[1.5] Have several independant "node"


I must deploy several elastic instance in the same server (inside docker container for each) but I don't want they see each other like a replica node.
I need they are like independant "database", don't communicate each other.

How can i do that ?

Thx for your response.

In 1.x, I'd set:

discovery.zen.ping.multicast.enabled: false

if i set my setting index number_of_replicas to 0, it resolve this issue ?

No. If at some point they form a cluster you will never know on which node your shard will be allocated.
