Copyright © 2017-2020 Aarna Networks, Inc. + +vFWCL Design Tutorial +##################### + +The instructions in this section will enable you to design the vFW Control Loop. The prerequisite for this tutorial is that the +vFW_service design/deployment/instantiation should be completed. + +Control Loop Flow +================= + +This section describes the vFW control loop flow and the modules involved. Following is the list of modules +that are involved in designing and deploying the vFW CL + + 1) SDC: The first step of the procedure is to distribute the DCAE (TCA microservice) blueprint. That is done through ONAP SDC. + 2) CLAMP: This is a tool for designing the policy and configuring the TCA threshold. CLAMP, along with DCAE, can also be used + to manage the lifecycle of CLs + 3) DCAE (platform and micro services): Multiple components of the DCAE module get involved in the overall lifecycle of the CL. + 4) TCA: The CDAP threshold controlling application is a DCAE microservice. + 5) ONAP Policy engine: The output of DCAE is sent to the Policy engine as an input event. We will use the DROOLS Policy engine. + 6) APPC : The last hop in the CL, which takes the config action on the vPG on the output of the Policy engine. + +Distribute DCAE blueprints +========================== + +In order to distribute the DCAE microservice blueprints we need to create a dummy service. The DCAE blueprint will be added as an artifact +to the VF inside the service during service composition time. + +Follow the below steps to upload the blueprint for the TCA (Threshold Checking Application) DCAE microservice and Distribute the service to the CLAMP + +The following screenshot of the setup shows where “dcae_service” has been created and is in the composition phase. + +.. note:: + The service name should not contain any spaces. The DCAE policy fails to fetch the service from PDP if the name has a space. + For example ‘dcae1’ will work and ‘dcae 1’ will not. + +1. Login as DESIGNER (cs0008) and create the service, checkin and certify + +|image16| + +2. Add any VNF (ex: vfw_pg) that was already created during the SDC design phase + +In the composition canvas drag and drop a resource of type VF from the abstract section in the Elements section (left hand side panel) + +|image15| + +3. Download the required DCAE MS blueprint to be attached to the service + +Use the sample TCA blueprint located here: +https://git.onap.org/dcaegen2/platform/blueprints/tree/blueprints/k8s-tcagen2-clampnode.yaml + +.. note:: + * Check if the version of the plugin used in the blueprint is different from existing, then update the blueprint import to match + * To check the version run this: `cfy plugins list | grep k8splugin` + +4. Now upload the Control Loop Artifact. The procedure to upload the artifact is + + * Click on the VF, as in the picture above the ‘vsp_pg 0’ is selected + * Click on ‘DEPLOYMENT ARTIFACTS’ and then click on “Add Artifact” + + |image5| + + * Fill the details and in the type select DCAE_INVENTORY_BLUEPRINT, then click on Done as in the picture shown below + + |image13| + +5. After uploading the DCAE artifact to the SDC Service, attach the policy model to the Service. From the left drop down, +select TCA policy under Policies, and click on the Add policy + +|image1| + +6. Click on Checkin on top right corner then click OK + +|image12| + +7. Search and select the same service from CATALOG and click on Certify on top right corner + +|image14| + +8. Click Distribute to distribute the service, then click on Distribution in the left hand side panel and monitor until +the distribution is complete. We should see artifacts deployed in CLAMP and Policy engine, as can be seen in the picture below + +|image19| + +At this point we can open the CLAMP GUI and verify that the DCAE microservice design template is in place + +DCAE MS design in CLAMP +======================= + +CLAMP is a GUI tool which enables the users to design the policies, distribute them to the DROOLS engine and eventually deploy +the DCAE microservices. In this section we are going to design, distribute and deploy the BRMS (DROOLS) and TCA policy. + +Clamp uses AAF to authenticate the user and get the different permissions. In order to access the CLAMP GUI we will need to add the certificate. + +1. Add the necessary certificates in the browser + +The default certificate can be found here: https://gerrit.onap.org/r/gitweb?p=clamp.git;a=blob;f=src/main/resources/clds/aaf/org.onap.clamp.p12;h=268aa1a3ce56e01448f8043cc0b05b5fceb5a47d;hb=HEAD + +The password is: "China in the Spring" +The certificate must be loaded into your favorite browser before trying to load the CLAMP UI. + +Ex: In case of Firefox browser, below is the procedure on how to add the certificate + +Open firefox browser and go to Preferences and search for Certificate Manager and Select “View Certificates“ button. +This will open the following dialog to import certificate files from Your certificates menu. + +You need to go in options->Privacy & Security-> Scroll down to Certificates options a View Certificates Button +and then Your certificates Tab -> Then Import button + +|image6| + +2. After the certificate is added, the CLAMP GUI can be accessed at: +`https://<host_IP>:30258` (host_IP is the node IP where CLAMP is running) + +3. Before designing the policy we need to undeploy the default tca policy. +To undeploy default policy execute the below commands on control node + +.. code-block:: + + > kubectl get deployments -n onap | grep "dep-dcae-tca-analytics\|dcaegen2-analytics-tca" | awk '{print $1}' | + xargs kubectl delete deployments -n onap + > kubectl get svc -n onap | grep "dcae-tca-analytics\|dcaegen2-analytics-tca" | awk '{print $1}' | + xargs kubectl delete svc -n onap + To Verify there are no dcae-analytics POD, run the below command + > kubectl get pods -n onap | grep 'analytics' + +4. If the service has been distributed correctly, following is how the service design templates +listed in the Loop Templates as below + +|image7| + +Available Policy Models + +|image10| + +5.
