Jan 1, 2025Month: 2025-01 | Performance summary for hmcts/cnp-flux-config Key features delivered: - Demo image policy enhancements for finrem-cos demo environment: introduced targeted image selection via PR-based filter patterns and an ascending order policy to ensure consistent, relevant demo images. Aligned with specific PR references to ensure the demo uses appropriate builds (PR-2076/PR-2069). Major bugs fixed: - Demo image policy stabilization by reverting to production image: removed custom tag filtering and deployed the latest production image to reduce deployment inconsistencies in the demo environment (commits include Reset demo image and Revert demo to prod:latest). Overall impact and accomplishments: - Increased reliability and determinism of the demo environment, enabling faster feedback and reduced manual intervention. - Improved alignment between demo scenery and target PR builds, reducing the risk of showcasing outdated or mismatched images. - Strengthened release discipline with clear rollback paths and version-controlled policy changes. Technologies/skills demonstrated: - Git-based release management, PR-driven image selection, policy-driven configuration management, and rollback readiness in a Flux-backed config repository. - CI/CD alignment and reproducible demo pipelines through explicit PR references and deterministic image policies.

Nov 1, 2024November 2024 focused on enabling production-grade overdue draft order notifications in hmcts/cnp-flux-config, stabilizing deployment config, and enriching the demo environment to validate end-to-end flows. Delivered the production cron to review overdue draft orders with configurable batch size and days since upload, established an initial daily run, and implemented a subsequent schedule correction. Fixed a deployment configuration issue (kustomization.yaml) to ensure the overdue cron is deployed with the correct config. Added demo support for overdue draft order notifications with enable/disable toggles and schedule controls to validate flows in the demo environment. Refined the demo image policy to align with production/testing, including tag filtering, timestamp-based extraction, and PR-specific image tags. These changes improve proactive stakeholder notifications, reduce deployment errors, and enhance testing fidelity across environments.
