Your issue
See above. When deploying python application, and running pip install -r requirements.txt, it is saying that requirements.txt is not found, even though it is present in the git repo.

Dockerfile content (if any)

FROM python:3

RUN pip install -r requirements.txt

CMD python -u

you should look at this quick guide about writing dockerfile.
