 Instantiate Service, VNF, VF modules and Network
 ================================================


 Overview
 --------

 Using VID with A-La-Carte method means that the user needs to performed
 by himself the instantiation of each object: service, VNF(s), VF module(s),
 network(s).

 ONAP to VIM interactions will occurs when instantiating/deleting VF module(s)
 or Network(s). In case of an Openstack VIM, Heat Stack(s) will
 be created/deleted.

 In the following description, the service model in SDC was composed of 1 VF
 and 1 Virtual Link (Generic Neutron Network)

 .. note::
    For doing this make sure that while Service Design drag the created VF and Generic NetronNet Virtual Link (under Generic/Network Elemntes list) from the
    Elements palette to the canvas then connect as mentoned in Create Service section of Service Design under Composition

 To be able to instantiate VF-module or Network object, some data need to be
 declared in ONAP SDNC using SDNC Rest API. It is the place where to put
 the instance specific values such as an IP address value specific
 to the VNF instance for example.

 In VID, terminologies are sometimes different than in other components:

 VNF in VID  = VF in SDC

 Node instance = VF in SDC

 Network = Virtual Link in SDC


 Pre-requisites
 --------------

 Pre-instantiation operations must have been performed in AAI and VID,
 via Rest API, to declare some values for:

 - Subscriber Name (= customer in AAI)
 - Service Type or product family (= service subscription in AAI)
 - Project
 - Owning Entity
 - Line Of Business
 - Platform
 - LCP Region (= CloudOwner/RegionId in AAI)
 - Tenant

 See, in the ONAP User Guides, section about adding a CloudSite
 and section about pre-instantiation Operations

 .. note::
    Robot demo script will be used to populate demo models automatically with Demonstration as Subscriber Name in VID by running "demo-k8s.sh onap init"

 Access to VID portal
 --------------------

 .. figure:: images/onap-portal.png
    :align: center

 Select the VID icon

 .. figure:: images/vid-icon-on-portal.png
    :align: center


 Here after, the VID Home page starts

 .. figure:: images/home.png
    :align: center


 SDNC API selection
 ------------------

 Select the API for "A-la-carte"

 There are two choices:

 - VNF_API (old) : VID will use the (old) "VNF" SDNC API
   to get/check some parameters
 - GR_API (new) : VID will use the "Generic Resource"
   SDNC API to get/check some parameters

 .. figure:: images/API_selection.png
    :align: center


 Instantiate Service in "A-la-carte" mode
 ----------------------------------------

 Click Browse SDC Service Models and search for the service to instantiate.

 The view show only service models in the DISTRIBUTED state.

 .. figure:: images/browse-service-models.png
    :align: center


 Select a service and click Deploy.

 A dialog box displays.

 Complete the fields indicated by the red star and click Confirm.

 .. figure:: images/create-service-instance-alacarte.png
    :align: center

 A status box appears that shows the ONAP SO instantiation progress
 as well as any messages associated with the process.

 .. figure:: images/create-service-instance-alacarte-success.png
    :align: center

 A Service object is created in ONAP.

 Click Close and next screen should appear.
 It will allow to declare VNF(s) and Network(s)
 that are part of the service model composition.

 .. figure:: images/create-service-instance-alacarte-VNF-network.png
    :align: center


 Instantiate a VNF
 -----------------

 From previous screen, it is possible to declare a VNF: click on
 "Add node instance" and select the VNF you want to instantiate in the list

 The  following screen should appear:

 .. figure:: images/create-vnf-instance-alacarte.png
    :align: center

 Complete the fields indicated by the red star and click Confirm.

 A VNF object will be declared in ONAP.

 Once, ONAP SO process is finished, click on close button.

 The following screen then should appear:


 .. figure:: images/create-service-instance-alacarte-after-vnf-instantiated.png
    :align: center


 Warning: a this step, no VNF instance (e.g. VM) is created on the Cloud Platform.

