Tacker scale does not work

Asked by futangw

Hi,

I've created a very simple scale vnfd, but it failed to scale out/in. The VNF state changed from active->pending scale out -> active, but no more instance was created. do i miss anything?

Here's the VNFD:

tosca_definitions_version: tosca_simple_profile_for_nfv_1_0_0

description: sample-tosca-vnfd-scaling

topology_template:
  node_templates:
    VDU1:

          max_instances: 8
          default_instances: 2
          targets: VDU1

With this VNFD i can deploy VNF successfully where 2 instance have been created.

But when i run scale, it does not work.
tacker vnf-scale --vnf-name vnfd-scale-vnf --scaling-policy-name SP1 --scaling-type out

Looks there's some problem on heat:

For other reference in case someone encounters this again.
The heat error is due to no permission of operating OS::Nova::Flavor. The role used for scale is heat_stack_owner, so by adding
"resource_types:OS::Nova::Flavor": "role:heat_stack_owner" in the heat policy file, the error was gone.

Then in case see another error: Policy doesn't allow os_compute_api: os-flavor-manage to be performed. (HTTP 403), it's an permission error in nova-api, add or update to "os_compute_api:os-flavor-manage": "" in nova policy file.

just fyi
