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

Question

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 ."

This produces the error:

    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()
  File "/usr/local/lib/python3.7/site-packages/django/core/management/__init__.py", line 375, in execute
    self.fetch_command(subcommand).run_from_argv(self.argv)
  File "/usr/local/lib/python3.7/site-packages/django/core/management/base.py", line 323, in run_from_argv
    self.execute(*args, **cmd_options)

    output = self.handle(*args, **options)
  File "/usr/local/lib/python3.7/site-packages/django/core/management/commands/startproject.py", line 20, in handle
    super().handle('project', project_name, target, **options)

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

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

My 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"

I applied the solution suggested in this Stack Overflow thread, but it didn't work.

I'm using Ubuntu 18.04.

I got here searching for PermissionError: [Errno 13] Permission denied: so i'll just leave this here.

note: the below answer doesn't work for multi user systems ... see this answer instead for another possible solution

If you want to set it and forget it for 1 user, your own user ... here's what I have on my dev machine.

I didn't own the unix socket, so I chowned it. ( this got it working straight away )

sudo chown $(whoami):$(whoami) /var/run/docker.sock

Another, more permanent solution for your dev environment, is to modify the user ownership of the unix socket creation. This will give your user the ownership, so it'll stick between restarts:

sudo nano /etc/systemd/system/sockets.target.wants/docker.socket

docker.socket:

[Unit]
Description=Docker Socket for the API

[Socket]
ListenStream=/var/run/docker.sock
SocketMode=0660
SocketUser=YOUR_USERNAME_HERE
SocketGroup=docker

[Install]
WantedBy=sockets.target

Again another less hacky solution: https://stackoverflow.com/a/70124863/2026508

Answer 2

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

RUN adduser -D dockuser
USER dockuser

Hence your container will start with user dockuser which does not seem to have proper permissions to run /manage.py.

You can either

• remove the above mentioned lines where you create and point to dockuser.

OR

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

I have answered such similar question here.
