[Rdo-list] define service endpoints

[Zhao, Xin]

Hello,

When one defines services endpoints in keystone, eg. for neutron, the 
publicurl should be using the outfacing NIC IP (or external hostname of 
the controller), while the internalurl and adminurl should be using the 
internal management subnet NIC IP (or the internal hostname of the 
controller). Do I understand this right? My controller has an out-facing 
IP/hostname and an internal hostname/IP on the management subnet.

Thanks,
Xin
