How: Using app nextcloud-theming-domain to logos

So, you are using multiple domains (two in my case) for your Docker Nextcloud, thats what the TRUSTED_DOMAINS is for in your config.php, but what if you want logos for each, well thanks to mediabox-cl & mepsteinj we have nextcloud-theming-domain

Installed it, navigated to the config folder on the web root of the nextcloud volume and edit the theming file.

nano /mnt/shared/nextcloud/web/config/theming.domain.config.php

<?php
# Domain Theming APP Config file (theming.domain.config.php).
$CONFIG = array(
    'theming_domain' => array(
        'nextcloud.example1.com' => array(
        'variables' => array(
        '--image-logo' => "url('/domains/example1/example1_logo.png')",
        '--image-logoheader' => "url('/domains/example1/example1_small_logo.png')"
                            )
                                       ),
        'nextcloud.example2.com' => array(
        'variables' => array(
        '--image-logo' => "url('/domains/example2/example2_logo.png')",
        '--image-logoheader' => "url('/domains/example2/example2_small_logo.png')"
		                                 )
                             )
);

Happy days, each domain has its own logo.
Just wanted to make someones life a little bit easier.
