Hello,

Template used: https://github.com/openstack/tacker/blob/master/samples/tosca-templates/vnfd/tosca-vnfd-alarm-scale.yaml

Tacker version: 0.7.1

I am using above mentioned template and getting following error in tacker.log:

It looks resize_compute is missing in template.
Could you please try with https://github.com/openstack/tacker/blob/stable/newton/samples/tosca-templates/vnfd/tosca-vnfd-alarm-scale.yaml

[Amit Bhardwaj (bhardwajamit23)]

Hello Dharmendra,

I used the template that you have shared. It works if I keep my VM instance name as VDU1 only.

    VDU1:
      type: tosca.nodes.nfv.VDU.Tacker
      properties:
        image: {get_input: image}
        flavor: {get_input: flavor}
        availability_zone: {get_input: zone}
        name: amitbhardwaj_mtcgw_repo_dns_1
        mgmt_driver: noop

If for example I use something else in place of VDU1, it fails with following exception:

Hello Again,

Link 438 of /usr/local/lib/python2.7/dist-packages/tacker/vnfm/infra_drivers/openstack/openstack.py
has a hardcoded reference of VDU1

                if 'policies' in topology_tpl_dict:
                    for policies in topology_tpl_dict['policies']:
                        policy_name, policy_dt = list(policies.items())[0]
                        if policy_dt['type'] == \
                                'tosca.policy.tacker.Scaling':
                            # Fixed metadata. it will be fixed
                            # once targets are supported
                            metadata_dict = dict()
                            metadata_dict['metering.vnf_id'] = vnf['id']
                            sub_heat_dict['resources']['VDU1']['properties']['metadata'] =\
                                metadata_dict
                            matching_metadata_dict = dict()
                            matching_metadata_dict['metadata.user_metadata.vnf_id'] =\
                                vnf['id']
                            mon_policy_hot['properties']['matching_metadata'] =\
                                matching_metadata_dict

Can you please check?

Also, I tried with VDU1 as hard-coded name for VM and I am getting error:

Is anyone working on this?

[dharmendra (dharmendra-kushwaha)]

Hi Amit,

I suspect, Tacker version(0.7.1) mentioned in description seems incorrect.

Points you mentioned in comment #3 already fixed.

could you please verify it again, and please share the execution steps & your vnfd file.

It will be better to test on Ocata/stable or latest master.
