For add_gateway_to_router():

So I tried this:
external_network = conn.network.find_network(EXTERNAL_NETWORK_NAME)
network_dict_body = {'network_id' : external_network.id}
conn.network.add_gateway_to_router(onap_router, **network_dict_body)

==> no errors, but the router is not updated (no gateway is set)
(external_gateway_info is still None)

(same with conn.network.add_gateway_to_router(onap_router, network_id=external_network.id) )

Is the body parameter for add_gateway_to_router() expected to correspond to a Network ?
(from a router point of view, a "gateway" is an external network)

Should the network's subnet(s) be also specified in the dictionary ? Maybe only
if certain specific subnets are desired for the gateway role. Otherwise,
the default would apply: there is usually only 1 subnet, and that's the one
to be used. So network_id would be enough to specify a gateway used in a standard way.

Maybe more details about what is expected in this body dictionary should be documented
in the add_gateway_to_router() section?

In Horizon, when selecting a router, and selecting "Set Gateway", the user is only
asked to pick an external network from a dropdown list. Then, a router interface is
implicitly created, with an IP@ picked from the subnet of that network.

For router deletion: it looks like it's the "!= None" test on the returned object that has an issue

        onap_router  = conn.network.find_router(ONAP_ROUTER_NAME)
        if onap_router != None:
            print('Deleting ONAP router...')
            conn.network.delete_router(onap_router.id)
        else:
            print('No ONAP router found...')

I added traceback printouts in the code.

printing the router before trying to delete it:
 onap_router:
 openstack.network.v2.router.Router(updated_at=2018-05-04T21:07:23Z, description=Router created for ONAP, status=ACTIVE, ha=False, name=ONAP_router, created_at=2018-05-04T21:07:20Z, tenant_id=03aa47d3bcfd48199e0470b1c86a7f5b, availability_zone_hints=[], admin_state_up=True, availability_zones=['nova'], tags=[], revision=3, routes=[], id=675abd14-096a-4b28-b764-31ca7098913b, external_gateway_info=None, distributed=False, flavor_id=None)

--------------------------------------------------------------------
For identity_api_version=3 :

yes, that worked !

Could that identity_api_version parameter also/instead be specified in the clouds.yaml file ?


--------------------------------------------------------------------
Here's the traceback info for the flavor error, also on the "!= None" test :

*** Exception: <class 'AttributeError'> 'NoneType' object has no attribute '_body'
*** traceback.print_tb():
  File "auto_script_config_openstack_for_onap.py", line 537, in configure_all_ONAP

    return all([self._body.attributes == comparand._body.attributes,

--------------------------------------------------------------------
For the image creation:

ah, OK, indeed, there is an image proxy (even 2: v1, v2),
and maybe the compute / image operations are redundant (or maybe not, for convenience) ?

and yes, it worked ! There was no need for additional parameters.
