Multi-Site Setup
Drupal can support multiple sites with a single codebase. This makes it easy to manage updates all at once. Be careful to only push updates that will not break the site.
A single Drupal site uses the web/sites/default directory. Multi-site setups have an additional directory per site.
Sites.php
/web/sites/sites.php
This file tells Drupal how to map domain names to the directory in /web/sites.
Settings.php
The main Drupal configuration file.
Trusted Host Pattern
Prevent your site from being spoofed from another URL.
Settings.local.php
Environment specific config and development options. See example.settings.local.php.
You can put sensitive environment config like the database credentials and hash salt in here and ignore it in git.
Development.services.yml
Located in /web/sites.
Development configuration.
