Custom names for resources in cluster created using HEAT templates in Openstack -

i trying create cluster using heat templates of openstack. have following template defining resource group.

cluster:     type: os::heat::resourcegroup     properties:         count: { get_param: instance_count }         resource_def:             type: ../templates/vm.yaml             properties:                 image: { get_param: image }                 flavor: { get_param: flavor }                 private_network : { get_attr : [network, name] } 

this works, name of these servers cryptic. wondering if possible provide prefix name each of instances.

or way can str_replace template value current index of cluster count.

is there way achieve this?

nevermind, got resourcegroup documentation. use %index%.

here example documentation.

resources:   my_indexed_group:     type: os::heat::resourcegroup     properties:       count: 3       resource_def:         type: os::nova::server         properties:           # create unique name each server           # using index in group           name: my_server_%index%           image: centos 6.5           flavor: 4gb performance
