# Dockerfile for building Eclipse Chariott Intent Brokering service container
# with valgrind
#
# This Dockerfile utilizes a two step build process. It builds Chariott Intent
# Brokering with statically linked dependencies (using musl vs. glibc to
# accomplish this) for a specific architecture such that we can utilize a
# scratch container without further dependencies for our final container,
# minimizing container size.
