+vFirewall CNF Use Case
+----------------------
+
+Source files
+~~~~~~~~~~~~
+- Heat/Helm/CDS models: `vFW_CNF_CDS Model`_
+
+Description
+~~~~~~~~~~~
+This use case is a combination of `vFW CDS Dublin`_ and `vFW EDGEX K8S`_ use cases. The aim is to continue improving Kubernetes based Network Functions (a.k.a CNF) support in ONAP. Use case continues where `vFW EDGEX K8S`_ left and brings CDS support into picture like `vFW CDS Dublin`_ did for the old vFW Use case. Predecessor use case is also documented here `vFW EDGEX K8S In ONAP Wiki`_.
+
+In a higher level this use case brings only one improvement yet important one i.e. the ability to instantiate more than single CNF instance of same type (with same Helm package).
+
+Following improvements were made:
+
+- Changed vFW Kubernetes Helm charts to support overrides (previously mostly hardcode values)
+- Combined all models (Heat, Helm, CBA) in to same git repo and a creating single CSAR package `vFW_CNF_CDS Model`_
+- Compared to `vFW EDGEX K8S`_ use case **MACRO** workflow in SO is used instead of VNF workflow. (this is general requirement to utilize CDS as part of flow)
+- CDS is used to resolve instantion time parameters (Helm override)
+  - Ip addresses with IPAM
+  - Unique names for resources with ONAP naming service
+- Multicloud/k8s plugin changed to support identifiers of vf-module concept
+- CDS is used to create **multicloud/k8s profile** as part of instantiation flow (previously manual step)
+
+Use case does not contain Closed Loop part of the vFW demo.
+
+The vFW CNF Use Case
+~~~~~~~~~~~~~~~~~~~~
+The vFW CNF CDS use case shows how to instantiate multiple CNF instances similar way as VNFs bringing CNFs closer to first class citizens in ONAP.
+
+One of the biggest practical change compared to old demos (any onap demo) is that whole network function content (user provided content) is collected to one place and more importantly into git repository (`vFW_CNF_CDS Model`_) that provides version control (that is pretty important thing). That is very basic thing but unfortunately this is a common problem when running any ONAP demo and trying to find all content from many different git repos and even some files only in ONAP wiki.
+
+Demo git directory has also `Data Dictionary`_ file (CDS model time resource) included.
+
+Another founding idea from the start was to provide complete content in single CSAR available directly from that git repository. Not any revolutionary idea as that's the official package format ONAP supports and all content supposed to be in that same package for single service regardless of the models and closed loops and configurations etc.
+
+Following table describes all source models to which this demo is based on.

+
+Modeling CSAR/Helm
+..................
+
+The starting point for this demo was Helm package containing one Kubernetes application, see `vFW_Helm Model`_. In this demo we decided to follow SDC/SO vf-module concept same way as original vFW demo was splitted into multiple vf-modules instead of one (`vFW_NextGen`_). Same way we splitted Helm version of vFW into multiple Helm packages each matching one vf-module.
+
+Produced CSAR package has following MANIFEST file (csar/MANIFEST.json) having all Helm packages modeled as dummy Heat resources matching to vf-module concept (that is originated from Heat), so basically each Helm application is visible to ONAP as own vf-module. Actual Helm package is delivered as CLOUD_TECHNOLOGY_SPECIFIC_ARTIFACTS package through SDC and SO.
+
+CDS model (CBA package) is delivered as SDC supported own type CONTROLLER_BLUEPRINT_ARCHIVE.

+
+Multicloud/k8s
+..............
+
+K8s plugin was changed to support new way to identify k8s application and related multicloud/k8s profile.
+
+Changes done:
+
+- SDC distribution broker
+
+    **TODO: content here**
+
+- K8S plugin APIs changed to use VF Module Model Identifiers
+
+    Previously K8S plugin's used user given values in to identify object created/modified. Names were basing on VF-Module's "model-name"/"model-version" like "VfwLetsHopeLastOne..vfw..module-3" and "1". SO request has user_directives from where values was taken.
