your log: Not found address of host: clickhouse-keeper-0.clickhouse-keeper-headless.clickhouse.svc.cluster.local. (DNS_ERROR),

your config: namespaceDomainPattern: "%s.svc.cluster.test"

I'm not one of the clickhouse or altinity developers but it seems you should use: namespaceDomainPattern: "%s.svc"

@ahmadubuntu

spec:
  namespaceDomainPattern: "%s.svc"
