Question

我有一个docker-compose文件，直到今天工作正常，当我尝试使用gunicorn启动Web服务器时，它刚刚开始引发错误。日志如下所示：

In file included from /usr/local/include/pybind11/pytypes.h:12:0,
                 from /usr/local/include/pybind11/cast.h:13,
                 from /usr/local/include/pybind11/attr.h:13,
                 from /usr/local/include/pybind11/pybind11.h:44,
                 from /usr/local/include/pybind11/embed.h:12,

 #include <Python.h>
          ^~~~~~~~~~
compilation terminated.

我的dockerfile看起来像

还有该服务器的docker-compose文件：

FROM python:3.7-slim

WORKDIR /app

RUN pip install --upgrade pip

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

COPY . .

有趣的是，我可以在docker映像中打开sh：

services:

  api:
    build: 
      context: .
      dockerfile: ./Dockerfile
    image: flask-pywren
    container_name: flask_apis
    command: /usr/local/bin/gunicorn -w 2 -b :8000 fintech.flask_entrypoint:app
    env_file:
     - ./docker.env
    expose:
      - "8000"
    volumes:
      - .:/app/

并运行

docker run -it flask-pywren sh

和Gunicorn开始正常。我唯一想到的是/usr/local/bin/gunicorn -w 2 -b :8000 fintech.flask_entrypoint:app不是从docker-compose开始的吗？我也将WORKDIR添加到了docker-compose文件中，但这也不起作用。我真的不知道为什么这突然无法按预期工作。

如果您在日志中看到ModuleNotFoundError: No module named 'fintech'，则非常清楚。

您需要安装fintech。

FROM python:3.7-slim

WORKDIR /app

RUN pip install --upgrade pip
RUN pip install fintech

到目前为止docker-compose可以改变docker的行为

    volumes:
      - .:/app/

它将覆盖/app下在构建期间COPY . .复制的所有内容

gunicorn ModuleNotFound错误，以前可以正常工作
