Configuring Django with Nginx, uWSGI and Postgres on Docker - django

Question

I'm trying to setup a Django app on Docker with Nginx, uWSGI and Postgres. I found this great guide on setting up Compose for Django and Postgres: https://docs.docker.com/v1.5/compose/django/
However, now I need to add Nginx and uWSGI. I've tried using files of this repo (https://github.com/baxeico/django-uwsgi-nginx) with the Compose setup of the Docker docs but without succes, sadly.
This is what happens when I enter docker-compose run web:
Step 17 : RUN pip install -r /home/docker/code/app/requirements.txt

This is my Dockerfile:
from ubuntu:precise
run echo "deb http://us.archive.ubuntu.com/ubuntu/ precise-updates main restricted" | tee -a /etc/apt/sources.list.d/precise-updates.list
# update packages
run apt-get update
# install required packages
run apt-get install -y python python-dev python-setuptools python-software-properties
run apt-get install -y sqlite3
run apt-get install -y supervisor
# add nginx stable ppa
run add-apt-repository -y ppa:nginx/stable
# update packages after adding nginx repository
run apt-get update
# install latest stable nginx
run apt-get install -y nginx
# install pip
run easy_install pip
# install uwsgi now because it takes a little while
run pip install uwsgi
# install our code
add . /home/docker/code/
# setup all the configfiles
run echo "daemon off;" >> /etc/nginx/nginx.conf
run rm /etc/nginx/sites-enabled/default
run ln -s /home/docker/code/nginx-app.conf /etc/nginx/sites-enabled/
run ln -s /home/docker/code/supervisor-app.conf /etc/supervisor/conf.d/
# run pip install
run pip install -r /home/docker/code/app/requirements.txt
run cd /home/docker/code/app && ./manage.py syncdb --noinput
expose 80
cmd ["supervisord", "-n"]
And the docker-compose.yml:
db:
image: postgres
web:
build: .
command: python vms/manage.py runserver 0.0.0.0:8000
volumes:
- .:/code
ports:
- "8000:8000"
links:
- db
There are also files named nginx-app.conf, supervisor-app.conf, uwsgi_params and uwsgi.ini. These are all from the aforementioned repo. Requirements.txt contains Django 1.9.1, psycopg2 and requests.
If there is a better alternative to this Frankenstein project, I'd love to hear it.

On Ubuntu, make sure that python-dev and libpq-dev have been installed using apt-get, before trying to install psycopg2 using pip.
See the installation docs for more info.
