Kubernetes Statefulset

[sigxcpu76]

SummitDB is something I've been looking for for ages: RedisDB-like with JSON and secondary index support. I've successfully set up a cluster on localhost with various ports and tested HA by killing nodes and/or storage, all being successful. The real destination for this is a Kubernetes cluster. I've managed to create a StatefulSet and there were some tricks required:

• listen address should be the POD_IP, not 0.0.0.0 and, of course, not 127.0.0.1.

It clusters beautifully, but there one more issue left. The first node that initiates the clustering is stored in cluster database (Raft?) by IP:port. In a containerized environment IPs are ephemeral, so this will kill the cluster at first node loss.

Now the question is: is it possible to have an "advertise address" parameter that will be used by Raft peering? This way we can have stable Node IDs by using hostnames, which come with a guarantee in a Kubernetes Statefulset.
