Creating a Service Instance

In this tutorial we show how to take a service design that has been distributed and create a running instance of the service. 

To simplify this we are going to use scripts (with some selenium robot scripts) to create the design, pre-load customer and network information, and orchestrate parts of the virtual firewall closed loop example.  The following steps assume that you have completed and understand basic concepts from the setting up the platform and using the portal tutorials. 

Let's start by finding the IP Address of vm1-robot in the Rackspace list of servers.  Use this vm1-robot IP address, your Rackspace private key, and the PuTTY client to login to vm1-robot as root.

Note: The current default LCP Region is IAD - to use DFW switch the example zip in the last section - currently though we have hardcoding that must be fixed: 

...

osx$ ssh-add onap_rsa

osx$ ssh root@104.130.170.232

Run Robot demo.sh init

At the command prompt type

...

root@vm1-robot:~# cd /opt

root@vm1-robot:/opt# ./demo.sh init

Wait for all steps to complete (will take 60-120 sec) as shown below

If you want to see the details of what ran, you can open report.html in a browser. (located within openecompete_container docker container)

Deploy Service Instance in VID

From the ONAP portal, login to the VID application using demo user, browse to locate the demo SDC Service Models, and Deploy an instance of the service you created - not the pre-populated demoVFW.

Image Removed

(Note: deploy your "service" above - not demoVFW or demoVLB - these 2 are leftover pre-population artifacts of the init script and will be removed)

Fill in the information (Instance Name=DemoInstance, Demonstration, vFW) for a Service Instance as shown below and press Confirm.

Image Removed

Wait for a response and close the window

Image Removed

You should now see a service instance displayed.

Image Removed

Add a Virtual Network Function under the Service Instance in VID

Add a VNF using the drop down button, complete, and enter the following information.   The tenant and LCP region drop down choices may be different for your Rackspace account.  Both IAD and DFW support heat templates.

Wait for and close the response window.

Run Robot demo.sh preload of DemoModule

Return to the PuTTY/ssh window and type the command to load VNF configuration information

DO NOT Navigate from the Deploy page before adding the VF Module below - or you will need to search for it - then hit edit

     
    ./demo.sh preload <vnf_name> <module_name>
    example
    ./demo.sh preload DemoVNF DemoModule

Wait for the results as shown below

For any error/debug logs looks into 

/opt/eteshare/logs/demo/PreloadDemo/output.xml

Add a VF Module in VID

Add a VF Module using the drop down button.

Image Removed

Fill in information for the VF module (service name = Service) and confirm.

Image Removed

Watch VF VM stack creation

Watch as the 3 VMs for the VF start to come up on Rackspace (dialog is still up)

Note: Openstack users with RegionOne may see failures here. Looks into the below ticker to update MSO docker container /shared/mso-docker.json file with RegionOne settings. For logs use

TODO:

20171120: Brian Freeman has commented on R1 changes - need to verify these in a live system before posting here

VNF preload is now part of VID in a checkbox - so we don't require the sdnc rest call as part of demo.sh preload

Robot in OOM is run in oom/kubernetes/robot now

Preload Flow

see overall Tutorial: Verifying and Observing a deployed Service Instance#vFirewallFlow

demo.sh calls runTags.sh in the docker container in robot - which runs the robot test framework scripts starting with PreLoad VNF in demo.robot

Preload VNF
    Preload User Model   ${VNF_NAME}   ${MODULE_NAME}

which calls demo_preload.robot (although it screen scrapes the Service ID previously from VID - in this call it does a rest call to VID to package up the vm modules list) and calls SDNC preload with these (the diagram needs a 25-2 for robot to VID as well for this sub-step)

Preload User Model
    Login To VID GUI
    ${vf_modules}=   Get Module Names from VID    ${invariantUUID}
    Preload Vnf    ${service_instance_id}   ${vnf_name}   ${vnf_type}   ${vf_module_name}    ${vf_modules}    ${service}    demo

which calls sdngc_interface.robot (logs in and posts to sdnc/mobility/addVnfProfile)

Preload Vnf Profile
    Login To SDNGC Admin GUI
    Go To    ${SDNGC_ADMIN_VNF_PROFILE_URL}
    Click Button    xpath=//button[@data-target='#add_vnf_profile']
    Click Button    xpath=//button[contains(.,'Submit')]

which calls the post form

<form name="addForm" role="form" action="/mobility/addVnfProfile" method="POST">

http://sdnc:8843/mobility/getVnfProfile

which runs a backend DB insert operation on SDNC (calling the DB directly here is likely not advised, also there is no parameter checking on the resultant SQL, we should also be using an ORM framework)

/sdnc-oam/admportal/mobility.js

router.post('/addVnfNetwork', csp.checkAuth, function(req,res){
 var sql = "INSERT INTO VNF_NETWORKS (vnf_type,network_role) VALUES ("
 + "'" + req.body.nf_vnf_type + "'," + "'" + req.body.nf_network_role + "')";
 tasks.push( function(callback) { dbRoutes.executeSQL(sql,req,res,callback); } );

Add a VF Module in VID

Option 1: REST call to MSO

POST to http://{{mso_ip}}:8080/ecomp/mso/infra/serviceInstances/v2/<id>/vnfs/<id>/vfModules - see UCA-20 OSS JAX-RS 2 Client

Option 2: VID GUI

Add a VF Module using the drop down button.

Create VF Module - polling hangs - vFW VMs are created though

Eventually you will see a (red-herring) poll timeout - we need to adjust the wait time and # of retries here - anyway the 3 VM's are up (with pings but not necessarily with 200 health checks on the processes)

Select close, and later cancel (for now) - as the VMs are actually up

Handle outdated vFW (201702xx) zip causing Traffic Generation not to start

Fix: Use the 1.0.0 template in Nexus - or the updated one on this wiki

1)      The vFW zip attached to the onap.org wiki that we were using will not work with 1.0.0-SNAPSHOT or 1.0.0 (disabled/replacing it) – we are using the official yaml now from 1.0.0 - this fixes the userdata bootstrap script on the PGN instance – where nexus pulls of TG scripts was failing (why the demo did not work in the past) – we now use (with modified ssh key, ips and networks)

Heat template:

https://nexus.onap.org/content/sites/raw/org.openecomp.demo/heat/vFW/1.0.0/

Scripts to verify on the pgn VM:

After this we were able to run ./demo.sh appc – to start the TG

Issue:

We are currently having issues with the traffic generator - both starting the stream and also actually sshing to the VM (looks like the ssh key in the env is not picked up)

Fix: the repo URL in the vFW zip has changed to

TODO: 20181023 during the Academic Conference : the SDNC preload checkbox does not actually run the preload robot script -  - still need a manual preload via the rest call in Vetted vFirewall Demo - Full draft how-to for F2F and ReadTheDocs - it just tells SO to pull in data from SDNC

Install the vFWCL first because it has the network

to do repeated instantiations - adjust the network values in the preload-vnf-topology-operation rest call - being automated in casablanca - 92,96, put the right service-type (Service Instance ID - top right in the gui)
