# PYTHONFAULTHANDLER - https://docs.python.org/3/using/cmdline.html#envvar-PYTHONFAULTHANDLER
# PYTHONUNBUFFERED - send output straight to the terminal without hiding in the buffer
# PYTHONHASHSEED - a random value is used to seed the hashes of str and bytes objects, to prevent attackers from tar-pitting your application by sending you keys designed to collide
# PIP_NO_CACHE_DIR - cache the pip whl and tar files to speed up builder
# PIP_DISABLE_PIP_VERSION_CHECK - avoid warning that pip is out of date

# with the smallest number of layers possible (each COPY command creates a new layer)
RUN rm -rf .venv
EXPOSE 8081 8080
RUN poetry install

# CMD runs by default when no other commands are passed to a docker run directive from the command line.
CMD make start
