我正在使用docker设置和维护我的Flask应用程序的开发环境。不幸的是，在我使用以下方法启动应用后：
docker run -i -p 8000:8000 vosw2
我无法使用输出指定的Ctrl-C终止应用程序的运行。
$ docker run -i -p 8000:8000 vosw2

关于为什么以及如何解决此问题的任何想法？
我的Dockerfile如下所示：
# Use an official Python runtime as a parent image
FROM python:2.7-slim
# Set the working directory to /EducationWebApp
WORKDIR /EducationWebApp
# Copy the current directory contents into the container at /EducationWebApp
ADD . /EducationWebApp
# Install any needed packages specified in requirements.txt
RUN pip install --trusted-host pypi.python.org -r requirements.txt
# Make port 8000 available to the world outside this container
EXPOSE 8000
# Run app.py when the container launches
CMD ["python", "app.py"]
然后我用docker build -t vosw2 .来制作图片。
