# This Dockerfile is incorporating a production-grade application server

# Set the base container. Note: we don't use the smaller alpine container as
# pip needs a C compiler to install uwsgi from the dependencies
FROM python:3.8

# Create a user and group to use within the container
RUN groupadd -r apiserver && useradd --no-log-init -r -g apiserver apiserver
# Copy all of the current (and sub) dir into the container during build
ADD . /code
# Define the starting working directory within the container
WORKDIR /code
# While building, install python dependencies
RUN pip install -r requirements.txt && pip install -r requirements.uwsgi.txt

# Next we set defaults for some of the envvars
# NOTE: You MUST set more than these! See .env.sample file for a list.
ENV SERVER_PORT=9090

# Give a hint to docker where the service exposes
EXPOSE ${SERVER_PORT}

# Define the user to be used inside when running the container
USER apiserver:apiserver

# This defines the command that will run the actual starting process within the container
CMD ["uwsgi", "uwsgi.ini"]
