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.

Visualizing your workloads

Throughout the book and in the real world, you will mainly interact with EKS through the command line or a CI/CD pipeline. It is, however, sometimes useful to be able to view what you have running on a cluster in a visual form. Kubernetes provides a web dashboard, but with EKS, you can see most of the cluster configuration through the main EKS and using CloudWatch (discussed more in Chapter 19, Developing on EKS), which has removed the need to deploy a separate dashboard. To access the console, sign in to http://aws.amazon.com and log in with credentials that are allowed to view the cluster (see Chapter 3, Building Your First EKS Cluster). You can then select Amazon Elastic Kubernetes Service | Clusters and you will be presented with a list of clusters running in the region (you can now add on-premise clusters as well). From the main view, you can see clusters, their version, and whether they need updating (discussed more in Chapter 10, Upgrading EKS Cluster...
