Docker file:

FROM python
COPY . /app
WORKDIR /app
RUN pip install -r python_modules.txt
ENTRYPOINT ["python"]
CMD ["app.py"]

Answer 1

Without seeing the docker file this looks as though the port is not open.

• you need to explicitly expose the port via the dockerfile
• you can change the entrypoint aswell.
• you need to have the following in the dockerfile

ENTRYPOINT python app.py
EXPOSE 5000
