Deployment Guide

Prerequisites

• Docker 20.10+ and Docker Compose 1.29+
• Node.js 18+ and npm 9+ (for building)
• Access to a cloud provider (AWS/GCP/Azure)
• Domain name (optional but recommended)

Production Deployment

1. Server Setup

Recommended Server Requirements

• 2+ CPU cores
• 4GB+ RAM
• 20GB+ disk space
• Ubuntu 22.04 LTS

Initial Server Setup

# Update system
sudo apt update && sudo apt upgrade -y

# Install required packages
sudo apt install -y git curl htop ufw

# Configure firewall
sudo ufw allow OpenSSH
sudo ufw allow http
sudo ufw allow https
sudo ufw enable

2. Install Docker

# Install Docker
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

# Add current user to docker group
sudo usermod -aG docker $USER

# Install Docker Compose
sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

3. Deploy Application

# Clone repository
git clone https://github.com/DevOpsTerminal/text2iac.git
cd text2iac

# Copy and configure environment variables
cp .env.example .env
nano .env  # Edit with your configuration

# Build and start containers
make build
make start

4. Configure Reverse Proxy (Nginx)

1. Install Nginx:

   sudo apt install -y nginx
   

2. Create Nginx configuration:

   sudo nano /etc/nginx/sites-available/text2iac
   

   server {
       listen 80;
       server_name your-domain.com;
   
       location / {
           proxy_pass http://localhost:8080;
           proxy_http_version 1.1;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection 'upgrade';
           proxy_set_header Host $host;
           proxy_cache_bypass $http_upgrade;
       }
   
       location /api {
           proxy_pass http://localhost:3000;
           proxy_http_version 1.1;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection 'upgrade';
           proxy_set_header Host $host;
           proxy_cache_bypass $http_upgrade;
       }
   }
   

3. Enable the site:

   sudo ln -s /etc/nginx/sites-available/text2iac /etc/nginx/sites-enabled/
   sudo nginx -t
   sudo systemctl restart nginx
   

5. Set Up SSL (Let’s Encrypt)

# Install Certbot
sudo apt install -y certbot python3-certbot-nginx

# Obtain SSL certificate
sudo certbot --nginx -d your-domain.com

# Test automatic renewal
sudo certbot renew --dry-run

Environment Variables

Variable	Required	Description	Default
NODE_ENV	No	Node environment	production
PORT	No	API server port	3000
OPENAI_API_KEY	Yes	OpenAI API key
JWT_SECRET	Yes	JWT secret key
DATABASE_URL	Yes	Database connection URL
REDIS_URL	No	Redis connection URL	redis://redis:6379

Scaling

Horizontal Scaling

1. API Service:

   # docker-compose.yml
   api:
     image: text2iac/api:latest
     deploy:
       replicas: 3
       resources:
         limits:
           cpus: '0.5'
           memory: 1G
   

2. Load Balancing:
   • Use a load balancer (AWS ALB, Nginx, Traefik)
   • Configure sticky sessions if needed

Database

For production, consider using managed database services:

• AWS RDS
• Google Cloud SQL
• Azure Database

Monitoring

Logging

# View logs
docker-compose logs -f

# Set up log rotation
sudo nano /etc/logrotate.d/docker

Metrics

• Prometheus for metrics collection
• Grafana for visualization
• Sentry for error tracking

Backup

1. Database Backup:

   # Create backup
   docker-compose exec -T db pg_dump -U postgres text2iac > backup.sql
   
   # Restore
   cat backup.sql | docker-compose exec -T db psql -U postgres text2iac
   

2. Volume Backup:

   # Create backup
   tar -czf data_backup.tar.gz /var/lib/docker/volumes/text2iac_*
   

Maintenance

Updating

git pull
docker-compose build --no-cache
docker-compose up -d --force-recreate

Health Checks

# Check container status
docker ps

# Check logs
docker-compose logs -f

# Check disk usage
df -h

Troubleshooting

Common Issues

1. Port Conflicts:
   • Check if ports 80, 443, 3000 are in use
   • Use netstat -tuln | grep <port> to check
2. Docker Issues:

   # Restart Docker
   sudo systemctl restart docker
   
   # Check container logs
   docker logs <container_id>
   

3. Database Connection Issues:
   • Verify database URL in .env
   • Check if database is running: docker-compose ps db
