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.

Troubleshooting Common Issues

Throughout the book, we have created clusters and added controllers, add-ons, workloads, and so on, but not everything has gone according to plan. And while K8s does a great job of being easy to use, you will probably have at least one issue following this book or in your day job.

Understanding how to troubleshoot and what tools to use to identify root causes and hopefully fix them is an important part of using or running Elastic Kubernetes Service (EKS). In this chapter, we will look at the common techniques and tools used with EKS, as well as the frequent errors you may see when using Amazon EKS.

In this chapter, we will cover a couple of common questions when you start using Amazon EKS, walk through the details, and learn how to do troubleshooting such as the following:

  • Common K8s tools/techniques for troubleshooting EKS
  • Common cluster access problems
  • Common Node/compute problems
  • Common Pod networking problems
  • Common workload...
