Usage

With MySQL

See Docker Compose example.

Start a MySQL container.

docker run --name=mediawiki_mysql \
-e MYSQL_DATABASE=wikidb \
-e MYSQL_USER=wikiuser \
-e MYSQL_PASSWORD=mysecret \
-e MYSQL_RANDOM_ROOT_PASSWORD=1 \
-v /var/mediawiki/mysql:/var/lib/mysql \
-d mysql:5.7

Start MediaWiki container.

docker run --name mediawiki_wiki \
--link mediawiki_mysql:mediawiki_mysql \
-p 8080:8080 \
-e MEDIAWIKI_SERVER=http://localhost:8080 \
-e MEDIAWIKI_SITENAME=MyWiki \
-e MEDIAWIKI_LANGUAGE_CODE=en \
-e MEDIAWIKI_DB_TYPE=mysql \
-e MEDIAWIKI_DB_HOST=mediawiki_mysql \
-e MEDIAWIKI_DB_PORT=3306 \
-e MEDIAWIKI_DB_NAME=wikidb \
-e MEDIAWIKI_DB_USER=wikiuser \
-e MEDIAWIKI_DB_PASSWORD=mysecret \
-e MEDIAWIKI_ENABLE_UPLOADS=1 \
-v /var/mediawiki/images:/images \
-d credija/mediawiki

Create a new database with the install script. Insert username and password for your admin account.

docker exec -it mediawiki_wiki /script/install.sh <username> <password>

If you are using an existing database run the update script instead.

docker exec -it mediawiki_wiki /script/update.sh

Copy the secret key that the install script dumps or find the variable $wgSecretKey in your previous LocalSettings.php file and put it into an environment variable.

-e MEDIAWIKI_SECRET_KEY=secretkey

If you are using an existing database find the variable $wgDBTableOptions in your previous LocalSettings.php file and put it into an environment variable.

-e MEDIAWIKI_DB_TABLE_OPTIONS=ENGINE=InnoDB, DEFAULT CHARSET=binary

You should be able to browse your wiki at http://localhost:8080.

With SQLite

See Docker Compose example.

Start MediaWiki container.

docker run --name=mediawiki_wiki \
-p 8080:8080 \
-e MEDIAWIKI_SERVER=http://localhost:8080 \
-e MEDIAWIKI_SITENAME=MyWiki \
-e MEDIAWIKI_LANGUAGE_CODE=en \
-e MEDIAWIKI_DB_TYPE=sqlite \
-e MEDIAWIKI_DB_NAME=wikidb \
-e MEDIAWIKI_ENABLE_UPLOADS=1 \
-v /var/mediawiki/images:/images \
-v /var/mediawiki/data:/data \
-d credija/mediawiki

Create a new database with the install script. Insert username and password for your admin account.

docker exec -it mediawiki_wiki /script/install.sh <username> <password>

If you are using an existing database run the update script instead.

docker exec -it mediawiki_wiki /script/update.sh

Copy the secret key that the install script dumps or find the variable $wgSecretKey in your previous LocalSettings.php file and put it into an environment variable.

-e MEDIAWIKI_SECRET_KEY=secretkey

You should be able to browse your wiki at http://localhost:8080.

Configuration

General

Set the mandatory environment variables:

• Set MEDIAWIKI_SERVER to your wiki's primary domain, prefixed with the primary protocol.
• Set MEDIAWIKI_SITENAME to your wiki's name.
• Set MEDIAWIKI_LANGUAGE_CODE to a language code of this list.

-e MEDIAWIKI_SERVER=http://wiki.example.com \
-e MEDIAWIKI_SITENAME=MyWiki \
-e MEDIAWIKI_LANGUAGE_CODE=en

Uploads

To enable file uploads set the environment variable MEDIAWIKI_ENABLE_UPLOADS to 1.

-e MEDIAWIKI_ENABLE_UPLOADS=1

Mount a writable volume to the images folder.

-v /var/mediawiki/images:/images

Which file extensions are allowed for uploading can be controlled with the environment variable MEDIAWIKI_FILE_EXTENSIONS.

