Notes and configuration files for setting up MediaWiki in a dockerized environment.

This guide is comprised of two methods for building a dockerized MediaWiki site:

  • From the official MediaWiki docker image - easiest for beginners and those who just want to stand up a site (simple)
  • From scratch - allows you to tweak the image more from the start and can be more complicated (advanced)

Regardless of the method used, this guide will also include any extensions you have in the build/extensions folder.

Preparation

There are two setups available:

  • One for Intranet use that doesn't use a proxy or SSL.
  • One for Internet use that uses NGINX as a proxy and Let's Encrypt for SSL.

Intranet - no proxy

  • Create /srv/wiki, /srv/wiki/build, and /srv/wiki/build/extensions directories.

Internet

  • Create /srv/wiki, /srv/wiki/build, /srv/wiki/build/extensions, and /srv/nginx-proxy directories.

Installation

Choose the type of installation that matches the one used in the preparation section above.

Intranet - no proxy

Use this if on an Intranet with no Internet access. If this becomes a heavily used site then consider putting this behind a proxy.

MediaWiki

Copy the following to /srv/wiki/docker-compose.yml 

version: '3'
services:
  web:
    image: mediawiki
    build: build/.
    container_name: wiki
    depends_on: 
      - database
       ## parsoid is bundled as part of 1.35+, only uncomment if using an older version
       #- parsoid
    restart: always
    ports:
      - 80:80
    links:
      - database
    volumes:
      - /srv/wiki/html/images:/var/www/html/images
      ## TODO: remove the # below AFTER you have downloaded the LocalSettings.php file
      #- /srv/wiki/LocalSettings.php:/var/www/html/LocalSettings.php
  database:
    image: mariadb
    container_name: db
    restart: always
    environment:
      MYSQL_DATABASE: mediawiki
      ## TODO: Change the password below
      MYSQL_USER: wikiuser
      ## TODO: Change the password below
      MYSQL_PASSWORD: wiki
      MYSQL_ROOT_PASSWORD: changeme
    volumes:
      - /srv/wiki/db:/var/lib/mysql
   
  ## parsoid is bundled as part of 1.35+, only uncomment if using an older version
  #parsoid:
  #  image: thenets/parsoid:0.10
  #  container_name: parsoid
  #  restart: always
  #  environment:
  #   - PARSOID_NUM_WORKERS=0
  #    - PARSOID_DOMAIN_wiki=http://web/api.php

Internet

For an Internet setup you will use NGINX-Proxy with Let's Encrypt for SSL certificates.

NGINX-Proxy

  • Copy the following to /srv/nginx-proxy/docker-compose.yml
version: '2'
services:
  nginx-proxy:
    image: jwilder/nginx-proxy
    container_name: nginx-proxy
    environment:
      - "HTTPS_METHOD=noredirect"
    labels:
      - "com.github.jrcs.letsencrypt_nginx_proxy_companion.nginx_proxy"
    ports:
      - "80:80"
      - "443:443"
    restart: always
    volumes:
      - "./data/etc/certs:/etc/nginx/certs"
      - "./data/etc/nginx/vhost.d:/etc/nginx/vhost.d"
      - "./data/etc/nginx/htpasswd:/etc/nginx/htpasswd"
      - "./data/etc/nginx/html:/usr/share/nginx/html"
      - "./data/etc/nginx/conf.d:/etc/nginx/conf.d"
      - "/var/run/docker.sock:/tmp/docker.sock:ro"

  letsencrypt:
    image: jrcs/letsencrypt-nginx-proxy-companion
    environment:
    ### ToDo: Change to your e-mail address
    #      - DEFAULT_EMAIL=admin@demo.io
      - NGINX_PROXY_CONTAINER=nginx-proxy
    volumes_from:
      - nginx-proxy
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./data/etc/certs:/etc/nginx/certs:rw
    restart: always

networks:
  default:
    external:
      name: nginx-proxy
  • Copy the following to /srv/nginx-proxy/data/etc/nginx/conf.d/proxy-settings.conf
proxy_connect_timeout       300;
proxy_send_timeout          300;
proxy_read_timeout          30m;
send_timeout                300;

Note: Add the following line to the file above for large file upload issues: 

client_max_body_size        5000m;

You will need to adjust the size to a value suitable for your environment.

Create docker network

You will need to create an additional docker network for NGINX-Proxy and MediaWiki to talk on:

  • Run docker network create nginx-proxy

MediaWiki

Copy the following to /srv/wiki/docker-compose.yml 

version: '3'
services:
  web:
    image: mediawiki
    build: build/.
    container_name: wiki
    depends_on: 
      - database
    ## parsoid is bundled as part of 1.35+, only uncomment if using an older version
    #  - parsoid
    restart: always
    environment:
      ## TODO: CHANGE VIRTUAL_HOST, LETSENCRYPT_HOST, and LETSENCRYPT_EMAIL TO YOUR OWN
      - VIRTUAL_HOST=wiki.example.com
      - HTTPS_METHOD=nohttp
      - LETSENCRYPT_HOST=wiki.example.com
      - LETSENCRYPT_EMAIL=nobody@example.com
    links:
      - database
    volumes:
      - /srv/wiki/html/images:/var/www/html/images
      ## TODO: remove the # below AFTER you have downloaded the LocalSettings.php file
      #- /srv/wiki/LocalSettings.php:/var/www/html/LocalSettings.php
    networks:
      - default
      - nginx-proxy
  
  database:
    image: mariadb
    container_name: db
    restart: always
    environment:
      MYSQL_DATABASE: mediawiki
      MYSQL_USER: wikiuser
      ## TODO: Change the password below
      MYSQL_PASSWORD: wiki
      ## TODO: Change the password below
      MYSQL_ROOT_PASSWORD: changeme
    volumes:

Mediawiki Docker Image

Here you will find instructions on how to build your own custom MediaWiki docker image.

