Continental Innovates with Rancher and Kubernetes
To allow the Grafana dashboard to persist after the Grafana instance restarts, add the dashboard configuration JSON into a ConfigMap. ConfigMaps also allow the dashboards to be deployed with a GitOps or CD based approach. This allows the dashboard to be put under version control.
The monitoring application needs to be installed.
You must have the cluster-admin ClusterRole permission.
Create a ConfigMap in the cattle-dashboards namespace. The ConfigMap needs to have the label grafana_dashboard: "1". Paste the JSON into the ConfigMap in the format shown in the example below:
Result: After the ConfigMap is created, it should show up on the Grafana UI and be persisted even if the Grafana pod is restarted.
Dashboards that are persisted using ConfigMaps cannot be deleted from the Grafana UI. If you attempt to delete the dashboard in the Grafana UI, you will see the error message “Dashboard cannot be deleted because it was provisioned.” To delete the dashboard, you will need to delete the ConfigMap.
