each node has specific value associated rack in cofig.yml. node 1 has setting node.rack: rack1, node 2 setting of node.rack: rack2, , on.

we can create index deploy on nodes have rack set rack1 setting index.routing.allocation.include.tag rack1. example:

curl -xput localhost:9200/test/_settings -d '{ "index.routing.allocation.include.tag" : "rack1" }'
