infra-zero

Zero to production-ready infrastructure using Terraform on AWS (Free Tier)

---

Problem

Setting up cloud infrastructure manually is:

• slow
• error-prone
• not reproducible

This project solves that by:

→ Defining infrastructure as code

→ Automating provisioning

→ Making deployments consistent and repeatable

---

What It Does

• Provisions EC2 instance on AWS
• Configures security groups (SSH + HTTP)
• Automatically installs and runs Nginx
• Outputs public IP after deployment
• Runs Terraform plan via GitHub Actions (CI/CD)

---

Tech Stack

• AWS (EC2, Security Groups)
• Terraform
• GitHub Actions (CI/CD)
• Linux (Ubuntu)
• Nginx

Key Features

• Infrastructure as Code (Terraform)
• Automated provisioning (no manual SSH setup required)
• CI/CD pipeline for infrastructure validation
• Free-tier friendly setup

---

How to Use

1. Clone repo

git clone https://github.com/ak3ph/infra-zero.git
cd infra-zero/terraform

---

2. Configure AWS

aws configure

---

3. Deploy

terraform init
terraform apply

---

4. Access

Open in browser:

http://<output-public-ip>

---

CI/CD

On every push:

• Terraform init runs
• Terraform plan runs
• Infrastructure changes are validated automatically

---

Notes

• Uses AWS Free Tier (t2.micro)
• Public IP may change on recreation
• For production → use Elastic IP

---

Learnings

• Terraform basics and resource lifecycle
• AWS EC2 provisioning
• Security group configuration
• Cloud-init & user_data automation
• CI/CD for infrastructure
• Debugging real-world infra issues

---

Future Improvements

• Add Elastic IP (static IP)
• Add domain (Route53)
• Add HTTPS (Let's Encrypt)
• Add load balancer
• Modular Terraform structure
