Docker Compose Production Setup

version: '3'

services:
  php:
    image: sylius/sylius-php:latest
    environment:
      - APP_ENV=prod
      - DATABASE_URL=mysql://sylius:password@db/sylius
    volumes:
      - sylius_public:/srv/sylius/public
    restart: always

  nginx:
    image: sylius/sylius-nginx:latest
    ports:
      - "80:80"
    depends_on:
      - php
    volumes:
      - sylius_public:/srv/sylius/public
    restart: always

  db:
    image: mysql:8
    environment:
      - MYSQL_USER=sylius
      - MYSQL_PASSWORD=password
      - MYSQL_DATABASE=sylius
    volumes:

Kubernetes Production Deployment (Recommended)

# Deploy PHP-FPM and Nginx sidecars or as separate services
kubectl create deployment sylius --image=your-custom-sylius-image:latest
kubectl expose deployment sylius --port=80

• Zero-Downtime Updates: Use rolling deployments for safe updates and security patches.
• Elastic Scaling: Scale your PHP-FPM workers automatically based on traffic peaks.
• Persistent Storage: Use PVCs to manage your public/media folder across multiple pods.

Scaling Strategy

• Faceted Search: Offload complex product searches to a dedicated Elasticsearch or Algolia instance.
• Database Optimization: Use read-replicas for catalog browsing and ensure heavy indexes are optimized.
• Object Storage: Always move your /media folder to S3 or a compatible provider in production.
• Session Clustering: Use Redis for sessions to ensure users stay logged in as they move between web pods.

Backup & Safety

• SQL Backups: Automate nightly database dumps and store them securely offsite.
• Media Backups: Ensure your S3 bucket has versioning and cross-region replication.
• Monitoring: Use a tool like New Relic or Sentry to track performance bottlenecks and errors.
• HTTPS Everywhere: Force SSL/TLS for all traffic via your Nginx or ingress controller.
