NSD template

Defines a network service descriptor (NSD) template.

Syntax

tosca_definitions_version: tnb_simple_yaml_1_0

vnfds:
  - descriptor_id: String
    namespace: String

topology_template:

  inputs:
    SampleInputParameter:
      type: String
      description: "Sample parameter description"
      default: "DefaultSampleValue"

  node_templates:
    SampleNode1: tosca.nodes.AWS.NS

Using defined parameters

When you want to dynamically pass a parameter, such as the CIDR block for the VPC node, you can use the { get_input: input-parameter-name } syntax and define the parameters in the NSD template. Then reuse the parameter across the same NSD template.

The following example shows how to define and use parameters:

tosca_definitions_version: tnb_simple_yaml_1_0

topology_template:

  inputs:
    cidr_block:
      type: String
      description: "CIDR Block for VPC"
      default: "10.0.0.0/24"

  node_templates:
    ExampleSingleClusterNS:
      type: tosca.nodes.AWS.NS
      properties:
        descriptor_id: "a1b2c3d4-5678-90ab-cdef-EXAMPLE11111"
         .....

    ExampleVPC:
      type: tosca.nodes.AWS.Networking.VPC
      properties:
        cidr_block: { get_input: cidr_block }
