  1. Onboard the vDNS VNF using the TOSCA designed using Simple profile nodes. TOSCA csar is available on  Github: https://github.com/onapdemo/demo/rawblob/masterbeijing/tosca/aria_csars/simple_vdns.csar?raw=true 
  2. Import the vDNS VSP and create the VNF as shown in the video
  3. After creating the VNF, use the deployment artifact link to add the Azure specific TOSCA in the OTHER folder.
    1. Azure specific TOSCA for for base vDNS is  is available on Github: https://github.com/onapdemo/demo/blob/beijing/tosca/aria_csars/azurevdns.csar?raw/master=true
    2. Azure specific TOSCA for DNS scaling is available on Github: https://github.com/onapdemo/demo/blob/beijing/tosca/aria_csars/aria-vdnsdnsscaling.csar?raw=true
  4. Using SDC catalog, create the vDNS service by adding two VNFs that were imported.
  5. Distribute the service to SO and AAiAAI

Service Provisioning

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

Pre-requisites 

Refer to Pre-requisitesto vDNS on Azure page

Steps to instantiate

  1. Login to VID and click on Browse Service Models(Left menu)
  2. Click on Deploy and then enter the service instance name and other details to create the service.
  3. Once created, you can see the service instance details with an option to "Add VNF".
  4. Click on Add VNF and select the VNF module.Enter the VNF name and other details to create the VNF.
  5. Preload SDNC data by capturing the VNF model data information
    1. POST /restconf/operations/VNF-API:preload-vnf-topology-operation

  6. Click on Add VF module.Enter the details and submit the request. This will instantiate the PG(Packet The vf-module should match the naming convention : "Vfmodule_<ANY_STRING>". This ensures the Policy to create the vf-module name for the scaling by replacing "Vfmodule_" to "vDNS_"
  7. Enter the details and submit the request. This will instantiate the PG(Packet Generator), LB(Load Balancer) and DNS VMs on Azure

...

  1. SSH to PG VM.
    1. ssh ubuntu@vpgtestapp.eastus.cloudapp.azure.com 
    2. Password: Qwertyuiop@@1

  2. Execute the command: nslookup host1.dnsdemo.onap.org 172.23.9.111 


  3. sudo tcpdump -i eth1

ClosedLoop Execution

The closed loop flow in case vDNS spawn a new DNS server based on the event trigger generated by DCAE.

Steps to create ClosedLoop

  1. Push policies

    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. execute push-policies.sh (./push-policies.sh)

  2. Preload vDNS scaling data in SDNC. As mentioned in earlier section, the vnf-name should prepend with "vDNS_"
