Django 2.0.9 - docker-compose up - creation of super user

Good morning.

Can anyone help me with the following problem:

I'm creating a docker-compose from a Django application . I need to create a super user at the moment of the command:

$ docker-compose up

However, I'm not getting it, here is my Dockerfile:

FROM python:3.6.7
ENV PYTHONUNBUFFERED 1

WORKDIR /code
ADD requirements.txt /code/
RUN pip install -r requirements.txt
ADD . /code/

COPY entrypoint.sh /entrypoint.sh
RUN chmod +x /entrypoint.sh

I tried to change to:

FROM python:3.6.7
ENV PYTHONUNBUFFERED 1

ENV DJANGO_DB_NAME=default
ENV DJANGO_SU_NAME=admin
ENV [email protected]
ENV DJANGO_SU_PASSWORD=mypass

RUN python -c "import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'projeto.settings'
import django
django.setup()
from django.contrib.auth.management.commands.createsuperuser import get_user_model
if get_user_model().objects.filter(username='$DJANGO_SUPERUSER_USERNAME'): 
    print 'Super user already exists. SKIPPING...'
else:
    print 'Creating super user...'
    get_user_model()._default_manager.db_manager('$DJANGO_DB_NAME').create_superuser(username='$DJANGO_SUPERUSER_USERNAME', email='$DJANGO_SUPERUSER_EMAIL', password='$DJANGO_SUPERUSER_PASSWORD')
    print 'Super user created...'"

WORKDIR /code
ADD requirements.txt /code/
RUN pip install -r requirements.txt
ADD . /code/

COPY entrypoint.sh /entrypoint.sh
RUN chmod +x /entrypoint.sh

But the super admin user was not created and none of the prints appeared in the terminal.

Also, below the file docker-compose.yml:

db:
  image: postgres
web:
  build: .
  command: chmod +x run_web.sh
  command: ./run_web.sh
  entrypoint: ./entrypoint.sh
  volumes:
    - .:/code
  ports:
    - "8000:8000"
  links:
    - db

run_web.sh:

#!/bin/bash

python manage.py runserver 0.0.0.0:8000

File entrypoint.sh:

#!/bin/sh

python manage.py makemigrations
python manage.py migrate
python manage.py collectstatic --noinput

exec "$@"

I tried to include the python manage.py createsuperuser command in the entrypoint.sh file, but the following error occurred at docker-compose up :

Superuser creation skipped due to running in a TTY. You can run manage.py createsuperuser in your project to create one manually.
