Druid cluster on GKE

I am trying to deploy Druid cluster on GKE env. I am trying to create Master pods and query pods. Data is on VMs. there is property called druid.host which I have to set in run time files. What should be its value ?. I have made it as localhost and trying to connect query pod with load balance ip but I am getting error.

Any help will be appreciated.

The host for the current node. This is used to advertise the current processes location as reachable from another node and should generally be specified such that http://${druid.host}/ could actually talk to this process. So Localhost won’t work, try IP or Hostname

Please scrap Druid docs for more info!
