Keycloak Quarkus ISPN Bind Address


Keycloak tries to discover cluster nodes on the wrong ethernet interface:

01 15:09:24 orpheus[9464]: 2022-05-01 15:09:24,894 INFO [org.infinispan.CLUSTER] (keycloak-cache-init) ISPN000079: Channel ISPN local address is orpheus-29191, physical addresses are []

How do I define which address or interface to bind to? I’m trying to use the default UDP/Multicast based node discovery mechanism.
