PermissionError:[Errno 13] 权限被拒绝:'/manage.py'

问题描述

我正在尝试在 docker-composer 中运行以下命令，以使用 django-admin 启动项目:

I am trying to run the following command in docker-composer, to start project with django-admin:

docker-compose run app sh -c "django-admin startproject app ."

这会产生错误:

    Traceback (most recent call last):
  File "/usr/local/bin/django-admin", line 10, in <module>
    sys.exit(execute_from_command_line())
  File "/usr/local/lib/python3.7/site-packages/django/core/management/__init__.py", line 381, in execute_from_command_line
    utility.execute()

    with open(new_path, 'w', encoding='utf-8') as new_file:
PermissionError: [Errno 13] Permission denied: '/manage.py'

Dockerfile如下:

The Dockerfile is as follows:

FROM python:3.7-alpine
MAINTAINER anubrij chandra

ENV PYTHONUNBUFFERED 1

COPY ./requirements.txt /requirements.txt

RUN pip install -r /requirements.txt

RUN mkdir /app
COPY ./app /app



RUN adduser -D dockuser
USER dockuser

我的docker-compose.yml:

version: "3"

services:
  app:
    build:
      context: .
    ports:
      - "8000:8000"
    volumes:
      - ./app:/app
    command: >
      sh -c "python manage.py runserver 0.0.0.0:8000"

我应用了 这个 Stack Overflow 线程，但它没有工作.

推荐答案

在你的 dockerfile 中，你指向一个新用户 dockuser.

In your dockerfile, you are pointing to a new user dockuser.

RUN adduser -D dockuser
USER dockuser

因此，您的容器将以用户 dockuser 开始，该用户似乎没有适当的权限来运行 /manage.py.

Hence your container will start with user dockuser which don't seems to have proper permissions to run /manage.py.

你可以

• 删除上面提到的您创建并指向的行dockuser.

或

• 在/manage.py 文件的 dockerfile 中使用 chown 和 chmod 命令为用户 dockuser 提供适当的权限.

• provide appropriate permission to user dockuser using chown and chmod commands in your dockerfile for /manage.py file.
