# Set the port on which the app runs; make both values the same.
#
# IMPORTANT: When deploying to Azure App Service, go to the App Service on the Azure 
# portal, navigate to the Applications Settings blade, and create a setting named
# WEBSITES_PORT with a value that matches the port here (the Azure default is 80).
# You can also create a setting through the App Service Extension in VS Code.

# Indicate where uwsgi.ini lives
ENV UWSGI_INI uwsgi.ini

# Tell nginx where static files live. Typically, developers place static files for
# multiple apps in a shared folder, but for the purposes here we can use the one
# app's folder. Note that when multiple apps share a folder, you should create subfolders
# with the same name as the app underneath "static" so there aren't any collisions
# when all those static files are collected together.
ENV STATIC_URL /hello_app/static

# Set the folder where uwsgi looks for the app
WORKDIR /hello_app

# Copy the app contents to the image
COPY . /hello_app

# If you have additional requirements beyond Flask (which is included in the
# base image), generate a requirements.txt file with pip freeze and uncomment
# the next three lines.
#COPY requirements.txt /
#RUN pip install --no-cache-dir -U pip
#RUN pip install --no-cache-dir -r /requirements.txt
