[SOLVED] Permission denied: '/app/manage.py' Docker

Issue

I'm having a permissions issue when trying to run my docker-compose command

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

ERROR:

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

I've done some research and found a similar issue here: docker-compose , PermissionError: [Errno 13] Permission denied: '/manage.py'

However I think I'm doing something wrong when trying to change permissions in my Dockerfile

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

I add RUN chown user:user -R /app/ and RUN chmod +x /app

running docker build . works succesfully however I still keep getting permissions issue

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"

Solution

For whatever reason changing my

docker-compose.yml from

version: "3"

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

To

version: "3"

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

I modified - ./app /app to - ./app:/app. It fixed the issue. If anyone has an explanation that would be great.

Thanks for the help.
