...
Once the stack is created, the vBNG configuration file is deployed to the instance to '$HOME/vbng.conf' and latest vBNG code is directly pulled from specified upstream git repository (default is the Swisscom repository) by cloud-init user-data script. The stack output shows initial vBNG configuration, the floating IP and how to connect to the instance by SSH. To create a stack in OpenStack heat you first require the Heat template from here: https://git.swisscom.com/projects/ZTXGSPON/repos/opnfv/browse/heat/vbng.yaml (Drop a note to michail salichos, David Perez Caparros or Daniel Balsiger in case you do not have access)

Create docker images and start all containers: Database, Message Queue, Restconf Server, VES Agent and DHCP Server.
OLT
...
Configuration
OLT onboarding configuration is not done by cloud-init, since OLT parameters are normally not known at stack creation time. For OLT onboarding the 2 tunnels for datapath and DHCP transport and the DHCP L3 relay on the OLT have to be configured. Therefore another script should be used, once the vbng instance is provisioned initially:
vbng/03-setupolt.sh
...
With the newest version there is a REST interface for configuring OLTs. See REST API documentation below: 'POST CreateOLT', 'GET GetOLT', 'POST DeleteOLT'. To assist with working with the REST API, you can utilize Postman, and import the current API Collection.
ONT/Subscriber Configuration
Subscribers are usually configured by calls to bbs-edge-restconf-server directly from ONAP. In case you would like to test this functionality you can of course trigger this directly with the REST API calls defined below.
Important parameters are: "remote_id":"AC9.000.990.001","s_vlan":10,"c_vlan":333 .Of course the values configured must match what the OLT/ONT in the Lab sends.
Currently only 4 subscribers profiles are supported (1/2/3/4), 2 * 100Mbit/s symmetrical and 2 * 20Mit/s symmetrical, respectively. This should be enough to run all test-cases for the BBS use-case.

POST CreateInternetProfileInstance
Description: Creates a subscriber instance in the vBNG. This call will be used directly by ONAP. Note, the "service_id" MUST be unique, as this is used to identify the profile for updates and deletion.

ONT/Subscriber Configuration
Subscribers are usually configured by calls to bbs-edge-restconf-server directly from ONAP. In case you would like to test this functionality you can of course trigger this directly with curl to the floating IP, TCP port 5000 of the vbng instance:
