Inception

Introduction

The Inception project is part of the curriculum at School 42 and focuses on learning the fundamentals of virtualization and containerization. The project is designed to give students hands-on experience with Docker, Docker Compose, and system architecture while guiding them through the process of setting up and managing a multi-container Docker environment for a web application.

Learnings

Understand and utilize containerization with Docker.
Learn to use Docker Compose to orchestrate multi-container applications.
Explore the concept of Infrastructure as Code.
Gain familiarity with setting up services in a containerized environment.
Understand basic networking between Docker containers.
Basics of Nginx, Wordpress and Databases

Mandatory Part

Requirements

You will need to create a multi-container environment using Docker and Docker Compose that includes the following services:

Nginx: A web server that will act as a reverse proxy for the web application.
WordPress: A CMS (Content Management System) for building and managing websites.
MariaDB: A database service to store WordPress data.
Volumes: Persistent storage for your services to retain data between container restarts.
Networking: Configure Docker networks to ensure proper communication between services.

Specifications

Each service (Nginx, WordPress, MariaDB) must run in its own Docker container.
You must create a Docker Compose file (docker-compose.yml) to define and configure the services.
Containers must be configured to restart automatically if they crash.
Data stored by MariaDB and WordPress should be stored on volumes to ensure persistence.
The containers must be orchestrated and networked so that they communicate properly with each other.
You must expose the necessary ports on Nginx and Wordpress to allow external access to the web application and database interface.

How to Run the Project

Prerequisites

Install Docker: Docker Installation Guide
Install Docker Compose: Docker Compose Installation Guide
Make sure your system has enough resources (e.g., CPU, memory, and storage) to run the services simultaneously.

Step-by-Step Instructions

Clone the Repository:
Clone the project repository to your local machine.

git clone https://github.com/yourusername/inception.git
cd inception/srcs

Configure Environment Variables: Create a .env file or use the default values within the docker-compose.yml file. You may need to set database passwords, network configurations, or other environment-specific variables. There is an example .env file in the root of this repository.
Build Docker Images: Build the Docker images for each service by running:
```
docker-compose build
```
Start the Services: Bring up all services by running:
```
docker-compose up -d
```
Access the Web Application: Visit http://localhost:8080 in your web browser to access the WordPress site. Visit http://localhost:8080/admin to access The admin page.
Manage Services: You can stop the services with:
```
docker-compose down
```
