Hi , I have tried the below .But getting error .Please let me know how I can proceed further . root@cic-1:~# cat try1.yaml heat_template_version: 2013-05-23 description: This is the template for I&V R6.1 base configuration to create neutron resources other than sg and vm for vyos vms parameters: resource_name_map: - network1: NetworkA1 network2: NetworkA2 - network1: NetworkB1 network2: NetworkB2 resources: neutron_Network_1: type: OS::Neutron::Net properties: name: {get_param: [resource_name_map, %index%, network1]} neutron_Network_2: type: OS::Neutron::Net properties: name: {get_param: [resource_name_map, %index%, network2]} root@cic-1:~# cat tryrepeat.yaml heat_template_version: 2013-05-23 resources: rg: type: OS::Heat::ResourceGroup properties: count: 2 resource_def: type: try1.yaml root@cic-1:~# root@cic-1:~# heat stack-create tests -f tryrepeat.yaml WARNING (shell) "heat stack-create" is deprecated, please use "openstack stack create" instead ERROR: resources.rg<nested_stack>: : Error parsing template file:///root/try1.yaml while scanning for the next token found character '%' that cannot start any token in "<unicode string>", line 15, column 45: ... {get_param: [resource_name_map, %index%, network1]} Thanks in advance .

Hi , We are developing heat templates for our vnf deployment .It includes multiple resources .We want to repeat the resource and hence used the api RESOURCE GROUP . Attached are the templates which we used
Set1.yaml -> has the resources we want to repeat Setrepeat.yaml -> has the resource group api with count .
We want to access the variables of resource in set1.yaml while repeating it with count .Eg . port name ,port fixed ip address we want to change in each set . Please let us know how we can have a variable with each repeated resource .
Sounds like you want to use the index_var variable[1] to prefix/suffix reource names? I.e in set1.yaml you can use: name: list_join: - '_' - {get_param: 'OS::stack_name'} - %index% - <resource_name> The example should resulting in something like: stack_0_Network3, stack_0_Subnet3 stack_1_Network0, stack_1_Subnet0 [ ... ] If you want to be more advanced you could use a list parameter in the set1.yaml template, and have each list entry contain a dictionaly of each resource name. The %index% variable would then be used to pick the correct entry from the list. parameters: resource_name_map: - network1: foo_custom_name_net1 network2: foo_custom_name_net2 - network1: bar_custom_name_net1 network2: bar_custom_name_net2 - resources: neutron_Network_1: type: OS::Neutron::Net properties: name: {get_param: [resource_name_map, %index%, network1]} neutron_Network_2: type: OS::Neutron::Net properties: name: {get_param: [resource_name_map, %index%, network2]} %index% is the "count" picking the 'foo' entries when %index% is 0, and 'bar' entries when %index% is 1 and so on.
