Hi folks!

I'm looking into support for multiple overclouds with shared control plane.
I'm porting a downstream guide: https://review.openstack.org/368840.

However, this no longer works, probably because "internal_api" network name
is hardcoded in ServiceNetMapDefaults: 
https://github.com/openstack/tripleo-heat-templates/blob/dfe74b211267cde7a1da4e1fe9430127eda234c6/network/service_net_map.yaml#L14.
So deployment fails with

CREATE_FAILED resources.RedisVirtualIP: Property error:
resources.VipPort.properties.network: Error validating value 'internal_api':
Unable to find network with name or id 'internal_api'

Is it a bug? Or is there another way to change the network name? I need it
to avoid overlap between networks from two overclouds. I'd prefer to avoid
overriding everything from ServiceNetMapDefaults in my network environment
file.

IMO this isn't a bug, but an RFE perhaps.

RFE filed: https://blueprints.launchpad.net/tripleo/+spec/override-network-name


The reason is that until a couple of weeks ago, you always had to fully
define all services in ServiceNetMap, so this is basically just a case
where the optimization introduced here (which allows you to partially
specify ServiceNetMap which is then merged with ServiceNetMapDefaults)
doesn't work:

https://review.openstack.org/#/c/353032/

I'd say overriding everything is an OK workaround, but we can definitely
discuss ways to do it more cleanly - I'll give it some thought (probably
we'll need another mapping that defines the network names that can be
easily overidden).

Overriding everything does allow me to move forward, thanks.