+
+    **VF Module Model Invariant ID** and **VF Module Model Version ID** is now used to identify artifact in SO request to Multicloud/k8s plugin. This does not require user to give extra parameters for the SO request as vf-module related parameters are there already by default. `MULTICLOUD-941`_
+    Note that API endpoints are not changed but only the semantics.
+
+    *Examples:*
+
+      Definition
+
+      ::
+
+          /api/multicloud-k8s/v1/v1/rb/definition/{VF Module Model Invariant ID}/{VF Module Model Version ID}/content
+
+
+      Profile creation API
+
+      ::
+
+          curl -i -d @create_rbprofile.json -X POST http://${K8S_NODE_IP}:30280/api/multicloud-k8s/v1/v1/rb/definition/{VF Module Model Invariant ID}/{VF Module Model Version ID}/profile
+          {    "rb-name": “{VF Module Model Invariant ID}",
+               "rb-version": "{VF Module Model Version ID}",
+               "profile-name": "p1",
+               "release-name": "r1",
+               "namespace": "testns1",
+               "kubernetes-version": "1.13.5"
+          }
+
+      Upload Profile content API
+
+      ::
+
+          curl -i --data-binary @profile.tar.gz -X POST http://${K8S_NODE_IP}:30280/api/multicloud-k8s/v1/v1/rb/definition/{VF Module Model Invariant ID}/{VF Module Model Version ID}/profile/p1/content
+
+- Default override support was added to plugin
+
+    **TODO: Some content here, maybe also picture**
+
+CDS Model (CBA)
+...............
+
+Creating CDS model was the core of the use case work and also the most difficult and time consuming part. There are many reasons for this e.g.
+
+- CDS documentation (even being new component) is inadequate or non-existent for service modeler user. One would need to be CDS developer to be able to do something with it.
+- CDS documentation what exists is non-versioned (in ONAP wiki when should be in git) so it's mostly impossible to know what features are for what release.
+- Our little experience of CDS (not CDS developers)
+
+At first the target was to keep CDS model as close as possible to `vFW_CNF_CDS Model`_ use case model and only add smallest possible changes to enable also k8s usage. That is still the target but in practice model deviated from the original one already and time pressure pushed us to not care about sync. Basically the end result could be possible much streamlined if wanted to be smallest possible to working only for K8S based network functions.
+
+As K8S application was splitted into multiple Helm packages to match vf-modules, CBA modeling follows the same and for each vf-module there's own template in CBA package.
+
+::
+
+    "artifacts" : {
+      "base_template-template" : {
+        "type" : "artifact-template-velocity",
+        "file" : "Templates/base_template-template.vtl"
+      },
+      "base_template-mapping" : {
+        "type" : "artifact-mapping-resource",
+        "file" : "Templates/base_template-mapping.json"
+      },
+      "vpkg-template" : {
+        "type" : "artifact-template-velocity",
+        "file" : "Templates/vpkg-template.vtl"
+      },
+      "vpkg-mapping" : {
+        "type" : "artifact-mapping-resource",
+        "file" : "Templates/vpkg-mapping.json"
+      },
+      "vfw-template" : {
+        "type" : "artifact-template-velocity",
+        "file" : "Templates/vfw-template.vtl"
+      },
+      "vfw-mapping" : {
+        "type" : "artifact-mapping-resource",
+        "file" : "Templates/vfw-mapping.json"
+      },
+      "vnf-template" : {
+        "type" : "artifact-template-velocity",
+        "file" : "Templates/vnf-template.vtl"
+      },
+      "vnf-mapping" : {
+        "type" : "artifact-mapping-resource",
+        "file" : "Templates/vnf-mapping.json"
+      },
+      "vsn-template" : {
+        "type" : "artifact-template-velocity",
+        "file" : "Templates/vsn-template.vtl"
+      },
+      "vsn-mapping" : {
+        "type" : "artifact-mapping-resource",
+        "file" : "Templates/vsn-mapping.json"
+      }
+    }
+
+Only **resource-assignment** workflow of the CBA model is utilized in this demo. If final CBA model contains also **config-deploy** workflow it's there just to keep parity with original vFW CBA (for VMs). Same applies for the related template *Templates/nf-params-template.vtl* and it's mapping file.
