To protect against upstream download failures for gperf and busybox, implement ORAS-based caching to GHCR. This adds: - download-with-oras-cache.sh: Core helper for downloading with cache - populate-oras-tarball-cache.sh: Script to manually populate cache - warn() function to lib.sh for consistency Modified build scripts to: - Try ORAS cache first (from ghcr.io/kata-containers/kata-containers) - Fall back to upstream download on cache miss - Automatically push to cache when PUSH_TO_REGISTRY=yes The cache is automatically populated during CI builds, and parallel architecture builds check for existing versions before pushing to avoid race conditions. Forks benefit from upstream cache but can override with their own: ARTEFACT_REPOSITORY=myorg/kata make agent-tarball Generated-By: Cursor IDE with Claude Signed-off-by: Fabiano Fidêncio <ffidencio@nvidia.com>
Packaging scripts
This directory contains useful packaging scripts.
configure-hypervisor.sh
This script generates the official set of QEMU-based hypervisor build configuration options. All repositories that need to build a hypervisor from source MUST use this script to ensure the hypervisor is built in a known way since using a different set of options can impact many areas including performance, memory footprint and security.
Example usage:
$ configure-hypervisor.sh qemu
