# We need gcc, build-essential and git to install our requirements but we
# don't need them when run the application so we can selectively copy artifacts
# from this stage (compile-image) to second one (runtime-image), leaving
# behind everything we don't need in the final build.

# This is useful when the application crashes before writing messages stuck in the buffer.
# Has a minor performance loss. We don't have many log messages so probably makes zero difference.
