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>

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
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 don't seems to have proper permissions to run /manage.py.
You can either
dockuser.OR
dockuser using chown and chmod commands in your dockerfile for /manage.py file.I have answered such similar question here.
I had the same issue and solved it by adding my user to the docker group:
$ sudo usermod -aG docker $(whoami)
