What is the purpose of the Docker Compose file in this setup?

The Docker Compose file is used to define and run multi-container Docker applications, specifying the services, networks, and volumes needed for the WordPress development environment.

Which web server is used in the video for the local WordPress development?

The web server used in the video is Nginx, specifically the Nginx 1.15.2 Alpine version.

How does the presenter ensure the Nginx configuration is updated for local development?

The presenter maps a local 'enginex' folder to the Nginx configuration directory within the Docker container to overwrite the default configuration with a custom one.

What is the significance of the 'fpm' in the WordPress Docker image?

The 'fpm' stands for FastCGI Process Manager, which is used to handle PHP processing for WordPress, allowing Nginx to serve PHP files properly.

How is the MySQL database service configured in the Docker Compose file?
