Inception

A Docker-based WordPress infrastructure project that sets up a complete development environment using multiple containers and services.

🎯 Project Overview

This project involves setting up a small infrastructure composed of different services using Docker containers. The entire setup is designed to run in a virtual machine, with each service running in its own dedicated container.

🔧 Technical Requirements

• Virtual Machine environment
• Docker and Docker Compose
• Make

📦 Services

The infrastructure includes the following services, each running in its own container:

1. NGINX

   • Configured with TLSv1.2 or TLSv1.3 only
   • Acts as the only entry point (port 443)

2. WordPress + php-fpm

   • WordPress installation with php-fpm configuration
   • Runs without nginx in its own container

3. MariaDB

   • Database service
   • Runs in a dedicated container

💾 Volumes

The project uses two Docker volumes:

1. WordPress database volume
2. WordPress website files volume

Volumes are mounted in /home/login/data on the host machine.

🌐 Networking

• Custom Docker network for inter-container communication
• Domain configuration: login.42.fr pointing to local IP
• No use of network: host, --link, or links:

🔐 Security Features

• TLS encryption (v1.2 or v1.3)
• Environment variables for sensitive data
• No hardcoded passwords in Dockerfiles
• WordPress admin username restrictions (cannot contain admin/Admin or administrator/Administrator)

🚀 Getting Started

1. Clone the repository
2. Create a .env file in the srcs directory with required environment variables
3. Run make to build and start the infrastructure

Environment Variables

Create a srcs/.env file with the following variables:

DOMAIN_NAME=your_login.42.fr
CERTS_=./path_to_certificates
MYSQL_ROOT_PASSWORD=your_root_password
MYSQL_USER=your_username
MYSQL_PASSWORD=your_password

📝 Additional Notes

• Containers are configured to restart automatically in case of crashes
• No infinite loops or hacky patches (tail -f, bash, sleep infinity, etc.)
• Latest tag is prohibited in Docker images
• Images must be built from either Alpine or Debian (penultimate stable version)

🎉 Bonus Features

• Redis cache for WordPress
• FTP server container
• Static website (non-PHP)
• Adminer
• Additional useful service (must be justified)

⚠️ Important Reminders

• Don't commit sensitive data or credentials
• Keep .env file in .gitignore
• Ensure all services are properly configured before deployment
• Follow Docker best practices for daemon processes and PID 1
