Terraform Stacks

#webdev #terraform #devops #infrastructureascode

terraform-stacks

A collection of production-ready Terraform Stacks that showcase enterprise patterns across full applications, multi-region fan-out, and Kubernetes platforms. Each stack is a single hand-off artifact—complete with documentation, diagrams, and well-commented code—that platform teams can share with application squads to accelerate delivery.

Why Terraform Stacks?

Stacks let you compose multiple Terraform components into a single, versioned unit. Platform teams can ship one stack.hcl that wires dependencies (networking → storage → compute → operations) and expose only the inputs that matter. Consumers get a self-service experience without having to understand the underlying module graph.

Key advantages inspired by real-world platform teams and recent Stacks guidance:

  • Single artifact delivery: one stack definition to deploy a whole footprint (network, data, compute, observability) with dependency ordering handled for you.
  • Consistent multi-environment rollouts: define multiple deployments (prod, staging, regions, or accounts) in the Stack; changes fan out automatically without copy/paste Terraform.
  • Guardrails by default: opinionated tags, encryption, IAM scoping, dashboards, and alarms shipped in every stack to meet enterprise baselines.
  • Speed with safety: smaller plan surfaces and fewer moving parts versus layered, loosely coupled workspaces; easier to review, promote, and roll back.

Projects

Each project is ready to clone, customize, and deploy. Read the per-stack README for inputs, outputs, and diagrams.

  • Application Stack (Project 1): Deploy a full web application—VPC, ALB + ECS Fargate, RDS + Secrets Manager, dashboards, and alarms—as a single Stack with multi-deployment fan-out.
  • Multi-Region Stack (Project 2): Stamp the same service across regions or accounts, including Route53 failover, ALB + ECS, and DynamoDB global tables, without duplicating Terraform.
  • Kubernetes Stack (Project 3): Provision EKS, managed node groups, and platform add-ons (ALB controller, metrics server) from one Stack, with IRSA wiring and kubeconfig outputs.

How to use this repository

  1. Pick a Stack that matches your use case and open its README for architecture, variables, and examples.
  2. Install Terraform with the Stacks feature flag (or use Terraform Cloud/Enterprise Stacks). Run terraform init and terraform plan inside the Stack folder to preview deployments.
  3. Customize inputs in stack.hcl deployments (e.g., regions, CIDRs, cluster sizes). The dependency graph is already wired for you.
  4. Promote with confidence: commit changes, run CI, and apply across deployments knowing that tagging, encryption, and observability baselines are built in.

These examples are inspired by the Stacks patterns described by HashiCorp and practitioners building paved roads for application teams.
