If the parameter `sidecar.dashboards.enabled` is set, a sidecar container is deployed in the grafana pod. This container watches all config maps in the cluster and filters out the ones with a label as defined in `sidecar.dashboards.label`. The files defined in those configmaps are written to a folder and accessed by grafana. Changes to the configmaps are monitored and the imported dashboards are deleted/updated. A recommendation is to use one configmap per dashboard, as an reduction of multiple dashboards inside one configmap is currently not properly mirrored in grafana.
Example dashboard config:
```
apiVersion: v1
kind: ConfigMap
metadata:
name: sample-grafana-dashboard
labels:
grafana_dashboard: 1
data:
k8s-dashboard.json: |-
[...]
```
## Sidecar for datasources
If the parameter `sidecar.datasource.enabled` is set, a sidecar container is deployed in the grafana pod. This container watches all config maps in the cluster and filters out the ones with a label as defined in `sidecar.datasources.label`. The files defined in those configmaps are written to a folder and accessed by grafana on startup. Using these yaml files, the data sources in grafana can be modified.
Example datasource config adapted from [Grafana](http://docs.grafana.org/administration/provisioning/#example-datasource-config-file):
```
apiVersion: v1
kind: ConfigMap
metadata:
name: sample-grafana-datasource
labels:
grafana_datasource: 1
data:
datasource.yaml: |-
# config file version
