Why not use Owns(&v1.ConfigMap{}) instead? That would trigger the normal reconcile function where we could check if it's the right configmap.

Unfortunately, the owner of the configmap is not a DataSource resource, but a Grafana resource.
So we cannot use Owns(&v1.ConfigMap{}) in this controller.

Description
If a datasource resource is created before grafana-controller creates a configmap resource, the datasource resource will not be imported.
I fixed it so that datasource-controller triggers configmap changes to reconcile datasources.
