How to specify path to drush so ddev can find it?

[kenorb]

My composer.json is in drupal/.
In .ddev/config.yaml I've the following values:

docroot: drupal/web
composer_root: drupal

Drush works when I execute by:

% ddev composer exec drush version
Using '/var/www/html/drupal' as Composer root directory
Drush version : 12.5.2.0

However it doesn't work when executed by:

% ddev drush
drush is not available. You may need to 'ddev composer require drush/drush'

How I can specify path to drush, so ddev can find it?

Hi @kenorb - It seems like you haven't installed drush (per the message), or your composer_root isn't set? Where is your vendor directory, and does it contain vendor/bin/drush?

Sorry, you seem to have told me that. Just reading messages when I got back. It looks to me like your composer_root is correct. Does drupal/vendor/bin/drush exist? ddev exec ls -l /var/www/html/drupal/vendor/bin/drush ?

DDEV tries to add to the PATH what you need. But I assume ddev exec drush doesn't work because the PATH isn't right?

I think working_dir for web will help:

ddev config --web-working-dir=/var/www/html/drupal

working_dir:
    web: /var/www/html/drupal

I had no trouble with this arrangement:

ddev config --project-type=drupal --docroot=drupal/web --composer-root=drupal
ddev start
ddev composer create drupal/recommended-project
ddev composer require drush/drush
ddev drush --version

My resultant directory tree looked like this. Is this the same as yours?

If you can't figure it out quickly, try adding a post-start exec hook that does a sudo ln -sf /var/www/html/drupal/vendor/bin/drush /usr/local/bin/drush. That could probably also go in a .ddev/web-build/Dockerfile.drush
