What is MediaWiki?
MediaWiki is free and open-source wiki software. Originally developed by Magnus Manske and improved by Lee Daniel Crocker, it runs on many websites, including Wikipedia, Wiktionary and Wikimedia Commons. It is written in the PHP programming language and stores the contents into a database. Like WordPress, which is based on a similar licensing and architecture, it has become the dominant software in its category.
How to use this image
The basic pattern for starting a
mediawiki instance is:
$ docker run --name some-mediawiki -d mediawiki
If you’d like to be able to access the instance from the host without the container’s IP, standard port mappings can be used:
$ docker run --name some-mediawiki -p 8080:80 -d mediawiki
Then, access it via
http://host-ip:8080 in a browser.
There are multiple database types supported by this image, most easily used via standard container linking. In the default configuration, SQLite can be used to avoid a second container and write to flat-files. More detailed instructions for different (more production-ready) database types follow.
When first accessing the webserver provided by this image, it will go through a brief setup process. The details provided below are specifically for the “Set up database” step of that configuration process.
$ docker run --name some-mediawiki --link some-mysql:mysql -d mediawiki
- Database type:
MySQL, MariaDB, or equivalent
- Database name/username/password:
<details for accessing your MySQL instance>(
MYSQL_DATABASE; see environment variables in the description for
- ADVANCED OPTIONS; Database host:
some-mysql(for using the
/etc/hostsentry added by
--linkto access the linked container’s MySQL instance)
By default, this image does not include any volumes.
/var/www/html/LocalSettings.php are things that generally ought to be volumes, but do not explicitly have a
VOLUME declaration in this image because volumes cannot be removed.
$ docker run --rm mediawiki tar -cC /var/www/html/sites . | tar -xC /path/on/host/sites
docker stack deploy or
# MediaWiki with MariaDB # # Access via "http://localhost:8080" # (or "http://$(docker-machine ip):8080" if using docker-machine) version: '3' services: mediawiki: image: mediawiki restart: always ports: - 8080:80 links: - database volumes: - /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 # - ./LocalSettings.php:/var/www/html/LocalSettings.php database: image: mariadb restart: always environment: # @see https://phabricator.wikimedia.org/source/mediawiki/browse/master/includes/DefaultSettings.php MYSQL_DATABASE: my_wiki MYSQL_USER: wikiuser MYSQL_PASSWORD: example MYSQL_RANDOM_ROOT_PASSWORD: yes
docker stack deploy -c stack.yml mediawiki (or
docker-compose -f stack.yml up), wait for it to initialize completely, and visit
http://host-ip:8080 (as appropriate).
Adding additional libraries / extensions
This image does not provide any additional PHP extensions or other libraries, even if they are required by popular plugins. There are an infinite number of possible plugins, and they potentially require any extension PHP supports. Including every PHP extension that exists would dramatically increase the image size.
If you need additional PHP extensions, you’ll need to create your own image
FROM this one. The documentation of the
php image explains how to compile additional extensions.
The following Docker Hub features can help with the task of keeping your dependent images up-to-date:
- Automated Builds let Docker Hub automatically build your Dockerfile each time you push changes to it.
- Repository Links can ensure that your image is also rebuilt any time
