权限被拒绝：'/app/manage.py' Docker

Question

我在尝试运行 docker-compose 命令时遇到权限问题

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

错误：

PermissionError: [Errno 13] Permission denied: '/app/manage.py'

我做了一些研究，在这里发现了一个类似的问题：docker-compose , PermissionError: [Errno 13] Permission denied: '/manage.py'

但是，当我尝试更改 Dockerfile 中的权限时，我认为我做错了

Dockerfile：

FROM python:3.8-alpine
MAINTAINER Nick

ENV PYTHONUNBUFFERED 1

COPY ./requirements.txt /requirements.txt
RUN pip install -r /requirements.txt

RUN mkdir /app
WORKDIR /app
COPY ./app /app

RUN adduser -D user
RUN chown user:user -R /app/
RUN chmod +x /app
USER user

我添加RUN chown user:user -R /app/和RUN chmod +x /app

运行docker build . 成功，但我仍然遇到权限问题

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"

看来您的 Django 项目运行良好，我已尝试重现您的错误，但无法得到它。

我的目录树：

.
|____app
| |____app
| | |____asgi.py
| | |______init__.py
| | |____settings.py
| | |____urls.py
| | |____wsgi.py
| |____manage.py
|____requirements.txt
|____Dockerfile
|____docker-compose.yml

requirements.txt

Django==3.1.5

Dockerfile：

FROM python:3.8-alpine

ENV PYTHONUNBUFFERED 1

COPY ./requirements.txt /requirements.txt
RUN pip install -r /requirements.txt

RUN mkdir /app
WORKDIR /app
COPY ./app /app

RUN adduser -D user
RUN chown user:user -R /app/
RUN chmod +x /app
USER user

Docker-compose：

version: "3"

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

我的步骤：

1. django-admin 启动项目应用程序
2. docker-compose 构建应用程序
3. 码头工人组成

浏览器：

我在想，你有另一种烫发问题，你有没有尝试从 MacOS 构建这个镜像？

试试下面的配置：

系统偏好设置 -> 安全和隐私 -> 隐私选项卡 -> 全盘访问（在左侧，在列表中的某处） -> 点击 + -> Docker 应用程序

希望对您和其他用户有所帮助。

Answer 2

不管什么原因改变我的

docker-compose.yml 来自

version: "3"

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

到

version: "3"

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

我将- ./app /app 修改为- ./app:/app。它解决了这个问题。如果有人有解释那就太好了。

感谢您的帮助。
