🚀 ChainElect Infrastructure

📌 Overview

ChainElect is a secure, blockchain-powered e-voting system that ensures transparency, integrity, and verifiability in elections.
This repository contains Infrastructure as Code (IaC) for deploying the ChainElect backend, frontend, and database on DigitalOcean using Terraform and Ansible.

🏗️ Infrastructure Setup

The infrastructure is fully automated using:

• Terraform → Manages DigitalOcean resources like Droplets, Load Balancer, VPC, and Database.
• Ansible → Configures servers, installs dependencies, and deploys the application.
• GitHub Actions CI/CD → Automates infrastructure deployment when updates are pushed.

🌍 DigitalOcean Infrastructure

Component	Technology	Description
Compute	Droplets	Backend & Frontend servers
Networking	Load Balancer, VPC, Firewall	Secure application networking
Database	PostgreSQL	Stores user credentials & voting data
Storage	Block Storage	Data persistence for the database
Deployment	Docker, CI/CD	Automates deployment & scaling

🚀 Deployment Guide

1️⃣ Clone the Repository

git clone /~https://github.com/ChainElect/chain-elect-infra.git
cd chain-elect-infra

2️⃣ Set Up Terraform

cd terraform
terraform init
terraform validate
terraform apply -auto-approve

3️⃣ Set Up Ansible

cd ansible
ansible-playbook -i inventory.ini setup.yaml

4️⃣ Verify Deployment • Check DigitalOcean Dashboard to confirm infrastructure is running. • Use terraform output to get public IPs.

🔐 Environment Variables

•	Check DigitalOcean Dashboard to confirm infrastructure is running.
•	Use terraform output to get public IPs.

Before running Terraform, ensure you have the required secrets in GitHub Actions or your local environment:

export TF_VAR_do_token="your-digitalocean-api-token"
export TF_VAR_ssh_key_fingerprint="your-ssh-key-fingerprint"

🔄 Continuous Deployment (CI/CD)

•	GitHub Actions automatically applies Terraform changes when updates are pushed.
•	Docker images are built and deployed using CI/CD workflows.
