April 2026 monthly summary across art-tools, aos-cd-jobs, and release. Focused on reliability, automation, and performance to deliver business value with minimal toil. Highlights include:

During March 2026, the OpenShift engineering teams delivered a focused set of reliability, security, and orchestration improvements across plashet packaging, signing, release workflows, and CI/CD pipelines. Key work ranged from hardening plashet packaging (and removing remote-heritage bloat) to tightening CLI reliability and enabling per-arch signing coverage, while also strengthening build orchestration and release determinism. Key features delivered included: - Plashet cleanup and packaging optimization: remote purge of old plashet revisions (keeping the 3 most recent) and packaging/exclude-package handling improvements; RHEL-8 plashets were updated to exclude kernel packages for 4.13+ to reduce metadata bloat. - Plashet exclude-package CLI reliability fix: correct placement of --exclude-package in the CLI, preventing runtime errors and filtering conflicting flags. - Assembly labeling for microshift-bootc builds: added assembly labels and support for extra labels via CLI for better traceability. - Build orchestration improvements: seed RPM lockfiles, expose build result URLs, improve parent-image scheduling, and optimize createrepo_c by skipping SQLite database generation. - Signing and release reliability: fixed arch-wide signing discovery, introduced batch retries for cosign signings, and added completeness validation before assembly to ensure all required RPMs are signed and present. - Release payload consistency and BuildRepo correctness: tightened payload-only checks and ensured BuildRepo uses the correct branch when seed/phase transitions occur. - CI/CD and infrastructure enhancements: sequential test runs in Jenkins, a new seed-lockfile Jenkins job, and logging/maintenance refinements to reduce toil ( includes cleanup of outdated logging groups). - Cross-repo impact: carry-forward improvements across openshift-eng/art-tools, openshift/release and openshift-eng/aos-cd-jobs to improve deployment reliability and governance. Overall impact: these changes reduce build times, improve artifact security, increase release determinism, and lower operational risk, enabling faster, safer delivery of OpenShift components to customers. Technologies/skills demonstrated: Koji-based build discovery, multi-arch release handling, cosign signing, createrepo_c metadata optimization, tenacity-based retries, CLI design with proper flag scoping, remote host scripting, and cross-repo collaboration.
