Error in sink formatv4 neutron_floatingip handler

[Eran]

Working with OpenStack kolla, designet fails with formats types.

[handler:neutron_floatingip]
zone_id = "f6150699-b84c-4891-bcfc-79f9e4e308f2"
formatv4 = '%(octet0)s-%(octet1)s-%(octet2)s-%(octet3)s.%(zone)s'
formatv4 = %(hostname)s.prv.%(zone)s
formatv4 = '%(hostname)s.%(project)s.prv.%(zone)s'
formatv6 = %(hostname)s.prv.%(zone)s
formatv6 = '%(hostname)s.%(project)s.prv.%(zone)s'

in the DNS it only register the formatv4 = '%(octet0)s-%(octet1)s-%(octet2)s-%(octet3)s.%(zone)s' failing with the others.

[Erik Olof Gunnar Andersson (eandersson)]

This is unfortunately a bug with Kolla. The problem is that the Neutron payload does not contain hostname, and cannot be used as a parameter.

For that reason Kolla removed those suggestions with this patch.
https://github.com/openstack/kolla-ansible/commit/5ae4b7c02957a067ea3b757a2ea389e548153936#diff-182e3de6ae03bcb6096c97287901258d

You can see an example of a payload sent by Neutron here.
