Network Service Descriptor Management¶
To enable dynamic composition of network services, NFV introduces Network Service Descriptors (NSDs) that specify the network service to be created.
This document describes how to manage NSD with CLI in Tacker.
Prerequisites¶
The following packages should be installed:
tacker
python-tackerclient
A default VIM should be registered according to VIM Management.
The following VNFDs are created according to VNF Descriptor (VNFD) Management.
CLI reference for NSD Management¶
1. Create Network Service Descriptor¶
Create sample-tosca-nsd.yaml file:
Create a NSD:
$ openstack ns descriptor create --nsd-file \
sample-tosca-nsd.yaml <NAME: sample-tosca-nsd>
Result:
