What version have you set for your stack?

Part of my stack looks like:

----- s n i p -----
heat_template_version: 2016-04-08
description: Instance template
[..]
resources:
[..]
  port:
    type: OS::Neutron::Port
    properties:
      name: { get_param: name }
      network: { get_param: network }
      security_groups: { get_param: secgrps }
----- s n i p -----

And that works just fine - no need for fixed_ips.

Hint: Use list_join instead..


Oh, and just to 'blow your mind', this is one of my absolute
"worst" :)

I use it for creating a DNS record for the instance in Designate,
because a auto scaling group doesn't have a "counter" ('%index%')
like a resource group have..
