VNF Descriptor (VNFD) Management¶
The behavioural and deployment information of a VNF in Tacker is defined in a template known as VNF Descriptor (VNFD). The template is based on TOSCA standards and is written in YAML.
This document describes how to manage VNFD with CLI in Tacker.
Prerequisites¶
The following packages should be installed:
tacker
python-tackerclient
CLI reference for VNFD Management¶
1. Create VNF Descriptor¶
Create tosca-vnfd-hello-world.yaml file:
Create a VNFD:
$ openstack vnf descriptor create --vnfd-file \
tosca-vnfd-hello-world.yaml <NAME: tosca-vnfd-hello-world>
Result:
