Hi,
Could anyone shed some light on how to get the physical interface name
(e.g eth0) from network name (e.g PublicNetwork, ExternalNetwork) in
tripleo-heat-template service profile ?
for example:
I want to add a service profile under puppet/services/time/ptp.pp where
it uses 'PtpInterface' as a parameter to get physical interface name
(please refer to below piece of code), but I'd like to expose a more
user friendly parameter like NetworkName(e.g. provision network,
external network etc) instead of 'PtpInterface' and retrieve the actual
physical interface name from the NetworkName where the physical
interface is connected to, is there any possible way to do this ?
I don't think there is. In many cases the templates don't even know the
name of the physical device on which the network will be running. A
simple example would be when a user uses the nicX abstraction to specify
interfaces in their net-iso templates. That doesn't get mapped to an
actual interface name until os-net-config runs, and the results of that
run are not available to the templates.

- map_replace:
- tripleo::profile::base::time::ptp::ptp4l_interface:
PtpInterface
- values: {get_param: [RoleParameters]}
- values:
PtpInterface: {get_param: PtpInterface}
outputs:
role_data:
description: Role ptp using commposable services.
value:
service_name: ptp
config_settings:
map_merge:
- get_attr: [RoleParametersValue, value]
[...]

Thanks!
