Introduction

This document explains the steps to on-board and instantiate vFW on Azure

Pre-requisites

ONAP environment on Azure as explained here

Demo Video

Refer to the video on how to on-board and instantiate vFW on Azure(E2E)

Error rendering macro 'multimedia' : com.atlassian.renderer.v2.macro.MacroException: Cannot find attachment 'vfw_on_azure.mp4'

The detailed steps are provided below:

Onboarding and Service Design

Onboard the vSINC VNF using the TOSCA designed using Simple profile nodes. TOSCA csar is available on Github: https://github.com/onapdemo/demo/blob/beijing/tosca/aria_csars/simple_vfw_vSNC.csar?raw=true
Onboard the vPG VNF using the TOSCA designed using Simple profile nodes. TOSCA csar is available on Github: https://github.com/onapdemo/demo/blob/beijing/tosca/aria_csars/simple_vfw_vPG.csar?raw=true
Import the vSINC VSP and create the VNF as shown in the video
After creating the VNF, use the deployment artifact link to add the Azure specific TOSCA in the OTHER folder.
1. Azure specific TOSCA for vSINC is available on Github: https://github.com/onapdemo/demo/blob/beijing/tosca/aria_csars/azurevsnk.csar?raw=true
Similarly, import the vPG VSP and add the Azure specific TOSCA
1. Azure specific TOSCA for vPG is available on Github: https://github.com/onapdemo/demo/blob/beijing/tosca/aria_csars/azurevpkg.csar?raw=true
Using SDC catalog, create the vFW service by adding two VNFs that were imported.
Distribute the service to SO and AAI
Naming of CSAR files

The csar names of aria TOSCA should be same as in github. This allows the Multivim adapter to pick up the correct TOSCA file for instantiation

Service Provisioning

Once the service model gets distributed to SO & AAI, service instantiation can be done using VID UI

Pre-requisites

Refer to pre-requisites page.

Steps to instantiate

Login to VID and click on Browse Service Models(Left menu)
Click on Deploy and then enter the service instance name and other details to create the service.
Once created, you can see the service instance details with an option to "Add VNF".
Click on Add VNF and select the VNF module related to vSINC.Enter the VNF name: "zdfw1fwl01vfw01" and other details to create the VNF for vSINC.
The VNF name should be same as mentioned in above step to run the Closed loop.

In preload parameters, repo_url_blob,repo_url_artifacts refers to Github link where the modified scripts for vSINC and vFW installation are kept.

{
"vnf-parameter-name": "repo_url_blob",
"vnf-parameter-value": "https://raw.githubusercontent.com/onapdemo/onap-scripts/master/usecases"
},

{
"vnf-parameter-name": "repo_url_artifacts",
"vnf-parameter-value": "https://raw.githubusercontent.com/onapdemo/onap-scripts/beijing"
}

Also, update the dcae_collector_ip(Load Balancer IP) in the request body to initiate Closed loop.

Click on Add VF module.Enter the details and submit the request. This will instantiate the FW and SINC VMs on Azure
Similarly,follow step 4(select vPG module related to vPG) and create the VNF for vPG.

In preload parameters, repo_url_blob refers to Github link where the modified scripts for vPG installation are kept.

{
"vnf-parameter-name": "repo_url_blob",
"vnf-parameter-value": "https://raw.githubusercontent.com/onapdemo/onap-scripts/master/usecases"
}

Also, update the dcae_collector_ip(Load Balancer IP) in the request body to initiate Closed loop.

Click on Add VF module.Enter the details and submit the request. This will instantiate PG on Azure.

Traffic flow test

Open the browser and enter the URL: http://vsnctestapp.eastus.cloudapp.azure.com:667

This will show the graph with the packets coming to SINC vm

ClosedLoop Execution

Once the instantiation of vFW is done, the VES agent in vFW VM will send the measurement data to DCAE using the IP and Port given in Preload parameters.

Two manual steps are needed to run the closed loop flow which are mentioned below:

Push polices
First go through below link and validate the health of the policy pods.
https://lf-onap.atlassian.net/wiki/display/DW/Policy+on+OOM
Then do these steps
1. Go to pap container
2. Go to /tmp/policy-install/config/
3. execute command "export PRELOAD_POLICIES=true"
4. copy push-policies.sh to /tmp
5. Go to /tmp and open push-policies.sh
6. Go to vid and search the service instance and then take the "model id" of vPG vnf.
7. find resourceID in the push-policies.sh and change its value to "model id" of vPG (shown as below)
curl -v --silent -X PUT --header 'Content-Type: application/json' --header 'Accept: text/html' --header 'ClientAuth: cHl0aG9uOnRlc3Q=' --header 'Authorization: Basic dGVzdHBkcDphbHBoYTEyMw==' --header 'Environment: TEST' -d '{

Create APPC Mount
1. Get the VNF instance ID of vPG, either through VID or through AAI.
2. Get the public IP address of the Packet Generator from your deployment.
3. Create file appc-mount.xml with following content and replace VPG_IP with packet generator IP.
  <node xmlns="urn:TBD:params:xml:ns:yang:network-topology">
  <node-id>VPG_VNF_INSTANCE_ID</node-id>
  <host xmlns="urn:opendaylight:netconf-node-topology">VPG_IP</host>
  <port xmlns="urn:opendaylight:netconf-node-topology">2831</port>

  <keepalive-delay xmlns="urn:opendaylight:netconf-node-topology">120</keepalive-delay>
  </node>
4. Create Network config in appc using below API
  curl -v --user "admin":"admin" -d @appc-mount.xml -H "Accept: application/xml" -H "Content-type: application/xml" -X PUT http://<load_balancer_ip>:30230/restconf/config/network-topology:network-topology/topology/topology-netconf/node/<VNF_INSTANCE_ID>
5. Use below GET to validate that PUT API created config correctly
  curl -v --user "admin":"admin" -H "Accept: application/xml" -H "Content-type: application/xml" -X GET http://<load_balancer_ip>:30230/restconf/config/network-topology:network-topology/topology/topology-netconf/node/<VNF_INSTANCE_ID>

Running vFW with Robot Framework

This vFW automation handles model creation and instantiation.

Run the vFW script as following:

Connect to the Azure VM where ONAP is deployed via SSH and execute the following commands:

[root@onap-tanmay:/home/ubuntu/oom/kubernetes/robot]# cd /opt/aee/oom/kubernetes/robot/
[root@onap-tanmay:/home/ubuntu/oom/kubernetes/robot]# ./demo-k8s.sh instantiateAzureVFW

Output of the Execution-

Console -

Azure Portal -

Log-

vFW on Azure

Additional information

Based on the preferences, User can modify following files to instantiate vFW on Azure.

1. integration_preload_parameters.py
  This file is available under /dockerdata-nfs/<namespace>/robot/eteshare/config/ in Azure VM where ONAP is deployed. User can modify preload parameters for vFW Instantiation under - "azurevfwsnk_preload.template" and "azurevpkg_preload.template".
2. integration_robot_properties.py
  This file is available under /dockerdata-nfs/<namespace>/robot/eteshare/config/ in Azure VM where ONAP is deployed. User can modify fields such as "AZURE_SUBSCRIPTION_ID" , "AZURE_TENANT_ID" , "AZURE_CLIENT_ID" , "AZURE_CLIENT_SECRET" , "AZURE_CLOUD_OWNER" , "AZURE_CLOUD_REGION"

Make sure you compile these python file after any modification using command - python <filename>