+
+The interesting part on CBA model is the **profile-upload** sub step of imperative workflow where Kotlin script is used to upload K8S profile into multicloud/k8s API.
+
+::
+
+    "profile-upload" : {
+      "type" : "component-script-executor",
+      "interfaces" : {
+        "ComponentScriptExecutor" : {
+          "operations" : {
+            "process" : {
+              "inputs" : {
+                "script-type" : "kotlin",
+                "script-class-reference" : "org.onap.ccsdk.cds.blueprintsprocessor.services.execution.scripts.K8sProfileUpload",
+                "dynamic-properties" : "*profile-upload-properties"
+              }
+            }
+          }
+        }
+      }
+    }
+
+Kotlin script expects that K8S profile package named like "k8s-rb-profile-name".tar.gz is present in CBA "Templates/k8s-profiles directory" where "k8s-rb-profile-name" is one of the CDS resolved parameters (user provides as input parameter).
+
+**TODO: something about the content and structure of profile package**
+
+As `Data Dictionary`_ is also included into demo git directory, re-modeling and making changes into model utilizing CDS model time / runtime is easier as used DD is also known.
+
+UAT
++++
+
+During testing of the use case **uat.yml** file was recorded according to `CDS UAT Testing`_ instructions. Generated uat.yml is stored within CBA package into **Tests** folder.
+
+Recorded uat.yml is an example run with example values (the values we used when demo was run) and can be used later to test CBA model in isolation (unit test style). This is very useful when changes are made to CBA model and those changes are needed to be tested fast. With uat.yml file only CDS is needed as all external interfaces are mocked. However, note that mocking is possible for REST interfaces only (e.g. Netconf is not supported).
+
+Another benefit of uat.yml is that it documents the runtime functionality of the CBA.
+
+To verify CBA with uat.yaml and CDS runtime do following:
+
+- Enable UAT testing for CDS runtime
+
+  ::
+
+      kubectl -n onap edit deployment onap-cds-cds-blueprints-processor
+
+      # add env variable for cds-blueprints-processor container:
+                name: spring_profiles_active
+                value: uat
+
+- Spy CBA functionality with UAT initial seed file
+
+::
+
+    curl -X POST -u ccsdkapps:ccsdkapps -F cba=@my_cba.zip -F uat=@input_uat.yaml http://<kube-node>:30499/api/v1/uat/spy
+
+where my_cba.zip is the original cba model and input_uat.yml is following in this use case:
+
+::
+
+    %YAML 1.1

+
+   vFW CNF CDS Use Case Runtime interactions.
+
+PART 1 - ONAP Installation
+--------------------------
+1-1 Deployment components
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In order to run the vFW_CNF_CDS use case, we need ONAP Frankfurt Release (or later) and at least following components:
+
+=======================================================   ===========
+ONAP Component name                                       Describtion
+-------------------------------------------------------   -----------
+AAI                                                       Required for Inventory Cloud Owner, Customer, Owning Entity, Service, Generic VNF, VF Module
+SDC                                                       VSP, VF and Service Modeling of the CNF
+DMAAP                                                     Distribution of the CSAR including CBA to all ONAP components
+SO                                                        Requires for Macro Orchestration using the generic building blocks
+CDS                                                       Resolution of cloud parameters including Helm override parameters for the CNF. Creation of the multicloud/k8s profile for CNF instantion.
+SDNC (needs to include netbox and Naming Generation mS)   Provides GENERIC-RESOURCE-API for cloud Instantiation orchestration via CDS.
+Policy                                                    Used to Store Naming Policy
+AAF                                                       Used for Authentication and Authorization of requests
+Portal                                                    Required to access SDC.
+MSB                                                       Exposes multicloud interfaces used by SO.
+Multicloud                                                K8S plugin part used to pass SO instanttion requests to external Kubernetes cloud region.
+Robot                                                     Optional. Can be used for running automated tasks, like provisioning cloud customer, cloud region, service subscription, etc ..
