Grafana allows you manage alerting rules for an external Cortex or Loki instance.
In order for both Cortex and Loki data sources to work with Grafana 8.0 alerting, enable the ruler API by configuring their respective services. The`local` rule storage type, default for Loki, only supports viewing of rules. If you want to edit rules, then configure one of the other rule storage types. When configuring a Grafana Prometheus data source to point to Cortex, use the legacy `/api/prom` prefix, not `/prometheus`. Only single-binary mode is currently supported, and it is not possible to provide a separate URL for the ruler API.
