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.

The On-Prem Kubernetes Reality Check

I know what you’re thinking – 0n-prem? Why is this guy teaching us about on-prem Kubernetes? It’s all in the cloud!

Although it may seem like that from tech marketing and large cloud providers screaming Kubernetes at the top of their lungs, in the production world, there are a lot of on-prem Kubernetes clusters and a lot of engineers managing them. Mercedes-Benz, a popular German car manufacturer, hosts over 900 Kubernetes clusters on OpenStack, which is a private cloud solution. All those clusters are sitting in a data center, not in the public cloud. If you peel back the layers of the onion and wonder how cloud providers are running Kubernetes clusters, they’re doing something similar. They have several data centers that are running Kubernetes just like you would on-prem or on a server that you can buy on eBay. The only difference is the cloud providers are running Kubernetes at a major scale around the world. However...