+Shared Cassandra DB                                       Used as a shared storage for ONAP components that rely on Cassandra DB, like AAI
+Shared Maria DB                                           Used as a shared storage for ONAP components that rely on Maria DB, like SDNC, and SO
+=======================================================   ===========
+
+1-2 Deployment
+~~~~~~~~~~~~~~
+
+In order to deploy such an instance, follow the `ONAP Deployment Guide`_
+
+As we can see from the guide, we can use an override file that helps us customize our ONAP deployment, without modifying the OOM Folder, so you can download this override file here, that includes the necessary components mentioned above.
+
+**override.yaml** file where enabled: true is set for each component needed in demo (by default all components are disabled).
+
+::
+
+  aai:
+    enabled: true
+  aaf:
+    enabled: true
+  cassandra:
+    enabled: true
+  cds:
+    enabled: true
+  contrib:
+    enabled: true
+  dmaap:
+    enabled: true
+  mariadb-galera:
+    enabled: true
+  msb:
+    enabled: true
+  multicloud:
+    enabled: true
+  policy:
+    enabled: true
+  portal:
+    enabled: true
+  robot:
+    enabled: true
+  sdc:
+    enabled: true
+  sdnc:
+    enabled: true
+  so:
+    enabled: true
+
+Then deploy ONAP with Helm with your override file.
+
+::
+
+    helm deploy onap local/onap --namespace onap -f ~/override.yaml
+
+In case redeployment needed `Helm Healer`_ could be a faster and convenient way to redeploy.
+
+::
+
+    helm-healer.sh -n onap -f ~/override.yaml -s /dockerdata-nfs --delete-all
+
+Or redeploy (clean re-deploy also data removed) just wanted components (Helm releases), cds in this example.
+
+::
+
+    helm-healer.sh -f ~/override.yaml -s /dockerdata-nfs/ -n onap -c onap-cds
+
+There are many instructions in ONAP wiki how to follow your deployment status and does it succeeded or not, mostly using Robot Health checks. One way we used is to skip the outermost Robot wrapper and use directly ete-k8s.sh to able to select checked components easily. Script is found from OOM git repository *oom/kubernetes/robot/ete-k8s.sh*.
+
+::
+
+    for comp in {aaf,aai,dmaap,msb,multicloud,policy,portal,sdc,sdnc,so}; do
+        if ! ./ete-k8s.sh onap health-$comp; then
+            failed=$failed,$comp
+        fi
+    done
+    if [ -n "$failed" ]; then
+        echo "These components failed: $failed"
+        false
+    else
+        echo "Healthcheck successful"
+    fi
+
+And check status of pods, deployments, jobs etc.
+
+::
+
+    kubectl -n onap get pods | grep -vie 'completed' -e 'running'
+    kubectl -n onap get deploy,sts,jobs
+
+
+1-3 Post Deployment
+~~~~~~~~~~~~~~~~~~~
+
+After completing the first part above, we should have a functional ONAP deployment for the Frankfurt Release.
+
+We will need to apply a few modifications to the deployed ONAP Frankfurt instance in order to run the use case.
+
+Postman collection setup
+........................
+
+In this demo we have on purpose created all manual ONAP preparation steps (which in real life are automated) by using Postman so it will be clear what exactly is needed. Some of the steps like AAI population is automated by Robot scripts in other ONAP demos (**./demo-k8s.sh onap init**) and Robot script could be used for many parts also in this demo. Later when this demo is fully automated we probably update also Robot scripts to support this demo.
+
+Postman collection is used also to trigger instantion using SO APIs.
+
+Following steps are needed to setup postman:
+
+- Import this postman collection zip
+
+  :download: `postman.zip`_
+
+- Extract the zip and import 2 postman cllection and environment files into Postman
+    - `vFW_CNF_CDS.postman_collection.json`
+    - `vFW_CNF_CDS.postman_environment.json`
+
+- For use case debugging purposes to get Kubernetes cluster external access to SO CatalogDB (GET operations only), modify SO CatalogDB service to NodePort instead of ClusterIP. You may also create separate own NodePort if you wish, but here we have just edited directly the service with kubectl. Note that the port number 30120 is used in postman collection.
+
+::
+
+    kubectl -n onap edit svc so-catalog-db-adapter
+         - .spec.type: ClusterIP
+         + .spec.type: NodePort
+         + .spec.ports[0].nodePort: 30120
+
+**Postman variables:**
+
+Most of the postman variables are automated by postman scripts and environment file provided, but there are few mandatory variables to fill by user.
