Can't launch the app via docker-compose or direct gunicorn command

[northwestwitch]

Hi @Vince-janv and @ramprasadn. I'd like to revive this project and I'm trying to launch the application.

Using docker-compose (docker-compose up) doesn't work. I get the following error:

(chanjo2) chiararasi@ChiaraRMBP:~/Documents/work/GITs/chanjo2$ docker-compose up

Same when I invoke the gunicorn command: gunicorn --config gunicorn.conf.py src.chanjo2.main:app (I guess?):

I see where the error is in both cases. If you don't mind I'd like to write a basic fix and some instructions to run the app in README?

The Docker image is huge at the moment:

Would also be nice to minify it

Thanks for fixing the issue, Chiara! Good point about the size of the image. Would be nice to keep it lean 😄
