I have rails7 app running in container fine. but I cant access it from 'outside' seems like docker/colima is not forwarding port, but other apps (sinatra) on the same settings works fine.
docker run -d -p 5678:5678 rails7_docker:v1
...
EXPOSE 5678
RUN rails s -b 0.0.0.0 -p 5678
docker ps

I have no idea where to look for solution or how to debug, as other projects works fine but this not. It's default rails new project with no modifications. ruby - 3+ rails7, os x, docker + colima, intel mac.
if you need any more details, please ask.
If you use
--network="host", it should work.
