# 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 and torcx artefacts.
|
|
#
|
|
# 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.
|
|
#
|
|
# OUTPUT:
|
|
#
|
|
# 1. Exported container image with OS image, dev container, and related artifacts at
|
|
# /home/sdk/image/[ARCH], torcx packages at /home/sdk/torcx
|
|
# named "flatcar-images-[ARCH]-[FLATCAR_VERSION].tar.gz"
|
|
# 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.
