That's quite strange.

But you shouldn't need to copy a /start.sh file. If you need startup functionality you should use /app/prestart.sh: https://github.com/tiangolo/uwsgi-nginx-flask-docker#custom-appprestartsh

Unless you are doing custom modifications to the image for your specific purposes.

I make sense, that's my fault.
