Motivation

Official Mediawiki docker images are available for the different Mediawiki versions.

These images need additional infrastructure to create useable Mediawiki environments. The goal of this project is to semi-automatically create such environments and test the functionality. Python was choosen as a development environment for the libraries that are needed and available to perform the tasks:

python on whales was chosen over:

Since it works on the command line interface and not via the SDK and supports docker compose.

How it works

The core concept is a "MediawikiCluster" that is a set of docker applications that run MediaWiki instances with varying versions of MediaWiki and the underlying database.

Installation

Prerequisites

Docker on Windows, Mac or Linux suppporting "docker compose up" using the Docker composer V2 CLI

# Enable raw html in for the wiki
docker exec  mw1_35_3-mw-1 sh -c "echo '\$wgRawHtml = true;\n' >> /var/www/html/LocalSettings.php"

No space left on device issue

e.g. when starting mariadb container see https://stackoverflow.com/questions/37645879/how-can-i-fix-docker-mac-no-space-left-on-device-error

Wiki Backup

The passwords are available from the docker files e.g. 

grep PASS docker-compose.yml 
      MYSQL_PASSWORD: "TnbKf2zGRmZPjUvz7B"
      MYSQL_ROOT_PASSWORD: "QWehnR9yLMY7YAb9pw"

In a docker bash a dump can be created 

mysqldump wiki -u wikiuser --password=TnbKf2zGRmZPjUvz7B > /tmp/wiki.sql

and then copied to your local machine 

docker cp mw1_36_0_db_1:/tmp/wiki.sql /tmp

Stop and Remove all running containers

These commands will stop and remove all running docker containers (not only the ones created pymediawikidocker/the mwcluster command) 

# kill/stop all running containers
docker kill $(docker ps -q)
#docker stop $(docker ps -aq)
# remove all docker containers
docker rm $(docker ps -aq)

Recreate Clean docker state

# remove all images
docker rmi $(docker images -q)
