Use cases like single-node deployments (e.g. far-edge) don't need to deploy a local Alertmanager cluster because alerts are centralized at the core (e.g. hub cluster), running Alertmanager locally takes resources from user workloads and adds management overhead. Cluster admins should be able to not deploy Alertmanager as a day-2 operation.

DoD

• Alertmanager isn't deployed when switched off in the CMO configmap.
• The OCP console handles the situation gracefully when Alertmanager isn't installed informing users that it can't manage the local Alertmanager configuration and resources.

  • Alertmanager config editor
