zRPC service discover in mixed cluster deployment scenarios

[dextercai]

I am trying to transfer my serivce from docker (in virtual machine) to K8s clusters. Before it finished, some of services will still keep on the virtual machine. I use the etcd mode for service discover before. Is there any method or technique to make the service exposed using NodePort can be discovered from outof K8s clusters.
Or, in short, is there a way for ZRPC's service discovery function to be used in mixed cluster deployment scenarios (intra cluster, cross cluster)?
