Overview of this book

Kubernetes has emerged as the de facto standard for container orchestration, with recent developments making it easy to deploy and handle a Kubernetes cluster. However, a few challenges such as networking, load balancing, monitoring, and security remain. To address these issues, Amazon EKS offers a managed Kubernetes service to improve the performance, scalability, reliability, and availability of AWS infrastructure and integrate with AWS networking and security services with ease. You’ll begin by exploring the fundamentals of Docker, Kubernetes, Amazon EKS, and its architecture along with different ways to set up EKS. Next, you’ll find out how to manage Amazon EKS, encompassing security, cluster authentication, networking, and cluster version upgrades. As you advance, you’ll discover best practices and learn to deploy applications on Amazon EKS through different use cases, including pushing images to ECR and setting up storage and load balancing. With the help of several actionable practices and scenarios, you’ll gain the know-how to resolve scaling and monitoring issues. Finally, you will overcome the challenges in EKS by developing the right skill set to troubleshoot common issues with the right logic. By the end of this Kubernetes book, you’ll be able to effectively manage your own Kubernetes clusters and other components on AWS.

Understanding the different configuration options for an EKS cluster

Kubernetes is extensible by default, which is one of the reasons it has become so popular. As well as the standard API objects we’ve already discussed such as Pods and Services, you can extend the API to support custom resources, controllers, operators, and standard plugins for networking and storage. All of these elements can be added to an EKS cluster as part of the cluster creation process; however, in this chapter, we will cover the basic configuration to get a simple cluster up and running. The following table defines what will be configured as well as providing a map to other chapters that show additional configuration steps:

As we have mentioned, EKS is really a managed control plane, so this must always be done, and...
