ETSI NFV-SOL CNF Deployment using Helm (v2 VNF LCM API)
This section covers how to deploy ETSI NFV-SOL containerized VNF using Helm in version 2 (v2) VNF LCM API.
Note
v1 VNF LCM API also support CNF deployment using Helm and its
requirements are different from v2 VNF LCM API. For details on using
Helm in v1 API, please refer to mgmt_driver_deploy_k8s_and_cnf_with_helm
.
Overview
The following figure shows an overview of the CNF 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 containHelm chart
in addition toVNFD
.Request instantiate VNF
A user requests tacker-server to instantiate the created VNF by requesting
instantiate VNF
with instantiate parameters.Execute Helm commands
Upon receiving a request from tacker-client, tacker-server redirects it to tacker-conductor. In tacker-conductor, the request is redirected again to an appropriate infra-driver (in this case Helm infra-driver) according to the contents of the instantiate parameters. Then, Helm infra-driver executes Helm commands.
Call Kubernetes API via Helm
Helm calls Kubernetes APIs to create Pods as a VNF.
Create Pods
Kubernetes Master creates Pods according to the API calls.
Prepare Helm VIM
1. Create a Config File
Before register a Helm VIM to tacker, we should create config file.
The following sample provides required information to register a Helm
VIM. This sample specifies the values of the bearer_token
and ssl_ca_cert
parameters that can be obtained from the
Kubernetes Master-node. For specific methods of obtaining
bearer_token
and sl_ca_cert
, please refer to1. It also contains the
extra
field. For using Helm, use_helm
in
extra
must be set as true.

Prepare VNF Package
1. Create Directories of VNF Package
TOSCA YAML CSAR file is an archive file using the ZIP file format whose structure complies with the TOSCA Simple Profile YAML v1.2 Specification. Here is a sample of building a VNF Package CSAR directory:
$ mkdir -p deployment/{TOSCA-Metadata,Definitions,Files/kubernetes}
2. Create a Helm chart
A CSAR VNF package shall have Helm chart that defines Kubernetes resources to be deployed. The file name shall have an extension of ".yaml" and all chart files shall be compressed to ".tgz".
To map Kubernetes resources defined in Helm chart to VDUs defined by VNFD, the metadata.name in Helm chart shall be described in compliance with the following rules.
metadata.name
must be set as "properties.name defiend in
VNFD"+"-" +"Unique string in the release (e.g. release name)". "Unique
string in the release" must not include "-".
The following shows the sample description.
apiVersion: apps/v1
kind: Deployment
metadata:
name: vdu1-{{ .Release.Name }}
labels:
{{- include "localhelm.labels" . | nindent 4 }
spec:
{{- if not .Values.autoscaling.enabled }}
replicas: {{ .Values.replicaCountVdu1 }}
{{- end }}
Note
In this sample, the value of replicas
is specified as
replicaCountVdu1
with the helm commands. Such a parameter
name needs to be provided as helm_value_names
in the
instantiate request parameter. A sample instantiate request parameter is
described in helm_request
.
Note
Since version 1 VNF LCM API supports using external repositories, a chart file may be contained within the VNF package or contained in external repositories. On the other hand, version 2 VNF LCM API requires Helm chart file to be contained in the VNF package.
3. Create a TOSCA.meta File
The TOSCA.Meta file contains version information for the TOSCA.Meta file, CSAR, Definitions file, and artifact file. Name, content-Type, encryption method, and hash value of the Artifact file are required in the TOSCA.Meta file. Here is an example of a TOSCA.meta file:
TOSCA-Meta-File-Version: 1.0
Created-by: dummy_user
CSAR-Version: 1.1
Entry-Definitions: Definitions/sample_cnf_top.vnfd.yaml
Name: Files/kubernetes/test-chart-0.1.0.tgz
Content-Type: test-data
Algorithm: SHA-256
Hash: 511df66c2d34bc2d3b1ea80118c4ad3c61ad7816a45bfadbb223d172b8503d30
4. Download ETSI Definition File
Download official documents. ETSI GS NFV-SOL 001 [i.4] specifies the structure and format of the VNFD based on TOSCA specifications.
$ cd deployment/Definitions
$ wget https://forge.etsi.org/rep/nfv/SOL001/raw/v2.6.1/etsi_nfv_sol001_common_types.yaml
$ wget https://forge.etsi.org/rep/nfv/SOL001/raw/v2.6.1/etsi_nfv_sol001_vnfd_types.yaml
5. Create VNFD
How to create VNFD composed of plural deployment flavours is described in VNF Descriptor (VNFD) based on ETSI NFV-SOL0012.
VNFD will not contain any Kubernetes resource information such as Connection points, Virtual links because all required components of CNF will be specified in Kubernetes resource files.
Following is an example of a VNFD file includes the definition of VNF.

6. Compress VNF Package
CSAR Package should be compressed into a ZIP file for uploading. Following commands are an example of compressing a VNF Package:
$ cd -
$ cd ./deployment
$ zip deployment.zip -r Definitions/ Files/ TOSCA-Metadata/
$ ls deployment
deployment.zip Definitions Files TOSCA-Metadata
Create and Upload VNF Package
We need to create an empty VNF package object in tacker and upload compressed VNF package created in previous section.
1. Create VNF Package
An empty VNF package could be created by command openstack vnf package create
. After create a VNF
Package successfully, some information including ID, Links, Onboarding
State, Operational State, and Usage State will be returned. When the
Onboarding State is CREATED, the Operational State is DISABLED, and the
Usage State is NOT_IN_USE, indicate the creation is successful.
$ openstack vnf package create
+-------------------+-------------------------------------------------------------------------------------------------+
| Field | Value |
+-------------------+-------------------------------------------------------------------------------------------------+
| ID | 954df00a-8b14-485d-bfd8-8fc5df0197cb |
| Links | { |
| | "self": { |
| | "href": "/vnfpkgm/v1/vnf_packages/954df00a-8b14-485d-bfd8-8fc5df0197cb" |
| | }, |
| | "packageContent": { |
| | "href": "/vnfpkgm/v1/vnf_packages/954df00a-8b14-485d-bfd8-8fc5df0197cb/package_content" |
| | } |
| | } |
| Onboarding State | CREATED |
| Operational State | DISABLED |
| Usage State | NOT_IN_USE |
| User Defined Data | {} |
+-------------------+-------------------------------------------------------------------------------------------------+
2. Upload VNF Package
Upload the VNF package created above in to the VNF Package by running
the following command openstack vnf package upload --path <path of vnf package>
<vnf package ID>
Here is an example of upload VNF
package:
$ openstack vnf package upload --path test_helm_instantiate.zip 954df00a-8b14-485d-bfd8-8fc5df0197cb
Upload request for VNF package 954df00a-8b14-485d-bfd8-8fc5df0197cb has been accepted.
3. Check VNF Package Status
Check the VNF Package Status by openstack vnf package list
command. Find the item
which the id is same as the created vnf package id, when the Onboarding
State is ONBOARDED, and the Operational State is ENABLED, and the Usage
State is NOT_IN_USE, indicate the VNF Package is uploaded
successfully.
$ openstack vnf package list
+--------------------------------------+------------------+------------------+-------------+-------------------+-------------------------------------------------------------------------------------------------+
| Id | Vnf Product Name | Onboarding State | Usage State | Operational State | Links |
+--------------------------------------+------------------+------------------+-------------+-------------------+-------------------------------------------------------------------------------------------------+
| 954df00a-8b14-485d-bfd8-8fc5df0197cb | Sample VNF | ONBOARDED | NOT_IN_USE | ENABLED | { |
| | | | | | "self": { |
| | | | | | "href": "/vnfpkgm/v1/vnf_packages/954df00a-8b14-485d-bfd8-8fc5df0197cb" |
| | | | | | }, |
| | | | | | "packageContent": { |
| | | | | | "href": "/vnfpkgm/v1/vnf_packages/954df00a-8b14-485d-bfd8-8fc5df0197cb/package_content" |
| | | | | | } |
| | | | | | } |
+--------------------------------------+------------------+------------------+-------------+-------------------+-------------------------------------------------------------------------------------------------+
Create VNF
1. Get VNFD ID
The VNFD ID of a uploaded vnf package could be found by openstack vnf package show <VNF package ID>
command. Here is an example of checking VNFD-ID value:
$ openstack vnf package show 954df00a-8b14-485d-bfd8-8fc5df0197cb

2. Execute Create VNF Command
We could create VNF by running openstack vnflcm create <VNFD ID> --os-tacker-api-version 2
.
After the command is executed, the generated ID is
VNF instance ID
.
$ openstack vnflcm create 339f9eb3-ed61-443e-8801-e7cf2474c72a --os-tacker-api-version 2

Instantiate VNF
1. Set the Value to the Request Parameter File
Get the ID of target VIM.
$ openstack vim list

| ID | Name | Tenant_id | Type | Is Default | Status |
+--------------------------------------+---------------+----------------------------------+------------+------------+-----------+

