Cant get acces to puncover webserver running in Docker container

[ArkadiuszGrzelka]

Hello

I have quite intresting problem.
To development, I'm using docker image, all works fine except puncover.
I Added puncover to docker image by:

RUN pip install puncover
EXPOSE 5000

run docker with port mirroring:
-p 5001:5000/tcp

And after run puncover,
west build -t puncover -d "${PROJECT_BUILD_DIR}"

I got:

* Serving Flask app 'puncover.puncover' (lazy loading)
* Environment: production
WARNING: This is a development server. Do not use it in a production deployment.
Use a production WSGI server instead.
* Debug mode: off
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

Everything seems fine, but I can't get access to puncover output:

Do you have any ideas what is wrong?
My operating system is Ubuntu 22.04

I think the server would need to listen on 0.0.0.0 to be visible outside of the container. See --host 0.0.0.0 CLI option.
Hope this helps :)
