Framework-Specific Deployment Patterns

Docker Multi-Stage Production Build:

# docker-compose.production.yml
version: '3.8'
services:
  php:
    image: framework-php:production
    environment:
      APP_ENV: production
      APP_DEBUG: false
    volumes:
      - ./src:/var/www/html/src:ro
      - ./public:/var/www/html/public:ro
    networks:
      - app-network
    healthcheck:
      test: ["CMD", "php", "console.php", "health:check"]
      interval: 30s
      timeout: 10s
      retries: 3
      
  nginx:
    image: nginx:alpine
    ports:
      - "443:443"
      - "80:80"
    volumes:
      - ./docker/nginx/production.conf:/etc/nginx/conf.d/default.conf:ro
      - ./ssl:/etc/ssl/certs:ro
    depends_on:
      - php
    networks:
      - app-network

Environment Validation Script:

#!/bin/bash
# validate-production-env.sh

# Check required environment variables
REQUIRED_VARS=(
    "DB_PASSWORD"
    "APP_ENV"
    "SHOPIFY_WEBHOOK_SECRET"
)

echo "🔍 Validating production environment..."

for var in "${REQUIRED_VARS[@]}"; do
    if [[ -z "${!var}" || "${!var}" == *"*** REQUIRED ***"* ]]; then
        echo "❌ Missing or placeholder value for: $var"
        exit 1
    fi
done

# Test database connection
php console.php db:ping || {
    echo "❌ Database connection failed"
    exit 1
}

# Test framework health
php console.php framework:health-check || {
    echo "❌ Framework health check failed" 
    exit 1
}

echo "✅ Production environment validation passed"

Zero-Downtime Deployment Strategy:

#!/bin/bash
# zero-downtime-deploy.sh

# 1. Build new version in parallel
echo "🔄 Building new version..."
docker build -t app:new-version .

# 2. Health check new version
echo "🏥 Health checking new version..."
docker run --rm app:new-version php console.php health:check

# 3. Database migrations (if needed)
echo "📊 Running migrations..."
docker run --rm --env-file .env app:new-version php console.php db:migrate

# 4. Switch traffic (Blue-Green)
echo "🔄 Switching traffic..."
docker-compose -f docker-compose.blue-green.yml up -d --scale app-green=0
docker-compose -f docker-compose.blue-green.yml up -d --scale app-blue=0 --scale app-green=1

# 5. Verify new version
echo "✅ Verifying deployment..."
curl -f https://localhost/health || {
    echo "❌ Health check failed, rolling back..."
    docker-compose -f docker-compose.blue-green.yml up -d --scale app-blue=1 --scale app-green=0
    exit 1
}

echo "🚀 Deployment completed successfully"

Security Best Practices

SSL and HTTPS Configuration:

# nginx production configuration
server {
    listen 443 ssl http2;
    server_name your-domain.com;
    
    ssl_certificate /etc/ssl/certs/fullchain.pem;
    ssl_certificate_key /etc/ssl/certs/privkey.pem;
    
    # Security headers for framework
    add_header X-Frame-Options "SAMEORIGIN" always;
    add_header X-Content-Type-Options "nosniff" always;
    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
    
    # Framework-specific routing
    location / {
        try_files $uri $uri/ /index.php$is_args$args;
    }
    
    location ~ \.php$ {
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
        
        # Framework requires User-Agent
        fastcgi_param HTTP_USER_AGENT $http_user_agent;
    }
}

Production Environment Security:

# Security hardening checklist
- [ ] No hardcoded secrets in code
- [ ] Strong database passwords 
- [ ] SSL certificates properly configured
- [ ] Firewall rules configured
- [ ] Regular security updates
- [ ] Log monitoring enabled
- [ ] Access controls implemented
- [ ] Backup encryption enabled

Monitoring and Observability

Framework Health Monitoring:

// Framework provides health check endpoint
php console.php health:check

// Monitoring integration
php console.php metrics:export --format=prometheus

Log Aggregation Setup:

# docker-compose.logging.yml
version: '3.8'
services:
  app:
    logging:
      driver: "json-file"
      options:
        max-size: "10m"
        max-file: "3"
        labels: "service=framework"
        
  log-aggregator:
    image: fluent/fluent-bit
    volumes:
      - ./logs/fluent-bit.conf:/fluent-bit/etc/fluent-bit.conf
      - /var/lib/docker/containers:/var/lib/docker/containers:ro

Performance Optimization

Production Optimizations:

• OPcache: Enabled with optimal settings for framework
• Asset Optimization: Vite production build with compression
• Database: Connection pooling and query optimization
• Caching: Framework cache implementation with Redis
• CDN Integration: Static asset delivery optimization

Resource Monitoring:

# Performance monitoring
docker stats
docker exec php php console.php performance:report
docker exec nginx nginx -t && nginx -s reload

Backup and Recovery

Automated Backup Strategy:

#!/bin/bash
# backup-production.sh

# Database backup
docker exec mysql mysqldump -u root -p$DB_ROOT_PASSWORD --all-databases > backup-$(date +%Y%m%d).sql

# Application backup
tar -czf app-backup-$(date +%Y%m%d).tar.gz \
    --exclude=node_modules \
    --exclude=.git \
    --exclude=vendor \
    .

# Upload to secure storage
# rsync backups to remote storage

Recovery Procedures:

1. Database Recovery: Point-in-time recovery from backups
2. Application Rollback: Git-based version rollback with deployment
3. Configuration Recovery: Environment and config restoration
4. Service Recovery: Container orchestration and health verification

CI/CD Integration

GitHub Actions Workflow:

# .github/workflows/deploy.yml
name: Production Deployment

on:
  push:
    branches: [ main ]

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      
      - name: Validate Environment
        run: ./scripts/validate-production-env.sh
        
      - name: Run Tests
        run: ./vendor/bin/pest
        
      - name: Build Assets
        run: |
          npm ci
          npm run build
          
      - name: Deploy to Production
        run: ./deploy.sh
        env:
          DEPLOY_KEY: ${{ secrets.DEPLOY_KEY }}

Your expertise ensures that deployments are secure, reliable, and maintainable while leveraging the framework's built-in capabilities for monitoring, health checking, and performance optimization.