+--------------------------------------+---------------+----------------------------------+------------+------------+-----------+
A json file which includes Helm VIM information and additionalParams should be provided for instantiating a containerized VNF.
The following shows a sample json file.
{
"flavourId": "simple",
"vimConnectionInfo": {
"vim1": {
"vimId": "d0f0cef9-5890-4a68-8974-61ed71b9f5d9",
"vimType": "ETSINFV.KUBERNETES.V_1"
}
},
"additionalParams": {
"helm_chart_path": "Files/kubernetes/test-chart-0.1.0.tgz",
"helm_parameters": {
"service.port": 8081
},
"helm_value_names": {
"VDU1": {
"replica": "replicaCountVdu1"
},
"VDU2": {
"replica": "replicaCountVdu2"
}
},
"namespace": "default"
}
}
In the case of specifying vimId
in the
vimConnectionInfo
, vim information is complemented by
registered vim information.
Note
When using Helm, vimType
shall be set as
ETSINFV.KUBERNETES.V_1
. It is treated as Helm VIM inside
tacker on the basis of the value of extra.use_helm
.
Optionally, you can specify the full set of
vimConnectionInfo
, instead of registering VIM. The
following shows the sample json.
{
"vimConnectionInfo": {
"vim1": {
"vimId": "vim_id_1",
"vimType": "ETSINFV.HELM.V_3",
"interfaceInfo": {
"endpoint": "auth_url",
"ssl_ca_cert": "ssl_ca_cert"
},
"accessInfo": {
"bearer_token": "bearer_token"
}
}
}
}
Note
Even if this operation specify multiple
vimConnectionInfo
associated with one VNF instance, only
one of them will be used for life cycle management operations.
Also, a json file must include some parameters for Helm as additional parameters The following shows the additional parameters for deploying CNF by Helm chart.
+----------------------------+--------------+-----------------------------------------------------------+
| Attribute name | Data type | Parameter description |
+============================+==============+===========================================================+
|helm_chart_path | String | File path of helm_chart. |
| | | This parameter must be set |
+----------------------------+--------------+-----------------------------------------------------------+
|namespace | String | Namespace to deploy Kubernetes resources. |
| | | If absent, the value in Helm chart is used as default. |
+----------------------------+--------------+-----------------------------------------------------------+
|helm_parameters | Dict | Parameters of KeyValuePairs, |
| | | which is specified during Helm installation. |
+----------------------------+--------------+-----------------------------------------------------------+
|helm_value_names | Dict | This parameter specifies the parameter name to be set |
| | | as Helm install parameter. |
+----------------------------+--------------+-----------------------------------------------------------+
|>replica | KeyValuePairs| The parameter mapped to the number of Pods. |
| | | |
+----------------------------+--------------+-----------------------------------------------------------+
Note
The namespace
for the VNF instantiation is determined by
the following priority.
- If a
namespace
is specified in the additionalParams of the instantiate request, the specifiednamespace
is used. - If a
namespace
is not specified, the default namespace calleddefault
is used.
Warning
If the multiple namespaces are specified in the manifest by the method described in 2, the VNF instantiation will fail.
2. Execute the Instantiation Command
Run openstack vnflcm instantiate <VNF instance ID> <json file>
--os-tacker-api-version 2
to instantiate a VNF.
The VNF instance ID
is the ID generated after the openstack vnflcm create
command is executed. We can find it in the [2. Execute Create VNF
command] chapter.
$ openstack vnflcm instantiate e959ab43-133c-4c50-bb00-e2aadc66e498 helm_instantiate_req --os-tacker-api-version 2
Instantiate request for VNF Instance e959ab43-133c-4c50-bb00-e2aadc66e498 has been accepted.
3. Check the Instantiation State
We could check the Instantiation State by running the following command. When the Instantiation State is INSTANTIATED, indicate the instantiation is successful.
$ openstack vnflcm show e959ab43-133c-4c50-bb00-e2aadc66e498 --os-tacker-api-version 2 --fit-width

4. Check the Deployment in Kubernetes
We can check the deployed release by running the following command. Release is an instance of a chart running on a Kubernetes cluster.
$ helm list
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
vnfe959ab43133c4c50bb00e2aadc66e498 default 1 2022-09-13 02:14:32.389689049 +0000 UTC deployed test-chart-0.1.0 1.16.0
Also, we can check a deployed containerized VNF by running the following command. When the READY is 1/1, indicate the deployment is created successfully.
$ kubectl get deploy
NAME READY UP-TO-DATE AVAILABLE AGE
vdu1-vnfe959ab43133c4c50bb00e2aadc66e498 1/1 1 1 5m40s
vdu2-vnfe959ab43133c4c50bb00e2aadc66e498 1/1 1 1 5m40s
If we want to check whether the resource is deployed in the default
namespace, we can append -A
to the command line.
$ kubectl get deploy -A
NAMESPACE NAME READY UP-TO-DATE AVAILABLE AGE
default vdu1-vnfe959ab43133c4c50bb00e2aadc66e498 1/1 1 1 6m
default vdu2-vnfe959ab43133c4c50bb00e2aadc66e498 1/1 1 1 6m
kube-system kuryr-controller 1/1 1 1 16h
Note
If a value other than default
is specified for the
namespace during instantiate, the deployed resources will be
instantiated in the corresponding namespace.
