PROFILE
Kumar Vivek
Worked on the yugabyte/charts repository to enhance Kubernetes backup and restore workflows with Prometheus observability, focusing on data integrity and operational reliability. Delivered a robust feature set by updating Helm charts and implementing shell scripts to migrate Prometheus data directories, ensuring historical metrics were preserved during upgrades. Addressed critical bugs in certificate management by correcting certificate generation logic and improving SAN entry accuracy, which reduced TLS handshake errors. Further stabilized Istio TLS-enabled traffic by refining Kubernetes service configurations, enabling reliable pod communication. Utilized Bash, YAML, and Helm extensively, demonstrating a methodical approach to DevOps, system administration, and Kubernetes operations.

May 1, 2025Monthly summary for 2025-05 focused on stabilizing TLS-enabled Istio traffic in yugabyte/charts. Delivered a critical connectivity fix by renaming port labels from grpc-ybc-port to tcp-ybc-port in Kubernetes service configurations, enabling correct traffic deciphering between pods and from YBA to pods. The change mitigates Istio TLS failures for TLS-enabled universes and improves reliability in production deployments.
