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:
- https://github.com/gabrieldemarmiesse/python-on-whales - to automate the docker configuration and start
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
Compatibility test
docker 2>&1 | grep compose
compose* Docker Compose (Docker Inc., 2.0.0-beta.1)
Installation of Docker Compose V2 CLI
see https://github.com/WolfgangFahl/pymediawikidocker/blob/main/scripts/install
docker --version
cliplugindir=$HOME/.docker/cli-plugins
mkdir -p $cliplugindir
cd $cliplugindir
wget https://github.com/docker/compose-cli/releases/download/v2.0.0-beta.3/docker-compose-linux-amd64
mv docker-compose-linux-amd64 docker-compose
chmod +x docker-compose
# check result
ls -l
docker
docker 2>&1 | grep compose
via pip
pip install pymediawikidocker
# alternatively if your pip is not a python3 pip
pip3 install pymediawikidocker
upgrade
pip install pymediawikidocker -U
# alternatively if your pip is not a python3 pip
pip3 install pymediawikidocker -U
Usage
usage: mwcluster.py [-h] [-d] [-V] [-vl [VERSIONS ...]] [-bp BASEPORT] [-sp SQLPORT] [-mv MARIADBVERSION] [-f]

optional arguments:
-h, --help show this help message and exit
-d, --debug set debug level [default: False]
-V, --version show program's version number and exit
-vl [VERSIONS ...], --versionList [VERSIONS ...]
-bp BASEPORT, --basePort BASEPORT
-sp SQLPORT, --sqlBasePort SQLPORT
-mv MARIADBVERSION, --mariaDBVersion MARIADBVERSION
-f, --forceRebuild shall the applications rebuild be forced (with stop and remove of existing containers)

Bash into docker containers
# Mediawiki container
docker exec -it mw1_36_0_mw_1 /bin/bash
# MariaDB container
docker exec -it mw1_36_0_db_1 /bin/bash
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)
docker stop $(docker ps -aq)
docker rm $(docker ps -aq)
