Full Description

WordPress development on Docker [DEPRECATED]

NOTE: This image is no longer updated. Unless you need Xdebug, I recommend
that you work instead from the official WordPress images, as shown in my
Docker Compose WordPress development repo.


Environment variables

  • WORDPRESS_ACTIVATE_PLUGINS: A space-separated list of plugin paths relative
    to /var/www/html/wp-content/plugins/ that should be activated when the
    container starts. If a plugin cannot be found, an install will be attempted
    via wp plugin install.

  • WORDPRESS_ACTIVATE_THEME A theme path relative to /var/www/html/wp-content/themes/
    that should be activated when the container starts. If the theme cannot be
    found, an install will be attempted via wp theme install.

  • WORDPRESS_CONFIG_EXTRA: Additional PHP to append to wp-config.php.

  • WORDPRESS_DB_HOST: Default "mysql".

  • WORDPRESS_DB_NAME: Default "wordpress".

  • WORDPRESS_DB_USER: Default "root".

  • WORDPRESS_DB_PASSWORD: Default "".

  • WORDPRESS_INSTALL_TYPE: Default "single" (use "multisite" for Multisite install).

  • WORDPRESS_PERMALINK_STRUCTURE: Default "/%year%/%monthnum%/%postname%/"

  • WORDPRESS_SITE_USER: Default "wordpress"

  • WORDPRESS_SITE_PASSWORD: Default "wordpress"

  • WORDPRESS_SITE_EMAIL: Default "admin@example.com"

  • WORDPRESS_SITE_TITLE: Default "Project".

  • WORDPRESS_SITE_URL: Default "http://project.dev".

WP-CLI

Assuming you are running in the context of Docker Compose:

docker-compose exec --user www-data wordpress wp [command]

Running tests (PHPUnit)

Previous versions of this image provided PHPUnit inside the container. However,
bundling a single version of PHPUnit was not very flexible. Additionally, users
did not have the opportunity to install their own test dependencies. I now
provide a(n optional) separate PHPUnit WordPress container that provides much
greater flexibility and isolation. Please see the README of my
Docker Compose WordPress development repo for instructions on how
to set this up.

Xdebug

Xdebug is installed but needs the IP of your local machine to connect to your
local debugging client. Edit .env and populate the DOCKER_LOCAL_IP
environment variable with your machine's (local network) IP address. The default
idekey is xdebug.

XDEBUG_CONFIG: "remote_host=x.x.x.x idekey=xdebug"

You can enable profiling by appending additional instructions, e.g.:

XDEBUG_CONFIG: "remote_host=x.x.x.x idekey=xdebug profiler_enable=1 profiler_output_name=%R.%t.out"

This will output cachegrind files (named after the request URI and timestamp) to
/tmp inside the WordPress container.

Seed wp-content

You can seed wp-content with files (e.g., an uploads folder) by mounting a
volume at /tmp/wordpress/init-wp-content. Everything in that folder will be
copied to your installation's wp-content folder.

Provide trusted root certificates

Mount a folder of trusted root certificates to /tmp/certs. Any files in that
folder with a .crt extension will be added to the trusted certificate store.
