cmd/buildlet/stage0/Makefile

# Common targets:
#
#  - compile: build all stage0 binaries (but do not upload)
#  - upload: build and upload all stage0 binaries to prod
#  - dev-upload: build and upload all stage0 binaries to dev cluster
#  - docker: build golang/buildlet-stage0 Docker image (but do not push)
#
# Individual targets:
#
#  - buildlet-stage0.linux-arm64: build stage0 binary for linux-arm64 (but do not upload)
#  - upload.linux-arm64: build stage0 binary for linux-arm64 and upload to prod
#  - dev-upload.linux-arm64: build stage0 binary for linux-arm64 and upload to dev cluster

#
# The stage0 binaries are typically baked into VM images and container
# images and are NOT downloaded per build or VM/container start-up.
# The only reason we upload them to GCS is because that's where the
# automated VM/container creation scripts download them from.
