使用来自另一个 docker 容器的 python 包

Question

How can I use python packages from another container?

ydk-py is set up with everything that I need, including all python packages and their dependencies. I want to use those python packages in my django application. However python imports packages installed in my main container, web , and not ydk-py .

docker-compose:

version: '3.7'

services:
  web:
    container_name: webserver
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code/
    ports:
      - 8000:8000
    env_file:
      - .env.dev
    depends_on:
      - db

  db:
    container_name: database
    image: postgres:13.0-alpine
    volumes:
      - postgres_data:/var/lib/postgresql/data/
    env_file:
      - .env.dev

  ydk-py:
    container_name: ydk-py
    image: ydkdev/ydk-py:latest
    tty: true

volumes:
  postgres_data:

Dockerfile:

FROM python:3.6.12-alpine

you should be able to use ydk-py as your base image to build your application

FROM ydkdev/ydk-py:latest
...
