Validating domain name in FQDN and openstack_domain variable

[Vitaliy Nogin]

In inventory/group_vars/all.yml file and in openstack_hosts/defaults/main.yml role openstack_domain variable defined as openstack.local

openstack_domain: openstack.local

However, during OSA deployment by some reason, we use FQDN name.

In /etc/hosts file all hosts populated with openstack.local domain name:

root@728987-comp-disk-238:/etc/ansible# cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 728987-comp-disk-238.local.lan 728987-comp-disk-238

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.20.112.63 729359-comp-disk-335.openstack.local 729359-comp-disk-335
172.20.112.51 729075-comp-disk-290.openstack.local 729075-comp-disk-290

172.20.112.155 728987-comp-disk-238-rsyslog-container-2fba7186.openstack.local 728987-comp-disk-238-rsyslog-container-2fba7186 728987-comp-disk-238_rsyslog_container-2fba7186
172.20.112.55 728987-comp-disk-238.openstack.local 728987-comp-disk-238

Nevertheless, nova uses FQDN domain:

root@729013-comp-disk-259-utility-container-c71251fe:~# nova hypervisor-list
+-----+--------------------------------+-------+---------+
| ID | Hypervisor hostname | State | Status |
+-----+--------------------------------+-------+---------+
| 2 | 729075-comp-disk-290.local.lan | up | enabled |
| 5 | 729359-comp-disk-335.local.lan | up | enabled |
---------------- skipped by vnogin ---------------------
| 155 | 729675-comp-disk-217.local.lan | up | enabled |
| 158 | 729002-comp-disk-223.local.lan | up | enabled |
+-----+--------------------------------+-------+---------+

After deployment, we don't have compute nodes with proper functionality and due to this fact we not able to perform live migration (for instance).

From my point of view, we need to have validation for a domain name in FQDN and openstack_domain variable for avoiding such problems after deployment.

Closing this bug due to age, and openstack-ansible not being opionated about how operators setup their hosts/domains in DNS or otherwise.
