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 -> NF 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.sysrepo-netopeer2 docker container to load a simple YANG similar to vFW Packet Generator.

You can also consider using the Netopeer docker container alone to bring up NETCONF server. You can download the docker compose file test-netopeer.tar.gz

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.

...

./simulator.sh stop

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

...

cd /opt/dev/Netopeer2/cli/build
./netopeer2-cli

> edit-config --target running --config=/dev-models/pg-data.xml
> get --filter-xpath /sample-plugin:*

You can use the attached either plain CBA file (pnf-demo-unenriched.zip) or the enriched (PNF-DEMO-ENRICHED-WORKING.zip) file to enrich, save, publish and deploy from CDS UI. Otherwise you can clone the CDS source code using utility scripts under Scripts folder

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

...

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

...

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-2 10.128.0.86 10

Verify the day-2 NETCONF RPC payload in CDS DB you should see the NETCONF RPC with 5 streams (fw_udp_1 TO fw_udp_10)

MariaDB [sdnctl]> select * from TEMPLATE_RESOLUTION where resolution_key='day-2' AND artifact_name='netconfrpc';

Note:- Till this point CDS did not interact with the PNF simulator or device. We just created the day-1 and day-2 configurations and

...

Open a new terminal and tail CDS Blueprint processor logs and keep it running. We will need it to review the config-deploy actions

cd PNF_DEMO/Scripts

bash -x ./tail-cds-bp-log.sh

Push the NETCONF changes for day-1

# Command syntax
# bash -x ./process-config-deploy.sh RESOLUTION_KEY PNF_IP_ADDRESS
# resolution-key = day-1 you can look at the JSON payload /tmp/pnf-config-deploy.json

cd PNF_DEMO/Scripts

bash -x ./process-config-deploy.sh day-1 10.128.0.86

Verify the CDS blueprint processor logs and you should see NETCONF RPC OK response as shown below
