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.

Installing and configuring the AWS CSI drivers in your cluster

We will install both the EBS and EFS drivers in this section. You will need a similar process for both, detailed next:

  1. Create an Identity and Access Management (IAM) policy that will allow the plugin to perform AWS API calls for either EBS or EFS.
  2. Create and map an IAM role to an EKS service account (this is discussed in detail in Chapter 1)3.
  3. Deploy the plugin and configure it to use the service account created in step 2.

Installing and configuring the EBS CSI driver

The driver can be found at https://github.com/kubernetes-sigs/aws-ebs-csi-driver. Let’s get down to installing it!

  1. You can create the IAM policy from scratch or you can use the AmazonEBSCSIDriverPolicy AWS-managed policy.
  2. We can now create the role. We will use the –role-only command-line switch, so we don’t create the EKS service account. Using the following eksctl command, adjust the command line...
