Worked on the prometheus-community/helm-charts repository to deliver runtimeClassName support for Prometheus pods deployed via Helm charts. The solution involved updating YAML templates, specifically deploy.yaml and sts.yaml, to conditionally inject the runtimeClassName field based on user input in values.yaml. This approach enables users to specify custom runtime classes, improving compatibility with diverse Kubernetes environments and supporting policy-driven pod isolation. The work was implemented using Helm and Kubernetes, focusing on maintainability and traceability through a linked commit. No major bugs were addressed during this period, with stability maintained while enhancing multi-tenant readiness and upgrade flexibility for Helm chart users.
