Installation

ONAP is meant to be deployed within a Kubernetes environment. Hence, the de-facto way to deploy CDS is through Kubernetes.

ONAP also package Kubernetes manifest as Chart, using Helm.

CDS Design time

Bellow are the requirements to enable automation for a service within ONAP.

For instantiation, the goal is to be able to automatically resolve all the HEAT/Helm variables, called cloud parameters.

For post-instantiation, the goal is to configure the VNF with initial configuration.

As part of SDC design time, when defining the topology, for the resource of type VF or PNF, you need to specify

Provide Helper scripts / tool to help with the design time activities

Here's a helper script to facilitate the deployment of data-type, data-dictionary, CBA enrichment and CBA upload.

Make sure to update the following parameters in the bellow script

NODE_IP: IP of one of the K8S cluster node

The script assume the following folder structure is in place, update the script accordingly to your environment

Code Block
└── service ├── cba ├── tmp │ └── cba.zip (temporary file) │ └── cba-enriched.zip (temporary file) ├── data-dictionary └── data-type

Note that before CDS can be used to enrich and load models, initial Data Types and Data Dictionary need to be loaded.

CDS has some own default in-build Data Types and Data Dictionary but those are not loaded by default at startup. CDS Default types and dictionary can be loaded by using CDS GUI or using API call:

Code Block

# From Frankfurt onwards inside the cluster as nodeports not exposed anymore. (Prob this can be done also from CDS GUI today)

# Find first the ClusterIp for CDS blueprints processor's http endpoint
kubectl -n onap get svc cds-blueprints-processor-http -o jsonpath='{.spec.clusterIP}'

curl -X POST --header 'Content-Type: application/json' --header 'Authorization: Basic Y2NzZGthcHBzOmNjc2RrYXBwcw==' -d '{
	"loadModelType" : true,
	"loadResourceDictionary" : true,
	"loadCBA" : false
}' http://<kube node ip>:30499<clusterIp>:8080/api/v1/blueprint-model/bootstrap

This will load Default Data Types ¹ and Default Data Dictionary ² but not demo CBA models (as 'loadCBA' is set to false).

With CBA Helper script user can load own CBA model and also own Data Types (API: /api/v1/model-type) and own Data Dictionary (API: /api/v1/dictionary) into CDS.

NOTE: CDS default Data types 1) and Data Dictionary 2) files cannot be loaded into CDS by using CDS's APIs, only CDS can load that format of files.

File format supported by /api/v1/model-type and /api/v1/dictionary APIs is not documented anywhere yet.

Card

label	instantiation

Have the HEAT template along with the HEAT environment file.

or

Have the Helm chart along with the Values.yaml file (Integration between Multicloud and CDS TBD)

Identify which template parameters are static and dynamic

Create and fill-in the a table for all the dynamic values

While doing so, identify the resources using the same process to be resolved; for instance, if two IPs has to be resolved through the same IPAM, the process the resolve the IP is the same.

Here are the information to capture for each dynamic cloud parameters

The script itself is as bellow.

The key is to have the script class derived from the framework standards.

In the case of resource resolution, the class to derive from is AbstractRAProcessor

It will give the required methods to implement: process and recover, along with some utility functions, such as set_resource_data_value or addError.

These functions either come from the AbstractRAProcessor class, or from the class it derived from.

If the resolution fail, the recover method will get called with the exception as parameter.

What is of interest is the address and id fields. For the process to return these two values, we need to create a custom data-type, as bellow

Code Block

title	dt-netbox-ip
collapse	true

{
  "version": "1.0.0",
  "description": "This is Netbox IP Data Type",
  "properties": {
    "address": {

    "id": {
      "required": true,
      "type": "integer"
    }
  },
  "derived_from": "tosca.datatypes.Root"
}

The type of the data dictionary will be dt-netbox-ip.

To tell the resolution framework what is of interest in the response, the output-key-mapping section is used. The process will map the output-key-mapping to the defined data-type.

Understand resource accumulator templates

These templates are specific to the instantiation scenario, and relies on GR-API within SDNC.

The resource accumulator template is composed of the following sections:

Anchor

`resource-accumulator-resolved-data`

Defines all the resources that can be resolved directly from the context. It expresses a direct mapping between the name of the resource and its value.

  ]

`Anchor raTemplatesCD raTemplatesCD`

`capability-data`

Defines the logic to use to create a specific resource, along with the ingredients required to invoke the capability and the output mapping. See the ingredients as function parameters, and output mapping as returned value.

The logic to resolve the resource is a DG, hence DG development is required to support a new capability.

Currently the following capabilities exist:

Netbox: netbox-ip-assign

Required templates

See Modeling Concepts#template

The name of the templates is very important, and can't be random. Bellow are the requirements

VNF

The VNF Resource Accumulator Template prefix name can be anything, but what is very important is that when integrating with SDC the sdnc_artifact_name property of the VF or PNF needs to be the same; see here.

