# ENTRYPOINT for the perfetto-ui-builder Docker image, invoked from
# infra/ui.perfetto.dev/cloudbuild*.yaml.
#
# $1 is the branch name (or 'autopush' literal from cloudbuild.yaml).
# Cloud Build has already placed us on the SHA that fired the trigger,
# so we build from HEAD without any explicit checkout.
#
# Branches autopush/canary/stable map 1:1 to channels of the same name.
# Any other branch (i.e. a release branch) maps to the 'release' mode,
# which uploads /v<version>/ only and does NOT touch the shared root
# index.html or service_worker.
#
# See go/perfetto-ui-autopush for end-to-end docs.