-e MEDIAWIKI_FILE_EXTENSIONS=png,gif,jpg,jpeg,webp,pdf

The maximum size for file uploads can be controlled with the environment variable MEDIAWIKI_MAX_UPLOAD_SIZE.

-e MEDIAWIKI_MAX_UPLOAD_SIZE=100M

E-Mail

SMTP E-Mail can be enabled by setting MEDIAWIKI_SMTP to 1. TLS auth will be used by default.

-e MEDIAWIKI_SMTP=1
-e MEDIAWIKI_SMTP_HOST=smtp.example.com
-e MEDIAWIKI_SMTP_IDHOST=example.com
-e MEDIAWIKI_SMTP_PORT=587
-e MEDIAWIKI_SMTP_AUTH=1
-e MEDIAWIKI_SMTP_USERNAME=mail@example.com
-e MEDIAWIKI_SMTP_PASSWORD=secret

Using a self-signed certificate will not work because of failing peer verification. If you know the security implications you can disable peer verification by setting MEDIAWIKI_SMTP_SSL_VERIFY_PEER to 0.

Logo

You can setup your own logo by mounting a PNG file.

-v ./var/mediawiki/logo.png:/var/www/mediawiki/resources/assets/wiki.png:ro

Skins

You can change the default skin by setting the environment variable MEDIAWIKI_DEFAULT_SKIN.

-e MEDIAWIKI_DEFAULT_SKIN=vector

The default skins are packaged with the container:

• vector

You can add more skins by mounting them.

-v ./var/mediawiki/skins/Vector:/var/www/mediawiki/skins/Vector:ro

HTTPS

HTTPS is not longer supported by the container itself. Its recommended to use a proxy container for HTTPS setups.

Make sure that you set the MEDIAWIKI_SERVER environment variable to the outside URL of your wiki and to apply the https prefix.

-e MEDIAWIKI_SERVER=https://localhost

Extensions

You can add more extensions by mounting them.

-v ./var/mediawiki/extensions/MyOtherExtension:/var/www/mediawiki/extensions/MyOtherExtension:ro

Additional configuration

You can add own PHP configuration values by mounting an additional configuration file that is loaded at the end of the generic configuration file.

-v /var/mediawiki/ExtraLocalSettings.php:/var/www/mediawiki/ExtraLocalSettings.php:ro

A good starting point is to copy the file that's inside the container. You can display its content with the following command.

docker exec -it mediawiki_wiki cat /var/www/mediawiki/ExtraLocalSettings.php

Configuration file

Beside the docker like configuration with environment variables you still can use your own full LocalSettings.php file.

However this will make all environment variables unusable except MEDIAWIKI_HTTPS and MEDIAWIKI_SMTP_SSL_VERIFY_PEER.

-v /var/mediawiki/LocalSettings.php:/var/www/mediawiki/LocalSettings.php:ro

Performance

The container has some performance related configuration options. If you have more advanced needs you can override the configuration inside the container by mounting configuration files.

The number of PHP-FPM worker processes can be configured with the environment variables PHPFPM_WORKERS_START, PHPFPM_WORKERS_MIN and PHPFPM_WORKERS_MAX.

-e PHPFPM_WORKERS_START=10
-e PHPFPM_WORKERS_MIN=10
-e PHPFPM_WORKERS_MAX=20

Default for start and min is 1. Default for max is 20, so up to 20 worker processes will be spawned dynamically when needed.

For a more advanced configuration of PHP-FPM mount a configuration file to /usr/local/etc/php-fpm.conf.

-v /var/mediawiki/php-fpm.conf:/usr/local/etc/php-fpm.conf:ro

The number of Parsoid worker processes can be configured with the environment variable PARSOID_WORKERS.

-e PARSOID_WORKERS=10

Default is 1. Please note that the number of Parsoid workers is not managed dynamically. Make sure that you spawn enough workers for your requirements.

For a more advanced configuration of Parsoid mount a configuration file to /usr/lib/parsoid/src/config.yaml.

-v /var/mediawiki/config.yaml:/usr/lib/parsoid/src/config.yaml:ro

Configuration reference

Below is a list of all environment variables supported by the container.

When using an own LocalSettings.php file according to the section "Configuration file" most variables be unusable.
