Im wanting to grow my elasticsearch installation into a cluster. To this end I'd like to run it under kubernetes but I can't figure out how to keep the various data stores (per container) properly assigned.
IE if I were using dedicated hosts Id have local storage and each cluster member would use that storage. If I move to k8 I need to have a system that cluster members can come / go and know which data to associate with. Does that make any sense? Im sure this has been figured out / understood but I can't think of the proper question(s) to ask.
Reading about clustering (here) I get the sense that SANs aren't the way to go. Latency is low but local disks seem to be preferred. Accurate?
Any pointers would be appreciated.
