Packing a Django 1.8.19 project where the Dockerfile helps download the related dependencies and set the password of superuser. The Django project is created from the tutorial.
Solving the problem of setting the password of the superuser in the Dockerfile. The command python3 manage.py createsuperuser --noinput only receives username and email while the password cannot be customized. Note that the superuser can also be created when the docker container starts running and opened in terminal (ref), but the question here focuses on solving this in the Dockerfile.
One way of setting the superuser is using the package django-createsuperuserwithpassword, but the required framework of it is at least Django 1.11.
At the CMD part, I create the superuser by using python3 manage.py createsuperuser and then use the changesuperuserpw.py to reset the password I want. The default username, password, and email are stored as ENV variables, so that I can overwrite them as I create the docker container.
FROM python:3.7
EXPOSE 8000
WORKDIR /django_admin
COPY . .
ENV PASSWORD 000
ENV USERNAME abc
ENV EMAIL [email protected]
ENV PYTHONUNBUFFERED=1
ENV DJANGO_SETTINGS_MODULE mysite.settings
RUN pip3 install -r requirements.txt --no-cache-dir
CMD python3 manage.py migrate; \
python3 manage.py createsuperuser --noinput --username $USERNAME --email $EMAIL; \
python3 changesuperuserpw.py -n $USERNAME -p $PASSWORD; \
python3 manage.py runserver 0.0.0.0:8000Therefore, the command which builds the docker image is
docker run -it -p [port on your computer]:8000 \
-e USERNAME=[your superuser name] \
-e PASSWORD=[your superuser password] \
-e EMAIL=[your superuser email] \
[image_name]
