Inception is a System Administration project at 42 School that focuses on Docker containerization.
The goal is to set up a small infrastructure composed of different services under specific rules using Docker Compose.

• ✨ Requirements
• 🛠️ Services
• 📂 Directory Structure
• ⚙️ Configuration
• 🐛 Troubleshooting

Before starting, ensure the following are installed:

• 🐳 Docker
• ⚙️ Docker Compose
• 📦 Containers
• 💾 Volumes
• 🌐 Network

Here are the main services you will set up:

• 🌐 NGINX: Web server with SSL/TLS support.
• 📝 WordPress: CMS with php-fpm.
• 💾 MariaDB: Database server.

Bonus Services:

• 🔄 Redis: Caching system.
• 📡 FTP server: File transfer protocol server.
• 🖼️ Static website: Simple static HTML site.
• 📊 Adminer: Managing contents of MySQL databases.

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

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]
