我再两套k8s集群里容器化部署了两套doris集群，我想让他们之间定期数据同步应该怎么做

使用ccr会报错，doris会返回fqdn域名
{"success":false,"error_msg":"get url: http://doriscluster-helm-be-0.doriscluster-helm-be-internal.default.svc.cluster.local:8040/api/show_config?conf_item=enable_feature_binlog failed: [normal] Get "http://doriscluster-helm-be-0.doriscluster-helm-be-internal.default.svc.cluster.local:8040/api/show_config?conf_item=enable_feature_binlog": dial tcp: lookup doriscluster-helm-be-0.doriscluster-helm-be-internal.default.svc.cluster.local: Temporary failure in name resolution"}
