Short Description
Bitnami Docker Image for MediaWiki
Full Description

What is Mediawiki?

MediaWiki is an extremely powerful, scalable software and a feature-rich wiki implementation that uses PHP to process and display data stored in a database, such as MySQL.

Pages use MediaWiki's wikitext format, so that users without knowledge of XHTML or CSS can edit them easily.


Docker Compose

$ curl -sSL > docker-compose.yml
$ docker-compose up -d


WARNING: This is a beta configuration, currently unsupported.

Get the raw URL pointing to the kubernetes.yml manifest and use kubectl to create the resources on your Kubernetes cluster like so:

$ kubectl create -f

Why use Bitnami Images?

  • Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
  • With Bitnami images the latest bug fixes and features are available as soon as possible.
  • Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
  • Bitnami images are built on CircleCI and automatically pushed to the Docker Hub.
  • All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading linux distribution.


To run this application you need Docker Engine 1.10.0. It is recommended that you use Docker Compose version 1.6.0 or later.

How to use this image

Run Mediawiki with a Database Container

Running Mediawiki with a database server is the recommended way. You can either use docker-compose or run the containers manually.

Run the application using Docker Compose

This is the recommended way to run Mediawiki. You can use the following docker compose template:

version: '2'
    image: 'bitnami/mariadb:latest'
      - 'mariadb_data:/bitnami'
    image: 'bitnami/mediawiki:latest'
      - '80:80'
      - '443:443'
      - 'mediawiki_data:/bitnami'
      - mariadb
    driver: local
    driver: local

Run the application manually

If you want to run the application manually instead of using docker-compose, these are the basic steps you need to run:

  1. Create a new network for the application and the database:

    $ docker network create mediawiki-tier
  2. Start a MariaDB database in the network generated:

    $ docker run -d --name mariadb -e ALLOW_EMPTY_PASSWORD=yes --net mediawiki-tier bitnami/mariadb:latest

    Note: You need to give the container a name in order for Mediawiki to resolve the host

  3. Run the Mediawiki container:

    $ docker run -d -p 80:80 -p 443:443 --name mediawiki --net mediawiki-tier bitnami/mediawiki:latest

Then you can access your application at http://your-ip/

Persisting your application

If you remove the container all your data and configurations will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.

For persistence you should mount a volume at the /bitnami path. Additionally you should mount a volume for persistence of the MariaDB data.

The above examples define docker volumes namely mariadb_data and mediawiki_data. The MediaWiki application state will persist as long as these volumes are not removed.

To avoid inadvertent removal of these volumes you can mount host directories as data volumes. Alternatively you can make use of volume plugins to host the volume data.

Mount host directories as data volumes with Docker Compose

This requires a minor change to the docker-compose.yml template previously shown:

version: '2'

    image: 'bitnami/mariadb:latest'
      - '/path/to/mariadb-persistence:/bitnami'
    image: 'bitnami/mediawiki:latest'
      - mariadb
      - '80:80'
      - '443:443'
      - '/path/to/mediawiki-persistence:/bitnami'

Mount host directories as data volumes using the Docker command line

In this case you need to specify the directories to mount on the run command. The process is the same than the one previously shown:

  1. Create a network (if it does not exist):

    $ docker network create mediawiki-tier
  2. Create a MariaDB container with host volume:

    $ docker run -d --name mariadb -e ALLOW_EMPTY_PASSWORD=yes \
     --net mediawiki-tier \
     --volume /path/to/mariadb-persistence:/bitnami \

    Note: You need to give the container a name in order to Mediawiki to resolve the host

  3. Run the Mediawiki container:

    $ docker run -d --name mediawiki -p 80:80 -p 443:443 \
     --net mediawiki-tier \
     --volume /path/to/mediawiki-persistence:/bitnami \

Upgrade this application

Bitnami provides up-to-date versions of MariaDB and Mediawiki, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container. We will cover here the upgrade of the Mediawiki container. For the MariaDB upgrade see

  1. Get the updated images:

    $ docker pull bitnami/mediawiki:latest
  2. Stop your container

    • For docker-compose: $ docker-compose stop mediawiki
    • For manual execution: $ docker stop mediawiki
  3. Take a snapshot of the application state

$ rsync -a /path/to/mediawiki-persistence /path/to/mediawiki-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)

Additionally, snapshot the MariaDB data

You can use these snapshots to restore the application state should the upgrade fail.