+
+===================  ===================
+Variable             Description
+-------------------  -------------------
+k8s                  ONAP Kubernetes host
+sdnc_port            port of sdnc service for accessing MDSAL
+cds-service-name     name of service as defined in SDC
+cds-instance-name    name of instantiated service (if ending with -{num}, will be autoincremented for each instantiation request)
+===================  ===================
+
+You can get the sdnc_port value with
+
+::
+
+    kubectl -n onap get svc sdnc -o json | jq '.spec.ports[]|select(.port==8282).nodePort'
+
+
+**TODO: change variable names something else than cds-xxx**
+
+
+AAI
+...
+
+Some basic entries are needed in ONAP AAI. These entries are needed ones per onap installation and do not need to be repeated when running multiple demos based on same definitions.
+
+Create all these entries into AAI in this order. Postman collection provided in this demo can be used for creating each entry.
+
+**Postman -> Robot Init Stuff**
+
+- Create Customer
+- Create Owning-entity
+- Create Platform
+- Create Project
+- Create Line Of Business
+
+Corresponding GET operations in postman can be used to verify entries created. Postman collection also includes some code that tests/verifies some basic issues e.g. gives error if entry already exists.
+
+SO Cloud region configuration
+.............................
+
+SO database needs to (manually) modified for SO to know that this particular cloud region is to be handled by multicloud. Values we insert needs to obviously match to the ones we populated into AAI.
+
+The related code part in SO is here: `SO Cloud Region Selection`_
+It's possible improvement place in SO to rather get this information directly from AAI.
+
+::
+
+    kubectl -n onap exec onap-mariadb-galera-mariadb-galera-0 -it -- mysql -uroot -psecretpassword -D catalogdb
+        select * from cloud_sites;
+        insert into cloud_sites(ID, REGION_ID, IDENTITY_SERVICE_ID, CLOUD_VERSION, CLLI, ORCHESTRATOR) values("k8sregionfour", "k8sregionfour", "DEFAULT_KEYSTONE", "2.5", "clli2", "multicloud");
+        select * from cloud_sites;
+        exit
+
+SO BPMN endpoint fix for VNF adapter requests (v1 -> v2)
+........................................................
+
+SO Openstack adapter needs to be updated to use newer version. Here is also possible improvement area in SO. Openstack adapter is confusing in context of this use case as VIM is not Openstack but Kubernetes cloud region. In this use case we did not used Openstack at all.
+
+::
+
+    kubectl -n onap edit configmap onap-so-so-bpmn-infra-app-configmap
+      - .data."override.yaml".mso.adapters.vnf.rest.endpoint: http://so-openstack-adapter.onap:8087/services/rest/v1/vnfs
+      + .data."override.yaml".mso.adapters.vnf.rest.endpoint: http://so-openstack-adapter.onap:8087/services/rest/v2/vnfs
+      kubectl -n onap delete pod -l app=so-bpmn-infra
+
+Naming Policy
+.............
+
+Naming policy is needed to generate unique names for all instance time resources that are wanted to be modeled in the way naming policy is used. Those are normally VNF, VNFC and VF-module names, network names etc. Naming is general ONAP feature and not limited to this use case.
+
+The override.yaml file above has an option **"preload=true"**, that will tell the POLICY component to run the push_policies.sh script as the POLICY PAP pod starts up, which will in turn create the Naming Policy and push it.
+
+To check that the naming policy is created and pushed OK, we can run the commands below.
+
+::
+
+  # goto inside of a POD e.g. pap here
+  kubectl -n onap exec -it $(kubectl -n onap  get pods -l app=pap --no-headers | cut -d" " -f1) bash
+
+  bash-4.4$ curl -k --silent -X POST \
+  --header 'Content-Type: application/json' \
+  --header 'ClientAuth: cHl0aG9uOnRlc3Q=' \
+  --header 'Authoment: TEST' \
+  -d '{ "policyName": "SDNC_Policy.Config_MS_ONAP_VNF_NAMING_TIMESTAMP.1.xml"}' \

+
+Network Naming mS
++++++++++++++++++
+
+There's a strange feature or bug in naming service still at ONAP Frankfurt and following hack needs to be done to make it work.
