What problem does it solve?

This guide provides reusable patterns and best practices for building Amazon EKS infrastructure with Terraform. It enables teams to scaffold clusters, node groups, add-ons, and IRSA configurations using a consistent, proven approach.

Core Features & Use Cases

• Complete EKS cluster scaffolds using the official terraform-aws-modules/eks/aws module (v20+).
• Node group and Fargate pattern configurations to match common production needs.
• IRSA patterns for service accounts and fine-grained permissions with managed identities.
• Add-ons configuration templates for CoreDNS, VPC CNI, and other essentials.
• Use Case: Rapidly bootstrap a secure, scalable EKS environment for multiple environments (dev, staging, prod) with repeatable patterns.

Quick Start

Generate an EKS infrastructure template set using the patterns described and adapt cluster_name and environment as needed.
