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 Reviewed-on: #509 Co-authored-by: unkin-agent <unkin-agent@unkin.net> Co-committed-by: unkin-agent <unkin-agent@unkin.net>
