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.

nginx-proxy

  • Create /srv/nginx-proxy
  • Add this file

docker-compose.yml

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"
         - "/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

MediaWiki

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

docker-compose.yml

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

   version: '3'
   services:
     web:
       image: mediawiki
       build: build/.
       container_name: wiki
       depends_on: 
         - database
         - parsoid
       restart: always
       #ports:
       #  - 80:80
       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
         #- /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:
         - /srv/wiki/db:/var/lib/mysql
       networks:
         - default
   
     parsoid:
   #    image: pastakhov/parsoid:0.7.1
       image: thenets/parsoid:0.10
       container_name: parsoid
       restart: always
       environment:
   #      - PARSOID_NUM_WORKERS=0
         - PARSOID_DOMAIN_wiki=http://web/api.php
       networks: 
         - default
   
   networks:
     nginx-proxy:
       external:
         name: nginx-proxy

Dockerfile

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

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

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

   FROM php:7.4-apache

Database connection details

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
