Chapter 5: Securing Private EKS Cluster for Production

This chapter will walk you through all the planning you require to create a production-grade private EKS cluster. It will cover most of the necessary topics, such as the Container Network Interface (Virtual Private Cloud CNI), network policy, logging, security, and observability for EKS clusters. It includes the implementation of a service mesh, and some must-have add-ons, such as Cluster Autoscaler, IAM Role for Service Accounts (IRSA), and the Elastic Block Store-Container Storage Interface (EBS-CSI) driver. We will verify whether Kubernetes is deployed securely using kubescape and kube-bench. We will apply policy and governance using Open Policy Agent (OPA) Gatekeeper. After that, we will perform the backup and restore of a StatefulSet using Velero.

In this chapter, we are going to cover the following main sections:

• Planning your fully private EKS cluster
• Creating your EKS cluster
• Deploying add-ons
