ng serve (alt): Set allowed hosts via environment variable#19691Conversation
Vite now supports specifying allowed hosts as an `__VITE_ADDITIONAL_SERVER_ALLOWED_HOSTS`. Alternative fix to a1555af: Only overrides allowed hosts in the development environments that need it (i.e. Docker + TLS stack).

Assuming that it's non-breaking for other users, could we specify this on the docker-compose.yml already? Then it would work out of the box for everyone using the default hostnames. If you want to use a different hostname, the override is still possible.
It seems to be fine to have these ports settings as well as __VITE_ADDITIONAL_SERVER_ALLOWED_HOSTS envvar set in docker-compose.yml directly. So, there is less to override to get your docker TLS dev stack working.
