Walkthrough

The configuration for the Grafana sidecar in the kube-prometheus-stack Helm chart was updated to change the datasources resource type from "configmap" to "both," enabling the sidecar to manage both ConfigMaps and Secrets for datasources.

Changes

File(s)	Change Summary
charts/base-cluster/templates/monitoring/kube-prometheus-stack/_grafana-config.yaml	Updated Grafana sidecar datasources resource type from "configmap" to "both".

Poem

A hop and a skip, a config reborn,
Grafana now listens to secrets at dawn.
No longer just maps, but secrets as well,
The sidecar now watches where datasources dwell.
In clusters and charts, the changes are neat—
More sources to gather, more data to eat!

97-97: Verify RBAC and chart metadata updates
With Secrets now in scope, please ensure the sidecar’s RBAC rules grant get, list, and watch on secrets (in addition to configmaps). Also update the chart’s documentation (README or values reference) and bump the chart version in Chart.yaml to reflect this new capability.
