5G - PNF Plug and Play
----------------------
Source files
~~~~~~~~~~~~
- Base PnP PNF Simulator heat template file: https://git.onap.org/integration/tree/test/mocks/pnfsimulator/deployment/PnP_PNF_sim_heat_template_Ubuntu_16_04.yml
Description
~~~~~~~~~~~
The PNF PnP flow is a method, which allows to register within ONAP/AAI a PNF resource instance.
This PNF resource instance is correlated with an existing service instance.
PNF Plug and Play is used to register a PNF when it comes on-line.
This use case is intended to be applicable to a variety of PNFs such as routers and 5G base stations.
The steps and descriptions have been drafted to be as general as possible and to be applicable
to a relatively wide variety of PNFs. However, the use case was originally developed with a consideration
for 5G PNF Distributed Units (DU).

How to Use
~~~~~~~~~~
1) `Create and distribute service model which contains PNF <https://wiki.onap.org/display/DW/5G+-+PNF+PnP+-+Integration+Test+Cases#id-5G-PNFPnP-IntegrationTestCases-CreateanddistributeservicewhichcontainsPNF>`_
2) `Create service for PNF and wait for PNF Ready message in DmaaP topic <https://wiki.onap.org/display/DW/5G+-+PNF+PnP+-+Integration+Test+Cases#id-5G-PNFPnP-IntegrationTestCases-PNFReady>`_
3) `Send PNF Registartion request from PnP PNF Simualtor and finish registration <https://wiki.onap.org/display/DW/5G+-+PNF+PnP+-+Integration+Test+Cases#id-5G-PNFPnP-IntegrationTestCases-PNFregistrationacceptingwhenAAIentrycreatedinadvance>`_
Known Issues and Resolutions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In SO BPMN in mechanism making re-subscription to /events/unauthenticated.PNF_READY topic there is an issue `SO-1253 <https://jira.onap.org/projects/SO/issues/SO-1253>`_.
By default after ONAP and PRH deploy DMaaP topic /events/unauthenticated.PNF_READY is not present.
It is created by PRH after first expected PNF registration event arrival to ONAP system.
If service for PNF will be created before topic /events/unauthenticated.PNF_READY will be present then service will not be able to read from the topic.
**Workaround**
- Before starting any PNF service verify if unauthenticated.PNF_READY topic exists using command:
::
curl --header "Content-type: application/json" --request GET http://<kubernetes slave IP>:30227/topics/listAll
- If it doesn't exists send following curl in order to create topic:
::
curl --header "Content-type: application/json" --request POST --data '[{"correlationId": "test"}]' http://<kubernetes slave IP>:30227/events/unauthenticated.PNF_READY
- Once again verify if topic exists
- If the PNF service will be started before unauthenticated.PNF_READY topic creation, then there will be a need to restart SO-BPMN docker container
