19 Commits • 4 Features
Mar 1, 2026March 2026 (flightctl/flightctl) delivered substantial reliability and security enhancements across greenboot, healthcheck packaging, git config testing, and tooling, delivering measurable business value through safer upgrades, reduced operational risk, and improved test coverage. Key outcomes include safer rollback during greenboot updates with atomic boot ID capture, ensuring that third-party health-check failures do not trigger OS rollbacks, and extended end-to-end coverage around rollback and healthcheck logging. Packaging and wiring changes unconditionally enable greenboot-healthcheck via RPM post-install and remove containerfile-based enablement, simplifying deployment and reducing configuration drift. The git config end-to-end test harness improvements added Polarion IDs, validated updates, and enabled dynamic environment verification for traceability. The tooling upgrade to Go 1.25.8 and related lint/base-image updates addressed CVEs and improved performance and security. End-to-end test reliability was improved with stabilization of systemd wait handling, including a daemon-reload workflow, reducing flaky behavior in memory-snapshot rollbacks. These efforts collectively improve product stability, security, and deployment confidence, while demonstrating strong ownership of core platform components.

Jan 1, 2026January 2026 (2026-01) focused on reliability, observability, and deployment tooling for flightctl/flightctl. Key outcomes include robust connectivity status reporting via sd_notify integrated with bootstrap, two-phase polling, stability window, and socket safety; Greenboot rollback testing and polling improvements with E2E verification; version pinning of Greenboot to 0.15.x to avoid issues; deployment tooling upgrades (virsh console) and related doc updates; and systemd hardening with nil-checks and improved error handling. These efforts improve update reliability, reduce risk of failed rollbacks, increase observability, and accelerate safe deployments.

Dec 1, 2025December 2025 monthly summary for flightctl/flightctl: Delivered critical features improving deployment flexibility, health visibility, and logging robustness. Key initiatives include: 1) INJECT_CONFIG parameter for agent-vm build enabling conditional config injection into qcow2 images; 2) Health checks enhancements with a shared library, a new health subcommand for GreenBoot integration, pre-rollback debug collection, and modernization of the health package; 3) Robust audit logger fallback to 'unknown' when agent version is missing to improve logging resilience. These changes reduce deployment risk, improve incident response, and demonstrate proficiency in Go, CLI tooling, and systemd-integrated patterns.
