我将app.py设置为调试模式：

from flask import Flask, render_template

app = Flask(__name__)

@app.route('/')
def home():
    return render_template('home.html', title='Title Here')

# ...
# more routes here
# ...

if __name__ == '__main__':
    app.run(debug=True)

Python库geopandas把我的本地机器弄得一团糟，这就是为什么我决定把我的应用程序停靠起来，它工作得很好！（除了 flask 调试模式）
我的Dockerfile看起来像这样。我尝试了debugpy库，但没有成功：

FROM python:3.9-slim as base

# Setup env
ENV LANG C.UTF-8
ENV LC_ALL C.UTF-8
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONFAULTHANDLER 1

FROM base AS python-deps

# Install pipenv and compilation dependencies
RUN pip install pipenv
RUN apt-get update && apt-get install -y --no-install-recommends gcc

# Install python dependencies in /.venv
COPY Pipfile .
COPY Pipfile.lock .
RUN PIPENV_VENV_IN_PROJECT=1 pipenv install geopandas
RUN PIPENV_VENV_IN_PROJECT=1 pipenv install debugpy
RUN PIPENV_VENV_IN_PROJECT=1 pipenv install --deploy
CMD pipenv debugpy

FROM base AS runtime

# Copy virtual env from python-deps stage
COPY --from=python-deps /.venv /.venv
ENV PATH="/.venv/bin:$PATH"

WORKDIR /home

# Install application into container
COPY . .

然后我用这个来构建图像：
docker build -t <IMAGE-NAME:HERE> .
然后我用这个脚本初始化docker容器：
docker run --rm -ti --mount type=bind,source=/"$(pwd)",target=/home -p 5000:5000 <IMAGE-NAME:HERE> flask run --port 5000 --host 0.0.0.0 --debugger
除调试模式外，其他一切都正常：

* Debug mode: off
WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead.
 * Running on all addresses (0.0.0.0)
 * Running on http://127.0.0.1:5000

有什么想法吗？
