# WARNING: THIS DOCKERFILE IS NOT INTENDED FOR PRODUCTION USE OR DEPLOYMENT.
#
# BASE_IMAGE: the Docker Hardened Image that Python comes from. Both the build stage and the final
# image are based on it, so Python is never compiled during the build.
#
# The default is Airflow's public mirror of the upstream "dhi.io/python" image, so building needs no
# registry credentials. The upstream image itself requires a "docker login dhi.io".
#
# The FIPS-validated variants require a paid Docker subscription and cannot be mirrored or made the
# default, but you can build a FIPS-compliant image by pointing the build at one:
#   docker build . --build-arg BASE_IMAGE="dhi.io/python:3.13.16-debian13-fips-dev"
ARG BASE_IMAGE="ghcr.io/apache/airflow/base/python:3.13.16-debian13-dev"
