This project is a hands-on introduction to system administration, containerization, and virtualization. The goal of this project is to create a fully functional multi-container infrastructure using Docker Compose running in a Virtual Machine to simulate a real-world development environment.

The Docker-based environment hosts these services:

• Nginx: A web server to handle HTTP/HTTPS requests
• MariaDB: A database to store and manage application data
• WordPress: A content management system, demonstrating a real-world application setup

Mentioning some key features:

• Containerization: Each service is encapsulated within its own Docker container, ensuring portability and consistency across environments
• Orchestration: Use of Docker Compose to define and manage multi-container setups
• Networking: Secure communication between services via properly configured networks and ports
• Virtualization: Deployment on a Virtual Machine to replicate real-world infrastructure
• Persistence: Ensuring data persistence across container restarts for services like MariaDB and WordPress

I used VirtualBox for the choice of Virtual Machine for this project, though I am not running in inside a VM in the GIF.

This was my third to last project studying in Hive Helsinki. On this project, I gained valuable experience in managing Docker containers, creating modular, reusable, and scalable Docker Compose configurations and understanding container networking and security best practices. I actually finished this project in mid 2024, but I wanted to redo the commit history and make some minor changes.

• Containerization
• Service orchestration
• Networking
• Virtualization
• Web server configuration
• Database management
• Content management systems
• Data persistence
• Security
• Automation
• System administration

• Shell
• YAML
• Docker Compose
• Dockerfile
• Makefile

First make sure you have Docker Compose installed on your system. You can just install Docker Desktop, it should include Docker Compose. Read more about it here.

1. git clone https://github.com/kenlies/42inception
2. cd 42inception
3. make
4. Use your favourite browser to navigate to https://inception.42.fr

The code documentation/comments can be improved. Also more useful services like Redis could've been added.
