Ah, sorry. I misunderstood what you were trying to do. Why create a template that takes in a list of pool members, rather then pass the pool id to the template the instance is in, and use a PoolMember to attach it?

Hi We are in fact using OS::Neutron::PoolMember resource. I guess ResourceGroup is the only iterative construct in Heat. Is the use case supported today? I think this is more than a simple usage question, hence posting it here. Thank you.

I am trying to find a way of creating a dynamic List of Resources(Loadbalancer PoolMembers to be exact) using Heat. The idea is that the number of PoolMembers and the required Addresses would be received as Heat parameters. However, I am unable to get %index% working inside a Fn:Select block. Is this a bug with Heat or am I doing something wrong ? If this is a bug/limitation in heat is there some other way to get what I am trying to do working with heat ? IMO this is a very important usecase for the %index%.
