That seems like a mistake in the design of the compose file mentioned (not using the “{{ domain }}” pattern in the LEMMY_UI_LEMMY_EXTERNAL_HOST environment variable) in the docs and a case of the documentation not being explicit about what needs to be changed (they refer to that variable in the README of the Lemmy UI repo when you read about the config file mentioned in the docs).
Here is the commit github.com/…/b3bd2afd6af18e71048ade7e82b541ff903a…
It creates the docker file and updates the docs to (among other things) point to the he file, the old being raw.githubusercontent.com/…/docker-compose.yml.
I wonder why it does not point to the main repo. The PR does not discuss the it. github.com/LemmyNet/lemmy-docs/pull/315

Yeah, without a doubt, it’s just an oversight.
There’s nothing malicious here.
I should have read the docker compose a bit closer when I was trying to figure it out but There’s only so many hours in the day, and sometimes you rush.
