What is ddev-drushonhost?

In DDEV v1.22.4+, the former facility to use the Drupal drush command on the host was removed. That usage was always fragile, but some people liked and used it. This add-in also permits running PHPUnit/DTT (Drupal Test Traits) tests on the host instead of running them in the containers. See this article for more on running DTT on the host

This add-on adds that facility again.

One-time in project:

ddev get rfay/ddev-drushonhost

When using drush on the host you need:

export IS_DDEV_PROJECT=true

OR

In your project settings.php make sure the end of the file looks like this:

if (file_exists($app_root . '/' . $site_path . '/settings.local.php')) {
  include $app_root . '/' . $site_path . '/settings.local.php';
}

// Automatically generated include for settings managed by ddev.
$ddev_settings = dirname(__FILE__) . '/settings.ddev.php';
if (getenv('IS_DDEV_PROJECT') == 'true' && is_readable($ddev_settings)) {
  require $ddev_settings;
}

and then add this to your settings.local.php:

putenv("IS_DDEV_PROJECT=true");

Running drush commands in the containers is faster, however, dependingon your use, you may find it more convenient to run them on the host. Read more about installing Global Drush and using this add-in. Note. The host drush version doesn't matter much since it is only used to find the proper drush (most likely within /vendor/bin) and call it. This means you always run the version of drush that you installed in your project using composer.

From the former documentation:

Warning: We don’t recommend using drush on your host machine. It’s also mostly irrelevant for Drupal 9+, as you should be using Composer-installed, project-level drush.

If you have PHP and Drush installed on your host system and the environment variable IS_DDEV_PROJECT=true, you can use Drush to interact with a DDEV project. On the host machine, extra host-side configuration for the database and port in settings.ddev.php allow Drush to access the database server. This may not work for all Drush commands because the actual web server environment is not available.

On Drupal 8+, if you want to use drush uli on the host (or other Drush commands that require a default URI), you’ll need to set DRUSH_OPTIONS_URI on the host. For example, export DRUSH_OPTIONS_URI=https://mysite.ddev.site.
