# DEPRECATED
This image is officially deprecated in favor of the standard python
image, and will receive no further updates after 2016-12-31 (Dec 31, 2016). Please adjust your usage accordingly.
For most usages of this image, it was already not bringing in django
from this image, but actually from your project's requirements.txt
, so the only "value" being added here was the pre-installing of mysql-client
, postgresql-client
, and sqlite3
for various uses of the django
framework.
For example, a Dockerfile
similar to the following would be a good starting point for a Django project using PostgreSQL:
FROM python:3.4
RUN apt-get update \
&& apt-get install -y --no-install-recommends \
postgresql-client \
&& rm -rf /var/lib/apt/lists/*
WORKDIR /usr/src/app
COPY requirements.txt ./
RUN pip install -r requirements.txt
COPY . .
EXPOSE 8000
CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]

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.
Image Variants
The django
images come in many flavors, each designed for a specific use case.
django:<version>
This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.
django:onbuild
This image makes building derivative images easier. For most use cases, creating a Dockerfile
in the base of your project directory with the line FROM django:onbuild
will be enough to create a stand-alone image for your project.
While the onbuild
variant is really useful for "getting off the ground running" (zero to Dockerized in a short period of time), it's not recommended for long-term usage within a project due to the lack of control over when the ONBUILD
triggers fire (see also docker/docker#5714
, docker/docker#8240
, docker/docker#11917
).
Once you've got a handle on how your project functions within Docker, you'll probably want to adjust your Dockerfile
to inherit from a non-onbuild
variant and copy the commands from the onbuild
variant Dockerfile
(moving the ONBUILD
lines to the end and removing the ONBUILD
keywords) into your own file so that you have tighter control over them and more transparency for yourself and others looking at your Dockerfile
as to what it does. This also makes it easier to add additional requirements as time goes on (such as installing more packages before performing the previously-ONBUILD
steps).
