I don't know if this is a problem or an issue with our Openstack configuration, but our nova config does not load the 'Attach_interfaces' extension to nova (http://docs.openstack.org/developer/nova/api/nova.api.openstack.compute.contrib.attach_interfaces.html). This in turn means that the OS::Nova::Server.addresses attribute is not available through Heat, which in turn leads Instance.deploy to fail on line 119:
- $.ipAddresses: $outputs.get(format('{0}-assigned-ip', $this.name)).values().flatten().addr.list()
Looking at `heat stack-show`, the associated output lists a 404 Not Found error as its value, and this causes the `values()` call not to be allowed. I don't know how integral this extension is, or if there's a reasonable expectation that it will be there. If that is the case, it seems ok to make that a requirement rather than change behavior. An alternative is to use { get_attr: [servername, networks, { get_attr: [<network>, name] }, 0] } which is what replaced the .firstAddress attribute.
The error I saw in the engine logs was:
