WordPress Docker Image

This is an image to help on plugins and themes development, but it can be used to host a WordPress site as well. There are some tools and nice librarys included, like OPCache, X-Debug and WP-Cli.

Development environment (WP_DEBUG=true)

There are a WordPress installed at /var/www/html. So if you want to develop a plugin, you can mount your content mapping your plugin folder in /var/www/html/wp-content/plugins.

Let's suppose you want to test your plugin called Awesome, your docker-compose.yml should be like this below.

web:
  image: montefuscolo/wordpress
  volumes:
   - ./Awesome:/var/www/html/wp-content/plugins/Awesome
  environment:
   - WP_DEBUG=true
  links:
   - db:mysql
  ports:
   - "80:80"

db:
  image: mariadb
  environment:
   - MYSQL_USER=thewpuser
   - MYSQL_PASSWORD=thewppass
   - MYSQL_DATABASE=wordpress
   - MYSQL_ROOT_PASSWORD=thesuperpass
   - TERM=xterm

X-Debug

When you set WP_DEBUG=true in container environment, the X-Debug configuration will be created automatically, and the container will receive connections from any host. If you want suppress X-Debug, set an enviroment variable with false value, like XDEBUG=false.

Production Environment

Without WP_DEBUG, the container will create automatically the configuration file to OPCache. You can suppress this behavior by setting in environment OPCACHE=false.
