MediaWiki is a free and open-source wiki app, used to power wiki websites such as Wikipedia, Wiktionary and Commons, developed by the Wikimedia Foundation and others.
docker run --name some-mediawiki --link some-mysql:mysql -v /local/data/path:/data:rw -d wikimedia/mediawiki
Partial explanation of arguments:
--linkallows you to connect this container with a database container. SeeConfigure Databasebelow for more details.-vis used to mount a shared folder with the container. SeeShared Volumebelow for more details.
Having troubling accessing your MediaWiki server? See Accessing MediaWiki below for help.
Use the following environmental variables to generate a LocalSettings.php and perform automatic installation of MediaWiki. If you don't include these, you'll need to go through the installation wizard. See Installation Wizard below for more details. Please see Manual:Configuration_settings for details about what these configuration variables do.
-e MEDIAWIKI_SITE_SERVER=(required set this to the server host and include the protocol (and port if necessary) likehttp://my-wiki:8080; configures$wgServer)-e MEDIAWIKI_SITE_NAME=(defaults toMediaWiki; configures$wgSitename)-e MEDIAWIKI_SITE_LANG=(defaults toen; configures$wgLanguageCode)-e MEDIAWIKI_ADMIN_USER=(defaults toadmin; configures default administrator username)-e MEDIAWIKI_ADMIN_PASS=(defaults torosebud; configures default administrator password)-e MEDIAWIKI_UPDATE=true(defaults tofalse; runphp maintenance/update.php)-e MEDIAWIKI_SLEEP=(defaults to0; delays startup of container, useful when using Docker Compose)
As mentioned, this will generate the LocalSettings.php file that is required by MediaWiki. If you mounted a shared volume (see Shared Volume below), the generated LocalSettings.php will be automatically moved to your share volume allowing you to edit it. If a CustomSettings.php file exists in your data file, a require('/data/CustomSettings.php'); will be appended to the generated LocalSettings.php file.
We currently track latest MediaWiki production branches, as run on wikipedia.org.
wikimedia/mediawiki:latest(currently uses1.27-wmf9)
To use one of these pre-built containers, simply specify the tag as part of the docker run command:
docker run --name some-mediawiki --link mysql -v /local/data/path:/data:rw -d wikimedia/mediawiki
See https://github.com/gwicke/mediawiki-containers for a fully-featured docker compose setup with VisualEditor & other services.
The example above uses --link to connect the MediaWiki container with a running mysql container. This is probably not the best idea for use in production, keeping data in docker containers can be dangerous.
You can use Postgres instead of MySQL as your database server using the :postgres tag:
docker run --name some-mediawiki --link some-postgres:postgres -v /local/data/path:/data:rw -d wikimedia/mediawiki:postgres
You can use the following environment variables for connecting to another database server:
-e MEDIAWIKI_DB_TYPE=...(defaults tomysql, but can also bepostgres)-e MEDIAWIKI_DB_HOST=...(defaults to the address of the linked database container)-e MEDIAWIKI_DB_PORT=...(defaults to the port of the linked database container or to the default for specified db type)-e MEDIAWIKI_DB_USER=...(defaults torootorpostgresbased on db type beingmysql, orpostgresrespsectively)-e MEDIAWIKI_DB_PASSWORD=...(defaults to the password of the linked database container)-e MEDIAWIKI_DB_NAME=...(defaults tomediawiki)-e MEDIAWIKI_DB_SCHEMA... (defaults tomediawiki, applies only to when using postgres)
If the MEDIAWIKI_DB_NAME specified does not already exist on the provided MySQL
server, it will be created automatically upon container startup, provided
that the MEDIAWIKI_DB_USER specified has the necessary permissions to create
it.
To use with an external database server, use MEDIAWIKI_DB_HOST (along with
MEDIAWIKI_DB_USER and MEDIAWIKI_DB_PASSWORD if necessary):
docker run --name some-mediawiki \
-e MEDIAWIKI_DB_HOST=10.0.0.1
-e MEDIAWIKI_DB_PORT=3306 \
-e MEDIAWIKI_DB_USER=app \
-e MEDIAWIKI_DB_PASSWORD=secure \
wikimedia/mediawiki
If provided mount a shared volume using the -v argument when running docker run, the mediawiki container will automatically look for a LocalSettings.php file and images, skins and extensions folders. When found symbolic links will be automatically created to the respsective file or folder to replace the ones included with the default MediaWiki install. This allows you to easily configure (LocalSettings.php), backup uploaded files (images), and customize (skins and extensions) your instance of MediaWiki.
It is highly recommend you mount a shared volume so uploaded files and images will be outside of the docker container.
By default the shared volume must be mounted to /data on the container, you can change this using by using -e MEDIAWIKI_SHARED=/new/data/path.
Additionally if a composer.lock and a composer.json are detected, the container will automatically download composer and run composer install. Composer can be used to install additional extensions, skins and dependencies.
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 using the -p or -P argument when running docker run. See docs.docker.com for more help.
docker run --name some-mediawiki --link some-mysql:mysql -p 8080:80 -v /local/data/dir:data:rw -d wikimedia/mediawiki
Then, access it via http://localhost:8080 or http://host-ip:8080 in a browser.
The first time you access your new MediaWiki instance, you'll be navigated through an installation wizard. The purpose of which is to setup the default database and to generate a configuration file, LocalSettings.php.
After using the installation wizard, save a copy of the generated LocalSettings.php to your data volume (-v /local/data/dir:/data:rw).
If you're using --link to connect with a database, you'll be requested to specify the database host, user, password and name. Run exec some-mediawiki printenv | grep 'MYSQL\|DB\|POSTGRES' to view the environmental variables relating to the linked database. The database user will not be included, for that use root or postgres depending on whether you're using mysql or postgres respsectively.
If you're using Docker Machine, using http://localhost:8080 won't work, instead you'll need to run:
docker-machine ip default
And access your instance of MediaWiki at:
http://$(docker-machine ip default):8080/
If you're using boot2docker, using http://localhost:8080 won't work, instead you'll need to run:
boot2docker ip
And access your instance of MediaWiki at:
http://$(boot2docker ip):8080/
To enable SSL on your server, place your certificate files inside your mounted share volume as ssl.key, ssl.crt and ssl.bundle.crt. Then add -e MEDIAWIKI_ENABLE_SSL=true to your docker run command. This will enable the ssl module for Apache and force your instance of mediawik to SSL-only, redirecting all requests from port 80 (http) to 443 (https). Also be sure to include -P or -p 443:443 in your docker run command.
Note When enabling SSL, you must update the $wgServer in your LocalSettings.php to include https:// as the prefix. If using automatic install, update the MEDIAWIKI_SITE_SERVER environmental variable.
