SamRueby awesome, I tried multiple times to use the startup command to manipulate the container and it never worked like on the Azure Container Instances - thanks for the info
I am still running into a font loading issue as soon as I install the BuddyBoss theme (which is working on all systems I used before without any issue), so I expect an issue in the underlying default configuration of either nginx or php-fpm. Tried to debug, spot and fix it with MIME types, extensions and NGINX content security policy via SSH - but was unable to get it working so far. There's a lot of javascript used in that theme, but the CSS files and the fonts itself are hosted locally - so it is no CORS issue. I already opened a ticket with their support, and they were suspecting a CSS issue, but the CSS files itself are loading according to browser developer tools. As I am on a Visual Studio subscription here right now, I cannot open a ticket to Microsoft directly. In case someone who is more skilled would like to take a look at it with dev tools in the browser: https://blackrhinoteam.azurewebsites.net/wp-login.php should show icons based out of fonts from a CSS on the left inside the Email Address and the Password field. Any pointers to what could be the issue are welcome.
