A basic Docker Compose file to launch a container for WordPress and a second for MySQL.

• Launch this with 'docker-compose up'
• Then connect to http://localhost:8080/ to go through the WordPress installation process.

NOTES:

• YOU SHOULD CHANGE THE PASSWORDS in the file (but make sure WORDPRESS_DB_PASSWORD and MYSQL_PASSWORD are the same).
• You may need to change the port number 8080 if you have some other service running on that port.
• A "wp-content" directory will be created in your current directory which will hold themes, plugins and other content you add to your WordPress installation.

I originally posted a request for a step-by-step tutorial about how to use the 'wordpress' Docker image. wglambert was kind enough to come back with a simple and easy-to-use Docker Compose YAML file.
