ETSI NFV-SOL VNF Deployment as VM with LCM Operation User Data¶
This document describes how to deploy VNF as VM with LCM operation user data in Tacker v2 API using CLI commands. Please check LCM-user-data spec and NFV-SOL014 v2.8.1 for more information on LCM operation user data.
Note
The content of this document has been confirmed to work using the following VNF Package.
Overview¶
The diagram below shows an overview of the VNF deployment.
Request create VNF
A user requests tacker-server to create a VNF with tacker-client by uploading a VNF Package and requesting
create VNF. The VNF Package should containBaseHOTandUserDatain addition toVNFD. The detailed explanation of these contents can be found in VNF Package.Request instantiate VNF
A user requests tacker-server to instantiate the created VNF by requesting
instantiate VNFwith instantiate parameters.Call OpenStack Heat API
Upon receiving a request, tacker-server redirects it to tacker-conductor. In tacker-conductor, the request is redirected again to an appropriate infra-driver (in this case OpenStack infra-driver) according to the contents of the instantiate parameters. Then, OpenStack infra-driver calls OpenStack Heat APIs to create a VM as a VNF.
Create a VM
OpenStack Heat creates a VM according to the API calls.
Prerequisites¶
The following packages should be installed:
tacker
python-tackerclient
A default VIM should be registered according to VIM Management.
As an example, you can register default VIM as follow.
$ cat vim_config.yaml
auth_url: 'http://192.168.56.10/identity'
username: 'nfv_user'
password: 'devstack'
project_name: 'nfv'
project_domain_name: 'Default'
user_domain_name: 'Default'
cert_verify: 'False'
$ openstack vim register --config-file vim_config.yaml \
--is-default openstack-admin-vim

The VNF Package(sample_csar.zip) used below is prepared by referring to VNF Package.
Note
In order to deploy VNF using LCM operation user data, it is necessary to include BaseHOT and UserData in the VNF Package, which are optional in VNF Package.
As an example, you can create a VNF Package as follow.
In this document, TACKER_ROOT is the root of tacker’s repository on
the server.
$ cd TACKER_ROOT/samples/tests/functional/sol_v2_common/basic_lcms_max_individual_vnfc

Note
This tool requires some Tacker modules, so you need to run it in an environment where Tacker is installed. If you have installed Tacker in python virtual environment using devstack, etc., please activate it as follows before using the tool.
$ source /opt/stack/data/venv/bin/activate
(venv) $ python3 pkggen.py
After you have done the above, you will have the sample VNF package basic_lcms_max_individual_vnfc.zip.
Note
If a file exists with the same name as the zip file being generated, the tool will fail. When running the tool again to generate a zip file, please delete or rename the old zip file.
VNF Deployment Procedure as VM¶
In order to deploy VNF as a VM, it is necessary to execute the following procedure. Details of CLI commands are described in VNF Package Management and VNF Lifecycle Management with v2 Tacker.
1. Create VNF Package Info¶
Execute the following CLI command to create VNF Package.
$ openstack vnf package create

| | } |
| | } |
| Onboarding State | CREATED |
| Operational State | DISABLED |
| Usage State | NOT_IN_USE |
| User Defined Data | {} |
+-------------------+-------------------------------------------------------------------------------------------------+
After that, execute the following CLI command and confirm that VNF Package creation was successful.
Confirm that the ‘Onboarding State’ is ‘CREATED’.
Confirm that the ‘Operational State’ is ‘DISABLED’.
Confirm that the ‘Usage State’ is ‘NOT_IN_USE’.
$ openstack vnf package show VNF_PACKAGE_ID \
-c 'Onboarding State' -c 'Operational State' -c 'Usage State'
Result:
+-------------------+------------+
| Field | Value |
+-------------------+------------+
| Onboarding State | CREATED |
| Operational State | DISABLED |
| Usage State | NOT_IN_USE |
+-------------------+------------+
2. Upload VNF Package¶
Execute the following CLI command to upload VNF Package.
$ openstack vnf package upload --path sample_csar.zip VNF_PACKAGE_ID
Result:
Upload request for VNF package aeb0f04a-06a5-40d5-b5dd-73720a886da4 has been accepted.
After that, execute the following CLI command and confirm that VNF Package uploading was successful.
Confirm that the ‘Onboarding State’ is ‘ONBOARDED’.
Confirm that the ‘Operational State’ is ‘ENABLED’.
Confirm that the ‘Usage State’ is ‘NOT_IN_USE’.
Take a note of the ‘VNFD ID’ because you will need it in the next ‘Create VNF Identifier’.
Note
The state of ‘Onboarding State’ changes in the order of ‘UPLOADING’, ‘PROCESSING’, ‘ONBOARDED’.
$ openstack vnf package show VNF_PACKAGE_ID \
-c 'Onboarding State' -c 'Operational State' -c 'Usage State' -c 'VNFD ID'
Result:
+-------------------+--------------------------------------+
| Field | Value |
+-------------------+--------------------------------------+
| Onboarding State | ONBOARDED |
| Operational State | ENABLED |
| Usage State | NOT_IN_USE |
| VNFD ID | 005b0c0a-45a7-45b7-85b7-f7457227f241 |
+-------------------+--------------------------------------+
3. Create VNF Identifier¶
Execute the following CLI command to create a VNF instance.
$ openstack vnflcm create VNFD_ID --os-tacker-api-version 2
Result:
+-----------------------------+------------------------------------------------------------------------------------------------------------------+
| Field | Value |
+-----------------------------+------------------------------------------------------------------------------------------------------------------+

| | }, |
| | "instantiate": { |
| | "href": "http://127.0.0.1:9890/vnflcm/v2/vnf_instances/394575b8-50ae-43a2-9aa6-a7691ea10794/instantiate" |
| | } |
| | } |

| VNFD Version | 1.0 |
+-----------------------------+------------------------------------------------------------------------------------------------------------------+
After that, execute the following CLI command and confirm that VNF instance creation was successful.
Confirm that the ‘Usage State’ of the VNF Package is ‘IN_USE’.
Confirm that the ‘Instantiation State’ of the VNF instance is ‘NOT_INSTANTIATED’.
$ openstack vnf package show VNF_PACKAGE_ID -c 'Usage State'

4. Instantiate VNF¶
Create a sample_param_file.json file with the following format. This is the file that defines the parameters for an instantiate request. These parameters will be set in the body of the instantiate request.
Required parameter:
flavourId
additionalParams
Note
Details of flavourId is described in VNF Descriptor (VNFD) based on ETSI NFV-SOL001.
Note
additionalParams is a parameter that can be described by KeyValuePairs. By setting the following two parameters in this parameter, instantiate using LCM operation user data becomes possible. For file_name.py and class_name, set the file name and class name described in Prerequisites.
lcm-operation-user-data: ./UserData/file_name.py
lcm-operation-user-data-class: class_name
Optional parameters:
instantiationLevelId
extVirtualLinks
extManagedVirtualLinks
vimConnectionInfo
localizationLanguage
extensions
vnfConfigurableProperties
Note
You can skip vimConnectionInfo only when you have
the default VIM described in VIM Management.
Note
This operation can specify the vimConnectionInfo
for the VNF instance.
Even if this operation specify multiple vimConnectionInfo
associated with one VNF instance, only one of them will be used for
life cycle management operations.
Param file with only required parameters:

"additionalParams": {
"lcm-operation-user-data": "./UserData/userdata_standard.py",
"lcm-operation-user-data-class": "StandardUserData"
