[Podman] Podman pulls image every time --build is passed to compose on Mac

I was expecting Podman to avoid pulling images again every time I run "docker-compose up --build" on Mac (Apple Silicon). I only want the new Python dependencies (in requirements.txt) to be added to the container image, but don't see the necessity of pulling the 200MB image once again each time. Is this expected behavior?  Here's my Containerfile: FROM docker.io/library/python:3.12 COPY . /app WORKDIR /app RUN pip install -r requirements.txt CMD ["python", "app.py"]
