I have a Drupal 8 website on Docker containers. Drupal sites folders contains, besides the default folder, two folders, the settings.php file, and configuration.
The goal is to have different configuration inside each folder (inside each settings.php) and connected to same or different database.
Because client wants only one instance of Drupal (a single set of containers), how can I manage the website to change symlink from the default folder to each folders with different configurations?
