🚨 Terraform Directory Structure – The Right Way! 🚨

 A well-structured Terraform directory ensures scalability, reusability, and efficient infrastructure management. Let’s dive into the best practices! 👇

---

1️⃣ Environments – Separate Configs for Dev, Stage & Prod

Managing multiple environments? Structure them like this:
📂 Dev/
📂 Stage/
📂 Prod/

Each environment contains:
✅ main.tf – Defines cloud resources
✅ variables.tf – Declares variables (no values)
✅ outputs.tf – Stores outputs for dependencies
🚫 Instead of individual terraform.tfvars in each folder...

Use a central .tfvars folder like:
📂 Env/
✅ dev.tfvars – Development values
✅ stage.tfvars – Staging values
✅ prod.tfvars – Production values

⚡ Why?
✔️ Isolates environments safely
✔️ Avoids accidental changes in Prod
✔️ Modular and reusable configuration

⚡ Modules – Reusable Infrastructure Components

Stop repeating yourself – use modules!
📌 VPC Module – Creates your Virtual Private Cloud
📌 EC2 Module – Manages EC2 instances

⚡ Why?
🚀 Define once, use everywhere
🔁 Ensures consistency
⚙️ Speeds up deployments – just call the module!

---

⚡ Scripts – Automate Terraform Workflows

Automation is essential in DevOps & IaC. Scripts to include:
⚙️ init.sh – Initializes Terraform
🛑 teardown.sh – Destroys infrastructure (cost-saving)

⚡ Why?
⏱️ Saves time
❌ Reduces manual setup errors

---

⚡ Core Terraform Files – The Brains of Your Infra

These are critical to every Terraform project:
✅ provider.tf – Cloud provider config (AWS, GCP, Azure)
✅ backend.tf – Manages state (e.g., S3, Terraform Cloud)

⚡ Why?
🔐 Keeps state secure (no local files!)
👥 Avoids team conflicts

---

🔍 Why This Structure Matters:

✅ Organized & scalable projects
✅ Protects production environments
✅ Reusable, modular infra with modules
✅ Streamlined automation with scripts

---

💡 Pro Tip: Pair this structure with version control & CI/CD for ultimate IaC hygiene!
