run django in docker container

Question

I'm trying to make a simple example of Django app running in docker container.

using this image https://hub.docker.com/_/django/ just for simplicity. Don't tell me please that i shouldn't use it in production :) app is very simple and i'm ok with using very basic Django server.

So, the problem is i'm always getting this error when trying to run the container image

C:\Users\slipo\PycharmProjects\simple_blog>docker run -p 8000:8000 my-blog
python: can't open file './manage.py runserver 0.0.0.0:8000 --settings=mysite.settings.prod': [Errno 2] No such file or directory

however, ./manage.py and mysite.settings.prod both definitely existing in container.

container creation log showing the file exists:

Step 7 : RUN ls -a

Dockerfile:

FROM django

EXPOSE 8000

ADD . /simple_blog
WORKDIR /simple_blog

RUN pip install -r requirements.txt
RUN pip install django-tinymce

RUN ls -a

CMD [ "python", "./manage.py runserver 0.0.0.0:8000 --settings=mysite.settings.prod" ]

Thank you.

Answer 1

can't open file './manage.py runserver 0.0.0.0:8000 --settings=mysite.settings.prod'

This is telling you that it is treating that entire string as a single filename.

I assume something like this works:

CMD [ "python", "./manage.py", "runserver", "0.0.0.0:8000", "--settings=mysite.settings.prod" ]

Answer 2

Try to execute this code.

CMD [ "python", "../manage.py runserver 0.0.0.0:8080 --settings=my_site.settings.prd"
