# Default build is CGO-free (NATS + JSON) — no librdkafka, gcc, or musl-dev, so
|
|
# it builds in a fraction of the time and cross-compiles to arm64/amd64 cleanly.
|
|
# BuildKit cache mounts keep the module + compile caches warm across builds.
|
|
#
|
|
# The builder always runs on the build host ($BUILDPLATFORM) and cross-compiles
|
|
# to $TARGETARCH, so multi-arch CI builds never run the Go compiler under QEMU.
|
|
#
|
|
# To include the optional Kafka backend, build with --build-arg GO_TAGS=kafka
|
|
# (adds librdkafka + CGO; slower, and CGO cannot cross-compile — build each arch
|
|
# on a native runner). Runtime selection is still by env
|
|
# (EVENTBUS_PROVIDER / CODEC_PROVIDER).
