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

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.

version: '2'

services:
  web:
    image: hacklab/wordpress
    environment:
      - WORDPRESS_DEBUG=true
      - WORDPRESS_DB_USER=the_db_user
      - WORDPRESS_DB_PASSWORD=the_db_pass
      - WORDPRESS_DB_NAME=the_db_name
    ports:
      - "80:80"

  mysql:
    image: mariadb
    environment:
      - MYSQL_USER=the_db_user
      - MYSQL_PASSWORD=the_db_pass
      - MYSQL_DATABASE=the_db_name
      - MYSQL_ROOT_PASSWORD=the_root_pass
      - TERM=xterm

X-Debug

When you set WORDPRESS_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.

Atom users

Tell your Atom about folder mapping by editing config.cson. You have to configure the section called "php-debug". It should look like this:

  "php-debug":
    PathMaps: [
      "remotepath;localpath"
      "/var/www/html/;/local/path/to/wordpress/"
    ]
    PhpException:
      CatchableFatalError: false
      Deprecated: false
      FatalError: false
      Notice: false
      ParseError: false
      StrictStandards: false
      UnknownError: false
      Warning: false
      Xdebug: false
