docker-compose - CommandError: /code/manage.py 已经存在，将项目或应用程序覆盖到现有目录中不会替换冲突文件

问题描述

我正在尝试在 Windows 上运行 linux docker 并收到此错误。

构建很好。

'''

但是当我运行撰写时..我看到以下错误。

'''
$ docker-compose up

如果我试试这个

'''
docker-compose run web django-admin startproject composeexample .
'''

它说

'''
CommandError: /code/manage.py already exists, overlaying a project or app into an existing directory won't replace conflicting files
'''

我的 Dockerfile 是

'''
FROM python:3
ENV PYTHONUNBUFFERED 1
RUN apt-get update -y
RUN apt-get install -y unixodbc unixodbc-dev
RUN easy_install pip
RUN mkdir /code
WORKDIR /code
RUN pip uninstall django
COPY requirements.txt /code/
RUN pip install -r requirements.txt 
COPY . /code/
'''

我的 docker-compose.yml 是 ''' 版本：'3'

services:
  web:
    build: .
    command: python manage.py runserver case.xxxxxx.com:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"

''' 如何解决 composeexample 的问题？它甚至没有被创建（因为我在文件夹中看不到它）.. 请您提出建议。
