Answer 1

After running the build with pip in verbose mode ( pip install -v ibm-db ), you can see the following error:

No Gcc installation detected.
Please install gcc and continue with the installation of the ibm_db.

ibm-db requires you to have gcc available when installing it, so that you can build it's C modules.

Installing gcc and libc-dev before ibm-db solves the issue:

FROM python:3.9.13-alpine3.16

WORKDIR /app

RUN apk add gcc libc-dev

RUN pip install --upgrade setuptools
RUN pip install --upgrade pip
RUN pip install ibm-db
RUN pip install flask

COPY . .

EXPOSE 8080

CMD ["python", "output.py"]
