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.

Service meshes and Ingresses

Almost every containerized application needs to be routed in one way or another – whether it’s so outside users can use the application, applications can talk to each other, or one application needs to connect to another. Routes and Services are extremely important in Kubernetes, which is why service meshes and Ingresses play a huge part.

In many cases, you’ll need better visuals into what’s happening with services, how traffic is being routed, and what applications are routing to which load balancers and IP addresses. You’ll also eventually want a way to encrypt traffic between services, which Kubernetes doesn’t give you out of the box.

Service meshes and Ingresess are typically more advanced-level topics, but in this book and possibly at this stage in your career, you’ll be ready to dive in and fully understand the pros and cons of using these two tools, plugins, and platforms.
