When the build system runs the packages jobs for both architectures in parallel and has to create a new tag, tagging fails due to the race in the tagging. Move the git tagging to its own script that is run from a new top-level job that starts the packages jobs for both architectures.

# packages_tag() should be called w/ the positional INPUT parameters below.
|
|
|
|
# build tag automation stub.
|
|
# This script will update the versionfile with the OS packages version to build,
|
|
# and will add a version tag (see INPUT) to the scripts repo.
|
|
#
|
|
# PREREQUISITES:
|
|
#
|
|
# 1. SDK version is recorded in sdk_container/.repo/manifests/version.txt
|
|
# 2. SDK container is either
|
|
# - available via ghcr.io/flatcar-linux/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. Version of the TARGET OS image to build (string).
|
|
# The version pattern '(alpha|beta|stable|lts)-MMMM.m.p' (e.g. 'alpha-3051.0.0')
|
|
# denotes a "official" build, i.e. a release build to be published.
|
|
# Use any version diverging from the pattern (e.g. 'alpha-3051.0.0-nightly-4302') for development / CI builds.
|
|
# A tag of this version will be created in the scripts repo and pushed upstream.
|
|
#
|
|
#
|
|
# OPTIONAL INPUT:
|
|
#
|
|
# 2. coreos-overlay repository tag to use (commit-ish).
|
|
# Optional - use scripts repo sub-modules as-is if not set.
|
|
# This version will be checked out / pulled from remote in the coreos-overlay git submodule.
|
|
# The submodule config will be updated to point to this version before the TARGET SDK tag is created and pushed.
|
|
#
|
|
# 3. portage-stable repository tag to use (commit-ish).
|
|
# Optional - use scripts repo sub-modules as-is if not set.
|
|
# This version will be checked out / pulled from remote in the portage-stable git submodule.
|
|
# The submodule config will be updated to point to this version before the TARGET SDK tag is created and pushed.
|
|
#
|
|
# OUTPUT:
|
|
#
|
|
# 1. Updated scripts repository
|
|
# - version tag w/ submodules
|
|
# - sdk_container/.repo/manifests/version.txt denotes new FLATCAR OS version
|
|
# 2. "./skip-build" as flag file to signal that the build should stop
