Docker only install instructions run into database connection error trac does not exist #2193
Description
When trying to follow just the docker instructions, we ran into an issue. It seems to be related to some combo of the installation instructions missing some steps that would still be relevant for Docker or some outdated or commented out lines in entrypoint.
Traceback for future reference:
docker compose run --rm web python -m manage test
