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.

Working with AWS Fargate

Throughout this book, we have used Elastic Compute Cloud (EC2) instances as worker nodes for our Elastic Kubernetes Service (EKS) cluster, but AWS Fargate can be used as an alternative to host Pods. As we will see later on, Fargate can be used to provide a more secure operating environment for a Pod and can also be more cost-effective (but not always).

In some cases, you want to deploy a workload/application that runs infrequently, has a small memory/CPU footprint, and/or needs enhanced security, for example, creating a regular dump of a production database. Fargate can be used to meet all of these requirements. In this chapter, we will dive into more detail on how and when you should use AWS Fargate, as well as how it works with EKS to provide an alternative to EC2-based worker nodes. Specifically, we will cover the following topics:

  • What AWS Fargate is and how is it priced
  • How to create a Fargate profile in EKS
  • How to deploy a Pod to a...
