<div dir="ltr">Hi Ahmed,<div><br></div><div>ok, thanks - so where does the hostname thats displayed in Horizon come from / is being generated then ? The same domain across all networks is fine at the moment ;) ... we just need to add a "sub-domain" to hosts based on the project name. </div>

<div>Hostnames do not uniquely identify instances, it is the uuid.</div>

<div>As far as I know, If you want to custom define hostname and domain per instance it would be worth looking into cloud-init and user data using APIs, from horizon you can use “Post-Creation” tab during launch instance wizard and provide a customization script.</div>

<div dir="ltr">Hi,
<div><br>
</div>
<div>sorry still not quite what I'm after ... so, when I use the Horizon Dashboard (or the nova api client) I can create a VM that will then get a name allocated based on what I named it, or, what I chose as a prefix if I want to provision 2 or more instances
(uuidgen is used i guess).</div>
<div><br>
</div>
<div>as I will have the same domain + the same IP ranges set for all projects, there will eventually be 2 hosts would get the exact same name, if I were to put something in place that'll automatically update my DNS - how can I change nova/horizon to add a ".$project_name"
to a VM's name, or do I simply change the OS's hostname config and the nova-api & horizon dashboard will pick that up ? </div>

<div><br>
</div>
<div>Yep - I know - but question is, will the OS hostname automatically update the hostname displayed by Horizon when people are using the Dashboard ? Or, if not, how can I convince whatever is creating the VM ( nova-api ? ) to set the hostname as I require
? </div>

You can also pass user-data on Horizon, it's one of the window tabs in the launch instance dialog.

<div>What about the openstack dashboard - will it update the VM's hostname based on the OS's hostname that's set ? </div>

<div dir="ltr">hi all,
<div><br>
</div>
<div>am running openstack in a flat-network with just 1 IP range / network and would like to have the VMs' named after the project, e.g.:</div>
<div><br>
</div>
<div>project name: dev</div>
<div><br>
</div>
<div>host name: redis1</div>
<div>domain: <a href="http://acme.com/" target="_blank">acme.com</a></div>
<div><br>
</div>
<div>resulting name: <a href="http://redis1.dev.acme.com/" target="_blank">redis1.dev.acme.com</a></div>
<div><br>
</div>
<div>at the moment i'd just get a result of <a href="http://redis1.acme.com/" target="_blank">
redis1.acme.com</a> - but do want/need the sub-domains as </div>
<div><br>
</div>
<div>project: dev </div>
<div>and</div>
<div>project: internal</div>
<div>and</div>
<div>project: frontend</div>
<div>etc.</div>
<div><br>
</div>
<div>may use the same name for things they work on ... how is this accomplished ? Or where do I have to look at (in the code) to try and make this a default ? </div>
<div><br>
</div>
<div>Thanks a lot!</div>
