# AWS CI/CD Infrastructure Automation with Multi-Environment Support

This project implements a **CI/CD pipeline with AWS CLI & Bash scripting**.  

It provisions infrastructure and configures pipelines for **multi-environment deployment** (QC and Production).

## Features

- **Infrastructure as Code (IaC)**

  - VPC with subnets (public & private), internet gateway, route tables.

  - Security Groups with SSH & self-referencing rules.

  - IAM Roles & Policies for EC2, CodeDeploy, CodePipeline.

  - Auto Scaling Group with EC2 Launch Template & scaling policies.

  - Network Load Balancer (NLB) + Route53 DNS records.

  - SSH Key managed in **AWS Secrets Manager**.

- **CI/CD Pipeline**

  - Source: CodeCommit (branch-based triggers).

  - Build: CodeBuild project with buildspec.

  - Deploy: CodeDeploy application with in-place deployment.

  - Pipeline: CodePipeline (Source → Build → Deploy).

- **Automation**

  - `deploy.sh` orchestrates provisioning for QC or Prod.

  - EC2 installs runtime + CodeDeploy agent.

  - `AfterInstall` creates **systemd service** for app runtime.

## Project Structure

├── autoscalinggroup.sh # Launch Template, Auto Scaling Group,Target Group, Listener  

├── dns.sh # Route53 DNS records  

├── deploy.sh # Orchestrator (QC/Prod configs + infra provisioning)  

├── security.sh # SSH key, Secrets Manager, Security Group  

├── conf-prod.sh # Production environment configuration  

├── conf-qc.sh # QC environment configuration  

├── vpc.sh # VPC, Subnets, Internet Gateway, Route Tables  

├── build.sh # CodeBuild project setup  

└── README.md # Documentation

## Scripts Execution Order (handled by deploy.sh)

VPC → Security → Auto Scaling → DNS

## Pipeline Flow

Push code → CodeCommit triggers → CodeBuild builds → CodeDeploy deploys → EC2 Auto Scaling instances + Route53 DNS.