 Click on "i" blue button to obtain VNF instance display information.

 From this screen, it will be possible to get:

 - the service instance id value
 - the VNF Type value

 Those information will be necessary for the "SDNC preload" step
 to instantiate the VF module

 Close that screen


 Instantiate VF Module
 ---------------------

 It is now possible to declare a VF Module: click on
 "Add VF-Module" and select the VF-module you want to instantiate in the list

 The  following screen should appear:

 .. figure:: images/create-vfmodule-instance-alacarte.png
    :align: center

 From this screen, it will be possible to get:

 - "Model Name" value

 At this step, with this "A-La-Carte" method, it is necessary to declare
 some information in ONAP SDNC.

 SDNC needs to be aware about the VNF before trying to use ONAP SO
 to instantiate the VF-module.

 This group of data is usually called "SDNC preload" and will contain:

 - vf-module instance Name
 - vnf instance Name
 - service instance id
 - the list of vnf parameters with values, when not using the default values

 .. note::
    Get all the required vnf-parameters values as listed in HEAT package and populate all the key-values in an example SDNC preload curl command to run

 Some of the vnf-parameters in SDNC preload are related to openstack.
 Follow the below steps on openstack to get the values and update those values in SDNC preload template accordingly.

 - download the image from cloud images (ubuntu-14.04 as per HEAT env) and create an image
 - create the flavor with m1.medium (suggested as per HEAT env)
 - create OAM_NETWORK ID  & OAM_SUBNET ID (use subnet range from base_vfw.env file)
 - execute openstack security group rule to open all ports for onap

 Here is an example of SDNC preload for VNF, using "curl" tool
 to push those data using SDNC Rest API:

 ::

     curl -k -X POST \
     https://sdnc.api.simpledemo.onap.org:30267/restconf/operations/VNF-API:preload-vnf-topology-operation \

     -d '{
         "input": {
             "request-information": {
                 "notification-url": "onap.org",

                 "request-action": "PreloadVNFRequest",
                 "request-id": "test"
             },
             "sdnc-request-header": {
                 "svc-action": "reserve",
                 "svc-notification-url": "http:\/\/onap.org:8080\/adapters\/rest\/SDNCNotify",

             },
             "vnf-topology-information": {
                 "vnf-assignments": {
                     "availability-zones": [],
                     "vnf-networks": [],
                     "vnf-vms": []
                 },
                 "vnf-parameters": [
                     {
                         "vnf-parameter-name": "oam_net_id",
                         "vnf-parameter-value": "oam_network_tXWW"
                     }
                 ],
                 "vnf-topology-identifier": {
                     "generic-vnf-name": "my-vnf-instance-01",
                     "generic-vnf-type": "Service-model-with-VNF-and-Virtual-Link/FreeRadius_VF 0",
                     "service-type": "09f9ffad-1069-43fa-97e8-da7b9a439601",

                     "vnf-type": "FreeradiusVf..base_freeRadius..module-0"
                 }
             }
         }
     }'


 Data mapping between ONAP SDNC terminology and ONAP SO

 - "generic-vnf-name" value must be equal to the VNF instance name value
   (see VNF instance detail screen)
 - "generic-vnf-type" value must be equal to VNF Type value
   (see VNF instance detail screen)
 - "service-type" value must be equal to the service instance id value
   (see VNF instance detail screen)
 - "vnf-name" value must be equal to the VF module instance name value
 - "vnf-type" value must be equal to the "Model Name" value
   (see create VF module screen)


 If there is a need for an instance specific value
 of a VNF parameter (for example : an OAM network id value,
 specific to this VNF instance),
 the "vnf-parameters" must be completed with a list of name/value.

 Once the "SDNC preload" is completed, send it to SDNC using any Rest API Tool.

 Then, continue on VID and complete the fields indicated by the red star
 and click "Confirm".

