Re: [keycloak-user] kubernetes discovery protocol for JGroups

Meissa, I believe the difference is in how it gets the data about the instances in the cluster. DNS_PING obviously will use DNS, in a Kubernetes env you will want to setup a headless service for that so it gets all the IPs for all the instances. As for KUBE_PING, well that uses the Kubernetes API directly to determine the IPs of the instances. I run vanilla Kubernetes clusters so I don't know how the difference with OS will effect my beliefs. However, I would probably recommend just using DNS_PING and making sure that there is a headless service as well as a normal service for Keycloak. It would seem to be the more generic method for sure.

It seems like both of them could be used in a kubernetes environment but I can't see a documentation clearly explaining the difference between them. I would like to knwo which one is relevant in a openshift environnement which one is in a non openshift environnement. The official githup repo [1] does not say a lot about that?
