inception

One container is not enough, we need to go deeper

🗣 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
