Hi David,

the last line in params for server's user_data seems wrong. I really doubt
you literally have template parameter named "OS::Nova::FloatingIP".
Instead you'd have to use get_attr on the OS::Nova::FloatingIP resource you
presumably already created in the template somewhere (you are using it in
the 'association' resource) like that [1]:

$FLOATING_IP: { get_attr: [floating_ip, ip ] }

[1]
http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Nova::FloatingIP-attr-ip

Cheers,
