This is my first try using the source-2-image tool to get a skeleton django up and running.

These steps were done on a mac Prerequisites:

• Python 3.5 installed
• Docker for Mac installed
• s2i installed

mkdir first-s2i-python-app
cd first-s2i-python-app
virtualenv ve

pip install Django Gunicorn
pip freeze > requirements.txt

django-admin startproject helloworld .
mv helloworld/wsgi.py .

See Notes below as to why we move the wsgi.py file around

s2i build . centos/python-35-centos7 first-s2i-python-app-image

docker run -p 8080:8080 first-s2i-python-app-image

and then you should be able to see "It Worked!" if you load http://127.0.0.1:8080

I have learned that to invoke some of automatic wiring of s2i for django projects, the following files must be at the root of the git repo:

• requirements.txt
• manage.py
• wsgi.py

Since we put the wsgi.py file at the root of the repo and we have specified Gunicorn in the requirements.txt file, then when running the image, a default Gunicorn server is used.

Had we not put either of the two prequisties in place, then s2i would have used python manage.py runserver to host the web application
