🗣 About

This project aims to broaden your knowledge of system administration by using Docker. You will virtualize several Docker images, creating them in your new personal virtual machine.

🛠 Usage

How to run

  • Have Docker Desktop installed and running
  • Add the line 127.0.0.1 arabenst.42.fr to /etc/hosts to redirect the required domain name to localhost
  • be inside the root folder of the repo and run make up to start
  • visit arabenst.42.fr in your browser
  • run make down to stop

Upload wordpress backup

Because newer versions of the plugin get stuck on upload...

  • visit arabenst.42.fr/wp-admin enter the admin login as in srcs/.env
  • install the All-in-One Migration Version 6.7 Wordpress plugin following this guide
  • navigate to the plugin, select Import and upload the desired backup (inception.wpress is the website I made for the evaluation)
  • visit the main page again and the changes should be applied

💬 Description

  • Three Docker Containers run the individual services:
    • nginx (webserver)
    • MariaDB (database)
    • WordPress (content management system) and php-fpm (web tool for quicker website)
  • Two Docker Volumes mount local directories for persisting files:
    • WordPress database
    • WordPress website files
  • A Docker Network establishes the connection between your containers

  • Each container is launched from a Docker Image which is built from a Dockerfile:
    • pulls a base image (I decided to only use Alpine, as it's more light-weight and therefore installs quicker than Debian)
    • installs and configures programs as required
    • launches a startup-script that makes some last minute setup and runs the service
  • A docker-compose.yml file manages everything:
    • builds images from Dockerfiles (importing the .env file as the environment)
    • launches containers from images
    • hooks the containers up with volumes
    • configures the network for the containers to communicate with each other
