Inception

This project aims to expand its knowledge of system administration using Docker. It requires the virtualization of several Docker images by creating them in a virtual machine (VM).

Project overview

Inception is the first containerisation project within the core curriculum of 42 School.

It is a logical extension of Born2beroot, a project which aims to discover virtual machines, networking and system administration.

The objective is to create a Docker network which contains the following 3 services:

Nginx, a web server that must be recreated through ‘Webserv’ (another 42 School project),
MariaDB, an open source relational database based on MySQL,
WordPress, a content management system (CMS).

In order to develop as many skills as possible, I have also set up the following 5 services:

Redis Cache, which optimises WordPress performances by keeping database queries in memory,
A FTP server, allowing to manipulate files related to the WordPress folder,
A static website in HTML,
Adminer, a minimalist database management interface contained in a single PHP file,
Grafana, an open source analysis and monitoring tool connected to Redis Cache and MariaDB services.

This project enables to develop multiple skills, such as:

Building Docker images by creating Dockerfiles from scratch,
Centralised management of services, volumes and network using the ‘docker-compose.yml’ file,
Using Nginx's reverse proxy to redirect external URLs to an internal service.

This list is not exhaustive.
