PNF Simulator Day-N config-assign and config-deploy use case

The objective of this page is to give you some basics about setting up ONAP PNF simulator and how to create a simple CDS blueprint model to perform DAY-N config-assign and config-deploy.

Setting up PNF simulator integration project

You can refer to PnP PNF Simulator wiki page to clone the GIT repo and start the required docker containers. We are interested in the sysrepo/sysrepo-netopeer2 docker container to load a simple YANG similar to vFW Packet Generator.

Start PNF simulator docker containers. You can consider changing the netopeer image verion to image: sysrepo/sysrepo-netopeer2:iop in docker-compose.yml file If you find any issues with the default image.

cd $HOME

git clone https://github.com/onap/integration.git

Start PNF simulator

cd ~/integration/test/mocks/pnfsimulator

./simulator.sh stop

Verify the you have netopeer docker container are up and running. It will be mapped to host port 830

docker ps -a | grep netopeer

Create a simple packet generator YANG model (pg.yang)

module sample-plugin {

yang-version 1;
namespace "urn:opendaylight:params:xml:ns:yang:sample-plugin";
prefix "sample-plugin";

description
"This YANG module defines the generic configuration and
operational data for sample-plugin in VPP";

revision "2016-09-18" {
description "Initial revision of sample-plugin model";
}

container sample-plugin {
uses sample-plugin-params;
description "Configuration data of sample-plugin in Honeycomb";

// READ
// curl -u admin:admin http://localhost:8181/restconf/config/sample-plugin:sample-plugin

// WRITE
// curl http://localhost:8181/restconf/operational/sample-plugin:sample-plugin

}

grouping sample-plugin-params {
container pg-streams {
list pg-stream {

key id;
leaf id {
type string;
}

leaf is-enabled {
type boolean;
}
}
}
}
}

Sample XML data definition for the above model to initialise one single PG stream (pg-data.xml)

<sample-plugin xmlns="urn:opendaylight:params:xml:ns:yang:sample-plugin"> <pg-streams> <pg-stream> <id>1</id> <is-enabled>true</is-enabled> </pg-stream> </pg-streams> </sample-plugin>

Copy the above two files into netopeer docker container (pg.yang & pg-data.xml) under /etc/sysrepo/data folder

Execute the following command within netopeer docker container to install the pg.yang model

sysrepoctl -i -g /etc/sysrepo/yang/pg.yang

Connect to netopeer docker container and execute the following commands to initialise the pg.yang model. You can leave this terminal up and running.

In the below steps we just initialise the Yang model with one pg-stream record. We will be using CDS to perform the day-1 configuration and day-2 configuration changes.

cd /opt/dev/Netopeer2/cli/build
./netopeer2-cli
> connect --host localhost --login netconf
> edit-config --target running --config=/dev-models/pg-data.xml
> get --filter-xpath /sample-plugin:*

> edit-config --target running --config=/dev-models/sample-plugin-data.xml
OK
> get --filter-xpath /sample-plugin:*
DATA
<sample-plugin xmlns="urn:opendaylight:params:xml:ns:yang:sample-plugin">
<pg-streams>
<pg-stream>
<id>1</id>
<is-enabled>true</is-enabled>
</pg-stream>
</pg-streams>
</sample-plugin>

You can use the attached PNF-DEMO-ENRICHED-CBA.zip file to enrich, save, publish and deploy from CDS UI. Otherwise you can clone the CDS source code

git clone "https://gerrit.onap.org/r/ccsdk/cds"

Setup CDS k8s environment by following Running CDS on Microk8s wiki page

After Verify if you can see CDS k8s PODs

kubectl get pods -n onap

CDS Boot strap

The below script will load the CDS model artifacts into CDS DB. You should get HTTP status 200 for the below command.

cd PNF_DEMO/Scripts/

bash -x ./bootstrap-cds.sh

Get the default model "artifactName": "vFW-CDS" loaded by bootstrap

bash -x ./get-cds-blueprint-models.sh

Load PNF CDS blueprint model data dictionary

cd PNF_DEMO/Scripts

bash -x ./dd-microk8s.sh ./dd.json

Check CDS database for PNF data dictionaries

You should see 6 rows as shown below

./connect-cds-mariadb.sh

select name, data_type from RESOURCE_DICTIONARY where updated_by='Aarna service <vmuthukrishnan@aarnanetworks.com>';

quit

exit

Create PNF CDS Blueprint archive pnf-demo.zip

cd PNF_DEMO/

rm pnf-demo.zip

zip -r pnf-demo.zip *

# You should see the below ZIP file
ls -l pnf-demo.zip

Enrich PNF Bluerprint archive

cd PNF_DEMO/Scripts

bash -x ./enrich-and-download-cds-blueprint.sh ../pnf-demo.zip

Verify Enriched Blue pring archive /tmp/CBA/ENRICHED-CBA.zip

cd /tmp/CBA/

unzip ENRICHED-CBA.zip

tree

Deploy/Save the Blueprint into CDS database

cd PNF_DEMO/Scripts
bash -x ./save-enriched-blueprint.sh ../pnf-demo.zip

# You should see the new model "artifactName": "pnf_netconf"
bash -x ./get-cds-blueprint-models.sh

Config-Assign

# The assumption is that we are using the same host to run PNF NETCONF simulator as well as CDS
# bash -x ./create-config-assing-data.sh day-1 LOCAL_HOST_IP_ADDRESS 5

Create PNF configuration for day-1 (stream-count = 5)

You can verify the CURL command JSON pay load file /tmp/day-n-pnf-config.json

cd PNF_DEMO/Scripts

bash -x ./create-config-assing-data.sh day-1 10.128.0.86 5

Verify the day-1 NETCONF RPC payload in CDS DB you should see the NETCONF RPC with 5 streams (fw_udp_5)

./connect-cds-mariadb.sh

MariaDB [sdnctl]> select * from TEMPLATE_RESOLUTION where resolution_key='day-1' AND artifact_name='netconfrpc';

Create PNF configuration for day-2 (stream-count = 10)

Config-Deploy

config-deploy request will send the Day-0 or Day-1 resolution key as part of the REST call.

"resolution-key" : "day-1" (OR) "resolution-key" : "day-2"

config-deploy should retrieve the Day-1 or Day-2 configuration based on the resolution-key and executes the NETCONF command processor Kotlin code
