getting VNF details for Tacker VM

Hi Kali,

There is Tacker API to get VNF details.

From the command line, you can use python-tackerclient to show VNF information using the below command

tacker vnf-show <vim name or id>

Currently, we do no support accessing the VNF information from Horizon. Bu that will be a good RFE to implement within Tacker.

Sripriya,

 Thanks for your prompt response.

But when I run the vnf-show command it is not giving the details. It just gives the details of the VM while captured during the VM creation.

Pls see my screenshots below.

Also I have a question. If you see the output of vnf-create, you will see, instance id. But when I go to instance details screen in openstack. that id is completely different. So I am not able to link with instance from any of the vnf_create outputs except tenenat_id. It would be great help if you provide some inputs on this.

Hi,

The instance_id in vnf-show command refers to heat stack_id and not the actual VM itself. I understand the nomenclature used here is confusing. If you fetch the resources for the given stack_id, you will be able to see the actual instance id of the VM. Right now from Tacker, you do not have the option to see the VM instance id. However, you should be able to see the Instance IP address in the mgmt_url column, I see mgmt_url empty in your screenshot. Can you confirm if spinning a normal openwrt VM as a nova instance in the tenant is acquiring IP successfully?

I'll create a RFE to update instance_id as stack_id to avoid the confusion.

Hi Sripriya,

Thanks again for your prompt response.

Here is what I do. I installed the latest master branch with tacker as explained the installation steps. Once installed, then I go openstack UI by logging in admin/devstack and it brings me to the demo project.
Then I use the NFV tab in UI to onboard the vnfd using the openWRT image and onboard the VNF using the vnfd in the same NFV UI. Even for this, when I do the vnf-show, it is not giving the ip details. Also I tried to look at the vnfd id in tacker.log and use that vnfid to create the VM via vnf-create command. Then I did vnf-show with id generated in vnf-create command. But if I go to instance details screen in admin project, then it brings the instance with all details but vnf-show is not showing the details.

you were mentioning above getting the entire details using instance_id as stack_id. what command used for this and how do get the details.

If would be great help if you let me know the ways to get the instance details. or how do I verify this?.

thanks
kali

In the sample output in #2 above the VNF is in PENDING-CREATE state and mgmt-url field is empty. Can you wait until VNF goes to ACTIVE state and then do a 'vnf-show' ? mgmt-url should display a dictionary of ip addresses.

+1 to link this to a bug to change "instance_id" -> "stack_id"
