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

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
