docker run can't find application - nginx

Question

my project structure is:
/docker-test
/app
/static
....
/templates
....
-__init__.py
....
-nginx.conf
-supervisord.conf
-uwsgi.ini
-Dockerfile
-app.py
-requirements.txt
I normally run the app by going into /docker-test>python app.py
Dockerfile:
FROM python:2.7
# Install uWSGI
RUN pip install uwsgi
# Standard set up Nginx
ENV NGINX_VERSION 1.9.11-1~jessie

nginx.conf:
server {
location / {
include uwsgi_params;
uwsgi_pass unix:///tmp/uwsgi.sock;
}
}
uwsgi.ini:
[uwsgi]
wsgi-file=/app.py
socket = /tmp/uwsgi.sock
chown-socket = nginx:nginx
chmod-socket = 664
cheaper = 2
processes = 16
I am able to docker build and run without issue.
I get 500 error when trying to access the app in chrome:
no python application found

What is your current working directory? This just sounds like wsgi-file=/app.py should be wsgi-file=./app.py or you need to reference the correct absolute location such as wsgi-file=/deploy/app/app.py.
