# Amazon EKS Setup

This Terraform module provisions a fully functional **Amazon EKS cluster** using Cloud Posse modules. It standardizes naming and tagging via `terraform-null-label`, creates the EKS control plane, manages access through `aws-auth`, and sets up **IAM roles and policies** (including an EKS admin role).

Optionally, it also:

* Creates **managed node groups** and/or **Fargate profiles**

* Enables **cluster logging**, **encryption**, and **EKS add-ons**

* Creates a **Kubernetes namespace**

* Installs the **Secrets Store CSI Driver** via Helm
