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.

Deploying Kubernetes Apps Like a True Cloud Native

When engineers start hearing about Kubernetes or want to start implementing it, the typical reason is from a Dev perspective of managing and deploying applications. The whole premise around Kubernetes making engineering teams’ lives easier, regardless of whether it’s Dev or Ops, is based on application deployment.

Deploying applications is at the forefront of every business’s mind, whether it’s a website, some mobile application, or an internal app in any company, from a software company to an auto-parts company to a beer manufacturer. Regardless of the industry, almost every company deploys some type of application and some type of software. As all engineers know, deploying and maintaining an application successfully isn’t an easy task. Whether you’re running an app on bare metal, on a VM, in the cloud, or even in a container, that app could be (and most likely is) the make or break between...
