# Build
# the GOARCH has not a default value to allow the binary 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.
#
# Note, we include cache mounts to speed up incremental builds. The directories
# we mount are the cache directories present in the container. These can be
# found via `go env | grep CACHE`.