+
+::
+
+  # Go into naming service database pod
+  kubectl -n onap exec -it $(kubectl -n onap get pods --no-headers | grep onap-sdnc-nengdb-0 | cut -d" " -f1) bash
+
+  # Delete entries from EXTERNAL_INTERFACE table
+  mysql -unenguser -pnenguser123 nengdb -e 'delete from EXTERNAL_INTERFACE;'
+
+
+PART 2 - Installation of managed Kubernetes cluster
+---------------------------------------------------
+
+In this demo the target cloud region is a Kubernetes cluster of your choice basically just like with Openstack. ONAP platform is a bit too much hard wired to Openstack and it's visible in many demos.
+
+2-1 Installation of Managed Kubernetes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In this demo we use Kubernetes deployment used by ONAP multicloud/k8s team to test their plugin features see `KUD readthedocs`_. There's also some outdated instructions in ONAP wiki `KUD in Wiki`_.
+
+KUD deployment is fully automated and also used in ONAP's CI/CD to automatically verify all `Multicloud k8s gerrit`_ commits (see `KUD Jenkins ci/cd verification`_) and that's quite good (and rare) level of automated integration testing in ONAP. KUD deployemnt is used as it's installation is automated and it also includes bunch of Kubernetes plugins used to tests various k8s plugin features. In addition to deployement, KUD repository also contains test scripts to automatically test multicloud/k8s plugin features. Those scripts are run in CI/CD.
+
+See `KUD subproject in github`_ for a list of additional plugins this Kubernetes deployment has. In this demo the tested CNF is dependent on following plugins:
+
+- ovn4nfv
+- Multus
+- Virtlet
+
+Follow instructions in `KUD readthedocs`_ and install target Kubernetes cluster in your favorite machine(s), simplest being just one machine. Your cluster nodes(s) needs to be accessible from ONAP Kuberenetes nodes.
+
+2-2 Cloud Registration
+~~~~~~~~~~~~~~~~~~~~~~
+
+Managed Kubernetes cluster is registered here into ONAP as one cloud region. This obviously is done just one time for this particular cloud. Cloud registration information is kept in AAI.
+
+Postman collection have folder/entry for each step. Execute in this order.
+
+**Postman -> AAI -> Create**
+
+- Create Complex
+- Create Cloud Region
+- Create Complex-Cloud Region Relationship
+- Create Service
+- Create Service Subscription
+- Create Cloud Tenant
+- Create Availability Zone
+
+**Postman -> Multicloud**
+
+- Upload Connectivity Info  **TODO: where to get kubeconfig file?**
+
+
+PART 3 - Execution of the Use Case
+----------------------------------
+
+This part contains all the steps to run the use case by using ONAP GUIs and Postman.
+
+Following picture describes the overall sequential flow of the use case.
+
+.. figure:: files/vFW_CNF_CDS/vFW_CNF_CDS_Flow.png

+
+   vFW CNF CDS Use Case sequence flow.
+
+3-1 Onboarding
+~~~~~~~~~~~~~~
+
+Creating CSAR
+.............
+
+Whole content of this use case is stored into single git repository and ONAP user content package CSAR package can be created with provided Makefile.
+
+Complete content can be packaged to single CSAR file in following way:
+(Note: requires Helm installed)
+
+::
+
+  git clone https://gerrit.onap.org/r/demo
+  cd heat/vFW_CNF_CDS/templates
+  make
+
+The output looks like:

+3-2 CNF Instantiation
+~~~~~~~~~~~~~~~~~~~~~
+
+This is the whole beef of the use case and furthermore the core of it is that we can instantiate any amount of instances of the same CNF each running and working completely of their own. Very basic functionality in VM (VNF) side but for Kubernetes and ONAP integration this is the first milestone towards other normal use cases familiar for VNFs.
