将自定义模块安装到Docker容器中 [英] Installing custom modules into docker container

问题描述

我有几个服务在各自的Docker容器中运行。在我的项目中，我还有一个 lib 文件夹，其中包含一些所有服务都需要的小模块。

I have several services running in their own Docker containers. In my project I also have a lib folder containing some small modules that all the services need.

将这些模块包含在Docker容器中的最佳方法是什么？显然，第三方模块我只使用 RUN pip install -r requirements.txt ，有没有类似的方法可以包含我自己的模块？

What is the best way to include these modules into the Docker containers? Obviously third party modules I just use RUN pip install -r requirements.txt, is there a similar way I can include my own modules?

推荐答案

我最终通过使用将 lib 文件夹安装到容器中来对其进行管理docker-compose ，像这样：

I ended up managing it out by mounting the lib folder into the container using docker-compose, like so:

version: '2'
services:
  frontend_web:
    build: .
    volumes:
      - ../../lib:/app/lib

然后我只需要将/ app / lib添加到容器的 PYTHONPATH 中，就可以从该文件夹导入任何模块。

I then just had to add /app/lib to the container's PYTHONPATH and I could import any module from that folder.
