    listen 80;

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;

        if (!-f $request_filename) {
            proxy_pass http://app_server;
            break;

First you need to install virtualenv on the server

Build script:

echo "Start build scripts"

PYENV_HOME=$WORKSPACE/.venv/
if [ ! -d $PYENV_HOME ]; then
        virtualenv --no-site-packages $PYENV_HOME
fi
. $PYENV_HOME/bin/activate
pip install --quiet -r requirements.txt --download-cache=/tmp/$JOB_NAME

echo "END build scripts"
