VNF Lifecycle Management

This document describes how to manage VNF Lifecycle with CLI in Tacker.

Prerequisites

The following packages should be installed:

  • tacker

  • python-tackerclient

A default VIM should be registered according to VIM Management.

CLI Reference for VNF Lifecycle Management

Note

Commands call version 1 vnflcm APIs by default. You can call the specific version of vnflcm APIs by using the option --os-tacker-api-version. Commands with --os-tacker-api-version 2 call version 2 vnflcm APIs.

Note

In Yoga release, version 2 vnflcm APIs of instantiate vnf, terminate vnf, scale vnf, heal vnf, change external vnf connectivity, rollback, retry and fail only support VNF, not CNF. CNF will be supported by version 2 vnflcm APIs in future releases.

1. Create VNF Identifier

The VNFD_ID should be replaced with the VNFD ID in VNF Package. In the following sample, b1bb0ce7-ebca-4fa7-95ed-4840d70a1177 is used.

$ openstack vnflcm create VNFD_ID
