Question

我是Docker的新手。我正在尝试将我在ubuntu的anaconda3中创建的简单django应用程序进行docker化。

我的dockerfile看起来像这样：

# Pull base image
FROM continuumio/anaconda3

# Set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

# Set work directory
WORKDIR /code

COPY requirement.txt /code/
RUN conda install --file requirement.txt

# Copy project
COPY . /code/

requirement.txt是我的conda虚拟环境中的依赖项软件包的列表。我通过在conda激活的环境中运行以下代码来获得该信息：

conda list -e > requirement.txt 而软件包django=3.0.3=py_0在此requirement.txt

中

此外，这时，我已经正确安装了docker并提取了基础映像continuumio/anaconda3。

这是我的docker-compose.yml文件：

version: '3.8'

services:
  web:
    build: .
    command: python /code/manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - 8000:8000

现在，当我运行docker-compose up时，我收到了以下错误消息链（到此为止，requirement.txt中的所有依赖包都已安装）：

web_1  | Traceback (most recent call last):
web_1  |   File "/code/manage.py", line 10, in main
web_1  |     from django.core.management import execute_from_command_line
web_1  | ModuleNotFoundError: No module named 'django'
web_1  | 
web_1  | The above exception was the direct cause of the following exception:
web_1  | 
web_1  | Traceback (most recent call last):
web_1  |   File "/code/manage.py", line 21, in <module>
web_1  |     main()
web_1  |   File "/code/manage.py", line 16, in main
web_1  |     ) from exc
web_1  | ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?
hello_project_web_1 exited with code 1

我的问题：我做错了什么？码头工人为何要求激活虚拟环境？容器本身现在不是“虚拟环境”吗？

我看到了一个使用“ pip” here的有效示例。但是我习惯了conda，很想弄清楚这一点。

谢谢
