ETSI NFV-SOL VNF Change Current VNF Package¶

This document describes how to change current VNF package for VNF in Tacker v2 API.

Note

The content of this document has been confirmed to work using the following VNF Packages.

Please also refer to the samples below.

If you use the samples, you need to add the following files:

Definitions/etsi_nfv_sol001_common_types.yaml
Definitions/etsi_nfv_sol001_vnfd_types.yaml
Files/images/cirros-0.5.2-x86_64-disk.img

The samples make the following updates:

VDU1
- change image
- change network
VDU2
- change image
- change flavor
VDU3
- no change

Overview¶

The diagram below shows an overview of changing current VNF package.

Request Change Current VNF Package

A user requests tacker-server to change current VNF package for VNF instance with tacker-client by requesting change current vnf package.
Call OpenStack Heat API

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 OpenStack infra-driver) according to the contents of VNF instance. Then, OpenStack infra-driver calls OpenStack Heat APIs.
Change the image of VMs

OpenStack Heat change the image of VMs according to the API calls.

Prerequisites¶

The following packages should be installed:

tacker
python-tackerclient

At least one VNF instance with status of INSTANTIATED is required. You can refer to ETSI NFV-SOL VNF Deployment as VM with LCM Operation User Data for the procedure to instantiate VNF.

You can refer to VNF Package for the operation of uploading VNF package.

Note

You can deploy a VM directly by image or volume. Therefore, when updating the image of the VM, there will be two cases.

Use the common VNF package and the flavor_id to instantiate, and then use the VNF package in the corresponding link to execute change current vnf package operation, you can update the image of the VM in the following two ways.

change VM created by image to VM created by new image
change VM created by volume to VM created by new volume

Change Current VNF Package¶

As mentioned in Prerequisites, the VNF must be created before performing change current VNF package.

You need to upload the VNF package you want to change to before executing change current vnf package.

Details of CLI commands are described in VNF Lifecycle Management with v2 Tacker.

For changing current VNF package, you need to prepare a JSON-formatted definition file before running command for changing the VNF package.

> password	1	Password of load balancer server.
lcm-operation-user-data	0..1	File name of UserData to use.
lcm-operation-user-data-class	0..1	Class name of UserData to use.

Note

sample_param_file.json can be used to change image for both VDU created by OS::Heat::AutoScalingGroup and single VDU.

vnfdId is the VNFD id of the new VNF package you uploaded.
lcm-operation-coordinate-old-vnf and lcm-operation-coordinate-new-vnf are unique implementations of Tacker to simulate the coordination interface in ETSI SOL002 v3.6.1. Mainly a script that can communicate with the VM after the VM is created, perform special customization of the VM or confirm the status of the VM.
vimConnectionInfo is an optional parameter. 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. It is not possible to delete the key of registered vimConnectionInfo.
vnfConfigurableProperties and extensions are optional parameter. As with the update operation, these values are updated by performing JSON Merge Patch with the values set in the request parameter to the current values. For metadata, the value set before this operation is maintained.
extVirtualLinks is an optional parameter. This operation can change external CP for the VNF instance.

Note

Currently, this operation only supports some functions of Change Current VNF Package.

There are several ways to update VDUs, but Bobcat version Tacker only supports RollingUpdate type. You can set it via upgrade_type param.
Currently only support update images of VMs and modify external networks.
Currently unsupported updates:
- This API currently does not support increasing or decreasing the number of VNFcs according to the VNF package.
- The add and delete operations of the entire VDU are not supported.
- In the definition of ETSI, external and internal networks (e.g. extVirtualLinks, extManagedVirtualLinks) can be modified. This current API supports the operations of modifying external networks only and does not support the following operations.
  - Adding and deleting external networks.
  - Modifying, adding, and deleting internal networks.

How to Change VM created by image to VM created by new image¶

Execute Change Current VNF Package CLI command. After complete this change operation you should check resource status by Heat CLI commands.

1. check ‘ID’ and ‘Stack Status’ of the stack before and after operation. This is to confirm that stack ‘ID’ has changed before and after operation, and that the Stack update has been updated successfully.

2. check ‘physical_resource_id’ and ‘resource_status’ of the VDU and VDU’s parent resource. This is to confirm that ‘physical_resource_id’ has no change before and after operation, and that the resource_status has been updated successfully.

3. check ‘image’ information of VDU before and after operation. This is to confirm that VDU’s has changed successfully. See Heat CLI reference. for details on Heat CLI commands.

Note

Both single VM and VM created by OS::Heat::AutoScalingGroup support change from image to image. The single VM is created directly by OS::Nova::Server defined in the top heat template.

How to Change VM created by volume to VM created by volume¶

Execute Change Current VNF Package CLI command. After complete this change operation you should check resource status by Heat CLI commands.

2. check ‘physical_resource_id’ and ‘resource_status’ of the VDU and VDU’s parent resource. This is to confirm that ‘physical_resource_id’ of VDU has changed before and after operation, ‘physical_resource_id’ of VDU’s parent resource has no change before and after operation, and that the ‘resource_status’ of VDU has been created successfully, ‘resource_status’ of VDU’s parent resource has been updated successfully,

3. check ‘volume’ information of VDU before and after operation. This is to confirm that VDU’s has changed successfully.

Note

Both single VM and VM created by OS::Heat::AutoScalingGroup support change from volume to volume.
