[2.3.0] metadat URL is [::1] when no port is specified for ipv4 IP in rackd.conf

[Jeff Hillman]

MAAS 2.3.0
Xenial 16.04.3

When adding a rack controller to an existing region controlelr either via 'maas-rack register' and specifying http://a.b.c.d/MASS OR just editing /etc/maas/rackd.conf and setting the URL to http;//a.b.c.d/MASS, causes the metadata URL provided during commssioning to be http://[::1]:5240/MAAS.

To resolved this, either register with http://a.b.c.d:5240/MAAS or edit the URL in /etc/maas/rackd.conf to be http://a.b.c.d:5240/MAAS.

Basically, if you do not specify a port with an IPv4 address to the rack controller, then it will assume IPv6 with the 5240 port to provide a metadata URL.

Thanks for the bug.

The one thing we need to verify is whether this is also present in 2.3.1, as Mike believes it should have been fixed then.

However, we have seen this issue when rackd.conf was pointing to localhost.

[Andres Rodriguez (andreserl)]

In this case:

cloud-config-url=http://[::1]:5240/MAAS/metadata/....

We believe this issue has now been fixed in the latest MAAS release, as part of the proxying through the rack feature.

If you believe this issue is still present in 2.3 and/or is affecting users, please re-open the 2.3 bug task. (I'll mark it as wontfix)
