# the GOARCH has no default value to allow the binary to be built according to the host where the command
# was called. For example, if we call make docker-build in a local env which has the Apple Silicon M1 SO
# the docker BUILDPLATFORM arg will be linux/arm64 when for Apple x86 it will be linux/amd64. Therefore,
# by leaving it empty we can ensure that the container and binary shipped on it will have the same platform.

# VV: Running the autoconf custom_experiment in the same container as the operator
# works best with python 3.12.7.
# If you plan to solely use the operator to request the recommendeations off of an 
# REST API endpoint then you can use a distroless image here as well as skip installing
# ado and its autoconf custom_experiment
