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.

Building clusters with EKS Blueprints and Terraform

In this book, we mainly used eksctl to build our clusters and leverage add-ons to support simpler upgrades of standard components, such as the VPC CNI plugin or kube-proxy. We also deployed additional software such as Prometheus and KEDA (Chapter 18). EKS blueprints provides you with a way to build an opinionated cluster, with this operational software already deployed. This simplifies the job of the platform of DevOps engineers, and they can use blueprints to repeatedly build clusters for different environments and/or teams with very little effort.

EKS Blueprint Clusters are built using AWS CDK, which is a set of libraries and constructs that allow you to create and deploy complex CloudFormation templates, using standard programming languages such as TypeScript or Python. Recently, AWS has released EKS Blueprints for Terraform, and this is what we will use in the rest of the section to create a cluster that can be used by our...
