that you may want to use, such as a CSI. After you figure out the logistics of what you want to deploy, the next step is to think about how you want to deploy.

With Kubernetes, there are many different deployment methods – automated deployments, manual deployments, and something in between automated and manual. There’s a vast...
