python - Flask Docker应用程序不提供API并且在Docker镜像内未找到文件

Question

我有一个flask应用程序，想通过Docker对其进行容器化。通常，我使用flask run运行该应用程序，并且该应用程序在端口8888上提供API。但是，当我尝试使用docker运行该应用程序时，该API无法启动。我使用docker-compose build --no-cache构建图像，并开始使用docker-compose -f docker-compose.yml up，容器启动。我使用docker exec -it covid-api /bin/bash，我到达root@d0659f0c1627:/app#，而ls不返回任何内容。它是空的。

这是我的文件夹结构:



以下是我的docker配置:

FROM python:3.7-stretch
WORKDIR /app

COPY ./badproxy /etc/apt/apt.conf.d/99fixbadproxy

RUN apt-get update \
 && apt-get install -y curl apt-utils gcc build-essential apt-transport-https ca-certificates \
 && curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add - \
 && curl https://packages.microsoft.com/config/debian/9/prod.list > /etc/apt/sources.list.d/mssql-release.list \
 && apt-get update \
 && ACCEPT_EULA=Y apt-get install -y msodbcsql17 unixodbc-dev mssql-tools locales \
 && echo "en_US.UTF-8 UTF-8" > /etc/locale.gen \
 && locale-gen

COPY .flaskenv ./
COPY requirements.txt ./
RUN pip install -r requirements.txt

ENV FLASK_ENV=development
ENV PATH="/opt/mssql-tools/bin:${PATH}"

COPY . ./

CMD python setup.py develop

CMD ["flask", "run", "-h", "0.0.0.0", "-p", "8888"]

请指教。非常感谢您的帮助。

可能的问题是您的项目没有MANIFEST.in文件。当setup.py执行时，它会寻找其他文件以包含到您的项目中。完整的说明可以在here中找到。

对于您的项目文件夹，它可能看起来像这样。

recursive-include src/*
recursive-include src/api *
recursive-include src/api/controllers *
recursive-include src/api/controllers/endpoints *
