Try It Out

To take the Minimus WordPress image for a test run, we will use Docker Compose to create a simple self-hosted web-page with MySQL and NGINX as our proxy server.

Next, save the sample nginx.conf file to your project directory. Link to file

Save the following code to a new file compose.yaml in your project directory:

services:
  wordpress:
    image: reg.mini.dev/wordpress
    container_name: wordpress
    ports:
      - "8080:80"  # Expose WordPress on port 8080 of the host
    environment:
      - WORDPRESS_DB_HOST=mysql:3306
      - WORDPRESS_DB_NAME=wordpress
      - WORDPRESS_DB_USER=wordpressuser
      - WORDPRESS_DB_PASSWORD=wordpresspassword
    volumes:
      - wordpress_data:/var/www/html  # Persist data for WordPress
    depends_on:
      - mysql  # Wait for the MySQL container to be ready

  nginx:
    image: reg.mini.dev/nginx
    container_name: nginx
    ports:
      - "80:80"  # Expose nginx on port 80 of the host
    volumes:
      # Mount your custom nginx configuration
      - ./nginx.conf:/etc/nginx/nginx.conf
      # Link to WordPress volume to serve content
      - wordpress_data:/var/www/html  
    depends_on:
      - wordpress # Wait for the WordPress container to be ready

  mysql:
    image: reg.mini.dev/mysql
    container_name: mysql
    environment:
      MYSQL_ROOT_PASSWORD: rootpassword
      MYSQL_DATABASE: wordpress
      MYSQL_USER: wordpressuser
      MYSQL_PASSWORD: wordpresspassword
    volumes:
      - mysql_data:/var/lib/mysql  # Persist data for MySQL
    ports:
      - "3306:3306"  # Expose MySQL on port 3306 of the host

volumes:
  mysql_data:         # Named volume to persist MySQL data
  wordpress_data: # Named volume to persist WordPress data

As an extra precaution, you can add the WORDPRESS_CONFIG_EXTRA environment variable to block automatic updates and disable the option to install new themes and plugins.

WORDPRESS_CONFIG_EXTRA: |  
  define( 'DISALLOW_FILE_MODS', true ); # Disables plugin and theme installations and updates
  define( 'AUTOMATIC_UPDATER_DISABLED', true );   # Disables automatic background updates

Run the app:

docker compose up

Visit the WordPress default welcome page at http://localhost. (Since NGINX is exposed on port 80, there's no need to specify the port.)

If you're working in a VM, run curl ifconfig.me to look up your external IP and substitute it like this: http://{IP}. You will be automatically redirected to http://{IP}/wp-admin/install.php.

Once ready to clean up, run the following command to remove the containers and their associated volumes:

docker compose down -v

Technical Considerations

The WordPress image provided by Minimus is a slim, security-hardened alternative to the public image from Docker Hub. The images are largely interchangeable, with a few differences as noted below.
