Can I change the hostnames of "node1.domain.tld" to "node1.mydomain.com" without breaking services?

It looks like if I do, ill have to change /etc/hosts on every node. But will I break anything?

If you're using IP on your configurations, then it will not break. You need to edit /etc/openstack-dashboard/local_settings though and modify this line 

 ALLOWED_HOSTS = ['192.168.1.1', '*', 'localhost', ]

You also need to modify your http config in /etc/httpd/conf.d

don't forget to backup the files before editing :)

I don't have a local_settings file in that directory.

I have found a horizon site apache config file under the sites-enabled directory. Im thinking that if I edit that and then edit the /etc/hosts to match my domain, it should work?
