Issue Description:
Running a Python project using the python-magic library within a Docker container on Windows 10 OS results in the error "Module magic not found."
Proposed Fix:
Initially, changing the dependency from python-magic to python-magic-bin resolved the issue in the local environment. However, when running the project in a Docker container, the same error resurfaced unexpectedly.

Current Challenge: The error "Module magic not found" persists when running the project in a Docker container despite changing the library dependency. Seeking insights or suggestions to overcome this issue. Your thoughts?
After encountering the "Module magic not found" error in the Docker container, I devised a solution by creating separate requirements.txt files for Windows and Linux versions of the project. The Linux version requires python-magic, while the Windows version necessitates python-magic-bin.
Dockerfile With Updated Configuration:
# Dockerfile for API service
FROM python:3.11.0 as base
# Define build arguments
ARG PROJECT=src
ARG TEST=test
# Install dependencies
RUN apt-get update && apt-get install -y \
poppler-utils \
tesseract-ocr \
libgl1-mesa-glx \
libmagic1 \
python3-magic
# Create a non-root user
RUN groupadd --gid 1000 user && adduser --disabled-password --gecos '' --uid 1000 --gid 1000 user
WORKDIR /home/user
USER user
# Development stage setup
FROM base as dev
USER root
COPY --chown=user:user ./requirements-linux.txt ./
RUN pip install --no-cache-dir -r requirements-linux.txt
COPY --chown=user:user ./$PROJECT /home/user/$PROJECT
COPY --chown=user:user ./$TEST /home/user/$TEST
COPY --chown=user:user .env /home/user/.env
USER user
CMD ["python", "-m", "uvicorn", "src.main:app", "--host", "0.0.0.0", "--port", "5000", "--reload", "--env-file", "/home/user/.env"]
# Test stage setup
FROM base as test
COPY --chown=user:user ./requirements-linux.txt ./
RUN pip install --no-cache-dir -r requirements-linux.txt
COPY --chown=user:user ./$PROJECT /home/user/$PROJECT
COPY --chown=user:user ./$TEST /home/user/$TEST
RUN mkdir /home/user/.mypy_cache && chown user:user -R /home/user/.mypy_cache
RUN pip install pytest
CMD ["pytest"]
USER user
# Set the default target stage to 'dev'
FROM dev
By segregating the requirements between Windows and Linux versions and updating the Dockerfile correspondingly, the project now runs smoothly without the "Module magic not found" error in the Docker container.
