April 2026 — openshift/release: OpenShift CI Security Enhancement delivering Sigstore verification across CI pipelines. Introduced the OPENSHIFT_INSTALL_EXPERIMENTAL_DISABLE_IMAGE_POLICY environment variable to CI job configurations to enable Sigstore signature verification in 4.22 stable builds. No major bugs fixed in this scope. Impact: strengthened CI security and artifact integrity across pipelines, enabling better governance and compliance with supply-chain security standards. Technologies/skills demonstrated: Sigstore integration, CI/CD security, environment-variable based feature toggles, and traceable changes via commits, enabling auditable security improvements. Key business value includes reduced risk of tampered artifacts, faster detection of integrity issues, and improved overall trust in automated builds.

March 2026 (2026-03) monthly summary for openshift/release. Key features delivered include: (1) OpenShift installer tech preview for RHCOS 10, with the installer job renamed from e2e-aws-ovn-rhel10-devpreview to e2e-aws-ovn-rhcos10-techpreview across multiple configuration files, signaling the tech-preview phase. (2) Periodic DNS testing for AWS and Azure in CI/CD, including configuration and environment variables to improve DNS reliability across cloud platforms.

Feb 2026 monthly summary for openshift/release: Delivered Image Policy Flexibility for Install and Upgrade. Implemented testing support for unsigned release images by temporarily disabling the image signature policy during installation and restoring the standard policy during upgrades to preserve upgrade path integrity. This was implemented via two commits: 6e0864f8b75e178b797d47739eaefaf64491dddc (set OPENSHIFT_INSTALL_EXPERIMENTAL_DISABLE_IMAGE_POLICY to true in install) and ad9b9f54db84b3f1cab1d60011eff4e99d66153b (unset the env var to avoid adding the CVO override for the stable 4.21 upgrade path). Major bug fix: prevented unintended CVO override in stable upgrades by unsetting the env var, ensuring upgrade path integrity. Overall impact: expanded testing coverage for unsigned images, reduced upgrade risk, and improved CI reliability. Technologies/skills demonstrated: environment variable management, feature toggles, upgrade/install flow, change traceability across commits.
