Keycloak with external multiple Infinispan replicas

I run Keycloak v17 (Quarkus) and remote Infinispan on Kubernetes. It runs fine with single Keycloak pod and single Infinispan pod. However, it does not run with single Keycloak pod and multiple Infinispan pods.

When I run single Keycloak pod and single Infinispan pod I provide remote-server host to be Infinispan Kubernetes service name (fx infinispan.keycloak.svc.cluster.local). However during the Keycloak start I see that the host is changed from Kubernetes service ip to a pod ip:

2022-03-23 12:21:47,801 INFO  [org.infinispan.HOTROD] (blocking-thread--p3-t1) ISPN004021: Infinispan version: Infinispan 'Triskaidekaphobia' 13.0.5.Final

However, when I change it to two Infinispan replicas, it looks like the Keycloak only “remembers” one Infinispan pod ip, but not the other:

So how do I use Keycloak with external multiple replicas Infinispan?
