Setting up MediaWiki using Docker Compose and Mariadb
Back to Homepage
PREFACE - I am going to assume that you already have a server/PC with Linux installed. You will also need Docker and Docker-Compose installed
I found it a little hard to setup MediaWiki for the first time using Docker and getting all the database working correctly. I have now run a few instances of it and decided to write a short post on getting it working
1 - First we need to create our directory. For this test we will be using /home/john/docker/testwiki
2 - Inside this folder we need to create a file named docker-compse.yml and copy the following into it
<syntaxhighlight line> version: '3'
services:
mediawiki:
image: mediawiki
restart: always
ports:
- 4820:80
links:
- database
volumes:
- /home/john/docker/testwiki/images:/var/www/html/images
# After initial setup, download LocalSettings.php to the same directory as
# this yaml and uncomment the following line and use compose to restart
# the mediawiki service
#- /home/john/docker/testwiki/LocalSettings.php:/var/www/html/LocalSettings.php
# This key also defines the name of the database host used during setup instead of the default "localhost"
database:
image: mariadb
restart: always
ports:
- 4840:3306
environment:
# @see https://phabricator.wikimedia.org/source/mediawiki/browse/master/includes/DefaultSettings.php
MYSQL_DATABASE: testwikidb
MYSQL_USER: testwikiuser
MYSQL_PASSWORD: testwikipassword
MYSQL_RANDOM_ROOT_PASSWORD: 'yes'