+
+Use again Postman to trigger instantion from SO interface. Postman collection is automated to populate needed parameters when queries are run in correct order. If you did not already run following 2 queries after distribution (to verify distribution), run those now:
+
+- **Postman -> SDC/SO -> SDC Catalog Service**
+- **Postman -> SDC/SO -> SO Catalog DB Service xNFs**
+
+Now actual instantiation can be triggered with:
+
+**Postman -> SDC/SO -> SO Self-Serve Service Assign & Activate**
+
+Follow progress with SO's GET request:
+
+**Postman -> SDC/SO -> SO Infra Active Requests**
+
+The successful reply payload in that query should start like this:
+
+::
+
+    {
+      "clientRequestId": null,
+      "action": "createInstance",
+      "requestStatus": "COMPLETED",
+      "statusMessage": "Failed to create self-serve assignment for vf-module with vf-module-id=b70112fd-f6b2-44fe-a55c-6928d61843bf with error: Encountered error from self-serve-generate-name with error: Error from NameGenerationNode Assign",
+      "rollbackStatusMessage": null,
+      "flowStatus": "Execution of UnassignVfModuleBB has completed successfully, next invoking UnassignVfModuleBB (Execution Path progress: BBs completed = 1; BBs remaining = 4).",
+      "retryStatusMessage": null,
+    ...
+
+**TODO: fix COMPLETED payload**
+
+Progress can be followed also with `SO Monitoring`_.
+
+Second instance Instantion
+..........................
+
+To finally verify that all the work done within this demo, it should be possible to instantiate second vFW instance successfully.
+
+Trigger again:
+
+**Postman -> SDC/SO -> SO Self-Serve Service Assign & Activate**
+
+**TODO: update to seconf call in postman**

+Component Logs From The Execution
+.................................
+
+All logs from the use case execution are here:
+
+  :download: `logs.zip`_
+
+- `so-bpmn-infra_so-bpmn-infra_debug.log`
+- SO openstack adapter
+- `sdnc_sdnc_karaf.log`
+
+  From karaf.log all requests (payloads) to CDS can be found by searching following string:
+
+  ``'Sending request below to url http://cds-blueprints-processor-http:8080/api/v1/execution-service/process'``
+
+- `cds-blueprints-processor_cds-blueprints-processor_POD_LOG.log`
+- `multicloud-k8s_multicloud-k8s_POD_LOG.log`
+- network naming
+
+Debug log
++++++++++
+
+In case more detailed logging is needed, here's instructions how to setup DEBUG logging for few components.
+
+- SDNC
+
+  ::
+
+    kubectl -n onap exec -it onap-sdnc-sdnc-0 -c sdnc /opt/opendaylight/bin/client log:set DEBUG
+
+
+- CDS Blueprint Processor
+
+  ::
+
+    # Edit configmap
+    kubectl -n onap edit configmap onap-cds-cds-blueprints-processor-configmap
+
+    # Edit logback.xml content change root logger level from info to debug.
+    <root level="debug">
+        <appender-ref ref="STDOUT"/>
+    </root>
+
+    # Delete the POd to make changes effective
+    kubectl -n onap delete pod $(kubectl -n onap get pod -l app=cds-blueprints-processor --no-headers | cut -d" " -f1)
+
+PART 4 - Summary and Future improvements needed
+-----------------------------------------------
+
+This use case made CNFs onboarding and instantiation a little bit easier and closer to "normal" VNF way. Also CDS resource resolution capabilities were taken into use (compared to earlier demos) together with SO's MACRO workflow.
+
+CNF application in vFW (Helm charts) were divided to multiple Helm charts comply with vf-module structure of a Heat based VNF.
+
+Future development areas for this use case and in general for CNF support could be:
+
+- Automate manual initialization steps in to Robot init. Now all was done with Postman or manual step on command line.
+- Automate use case in ONAP daily CI
+- Include Closed Loop part of the vFW demo.
+- Use multicloud/k8S API v2. Also consider profile concept future.
+- Sync CDS model with `vFW_CNF_CDS Model`_ use case i.e. try to keep only single model regardless of xNF being Openstack or Kubernetes based.
+- TOSCA based service and xNF models instead of dummy Heat wrapper. Won't work directly with current vf-module oriented SO workflows.
+- vFW service with Openstack VNF and Kubernetes CNF
+
+
+Multiple lower level bugs/issues were also found during use case development
+
+- Distribution of Helm package directly from CSAR package `SDC-2776`_
