Docker MediaWiki Server

Notes and configuration files for setting up MediaWiki with nginx-proxy for Let's Encrypt SSL certs.

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.

Intranet - no proxy

Use this if on an Intranet with no Internet access. NGINX-Proxy is using Let's Encrypt and will fail without Internet access. If this becomes a heavily used site then consider putting this behind a proxy.

Create /srv/nginx-proxy
Add this file

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:
        - 8080:80
      links:

      volumes:

        ## TODO: remove the # below AFTER you have downloaded the LocalSettings.php file
        #- /srv/wiki/LocalSettings.php:/var/www/html/LocalSettings.php
    database:

      volumes:
        - /srv/wiki/db:/var/lib/mysql
     
     ## parsoid is bundled as part of 1.35+, only uncomment if using an older version
     #parsoid:

     #  container_name: parsoid

     #    - PARSOID_DOMAIN_wiki=http://web/api.php
     #  networks: 
     #    - default

nginx-proxy

Use this if your site is on the Internet

Create /srv/nginx-proxy
Add this file

docker-compose.yml

   version: '2'
   services:
     nginx-proxy:
       image: jwilder/nginx-proxy

       ports:

MediaWiki

Create /srv/wiki, /srv/wiki/build, /srv/wiki/build/extensions
Add the following files

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_35

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

When prompted for the database enter db://localhost

LocalSettings File

Download when prompted
Stop the wiki with docker-compose down
Copy LocalSettings.php to the /srv/wiki directory
Uncomment the #- /srv/wiki/LocalSettings.php:/var/www/html/LocalSettings.php line in the /srv/wiki/docker-compose.yml file

Preventing access

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

Upgrading

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

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

If step 2 is successful:

Run docker-compose up -d
Run docker-compose exec web bash
Run cd maintenance
Run php update.php
