Open Stack

Hey folks,

Can you confirm if the metadata should work in an ipv6-only environment?

As I understand from this discussion on LP:1460177
<https://bugs.launchpad.net/neutron/+bug/1460177> and the fork of the
discussion in many opendev reviews #315604
<https://review.opendev.org/c/openstack/neutron-specs/+/315604>, #738205
<https://review.opendev.org/c/openstack/neutron-lib/+/738205> #745705
<https://review.opendev.org/c/openstack/neutron/+/745705>, ..., it seems
like it should work.

However, this comment in the openstack doc [1] has me questioning if
it really works.
*"There are no provisions for an IPv6-based metadata service similar to
what is provided for IPv4. In the case of dual-stacked guests though it is
always possible to use the IPv4 metadata service instead. IPv6-only guests
will have to use another method for metadata injection such as using a
configuration drive, which is described in the Nova documentation
on config-drive
<https://docs.openstack.org/nova/latest/user/config-drive.html>."*

Is anyone using metadata in an ipv6-only Openstack setup?

Regards,
Roberto
