Dear Openstack community,
I am testing a big data cluster application that needs DNS service across the cluster (at the moment the cluster is running on vms for testing) so I decided to give designate a go.
Because my deployment is based on kolla-ansible so I decided to follow this document http://egonzalez.org/deploy-openstack-designate-with-kolla-ansible/ which has helped me a lot to get designate up and running.
The installation was successful and I could create a DNS zone and assign it to my private network.
The problem I am having is that the instance domain changes from what I have in designate (garvan.openstack.org.) to nova (novalocal) when the instance reboots.
I create a new vm and the FQDN (hostname -f) is myvm.garvan.orpenstack.org but after reboot it changes to myvn.novalocal.
This is what I can see from journal
[centos@myvm ~]$ journalctl | grep novalocal
Jun 01 11:52:13 myvm cloud-init: [CLOUDINIT] ccsethostname.py[DEBUG]: Setting the hostname to myvm.novalocal (myvm)
My questions is, why is this happening and why is cloud-init or nova not following the setup from designate? Is this an issue with nova, neutron or designate and how can I fix it?
I am running ocata and my environment is quite standard so I assume this issue may be affecting many people.
Thank you very much
