# image_build() should be called w/ the positional INPUT parameters below.
# Binary OS image build automation stub.
# This script will build the OS image from a pre-built packages container.
#
# PREREQUISITES:
#
# 1. SDK version and OS image version are recorded in sdk_container/.repo/manifests/version.txt
# 2. Scripts repo version tag of OS image version to be built is available and checked out.
# 3. Flatcar packages container is available via build cache server
# from "/containers/[VERSION]/flatcar-packages-[ARCH]-[FLATCAR_VERSION].tar.gz"
# or present locally. Container must contain binary packages.
#
# INPUT:
#
# 1. Architecture (ARCH) of the TARGET OS image ("arm64", "amd64").
#
# OPTIONAL INPUT:
#
# 1. SIGNER. Environment variable. Name of the owner of the artifact signing key.
# Defaults to nothing if not set - in such case, artifacts will not be signed.
# If provided, SIGNING_KEY environment variable should also be provided, otherwise this environment variable will be ignored.
#
# 2. SIGNING_KEY. Environment variable. The artifact signing key.
# Defaults to nothing if not set - in such case, artifacts will not be signed.
# If provided, SIGNER environment variable should also be provided, otherwise this environment variable will be ignored.
#
# 3. A file ../scripts.patch to apply with "git am -3" for the scripts repo.
#
# OUTPUT:
#
# 1. OS image, dev container, and related artifacts pushed to buildcache.
# 2. "./ci-cleanup.sh" with commands to clean up temporary build resources,
# to be run after this step finishes / when this step is aborted.
# 3. If signer key was passed, signatures of artifacts from point 1, pushed along to buildcache.
# 4. DIGESTS of the artifacts from point 1, pushed to buildcache. If signer key was passed, armored ASCII files of the generated DIGESTS files too, pushed to buildcache.
