so here’s the story, this is my first time using docker because i was told it is really easy to deploy script, model and many more. Today i try to build my first docker image for my python script using flask. i try to build it and it work on the first couple of iteration and fail like 10 times on the RUN section this is the log

. well of course because of this i search on many places for advice and implement it like dont upgrade pip, use python3, dont use pip to upgrade pip, dont run pip at all, etc i try everything and still fail. also when i delete this line
RUN python -m pip install --upgrade pip
it created another error same like this but for requirements.txt
this is my dockerfile
FROM python:3.9
WORKDIR /flask-finding-driver
COPY finding_driver.py requirements.txt /flask-finding-driver/
RUN python -m pip install --upgrade pip
RUN pip install -r requirements.txt
EXPOSE 5000
ENV FLASK_APP=finding_driver.py
CMD ["flask", "run", "--host=0.0.0.0"]
thank you if youre answering this question really need it fast

This will show if the image has thr wrong architetcure somehow. If it is not amd64, you could try to delete the image and try again running the previous twst commands.

How is it the same error? You have a DNS resolution failure and the original issue was exec format error. Don’t let yourself to be confused by the general title.
