It would be great if the Drupal-PHP image allows to pass the same build arguments as the base PHP image: https://github.com/wodby/php#build-arguments
We had several write issues with running composer inside the Drupal-PHP container which had to be solved by passing the UID and GID as build arguments. We had to combine the Dockerfiles from both wodby/php and wodby/drupal-php to get this working.
