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.

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.

Prerequisites

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'
services:
  mariadb:
    image: 'bitnami/mariadb:latest'
    environment:
      - ALLOW_EMPTY_PASSWORD=yes
      - MARIADB_USER=bn_mediawiki
      - MARIADB_DATABASE=bitnami_mediawiki
    volumes:
      - 'mariadb_data:/bitnami'
  mediawiki:
    image: 'bitnami/mediawiki:1'
    labels:
      kompose.service.type: nodeport
    environment:
      - MARIADB_HOST=mariadb
      - MARIADB_PORT_NUMBER=3306
      - MEDIAWIKI_DATABASE_USER=bn_mediawiki
      - MEDIAWIKI_DATABASE_NAME=bitnami_mediawiki
      - ALLOW_EMPTY_PASSWORD=yes
    ports:
      - '80:80'
      - '443:443'
    volumes:
      - 'mediawiki_data:/bitnami'
    depends_on:
      - mariadb
volumes:
  mariadb_data:
    driver: local
  mediawiki_data:
    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:

Create a new network for the application and the database:

$ docker network create mediawiki-tier

Create a volume for MariaDB persistence and create a MariaDB container

$ docker volume create --name mariadb_data
$ docker run -d --name mariadb \
  -e ALLOW_EMPTY_PASSWORD=yes \
  -e MARIADB_USER=bn_mediawiki \
  -e MARIADB_DATABASE=bitnami_mediawiki \
  --net mediawiki-tier \
  --volume mariadb_data:/bitnami \
  bitnami/mariadb:latest

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

Create volumes for MediaWiki persistence and launch the container

$ docker volume create --name mediawiki_data
$ docker run -d --name mediawiki -p 80:80 -p 443:443 \
  -e ALLOW_EMPTY_PASSWORD=yes \
  -e MEDIAWIKI_DATABASE_USER=bn_mediawiki \
  -e MEDIAWIKI_DATABASE_NAME=bitnami_mediawiki \
  --net mediawiki-tier \
  --volume mediawiki_data:/bitnami \
  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'

services:
  mariadb:
    image: 'bitnami/mariadb:latest'
    environment:
      - ALLOW_EMPTY_PASSWORD=yes
      - MARIADB_USER=bn_mediawiki
      - MARIADB_DATABASE=bitnami_mediawiki
    volumes:
      - '/path/to/mariadb-persistence:/bitnami'
  mediawiki:
    image: 'bitnami/mediawiki:latest'
    depends_on:
      - mariadb
    ports:
      - '80:80'
      - '443:443'
    environment:
      - MEDIAWIKI_DATABASE_USER=bn_mediawiki
      - MEDIAWIKI_DATABASE_NAME=bitnami_mediawiki
      - ALLOW_EMPTY_PASSWORD=yes
    volumes:
      - '/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:

Create a network (if it does not exist):

$ docker network create mediawiki-tier

Create a MariaDB container with host volume:

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

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

Run the Mediawiki container:

$ docker run -d --name mediawiki -p 80:80 -p 443:443 \
  -e ALLOW_EMPTY_PASSWORD=yes \
  -e MEDIAWIKI_DATABASE_USER=bn_mediawiki \
  -e MEDIAWIKI_DATABASE_NAME=bitnami_mediawiki \
  --net mediawiki-tier \
  --volume /path/to/mediawiki-persistence:/bitnami \
  bitnami/mediawiki:latest

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 https://github.com/bitnami/bitnami-docker-mariadb/blob/master/README.md#upgrade-this-image

Get the updated images:

$ docker pull bitnami/mediawiki:latest

Stop your container

For docker-compose: $ docker-compose stop mediawiki
For manual execution: $ docker stop mediawiki

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.

Remove the currently running container

For docker-compose: $ docker-compose rm -v mediawiki
For manual execution: $ docker rm -v mediawiki

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

Configuration

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:

mediawiki:
  image: bitnami/mediawiki:latest
  ports:
    - 80:80
    - 443:443
  environment:
    - 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 \
  bitnami/mediawiki:latest

      - ALLOW_EMPTY_PASSWORD=yes
      - SMTP_HOST=ssl://smtp.gmail.com
      - SMTP_HOST_ID=mydomain.com
      - SMTP_PORT=465
      - SMTP_USER=your_email@gmail.com
      - SMTP_PASSWORD=your_password

For manual execution:

$ docker run -d --name mediawiki -p 80:80 -p 443:443 \
  -e MEDIAWIKI_DATABASE_USER=bn_mediawiki \
  -e MEDIAWIKI_DATABASE_NAME=bitnami_mediawiki \
  -e SMTP_HOST=ssl://smtp.gmail.com \
  -e SMTP_HOST_ID=mydomain.com \
  -e SMTP_PORT=465 \
  -e SMTP_USER=your_email@gmail.com \
  -e SMTP_PASSWORD=your_password \
  --net mediawiki-tier \
  --volume /path/to/mediawiki-persistence:/bitnami \
  bitnami/mediawiki:latest

How to install imagemagick in the Bitnami MediaWiki Docker image

If you require better quality thumbnails for your uploaded images, you may want to install imagemagick instead of using GD. To do so you can build your own docker image adding the imagemagick system package.

Create the following Dockerfile

FROM bitnami/mediawiki:latest
RUN install_packages imagemagick

Build the docker image

$ docker build -t bitnami/mediawiki:imagemagick .

Edit the docker-compose.yml to use the docker image built in the previous step.
Finally exec into your MediaWiki container and edit the file /opt/bitnami/mediawiki/LocalSettings.php as described here in order to start using imagemagick.

How to migrate from a Bitnami Mediawiki Stack

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

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

Copy the backup files to your TARGET installation:

$ scp ~/backup-mediawiki-* YOUR_USERNAME@TARGET_HOST:~

Create the Mediawiki Container as described in the section How to use this Image (Using Docker Compose)
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 ...

Stop Apache:

$ docker-compose exec mediawiki nami stop apache

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'

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

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 -'

Fix Mediawiki directory permissions:

$ docker-compose exec mediawiki chown -R daemon:daemon /bitnami/mediawiki

Restart Apache:

$ docker-compose exec mediawiki nami start apache
