Makefile

# This file is a helper script to make repetitive build actions easier
# Invoking `make docker` will build the docker image.
# `make docker-nc` will build the docker image without using the Docker cache.
# `make secrets` will generate secrets for group 1234.
# `make firmware` will make the firmware image.
# `make clean` will remove build artifacts, both in the firmware
# directory and the final output directory.

	docker build -t build-hsm ./firmware/

	docker build --no-cache -t build-hsm ./firmware/
