Multi-Platform AWS ECR CI/CD Pipeline for Cloud Applications

A production-grade multi-platform CI/CD pipeline implementation that automatically builds, pushes, and deploys containerized applications across development, staging, and production environments using GitHub Actions, Amazon ECR/EC2, NGINX reverse proxy, and SSL automation.

Live Production: adelekeadebowale.com — Production environment 🚀
Live Staging: staging.adelekeadebowale.com — Staging environment 🔧
Live Development: dev.adelekeadebowale.com — Development environment 💻

✨ All environments are live and operational! This project demonstrates enterprise-level DevOps practices with complete environment isolation, automated SSL management, subdomain routing, and production deployment strategies that mirror real-world cloud infrastructure implementations.

Project Overview

This advanced CI/CD pipeline automatically deploys containerized applications across three isolated environments (development, staging, production) using separate GitHub Actions workflows, dedicated Docker containers, and subdomain-based routing. The implementation showcases:

Multi-Platform Architecture: Complete isolation between dev, staging, and production environments
Automated Branch-Based Deployments: Each environment deploys from its dedicated Git branch
SSL-Secured Subdomains: Full HTTPS implementation across all environments with Let's Encrypt
NGINX Reverse Proxy: Intelligent subdomain routing to appropriate container ports
Container Orchestration: Multiple containers running simultaneously on a single EC2 instance
Production-Grade Security: Comprehensive secrets management and secure deployment practices

Multi-Platform Architecture

The pipeline implements a sophisticated multi-platform deployment strategy:

GitHub Branches → GitHub Actions → Docker Tags → ECR → EC2 Containers → NGINX → Subdomains

Port Allocation Strategy

Each environment runs on a dedicated port to prevent conflicts:

Production: localhost:3000 → adelekeadebowale.com
Staging: localhost:3001 → staging.adelekeadebowale.com
Development: localhost:3002 → dev.adelekeadebowale.com

Getting Started

Prerequisites

Before setting up the pipeline, ensure you have:

AWS Account with ECR and EC2 access
Domain Name with DNS management (Route 53 recommended)
GitHub Repository with appropriate permissions
EC2 Instance running Ubuntu 20.04 or later
Basic understanding of Docker, NGINX, and SSL concepts

Step 1: Create Git Branch Structure

# Clone your repository
git clone https://github.com/bowale01/Multi-Platform-CICD-Workflow.git
cd Multi-Platform-CICD-Workflow

# Create long-lived branches
git checkout -b develop
git push -u origin develop

git checkout -b staging
git push -u origin staging

# main branch should already exist
git checkout main

Step 2: Set Up AWS Infrastructure

2.1 Create ECR Repository

# Login to AWS
aws configure

# Create ECR repository
aws ecr create-repository \
    --repository-name your-app-name \
    --region your-region

# Note the repository URI (you'll need this for GitHub Secrets)

2.2 Launch EC2 Instance

Launch Ubuntu 20.04 LTS instance
Configure security group:
- SSH (22) from your IP
- HTTP (80) from anywhere
- HTTPS (443) from anywhere
Download and save the SSH key pair (.pem file)
Note the public IP address

2.3 Configure DNS Records

In your DNS provider (Route 53 recommended), create these A records:

adelekeadebowale.com           A    [YOUR-EC2-IP]
www.adelekeadebowale.com       A    [YOUR-EC2-IP]
staging.adelekeadebowale.com   A    [YOUR-EC2-IP]
dev.adelekeadebowale.com       A    [YOUR-EC2-IP]

Step 3: Configure EC2 Instance

SSH into your EC2 instance and run the setup script:

# SSH into EC2
ssh -i your-key.pem ubuntu@your-ec2-ip

# Clone your repository
git clone https://github.com/bowale01/Multi-Platform-CICD-Workflow.git
cd Multi-Platform-CICD-Workflow

# Make scripts executable
chmod +x scripts/*.sh

# Run initial setup
./scripts/ec2-setup.sh

# Log out and log back in for Docker group changes
exit
ssh -i your-key.pem ubuntu@your-ec2-ip

Step 4: Configure AWS CLI on EC2

# Configure AWS credentials on EC2
aws configure
# Enter your AWS Access Key ID
# Enter your AWS Secret Access Key
# Enter your default region
# Enter default output format (json)

Step 5: Deploy NGINX Configurations

# Navigate to repository directory
cd ~/Multi-Platform-CICD-Workflow

# Deploy NGINX configurations
sudo ./scripts/deploy-nginx.sh

Step 6: Provision SSL Certificates

Important: Edit the provision-ssl.sh script first and replace your-email@example.com with your actual email address.

