我有一个docker-compose文件，直到今天都工作得很好，但当我尝试用gunicorn启动我的was服务器时，它就开始抛出一个错误。日志如下所示：

    flask_apis  | [2019-09-05 21:20:04 +0000] [1] [INFO] Starting gunicorn 19.9.0

我的dockerfile看起来像这样

FROM python:3.7-slim

WORKDIR /app

RUN pip install --upgrade pip

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

COPY . .

以及用于该服务器的docker合成文件：

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/

有趣的是，我可以在docker图像中打开sh：

docker run -it flask-pywren sh

然后运行

/usr/local/bin/gunicorn -w 2 -b :8000 fintech.flask_entrypoint:app

而gunicorn启动得很好。我唯一能想到的就是docker-compose不是从WORKDIR开始的？我还将working_dir: "/app"添加到docker-compose文件中，但这也不起作用。我真的很困惑，为什么这突然不能像预期的那样工作。

gunicorn

python

docker

docker-compose

如果您在日志中看到了非常清楚的ModuleNotFoundError: No module named 'fintech'。

您需要安装fintech。

FROM python:3.7-slim

WORKDIR /app

RUN pip install --upgrade pip
RUN pip install fintech

就docker-compose而言，可以改变docker的行为是

    volumes:
      - .:/app/

它将覆盖在构建时COPY . .期间复制/app下的所有内容
