我刚开始使用docker compose，并一直在使用这个简单的demo flask应用程序。问题是，我在一个组织内部运行这个应用程序，它拦截所有的通信，以这样一种方式抛出SSL错误。它们为我们提供了三个需要安装的根证书，我通常在自己的机器上使用这些证书。但是当涉及到如何让这些在停靠组合部署中工作时，我就不明白了。
当我运行docker-compose时，我得到以下结果：

$ sudo docker-compose up

Pip安装任何东西都失败。
docker-compose.yml文件如下所示：

version: '3'
services:
  web:
    build: .
    ports:
     - "5000:5000"
  redis:
    image: "redis:alpine"

主Dockerfile如下所示：

FROM python:3.4-alpine
ADD . /code
WORKDIR /code
RUN pip install -r requirements.txt
CMD ["python", "app.py"]

在这种情况下，是否有任何方法可以使其工作？是否有一个通用的解决方案可以解决这类问题，允许我将SSL证书传递到任何部署的容器，并使用它们？
