[openstack-dev] [TripleO] dns for overcloud nodes

2014-08-07 Thread Jan Provaznik

Hi,
by default we don't set nameserver when setting up neutron subnet used 
by overcloud nodes, then nameserver points to the machine where 
undercloud's dnsmasq is running.


I wonder if we should not change *default* devtest setup to allow dns 
resolving not only for local network but for internet? Proper DNS 
resolving is handy e.g. for package update scenario.


This would mean:

a) set explicitly nameserver when configuring neutron subnet (as it's 
done for network in overcloud [1])


or

b) set forwarding dns server for dnsmasq [2]

Any thoughts?

Thanks, Jan

I'd +1 this one

We allow for customization of the OC gateway [1] so it seems reasonable 
to me to just add the config bits for customization of the OC dns servers
