⚙️ Configuration

Key configuration files:

• .env: Environment variables
• docker-compose.yml: Service definitions
• srcs/requirements/*/Dockerfile: Individual service configurations
• srcs/requirements/*/conf/*: Service-specific configuration files

Important environment variables:

• DOMAIN_NAME: Your domain name
• MYSQL_ROOT_PASSWORD: MariaDB root password
• MYSQL_USER: MariaDB user
• MYSQL_PASSWORD: MariaDB user password
• WORDPRESS_DB_NAME: WordPress database name

🐛 Troubleshooting

1. Containers not starting:

   • Check logs: docker-compose logs
   • Verify port availability

2. WordPress not connecting to database:

   • Ensure MariaDB is fully initialized
   • Check database credentials in WordPress configuration

3. SSL certificate issues:

   • Verify SSL certificate generation in NGINX container
   • Check NGINX configuration for proper SSL setup

For more detailed troubleshooting, refer to individual service logs: docker-compose logs [service_name]
