	# - There is harmless warning:
	#
	# "[Warning] The requested image's platform (linux/arm64/v8) does not
	# match the detected host platform (linux/amd64) and no specific
	# platform was requested"
	#
	# It's hard to remove, perhaps, because we using 'build' and not 'buildx',
	# which requires more setup.
	#
	# - git clean is not necessarily on GA, but added so it's easier to copy-paste
	# Dockerfile for manual runs.
