How I Built a Secure Terraform Module to Deploy EKS on AWS (and Launched It as a Product)

I recently found myself rebuilding the same EKS infrastructure for every new project — IAM roles, node groups, tagging, GitOps setup… all from scratch.

So I decided to turn it into a product.

---

What It Does:

• Provisions a secure EKS cluster with managed node groups
• Modular IAM roles with AWS-managed policies
• Multi-AZ subnet support
• Comes with a clean starter example
• CI/CD- and GitOps-ready layout

---

What’s Included:

• eks module (EKS + node group)
• iam module (secure roles)
• Add-ons in development (ALB Ingress, Cluster Autoscaler)

---

Try It:

Starter GitHub repo:

https://github.com/Eng-Mike/terraform-aws-eks-secure

Full Production-Ready Version (Gumroad):

https://karengera.gumroad.com/l/terraform-eks-eks-secure

---

Why I Built It:

• I needed a secure and repeatable way to deploy EKS for clients.
• Every project had slightly different IAM, node configs, and tagging needs.
• I wanted to give back to the community while learning how to launch a real micro-product.

---

📈 What’s Next:

• CI/CD add-on (GitHub Actions)
• Monitoring templates (Prometheus + Grafana)
• ArgoCD GitOps deployment pattern

Let me know what you'd want to see added!
