Monthly work summary for 2025-08 focusing on stabilizing CI for the yawol project by updating Earthly tooling and aligning the GitHub Actions runner image. No major feature regressions; CI reliability improvements dominated the month.

January 2025 — Gardener (stackitcloud/gardener): Implemented ControllerInstallations finalizer cleanup optimization by replacing manual finalizer removal with a controller-runtime watch. Finalizers (seedfinalizer) are now dropped promptly once all related ControllerInstallations are deleted, reducing cleanup latency and increasing reliability of resource lifecycle. This strengthens cluster reconciliation stability and reduces risk of stuck resources. Commit 5b8dc4acce134a5c814c8c803e7b2cb8a0e08efb (#10989).

In 2024-12, stabilized the gardener development workflow by fixing a permission-denied blocker in the development build and excluding a problematic directory from the dev make target. The change improves reliability of dev setup, accelerates onboarding, and reduces setup time.

Month: 2024-11. Delivered a portability enhancement for the tcp-timeout test in stackitcloud/yawol to run reliably across different shell environments. The test now uses a delayed message send to force a connection closure on the sending side, improving reliability when using nc. This aligns with CI stability goals and reduces flaky test results.

October 2024 monthly summary for stackitcloud/yawol: Implemented Loki log proxy support with annotation and promtail config injection, released yawol Helm chart 0.29.0 to align with the yawol-controller release, and fixed Load Balancer hash calculation to ignore proxyUrl when not set, including regression tests to prevent future issues. These changes improve log observability via proxy routing, release readiness, and hash stability across configurations, delivering tangible business value through more predictable deployments and secure log delivery.
