How to setup MediaWiki as a docker container

Question

I cannot seem to understand how to setup MediaWiki in a docker container.

1. Based on the MediaWiki documentation, I have prepared a yaml file as follows:

version: '3'
services:
  mediawiki:
    image: mediawiki
    restart: always
    ports:
      - 8080:80
    links:
      - database
    volumes:
      - images:/var/www/html/images
      # After initial setup, download LocalSettings.php to the same directory as
      # this yaml and uncomment the following line and use compose to restart
      # the mediawiki service
      # - ./LocalSettings.php:/var/www/html/LocalSettings.php
  # This key also defines the name of the database host used during setup instead of the default "localhost"
  database:
    #image: mariadb
    image: mysql
    restart: always
    environment:
      # @see https://phabricator.wikimedia.org/source/mediawiki/browse/master/includes/DefaultSettings.php
      MYSQL_DATABASE: my_wiki
      MYSQL_USER: wikiuser
      MYSQL_PASSWORD: example
      MYSQL_RANDOM_ROOT_PASSWORD: 'yes'
    volumes:
      - db:/var/lib/mysql

volumes:
  images:
  db:

2. I then start the containers using docker-compose -f mediawiki.yml up and the mediawiki and database container are up

3. When accessing the url localhost:8080 , I see

MediaWiki 1.38.2
LocalSettings.php not found.
Please complete the installation and download LocalSettings.php.

I now perform the configuration with the following database parameter:

Database type: MariaDB, MySQL, or compatible
Database host: database
Database name (no hyphens): my_wiki
Database table prefix (no hyphens):
Database username: wikiuser
Database password: example

4. After the configuration is complete I see the following error message and am stuck:

Setting up database...
[64989d89dafa96653c6354f1] /mw-config/index.php?page=Install Wikimedia\Rdbms\DBQueryError: A database query error has occurred. Did you forget to run your application's database schema updater after upgrading or after adding a new extension?

What am I missing here?

Not a docker expert but have you done the setup shown the middle of your Yamal file under images?
