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
Xena release does not support version 2 vnflcm APIs of scale vnf, heal vnf, change external vnf connectivity, rollback, retry and fail. The version 2 of these APIs will be supported in future releases. Also, in Xena release, version 2 vnflcm APIs of instantiate vnf and terminate vnf 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
