What is Django?

Django is a free and open source web application framework, written in Python, which follows the model-view-controller architectural pattern. Django's primary goal is to ease the creation of complex, database-driven websites with an emphasis on reusability and "pluggability" of components.

How to use this image

Create a Dockerfile in your Django app project

FROM django:onbuild

Put this file in the root of your app, next to the requirements.txt.

This image includes multiple ONBUILD triggers which should cover most applications. The build will COPY . /usr/src/app, RUN pip install, EXPOSE 8000, and set the default command to python manage.py runserver.

You can then build and run the Docker image:

$ docker build -t my-django-app .
$ docker run --name some-django-app -d my-django-app

You can test it by visiting http://container-ip:8000 in a browser or, if you need access outside the host, on http://localhost:8000 with the following command:

$ docker run --name some-django-app -p 8000:8000 -d my-django-app

Without a Dockerfile

Of course, if you don't want to take advantage of magical and convenient ONBUILD triggers, you can always just use docker run directly to avoid having to add a Dockerfile to your project.

$ docker run --name some-django-app -v "$PWD":/usr/src/app -w /usr/src/app -p 8000:8000 -d django bash -c "pip install -r requirements.txt && python manage.py runserver 0.0.0.0:8000"

Bootstrap a new Django Application

If you want to generate the scaffolding for a new Django project, you can do the following:

$ docker run -it --rm --user "$(id -u):$(id -g)" -v "$PWD":/usr/src/app -w /usr/src/app django django-admin.py startproject mysite

This will create a sub-directory named mysite inside your current directory.
