☁️ Terraform Beginner to Intermediate to Advance Project — By Muhammad Uzair Saeedi

This repository demonstrates how to use Terraform to provision AWS infrastructure step-by-step — starting from basic S3 bucket creation to fully modular multi‑environment AWS deployments with Terraform state management using S3 & DynamoDB.

The project is organized by learning days:

Day	Topic	Concepts Learned
✅ Day‑1	Local File + S3	Basic Terraform resources & providers
✅ Day‑2	VPC + EC2	Networking, EC2, Key Pair, Public subnet
✅ Day‑3	Remote State (S3 + DynamoDB)	Terraform state locking & backend config
✅ Day‑4	Terraform Modules + Multi‑Environment	Re‑usable modules, staging/prod infra

🛠️ Tools and Requirements

• ✅ AWS Account
• ✅ AWS CLI Installed & Configured (aws configure)
• ✅ Terraform Installed
• ✅ SSH Key for EC2 (terra-key-ec2.pub)

☁️ Day‑1 — Local + S3 Setup

Commands:

cd Day-1
terraform init
terraform plan
terraform apply -auto-approve

Creates:

Resource	Description
local_file	Creates a local file
aws_s3_bucket	Creates S3 bucket

---

🌐 Day‑2 — VPC, Security Group and EC2

Commands:

cd Day-2
terraform init
terraform apply -auto-approve

Creates:

• Custom VPC
• Public subnet
• IGW + Route Table
• Security Group
• Key‑pair
• EC2 instance

SSH:

ssh -i "terra-key-ec2" ubuntu@<EC2_PUBLIC_IP>

---

🛑 Day‑3 — Remote Terraform State Management

Day‑3 introduces:

Component	Purpose
S3 Bucket	Stores Terraform state
DynamoDB	State locking (prevents corruption)

Commands:

cd Day-3
terraform init
terraform apply -auto-approve

---

🏗️ Day‑4 — Terraform Modules + Multi‑Environment Infra

✅ Uses Terraform Registry VPC Module

Creates:

• VPC
• Public + Private Subnets
• NAT + VPN

✅ Multi‑Environment Structure

Environments:

• dev
• staging
• prod

Each env creates:

• EC2 Instances
• S3 Bucket
• DynamoDB Table
• Key Pair
• Security Group

Run:

cd Day-4/terraform-modules-app
terraform init
terraform apply -auto-approve

---

🧱 Terraform Commands Reference

Command	Description
terraform init	Initialize
terraform plan	Preview changes
terraform apply	Apply infra
terraform destroy	Delete infra
terraform state list	List state objects

---

🧹 Cleanup Instructions

terraform destroy -auto-approve

Run destroy inside each day's folder separately

---
