Grafana runs 3 replicas with no alerting HA config, so every replica sends every notification.

  • add headless grafana-alerting Service exposing gossip on 9094 TCP/UDP
  • inject POD_IP from status.podIP into the grafana container
  • set unified_alerting ha_peers, ha_listen_address and ha_advertise_address so replicas form one Alertmanager cluster
Grafana runs 3 replicas with no alerting HA config, so every replica sends every notification. - add headless `grafana-alerting` Service exposing gossip on 9094 TCP/UDP - inject `POD_IP` from `status.podIP` into the grafana container - set `unified_alerting` `ha_peers`, `ha_listen_address` and `ha_advertise_address` so replicas form one Alertmanager cluster
