[Tuna]

  Hello,

  I installed tacker on my controller node manually. I succeeded to start it, deploy a vnfd which were a sample on Tacker's Manual Installation page. (OpenWRT)

  When i try to create vnf, it stucks in ERROR status :

(tacker.log ERROR)
ERROR tacker.vnfm.plugin [-] VNF Create failed for vnf_id 47be08ca-b1ae-417b-9165-07cdf5ad12db

It's running on Newton.

Control your /etc/heat/policy.json file. Tacker's manual installation guide is a little confusing, problem is about "resource_types:OS::Nova::Flavor": "rule:project_admin" line. Don't change that line, neccessary roles are configured as default so you don't need to change anything. This solved my issue. (I had been changed the rule to role or made some other configuration, so that was the problem.)

[Ashish (ashish235)]

I didn't change that line in policy.json and I was aware of that configuration. This is the 5-6th time I 've installed tacker and I 'm facing this issue for 1st time.

I still have "resource_types:OS::Nova::Flavor": "rule:project_admin",

Hi Team,

This bug is a major blocker for me. I was working on tacker for a project which was supposed to be production ready in 2 weeks and now I 'm helpless.

Can anyone help with the fix or a workaround for this problem? Because it now seems that tacker can't be used at all.

I 've Tacker installed in two different setups and I 've tried from both the setups to control one VIM which I 've and facing the same issue in both the cases.

If someone needs any debug/additional info do let me know.

Thanks.

I had the same issue and added the 'user_data_format: RAW' line to resolve it:

topology_template:
  node_templates:
    VDU1:
      type: tosca.nodes.nfv.VDU.Tacker
      properties:
        user_data_format: RAW
        ...