  1. Remove the currently running container

    • For docker-compose: $ docker-compose rm -v mediawiki
    • For manual execution: $ docker rm -v mediawiki
  2. Run the new image

    • For docker-compose: $ docker-compose start mediawiki
    • For manual execution (mount the directories if needed): docker run --name mediawiki bitnami/mediawiki:latest


Environment variables

When you start the mediawiki image, you can adjust the configuration of the instance by passing one or more environment variables either on the docker-compose file or on the docker run command line. If you want to add a new environment variable:

  • For docker-compose add the variable name and value under the application section:
  image: bitnami/mediawiki:latest
    - 80:80
    - 443:443
    - MEDIAWIKI_PASSWORD=my_password
  • For manual execution add a -e option with each variable and value:

    $ docker run -d --name mediawiki -p 80:80 -p 443:443 \
     -e MEDIAWIKI_PASSWORD=my_password \
     --net mediawiki-tier \
     --volume /path/to/mediawiki-persistence:/bitnami \

Available variables:

  • MEDIAWIKI_USERNAME: Mediawiki application username. Default: user
  • MEDIAWIKI_PASSWORD: Mediawiki application password. Default: bitnami1
  • MEDIAWIKI_EMAIL: Mediawiki application email. Default:
  • MEDIAWIKI_WIKI_NAME: Mediawiki wiki name. Default: Bitnami MediaWiki
  • MARIADB_USER: Root user for the MariaDB database. Default: root
  • MARIADB_PASSWORD: Root password for the MariaDB.
  • MARIADB_HOST: Hostname for MariaDB server. Default: mariadb
  • MARIADB_PORT_NUMBER: Port used by MariaDB server. Default: 3306

SMTP Configuration

To configure Mediawiki to send email using SMTP you can set the following environment variables:

  • SMTP_HOST: SMTP host.
  • SMTP_PORT: SMTP port.
  • SMTP_USER: SMTP account user.
  • SMTP_PASSWORD: SMTP account password.

This would be an example of SMTP configuration using a GMail account:

  • docker-compose:
    image: bitnami/mediawiki:latest
      - 80:80
      - 443:443
      - SMTP_HOST=ssl://
      - SMTP_PORT=465
      - SMTP_PASSWORD=your_password
  • For manual execution:

    $ docker run -d --name mediawiki -p 80:80 -p 443:443 \
     -e SMTP_HOST=ssl:// \
     -e \
     -e SMTP_PORT=465 \
     -e \
     -e SMTP_PASSWORD=your_password \
     --net mediawiki-tier \
     --volume /path/to/mediawiki-persistence:/bitnami \

How to migrate from a Bitnami Mediawiki Stack

You can follow these steps in order to migrate it to this container:

  1. Export the data from your SOURCE installation: (assuming an installation in /opt/bitnami directory)

    $ mysqldump -u root -p bitnami_mediawiki > ~/backup-mediawiki-database.sql
    $ gzip -c ~/backup-mediawiki-database.sql > ~/backup-mediawiki-database.sql.gz
    $ cd /opt/bitnami/apps/mediawiki/htdocs/
    $ tar cfz ~/backup-mediawiki-extensions.tar.gz extensions
    $ tar cfz ~/backup-mediawiki-images.tar.gz images
    $ tar cfz ~/backup-mediawiki-skins.tar.gz skins
  2. Copy the backup files to your TARGET installation:

    $ scp ~/backup-mediawiki-* YOUR_USERNAME@TARGET_HOST:~
  3. Create the Mediawiki Container as described in the section How to use this Image (Using Docker Compose)

  4. Wait for the initial setup to finish. You can follow it with

    $ docker-compose logs -f mediawiki

    and press Ctrl-C when you see this:

    nami    INFO  mediawiki successfully initialized
    Starting mediawiki ...
  5. Stop Apache:

    $ docker-compose exec mediawiki nami stop apache
  6. Obtain the password used by Mediawiki to access the database in order avoid reconfiguring it:

    $ docker-compose exec mediawiki bash -c 'cat /opt/bitnami/mediawiki/LocalSettings.php | grep wgDBpassword'
  7. Restore the database backup: (replace ROOT_PASSWORD below with your MariaDB root password)

    $ cd ~
    $ docker-compose exec mariadb mysql -u root -pROOT_PASSWORD
    $ MariaDB [(none)]> drop database bitnami_mediawiki;
    $ MariaDB [(none)]> create database bitnami_mediawiki;
    $ MariaDB [(none)]> grant all privileges on bitnami_mediawiki.* to 'bn_mediawiki'@'%' identified by 'PASSWORD_OBTAINED_IN_STEP_6';
    $ MariaDB [(none)]> exit
    $ gunzip -c ./backup-mediawiki-database.sql.gz | docker exec -i $(docker-compose ps -q mariadb) mysql -u root bitnami_mediawiki -pROOT_PASSWORD
  8. Restore extensions/images/skins directories from backup:

    $ cat ./backup-mediawiki-extensions.tar.gz | docker exec -i $(docker-compose ps -q mediawiki) bash -c 'cd /bitnami/mediawiki/ ; tar -xzvf -'
    $ cat ./backup-mediawiki-images.tar.gz | docker exec -i $(docker-compose ps -q mediawiki) bash -c 'cd /bitnami/mediawiki/ ; tar -xzvf -'
    $ cat ./backup-mediawiki-skins.tar.gz | docker exec -i $(docker-compose ps -q mediawiki) bash -c 'cd /bitnami/mediawiki/ ; tar -xzvf -'
  9. Fix Mediawiki directory permissions:

    $ docker-compose exec mediawiki chown -R daemon:daemon /bitnami/mediawiki
  10. Restart Apache:

    $ docker-compose exec mediawiki nami start apache