Dockerfile

There are two ways to create the Dockerfile for MediaWiki.

  • simple uses the MediaWiki image and adds your extension(s) to it.
  • advanced builds the MediaWiki image from scratch and adds your extension(s) to it.

For most users, the simple version of the Dockerfile will suffice.

Extract all extensions to the /srv/wiki/build/extensions directory.

Simple

Copy the following to /srv/wiki/build/Dockerfile

Note: You can change the version of the MediaWiki docker image used by changing the FROM line. 

FROM mediawiki:1.35.3
COPY ./extensions /var/www/html/extensions

Advanced

Note: You can change the version installed by changing:

  • ENV MEDIAWIKI_MAJOR_VERSION 1.36
  • ENV MEDIAWIKI_VERSION 1.36.1
  • ENV MW_VERSION REL1_36

To change to version 1.35 (LTS until 2023) you can substitute 1.35, 1.35.3, and REL1_35 for the values above.

Copy the following to /srv/wiki/build/Dockerfile 

FROM php:7.4-apache

COPY --from=composer /usr/bin/composer /usr/bin/composer

    && git clone --depth 1 https://github.com/dolfinus/AutoSitemap.git

# Copy any other extenions from the ./build/extensions folder
COPY ./extensions $MW_HOME/extensions

CMD ["apache2-foreground"]

Running

First start

  • Update the /srv/wiki/docker-compose.yml file with the hostname (or FQDN for Internet), your email, and database passwords.
  • Run docker-compose up -d to start
  • Login to wiki to complete setup (use http://<hostname/IP> for Intranet or https://<FQDN> for Internet)

Database connection details

  • When prompted for the database enter db://localhost

Note: When prompted have MediaWiki use the same user account (root) for the database that was used for setup. Attempting to use a different user will result in an error and failure. This is due to the MediaWiki setup script attempting to use the database connection string as the hostname for the user (<username>@<connection string>) when granting user access to the database.

LocalSettings File

  • Download when prompted
  • Copy LocalSettings.php to the /srv/wiki directory

Finalize setup

  • Uncomment the #- /srv/wiki/LocalSettings.php:/var/www/html/LocalSettings.php line in the /srv/wiki/docker-compose.yml file
  • chmod 755 the LocalSettings.php file
  • Run docker-compose up -d
  • Wait a minute then navigate to your wiki with https://<hostname/IP> for Intranet or https://<FQDN> for Internet.

Private IPs

Mediawiki will only use the IP presented by the NGINX Proxy server (which will not be the client's real IP). To have Mediawiki trust the X-Forwarded-For (and record them), add the following to the LocalSettings.php file: 

# Use X-ForwardedFor instead for Real IP
$wgUseCdn = true;
$wgCdnServersNoPurge = [];
$wgCdnServersNoPurge[] = "172.18.0.0/24";

Change the 172.18.0.0/24 to the subnet your container is using for talking to the NGINX Proxy.

Reference: https://www.mediawiki.org/wiki/Manual:$wgUsePrivateIPs

Misc

Preventing access

Note: You can also choose an access level at initial installation.

https://www.mediawiki.org/wiki/Manual:Preventing_access#Simple_private_wiki

Upgrading

IMPORTANT: Read https://www.mediawiki.org/wiki/Manual:Upgrading first for information about upgrading.

  1. Update /srv/wiki/build/Dockerfile. Either update version (simple) or make sure Dockerfile has the required dependencies and update version (advanced).
  2. Run docker-compose build

If step 2 is successful:

  1. Run docker-compose up -d
  2. Run docker-compose exec web bash
  3. Run cd maintenance
  4. Run php update.php

File uploads

Allow .pdf files to be uploaded

See https://www.mediawiki.org/wiki/Manual:Configuring_file_uploads#Configuring_file_types

Add this to your LocalSettings.php file: 

$wgFileExtensions = array( 'png', 'gif', 'jpg', 'jpeg', 'doc',
    'xls', 'mpp', 'pdf', 'ppt', 'tiff', 'bmp', 'docx', 'xlsx',
    'pptx', 'ps', 'odt', 'ods', 'odp', 'odg'
);

Increase file upload size

See https://www.mediawiki.org/wiki/Manual:Configuring_file_uploads#Set_maximum_size_for_file_uploads

  • Add this to your LocalSettings.php file to allow uploading of 2G files:
$wgUploadSizeWarning = 2147483647;
$wgMaxUploadSize = 2147483647;
  • Then create /srv/wiki/uploads.ini with the following:
upload_max_filesize = 2048M
post_max_size = 2048M
max_execution_time = 7200
max_file_uploads = 1000
  • Add the following line to the /srv/wiki/docker-compose.yml file under volumes
  - /srv/wiki/uploads.ini:/usr/local/etc/php/conf.d/uploads.ini:ro