# Edit the script
nano scripts/provision-ssl.sh
# Update the email address in all certbot commands

# Run SSL provisioning
sudo ./scripts/provision-ssl.sh

Step 7: Configure GitHub Secrets

In your GitHub repository, go to Settings → Secrets and variables → Actions, and add these secrets:

Secret Name	Description	Example Value
`AWS_ACCESS_KEY_ID`	AWS IAM access key	`AKIAIOSFODNN7EXAMPLE`
`AWS_SECRET_ACCESS_KEY`	AWS IAM secret key	`wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY`
`AWS_REGION`	AWS region	`us-east-1`
`ECR_REGISTRY`	ECR registry URL	`123456789012.dkr.ecr.us-east-1.amazonaws.com`
`ECR_REPOSITORY`	ECR repository name	`your-app-name`
`EC2_PUBLIC_IP`	EC2 public IP	`54.123.45.67`
`EC2_SSH_PRIVATE_KEY`	EC2 SSH private key	Contents of your .pem file

Step 8: Test the Pipeline

Test Development Environment

# Switch to develop branch
git checkout develop

# Make a change
echo "# Development Test" >> test.txt
git add test.txt
git commit -m "Test dev deployment"
git push origin develop

# Check GitHub Actions tab for workflow progress
# Visit https://dev.adelekeadebowale.com when complete

Test Staging Environment

# Switch to staging branch
git checkout staging

# Merge from develop
git merge develop
git push origin staging

# Visit https://staging.adelekeadebowale.com when complete

Test Production Environment

# Switch to main branch
git checkout main

# Merge from staging
git merge staging
git push origin main

# Visit https://adelekeadebowale.com when complete

Workflow Details

Production Workflow (deploy-prod.yml)

Triggers on push to main branch:

Checks out code
Configures AWS credentials
Builds Docker image with :latest tag
Pushes to ECR
SSHs into EC2 and deploys to port 3000
Container name: app-prod

Staging Workflow (deploy-staging.yml)

Triggers on push to staging branch:

Checks out code
Configures AWS credentials
Builds Docker image with :staging tag
Pushes to ECR
SSHs into EC2 and deploys to port 3001
Container name: app-staging

Development Workflow (deploy-dev.yml)

Triggers on push to develop branch:

Checks out code
Configures AWS credentials
Builds Docker image with :dev tag
Pushes to ECR
SSHs into EC2 and deploys to port 3002
Container name: app-dev

Container Management

Use the provided management script for common operations:

# Show status of all containers
./scripts/manage-containers.sh status

# View logs for specific environment
./scripts/manage-containers.sh logs prod
./scripts/manage-containers.sh logs staging
./scripts/manage-containers.sh logs dev

# Restart containers
./scripts/manage-containers.sh restart prod
./scripts/manage-containers.sh restart all

# Health check all environments
./scripts/manage-containers.sh health

# Clean up Docker resources
./scripts/manage-containers.sh cleanup

Troubleshooting

Issue: Container not starting

# Check container logs
docker logs app-prod
docker logs app-staging
docker logs app-dev

# Check if port is already in use
sudo netstat -tulpn | grep :3000
sudo netstat -tulpn | grep :3001
sudo netstat -tulpn | grep :3002

Issue: SSL certificate errors

# Test NGINX configuration
sudo nginx -t

# Check certificate status
sudo certbot certificates

# Manually renew certificates
sudo certbot renew --dry-run

Issue: GitHub Actions deployment fails

Verify all GitHub Secrets are correctly set
Check EC2 security group allows SSH from GitHub Actions IPs
Verify AWS credentials have ECR push permissions
Check EC2 instance has enough disk space: df -h

Issue: Domain not resolving

# Test DNS resolution
nslookup adelekeadebowale.com
nslookup staging.adelekeadebowale.com
nslookup dev.adelekeadebowale.com

# Check NGINX is running
sudo systemctl status nginx

# Check NGINX configuration
sudo nginx -t

Security Best Practices

Never commit secrets to the repository
Use GitHub Secrets for all sensitive data
Regularly rotate AWS access keys
Keep EC2 instance updated: sudo apt update && sudo apt upgrade
Monitor SSL expiration (Certbot handles renewal automatically)
Use security groups to restrict EC2 access
Enable AWS CloudWatch for monitoring
Implement backup strategy for production data
