# packages_build() should be called w/ the positional INPUT parameters below.
|
|
|
|
# OS image binary packages build automation stub.
|
|
# This script will use an SDK container to build packages for an OS image.
|
|
#
|
|
# 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. SDK container is either
|
|
# - available via ghcr.io/flatcar/flatcar-sdk-[ARCH]:[VERSION] (official SDK release)
|
|
# OR
|
|
# - available via build cache server "/containers/[VERSION]/flatcar-sdk-[ARCH]-[VERSION].tar.gz"
|
|
# (dev SDK)
|
|
#
|
|
# INPUT:
|
|
#
|
|
# 1. Architecture (ARCH) of the TARGET OS image ("arm64", "amd64").
|
|
#
|
|
#
|
|
# OPTIONAL INPUT:
|
|
#
|
|
# 2. 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.
|
|
#
|
|
# 3. 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.
|
|
#
|
|
# 4. A file ../scripts.patch to apply with "git am -3" for the scripts repo.
|
|
#
|
|
# OUTPUT:
|
|
#
|
|
# 1. Exported container image "flatcar-packages-[ARCH]-[VERSION].tar.gz" with binary packages
|
|
# pushed to buildcache (for use with tests).
|
|
# 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.
