Open Stack

Try to look into changing dhcp_domain in nova.conf to make it work, but will be for all instances.

dhcp_domain = <domain>
Note: <domain> is the domain name to use for building the hostnames

Or look into cloud-init to customize FQDN per instance, see http://docs.openstack.org/user-guide/content/user-data.html

Hope this is what you are looking for.

Subject: Re: [Openstack-operators] how can I make a new VM use the project name as sub-domain ?

Hi Abel,

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 ?

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

Thanks!

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

hi all,

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.:

project name: dev

host name: redis1
domain: acme.com<http://acme.com/>

resulting name: redis1.dev.acme.com<http://redis1.dev.acme.com/>

at the moment i'd just get a result of redis1.acme.com<http://redis1.acme.com/> - but do want/need the sub-domains as

project: dev
and
project: internal
and
project: frontend
etc.

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 ?

Thanks a lot!
Alex
