Docker Compose file showing how to install plugins in the official MediaWiki image

Installation

Install Docker

Install Docker according to the official instruction.

Configure database usernames and password

The database usernames and passwords aren't stored in this repository, so you'll have to create the file which contain them yourself. First create the file mysql_secrets with the following, replacing the text in square brackets with what ever you want:

MYSQL_DATABASE=[mysql_database]
MYSQL_USER=[mysql_username]
MYSQL_PASSWORD="[mysql_password]"

Then create the file mediawiki_secrets with the following, replacing the text in square brackets so it matches the contents of mysql_secrets.

<?php
$wgDBname = "[mysql_database]";
$wgDBuser = "[mysql_username]";
$wgDBpassword = "[mysql_password]";

Create a MediaWiki image with the plugins you need

The file mediawiki/Dockerfile adds the plugins I use to the official MediaWiki docker image. Turn this into a usable image using the following:

$ docker build -t divinenephron/mediawiki mediawiki

Start MediaWiki and the services it needs

docker-compose.yml contain instructions for launching the divinenephron/mediawiki image created above along with the other containers it needs to work. Together these containers are called a "stack".

Start the stack using:

$ docker swarm init
$ docker stack deploy -c docker-compose.yml my-mediawiki

Stop the stack using:

$ docker stack rm my-mediawiki
$ docker swarm leave --force
