Metaswitch has an open sourced vIMS solution known as Clearwater that is a useful demonstration of features in ONAP for onboarding new VNFs. 

The team at Metaswitch has created ONAP compliant HEAT templates and we would like to thank Metaswitch for providing them for use both in this tutorial and for people that would like to spin up Clearwater vIMS in their environments.

Its a fairly complex VNF with 7 server types with each server having a primary and secondary pair. This tutorial will show the steps for onboarding and instantiating the vIMS VNF onto ONAP. It will also show how to use the Clearwater test suite to confirm the installation. No customizations have been done so its not a production ready installation but an example of the steps to onboard and instantiate a more complex VNF.

Image Added

The HEAT templates used for this tutorital have not be optimized for closed loop control etc since all interfaces on the virtual machines are on the public IP side. Over time we will likely modify the HEAT template to add an internal ONAP OA&M LAN and add a tutorial to show closed loop control  with DCAE, Policy, APPC to perhaps restart one of the servers.

The An example HEAT template plus manifest zip file for uploading to SDC is in gerrit under the demo project (fill in full path) Metaswitch's github (https://github.com/Metaswitch/clearwater-onap) .

You will need to modify the nested yaml files.

Unzip the file and change the lines that refernence "server" to be the component name "_server" in two places.

So for bono.yaml change sever to bono_sever in both the resource and in the output.

bono.yaml: bono_server:

bono.yaml: value: { get_attr: [ bono_server, accessIPv4 ] }
dns.yaml: dns_server:
dns.yaml: value: { get_attr: [ dns_server, accessIPv4 ] }
ellis.yaml: ellis_server:
ellis.yaml: value: { get_attr: [ ellis_server, accessIPv4 ] }
homer.yaml: homer_server:
homer.yaml: value: { get_attr: [ homer_server, accessIPv4 ] }
homestead.yaml: homestead_server:
homestead.yaml: value: { get_attr: [ homestead_server, accessIPv4 ] }
ralf.yaml: ralf_server:
ralf.yaml: value: { get_attr: [ ralf_server, accessIPv4 ] }
sprout.yaml: sprout_server:
sprout.yaml: value: { get_attr: [ sprout_server, accessIPv4 ] }

Also remove COPYING from the zip file since that isnt in the manifest.json.

Recreate the zip with a command like: zip clearwater.20180606.zip *

       1. this is a text only attribute that is used for tracking what project owned a VNF/Service. Its not used by ONAP.
    5. Click Create
       
       
       
       
42. As when we created our virtual function, the sidebar links were greyed; now that the service has been created, they're active. Click on the icon link, and select an icon for the service.
43. Next, click on "Composition". This is the step at which we actually "design" the service we'll be distributing. Initially, the "Composition" page shows an empty canvas and a couple of default network elements. Enter IMS in the search window . 
44. Now we can see our vIMS VF in the sidebar. Drag the VF out of the sidebar and drop it onto the canvas.
    
    
    
45. You have now created a new service consisting of the single virtual function. Before it can be distributed for use, though, the service must be tested and approved. Click "Submit for testing" and enter a message in the dialog which appears. Click "Save".
46. You'll be returned to the SDC Home screen, and an alert showing that the new service has been successfully submitted for testing will appear. Note that both our virtual function and our new service now appear on the SDC Home screen; the service shows "v0.1" and a status of "Ready for testing".
47. jm008: This completes our Designer's involvement in the workflow, and the service now goes to the Tester for testing and approval. Log out and log back in as jm0007.

    4. Click on the service artifact to access its details and then click the "Approve" button above the form
       
    5. Enter text for the message
49. op0001: The Governor's part in the workflow is now complete, and it only remains for a user in the "Ops" role to actually distribute the service. Log out, and log in again as op0001. Access the SDC Home page, which now shows the "tutorial service" with a status of "Distribution Approved".
    
    1. select the vIMS Service
    2. click on Distribute
    3. Enter text
