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.

Summary

In this chapter, we explored how EBS (block) differs from EFS (filesystem) storage. We identified that EBS is normally used where you need to provide dedicated volumes per Pod, is fixed in size, and is charged as soon as you provision it. Meanwhile, EFS is shared storage and can therefore be mounted across multiple Pods, can scale as needed, and you are only charged for what you use.

We also discussed how EFS requires more setup than EBS, as the EBS filesystem and mount targets need to be deployed prior to it being used in EKS. EFS can be viewed as more complex to set up as it’s a shared storage platform, whereas EBS is just network-attached storage for a single node. EBS is generally cheaper to provision and use but it is mostly only used for columns attached to a single instance (EC2).

We then reviewed how to install the CSI drivers, creating an add-on for the EBS CSI driver and Helm for the EFS CSI driver. Once the drivers were installed, we explored the Kubernetes...
