README for the Docker-Based System Administration Project

---

Project Overview

This project focuses on system administration using Docker, where you will virtualize multiple Docker images within your personal virtual machine. The goal is to create a small infrastructure composed of different services that follow specific rules.

Project Structure

• Preamble: Brief introduction and overview of the project.
• Introduction: Expands on the project's objective to enhance your system administration skills via Docker.
• General Guidelines: Key requirements and setup instructions.
• Mandatory Part: Detailed tasks and configurations required for the core infrastructure.
• Bonus Part: Additional tasks for enhancing the project (only evaluated if the mandatory part is perfect).
• Submission and Peer-Evaluation: Instructions on how to submit your project for evaluation.

General Guidelines

1. Virtual Machine: The entire project must be completed in a VM.
2. Folder Structure:
   • All necessary configuration files should be placed in a srcs folder.
   • A Makefile must be at the root of your directory to set up the entire application.
3. Docker Usage:
   • You must create Docker images manually (no pulling ready-made images, except for Alpine/Debian).
   • Services must run in dedicated containers.
   • Containers should restart automatically in case of crashes.

Mandatory Part

1. Infrastructure Setup:

   • Use Docker Compose to manage the containers.
   • Create containers for NGINX (with TLSv1.2 or TLSv1.3 only), WordPress with php-fpm, and MariaDB.
   • Set up two volumes: one for the WordPress database and one for the website files.
   • Ensure containers communicate via a dedicated Docker network.
   • Configure a domain name that points to your local IP (e.g., yourlogin.42.fr).

2. Security & Best Practices:

   • No hard-coded passwords in Dockerfiles; use environment variables and .env files.
   • Follow best practices for writing Dockerfiles (no infinite loops, proper usage of PID 1, etc.).
   • The NGINX container should be the only entry point via port 443.

Bonus Part

Additional tasks include setting up Redis cache, an FTP server, a static website, Adminer, or any other useful service. These will be evaluated only if the mandatory part is perfect.

---

Submission Guidelines

Submit your project via your Git repository. Ensure that all files are correctly named and placed as required.