 Warning : be very careful to use exactly the same VF module instance name
 on this screen and in the "SDNC preload"

 Wait for success and close the popup screen.

 The following screen should appear:

 .. figure:: images/create-service-instance-alacarte-after-vfmodule-instantiated.png
    :align: center

 At that point, the VNF is now instantiated in the cloud platform.


 Instantiate Network
 -------------------

 Instantiating a network is quite similar to vf-module instantiation
 (there is also the need for a "SDNC preload")

 Click on "Add Network" and select the Network you want
 to instantiate in the list

 The  following screen should appear:

 .. figure:: images/create-network-instance-alacarte.png
    :align: center


 Prepare the "SDNC preload" with:

 - "network-role": provide any value,
 - "network-technology": use "neutron" as this example will instantiate
   a network using openstack neutron application
 - "service-type": value must be equal to "Service Name"
   (=service model name) displayed on VID screen
 - "network-name": value must be equal to the desired network instance name,
 - "network-type": value must be equal to "Model Name""Generic NeutronNet"
   displayed on VID screen

 In addition:

 - in "provider-network-information" section, it is possible to indicate
   some network characteristics
 - it is possible to add a section about "subnets"

 Here after, an "SDNC preload" example that can be use for Network
 instantiation.

 in the cloud platform.

 Also, all those network information are available in ONAP AAI,
 under the terminology
 "l3-network", with the "neutron-network-id" and the "neutron-subnet-id"
 provided by
 the openstack platform.


 Deleting Network, VF module, VNF, Service
 -----------------------------------------

 To delete a service instance using VID, it is necessary to delete objects
 in the following sequence:

 - delete VF module(s)
 - delete VNF instance(s)
 - delete Network(s)
 - delete service instance

 To proceed those deletion, from VID Home screen

 - search for existing service instance
 - edit/view the service instance you want to delete
 - click on red button with white cross and confirm for each object

	-------------------

	Instantiating a network is quite similar to vf-module instantiation
	(there is also the need for a "SDNC preload")

	Click on "Add Network" and select the Network you want
	to instantiate in the list

	The following screen should appear:

	.. figure:: images/create-network-instance-alacarte.png
	:align: center


	Prepare the "SDNC preload" with:

	- "network-role": provide any value,
	- "network-technology": use "neutron" as this example will instantiate
	a network using openstack neutron application
	- "service-type": value must be equal to "Service Name"
	(=service model name) displayed on VID screen
	- "network-name": value must be equal to the desired network instance name,
	- "network-type": value must be equal to "Model Name""Generic NeutronNet"
	displayed on VID screen

	In addition:

	- in "provider-network-information" section, it is possible to indicate
	some network characteristics
	- it is possible to add a section about "subnets"

	Here after, an "SDNC preload" example that can be use for Network
	instantiation.

	}
	'

	Once the "SDNC preload" is completed, send it to SDNC using any Rest API Tool.

	Then, continue on VID and complete the fields indicated by the red star
	and click "Confirm".

	Warning : be very careful to use exactly the same network instance name
	on this screen and in the "SDNC preload"

	Wait for success and close the popup screen.

	The following screen should appear:

	.. figure:: images/create-network-instance-alacarte-after-instantiated.png
	:align: center

	At that point, the Network and subnets are now instantiated
	in the cloud platform.

	Also, all those network information are available in ONAP AAI,
	under the terminology
	"l3-network", with the "neutron-network-id" and the "neutron-subnet-id"
	provided by
	the openstack platform.


	Deleting Network, VF module, VNF, Service
	-----------------------------------------

	To delete a service instance using VID, it is necessary to delete objects
	in the following sequence:

	- delete VF module(s)
	- delete VNF instance(s)
	- delete Network(s)
	- delete service instance

	To proceed those deletion, from VID Home screen

	- search for existing service instance
	- edit/view the service instance you want to delete
	- click on red button with white cross and confirm for each object