VF-Modules

Each vf-module will have its own resource accumulator template, and its prefix name must be the vf-module-label, which is nothing but the name of the HEAT file defining the OS::Nova::Server

Example:

If the file is name vfw.yaml, the vf-module-label will be vfw

For instance, with the vFW service HEAT definition, you will see in the VSP within SDC the following screen, showing you the label of each vf-module

In this case, we will have 4 resource accumulator templates, following the template convention, hence ending with -template

base_template-template.vtl
vfw-template.vtl
vsn-template.vtl
vpg-template.vtl

Mapping

Each template requires its associated mapping file, see Modeling Concepts#ArtifactMappingResource

Example:

Taking the same vFW example, we would have 4 mapping template following the convention, hence ending with -mapping:

vfw-mapping.vtl
vsn-mapping.vtl
vpg-mapping.vtl

template-prefix

SDNC will populate this input with the name of the template to execute.

If doing VNF Assign, it will use sdnc_artifact_name as template-prefix.

If doing VF-Module Assign, it will use the vf-module-label as template-prefix.

Output

It is necessary to provide the resolved template as output. To do so, we will use the Modeling Concepts#getAttribute expression.

Also, as mentioned here Modeling Concepts#resourceResolution, the resource resolution component node will populate an attribute named assignment-params with the result.

Finally, the name of the ouput has to be meshed-template so SDNC GR-API knows how to properly parse the response.

Anchor
raComponent
raComponent

Component

This action requires a node_template of type component-resource-resolution

The name of the node_template is important, as it will be used within the Workflow definition (see step.target property Modeling Concepts#workflowProperties)

Finally, you can see the component has a list of artifacts, being the template/mapping defined before.

Example:

Taking the same vFW example, we have a node_template name resource-assignment:

  2. call self-serve-vf-module-assign
    1. set capability.execution-order
    2. call self-serve-vfmodule-ra-assignment
      1. execute REST call to CDS blueprint processor
        put resource-accumulator-resolved-data in MDSAL GR-API/services/service/$serviceInstanceId/vnfs/vnf/$vnfId/vf-modules/vf-module
    3. call self-serve- + capability-name
  3. put vf-module information in AAI

template-prefix

Name of the template-prefix to resolve.

Code Block
"template-prefix" : { "required" : true, "type" : "list", "entry_schema" : { "type" : "string" }

resolution-key

The functionality requires the ability to retrieve the resolution that has been made later point in time in the process, during config-deploy action.

Code Block
"resolution-key" : { "required" : true, "type" : "string" }

Output

In order to perform dry-run, it is necessary to provide the meshed resolved template as output. To do so, the use of Modeling Concepts#getAttribute expression is required.

Also, as mentioned here Modeling Concepts#resourceResolution, the resource resolution component node will populate an attribute named assignment-params with the result.

Anchor
ConfigAssignComponent
ConfigAssignComponent

Component

This action requires a node_template of type component-resource-resolution

The name of the node_template is important, as it will be used within the Workflow definition (see step.target property Modeling Concepts#workflowProperties)

Finally, you can see the component has a list of artifacts, being the template/mapping defined before.

Example:

Taking the vDNS example, we have a node_template name config-assign:

Templates

If need be, some template can be defined. They can either be resolved through the a node_template of type component-resource-resolution,which will then have to be combined with another node_template, in order to push the config in the network, or in third party system. In this case, you will want to leverage the multi-action worklow.

Else, the template could be resolved directly through a node_template of type component-script-executor through helpers functions being provided.

Component

If you want to have a multi-action worklow, then the action will refer to a node_template of type dg-generic.

If you want to have a single action workflow, then you should use one of the following node type: component-script-executor, component-remote-script-executor, component-remote-ansible-executor

The name of the node_template is important, as it will be used within the Workflow definition (see step.target property Modeling Concepts#workflowProperties)

Finally, you can see the component(s) might have a list of artifacts, being the template/mapping defined before.

Example:

Taking the vDNS example, we have a node_template name config-deploy-process, which is of type dg-generic, hence we also have the dependent node_template.

Introduction

The purpose is to describe integration of CDS within SDC

What's new

At the VF and PNF level, a new artifact type CONTROLLER_BLUEPRINT_ARCHIVE allow the designed to load the previsouly designed CBA as part of the resource.

Anchor

How to add the CBA in SDC VF resource (similar for PNF)

Create the VF resource

Click on Deployment Artifact, then Add other arifacts, and select you CBA

Check the artifact is uploaded OK, and click on Certify.

Create a new service model, and add the newly created VF (including CBA artifact) to the new service model. Click on "Add Service"

Click on "Composition", and drag the VF we created from the palette on the left onto the canvas in the middle.

Then, click on "Submit for Testing".

Anchor

	SDC_CBA_PROPERTIES
	SDC_CBA_PROPERTIES

Click on Properties Assignments, then click on the service name, e.g. "CDS-VNF-TEST" from the right bar.

Type "sdnc" in the filter box, and add the sdnc_model_name, sdnc_model_version, and sdnc_artifact_version, and click "Save".

sdnc_model_name - This is the name of the blueprint (e.g. CBA name)
sdnc_model_version - This is the version of the blueprint
sdnc_artifact_name - This is the name of the VNF resource accumulator template

Type "skip" in the filter box, and set "skip post instantiation" to FALSE, then click "Save".

Login as Tester (jm0007/demo123456!) and accept the new service.

Login as Governor (gv0001/demo123456!) and approve for distribution.

Login as Operator (op0001/demo123456!) and click on "Distribute".

Click on "Monitor" to check the progress of the distribution, and check that all ONAP components were notified, and downloaded the artifacts, and deployed OK.
