Opensearch Replication Plugin

Hello Opensearch community,

Is there a way to setup opensearch replication across 2 different kubernetes clusters?
Currently, the /_cluster/settings?pretty API accepts the following body:
“persistent”: {
“cluster”: {
“remote”: {
“opensearch-cluster-alias”: {
“seeds”: [“”]

where “seeds” is the elastic discovery service name or IP address.
What I am trying to accomplish is use kubernetes ingress to route traffic to port 9300, but out of the box, kubernetes ingress only supports port 443 and 80 (to my knowledge).

Any suggestions ?
Is replication plugin meant to be implemented across different kubernetes clusters ?

Thank you,
