Worked on the cilium/cilium repository to enhance Kubernetes health check compatibility by migrating the heartbeat health check from the deprecated healthz endpoint to the newer readyz endpoint. This update ensured continued reliability of health monitoring across evolving Kubernetes versions while minimizing risk to existing deployments. The approach involved updating backend logic in Go to integrate with the readyz API and revising associated tests to maintain coverage and prevent regressions. Focused on backend development and API integration, the work prioritized business continuity and operational stability, addressing a key bug to align with Kubernetes best practices and maintain robust cluster health monitoring.
