When attempting to add a DruidIngestion resource on a k8s cluster which has a clusterDomain set to anything other than cluster.local, it will fail due to cluster.local being hard-coded in the GetRouterSvcUrl fuction in druidapi.go.

Error from operator logs when I try to apply a DruidIngestion resource:

2025-03-05T04:17:52Z    ERROR   Post "http://REDACTED-routers.REDACTED.svc.cluster.local:8088/druid/indexer/v1/supervisor": dial tcp: lookup REDACTED-routers.druid-REDACTED.svc.cluster.local on 10.96.0.10:53: no such host   {"controller": "druidingestion", "controllerGroup": "druid.apache.org", "controllerKind": "DruidIngestion", "DruidIngestion": {"name":"REDACTED","namespace":"druid-REDACTED"}, "namespace": "druid-REDACTED", "name": "REDACTED", "reconcileID": "c746475a-36b3-49c9-b018-4ef7166e9c22", "error": "Post \"http://REDACTED.svc.cluster.local:8088/druid/indexer/v1/supervisor\": dial tcp: lookup REDACTED-routers.REDACTED.svc.cluster.local on 10.96.0.10:53: no such host"}

Code at fault:

druid-operator/pkg/druidapi/druidapi.go

Line 132 in 2087f15

newName := "http://" + svcName + "." + namespace + ".svc.cluster.local:" + DruidRouterPort
