Includes three commits expanding collection logic and introducing the sign-image-cosign-keyless task and keyless verify-conforma parameters. Commits: 7bd608de7af4c75e1a53129d23d40ed2c5b53227; a44bf53d82b7565e2be478a31270e916eb7d68a4; 13eda3f2751e250ae00a9de417bf92358020eb85. Major bugs fixed: - Release-service-catalog: Removed non-existent TIMEOUT parameter from verify-conforma configuration to prevent CI breakage, stabilizing the pipeline. Commit: 962a330d2d9b5fb5692f105fa5ee3a1edb175cf7. Overall impact and accomplishments: - Strengthened security posture with keyless cosign signing across CI/CD, reducing key management overhead and enabling more automated, compliant signing flows. - Expanded platform support with aarch64, ensuring secure builds for arm64-based environments. - Improved CI reliability by removing a breaking TIMEOUT parameter and aligning configs with actual YAML definitions. Technologies/skills demonstrated: - Dockerfile optimization, cosign-based signing, and keyless signing workflows. - CI/CD automation with Tekton-related parameter handling and tasks (collect-signing-params, sign-image-cosign-keyless, verify-conforma enhancements). - Cross-architecture support and YAML/config management for external-registry signing pipelines. - Focus on deliverables with clear commit trail for traceability.

February 2026: Delivered Cosign Binary Version 3 with Multi-Identity Support in konflux-ci/release-service-utils. Added support for signing with multiple container identities per call while preserving Cosign v2 compatibility by introducing v3 as a separate file. This enables more flexible and secure CI/CD signing workflows, reduces manual steps, and improves traceability. Key commit: 2d8cf62ad035c78b16c10f1c9b5308bdedb82305 (feat(RELEASE-1976): added cosign 3 binary).

January 2026: Key release-service improvements in konflux-ci/release-service-utils. Delivered a reliability fix for batch signing by updating pubtools-sign to v1.0.6, stabilizing the signing stage of the release pipeline and reducing intermittent failures. Commit 13e379cb498293f8f7b8b9c84c57d9e8ab141be2 (chore(RELEASE-2183): update pubtools-sign to 1.0.6; PR #637). This work improves release velocity, auditability, and rollback resilience.

December 2025: Delivered major improvements to signing workflows and signature processing in konflux-ci/release-service-catalog. Implemented multi-key signing support and refined Pyxis server handling to support production-internal and stage-internal configurations, boosting reliability and throughput. Optimized resource usage by deduplicating signature lookups and moving filtering to a scalable path, reducing memory pressure and enabling parallel processing across internal requests. These changes translate to faster builds, lower failure rates in signing, and more predictable performance in CI pipelines.

November 2025 monthly summary: Delivered targeted improvements across release-service-utils and release-service-catalog to strengthen signature management, improve filtering across multiple signing keys, and enhance robustness of the signature workflow. These changes improved CI reliability, reduced manual intervention, and increased maintainability of the signing process.

Concise monthly summary for 2025-10 focused on business value and technical outcomes across two repos: konflux-ci/release-service-catalog and konflux-ci/release-service-utils. The month emphasizes modular pipeline design, reliable signing tooling, and improved parameter management for release workflows.

July 2025 monthly summary for scoheb/release-service-catalog: Primary focus on reliability and security improvements in the image signing workflow. Delivered a critical fix to use the correct source digest for signing source-tag digests in rh-sign-image task; updated tests to reflect the corrected behavior. No new user-facing features this month; the work strengthens image integrity verification and reduces risk of incorrect signing in downstream deployments.

June 2025 performance summary: Delivered security and reliability improvements in release tooling across two repositories. Upgraded PubTools dependencies in the Dockerfile for konflux-ci/release-service-utils and implemented a batching-enabled image signing/upload pipeline in scoheb/release-service-catalog using pubtools-sign and pubtools-pyxis. Replaced local retry logic with PubTools error handling to reduce flaky retries and improve throughput, accelerating secure releases.

April 2025 monthly summary for konflux-ci/release-service-utils. Key focus: security enablement and build reproducibility in the release service utilities. Delivered two major improvements that enhance security, reliability, and deployment consistency across CI pipelines.

March 2025 monthly summary for scoheb/release-service-catalog focusing on efficient parallel image signing with deduplication in rh-sign-image-cosign. The changes enable parallel signing with a configurable concurrency limit, skip signing when a signature already exists, reducing redundant work and accelerating the release-signing workflow. This contributed to higher throughput in the release-service-catalog signing pipeline and reduced overall build times.

January 2025 highlights for scoheb/release-service-catalog: Implemented parallel execution for the rh-sign-image-cosign signing task and added a guard to only sign images if a signature for the given identity and digest does not already exist, significantly improving performance and reducing redundant work. Updated documentation and tests to reflect the new workflow (README, YAML definition, and mock testing scripts). While no distinct bugs were reported this month, the reliability and scalability of the signing pipeline were enhanced through idempotent operations and parallel processing. This aligns with our goals of faster deployments, lower operational costs, and improved maintainability.
