We currently allow the management of the alerting cluster in a declarative manner through the
opni.io AlertingCluster CRD
In a near future release, we will support syncing and importing prometheus rules as Alarms through prometheus rule CRDs in dowstream clusters.
Sometime in the future, there are plans to support all AlertManager receivers and and allow imports and syncing of downstream AlertManager CRD resources.
Also note, that in the future there will be group configurations for Alarms, which will handle automatically replicating alarm configurations to clusters based on label matchers or their explicit ids
