# Multi-arch overrides for the release pipeline. Layered on top of
# docker-compose.yml: bake reads the compose file (https://docs.docker.com/build/bake/compose-file/),
# inherits build context/args/image tags, and we override `platforms` here.
#
# Compose itself stays host-arch / single-platform so `docker compose build`
# loads intermediates into the local image store, letting downstream
# `FROM doublewick/boxball:<stage>-${VERSION}` resolve locally instead of
# pulling stale registry tags. Multi-arch needs `--push` (buildx can't `--load`
# a manifest list), so it lives here and runs from the release workflow.
#
# Usage (release; needs DH creds — PLE-357/358):
#   docker buildx bake --file docker-compose.yml --file docker-bake.hcl --push multiarch
#
# Local dry-run (single-platform, validates HCL parses + targets resolve):
#   docker buildx bake --file docker-compose.yml --file docker-bake.hcl --print multiarch

# Most targets multi-arch.

# The compose `<stage>-latest` twins (extract-latest, ddl-latest, …) are
# intentionally absent from the `multiarch` group. PLAN.md M2 requires both
# `<stage>-${VERSION}` and `<stage>-latest` on Docker Hub, but rebuilding the
# full chain twice is wasteful. `.github/workflows/release.yml` retags via
# `docker buildx imagetools create` after `bake-push` lands the versioned
# manifest lists — cheap, byte-identical, and preserves the manifest list's
# multi-arch shape.
