Worked on the prometheus-community/helm-charts repository to deliver standardized resource labeling for the Prometheus JSON Exporter Helm chart. Introduced support for commonLabels by updating template logic in _helpers.tpl and deployment.yaml, enabling consistent label application across all chart resources. Added a commonLabels field to values.yaml, allowing centralized management of labels and reducing manual overhead when deploying across Kubernetes clusters. This approach improved governance, observability, and automation by making resource selection and monitoring more efficient. The work was implemented using Helm and Kubernetes, with YAML as the primary language for configuration, focusing on maintainability and environment parity across deployments.
