Everytime I try setting trusted domains variables before booting, and rebuild my container, there is only localhost being set in config.php. Is there a way I can have the file automatically set on a freshly built container?

The environment variable NEXTCLOUD_TRUSTED_DOMAINS does get loaded onto the server, but the Nextcloud install is not using it.

Honestly, I would even be happy with NEXTCLOUD_TRUSTED_DOMAINS=* at this point to trust all domains.
