Build a complete multi-environment infrastructure using Terraform best practices. Create reusable modules, manage state, configure workspaces for dev/staging/prod, and implement security controls.

Learning Objectives

Structure a production-ready Terraform project

Create reusable infrastructure modules

Implement variables, locals, and outputs effectively

Use workspaces to manage multiple environments

Apply security best practices for secrets and state

Understand the full Terraform workflow

Step 1

Initialize the project structure

Create a well-organized Terraform project directory structure.

Commands to Run

cd ~

mkdir -p terraform-infra-project/{modules/app,environments}

cd terraform-infra-project

tree . 2>/dev/null || find . -type d | head -20

What This Does

Good project structure separates modules (reusable components) from environments (where you deploy). This mirrors how real teams organize Terraform code. modules/ contains reusable infrastructure. environments/ can hold environment-specific configs.

Expected Outcome

Directory structure created with modules/app and environments folders. Ready for Terraform files.

Pro Tips

1
This is YOUR infrastructure project - customize it!
2
modules/ = reusable building blocks
3
Keep root module simple, complexity in child modules
4
This structure scales to large organizations
5
We'll add files step by step

Common Mistakes to Avoid

⚠️Putting everything in one giant file
⚠️No separation between modules and environments
⚠️Skipping organization (causes pain later)
