Installation ^^^^^^^^^^^^ Follow the OOM installation instructions at http://onap.readthedocs.io/en/latest/submodules/oom.git/docs/index.html Overview of the running system ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Upon initialization, you should see the following pods, one instance for each Policy component: PAP, PDP-X, BRMSGW, PDP-D, policydb, and nexus. Note the "-0" suffix for PDP-X and PDP-D components, which will be increased as they are scaled out to improve runtime performance and reliability. .. code-block:: bash :caption: verify pods kubectl get pods --all-namespaces -o=wid onap dev-brmsgw-5dbc4c8dc4-llk5s 1/1 Running 0 18m 10.42.120.43 k8sx onap dev-drools-0 1/1 Running 0 18m 10.42.60.27 k8sx onap dev-nexus-7d96568f5f-qp5td 1/1 Running 0 18m 10.42.172.8 k8sx onap dev-pap-8587696769-vwj6k 2/2 Running 0 18m 10.42.19.137 k8sx onap dev-pdp-0 2/2 Running 0 18m 10.42.144.218 k8sx onap dev-policydb-587d55bdff-4f5dz 1/1 Running 0 18m 10.42.12.242 k8sx You will also see a service for every component: .. code-block:: bash :caption: verify services kubectl get services --all-namespaces onap brmsgw NodePort 10.43.209.173 9989:30216/TCP 24m onap drools NodePort 10.43.27.92 6969:30217/TCP,9696:30221/TCP 24m onap nexus NodePort 10.43.19.171 8081:30236/TCP 24m onap pap NodePort 10.43.9.166 8443:30219/TCP,9091:30218/TCP 24m onap pdp ClusterIP None 8081/TCP 24m onap policydb ClusterIP None 3306/TCP 24m Config and Decision policy requests will be distributed across PDP-Xs through the *pdp* service. PDP-X clients (such as DCAE) should configure their URLs to go through the *pdp* service. Their requests will be distributed across the available PDP-X replicas. The PDP-Xs can be also accessed individually (dev-pdp-0, or dev-pdp-x if scaled out), but is preferable for PDP-X external clients to interface through the service. PDP-Ds are also accessible on a group fashion by using the service IP, but DMaaP is the main means of communication with other ONAP components. Healthchecks ^^^^^^^^^^^^ Verify that the policy healthcheck passes by the robot framework: .. code-block:: bash :caption: robot healthcheck ~/oom/kubernetes/robot/ete-k8s.sh onap health 2> /dev/null | grep PASS .. Basic Policy Health Check | PASS | .. A policy healthcheck (with more detailed output) can be done directly by invoking the drools service in the policy VM. .. code-block:: none :caption: PDP-D service (more detailed) healthcheck # Using default credentials for the healtcheck service. # To change the default username and passwords for this service, # please modify configuration pre-installation at: # oom/kubernetes/policy/charts/drools/resources/config/opt/policy/config/drools/keys/feature-healthcheck.conf curl --silent --user 'demo@people.osaaf.org:demo123456!' -X GET http://localhost:30217/healthcheck | python -m json.tool { "details": [ { "code": 200, "healthy": true, "message": "alive", "name": "PDP-D", "url": "self" }, { "code": 200, "healthy": true, "message": "", "name": "PAP", "url": "http://pap:9091/pap/test" }, { "code": 200, "healthy": true, "message": "", "name": "PDP", "url": "http://pdp:8081/pdp/test" } ], "healthy": true } PDP-X Active/Active Pool ^^^^^^^^^^^^^^^^^^^^^^^^ The policy engine UI (console container in the pap pod) can be used to check that the PAP and the PDP-Xs are synchronized. The console URL is accessible at ``http://:30219/onap/login.htm``. Select the *PDP* menu entry on the left side panel under *Policy*. .. image:: srmPdpxPdpMgmt.png After initialization, there will be no policies loaded into the policy subsystem. This can be verified by accessing the Editor tab in the UI. PDP-D Active/Active Pool ^^^^^^^^^^^^^^^^^^^^^^^^ The PDP-Ds replicas will come up with the amsterdam controller installed in brainless mode (no maven coordinates) since the controller has not been associated with a set of drools rules to run (control loop rules). The following command can be issued on each of the PDP-D replicas IPs: .. code-block:: bash :caption: Querying the rules association for a PDP-D replica # Using default credentials for the drools telemetry service. # To change the default username and passwords for this service, # please modify configuration pre-installation at: # oom/kubernetes/policy/charts/drools/resources/config/opt/policy/config/drools/base.conf curl --silent --user 'demo@people.osaaf.org:demo123456!' -X GET http://:9696/policy/pdp/engine/controllers/amsterdam/drools | python -m json.tool { "alive": false, "artifactId": "NO-ARTIFACT-ID", "brained": false, "canonicalSessionNames": [], "container": null, "groupId": "NO-GROUP-ID", "locked": false, "recentSinkEvents": [], "recentSourceEvents": [], "sessionNames": [], "version": "NO-VERSION" } Before Installing Policies ^^^^^^^^^^^^^^^^^^^^^^^^^^ It has been experienced in large OOM k8s multi-node full ONAP installations that components DNS and connectivity problems across pods through services. Eventually, the system becomes stable and ready to be used. Single node, smaller installations, do not seem to have these issues. Give the system enough time to make sure it has been initialized properly before pushing policies. Make sure the policy subsystem is initialized by: 1. Verify that the "PDP Management" screen shows the 1 pooled PDP-X "UP_TO_DATE". If the PDP-X does not show the correct state, restart the faulty one to force re-synchronization with the pap. .. code-block:: bash :caption: Force re-synchronization of a PDP-X kubectl exec -it dev-pdp-0 --container pdp -n onap -- bash -c "source /opt/app/policy/etc/profile.d/env.sh; policy.sh stop; policy.sh start" # bounce the BRMSGW as well since it synchronizes with PDP-Xs via websockets: kubectl exec -it dev-brmsgw-b877bc567-wbnbz -n onap -- bash -c "source /opt/app/policy/etc/profile.d/env.sh; policy.sh stop; policy.sh start" 2.

There is a sample script used by integration teams to load policies to support all four use cases at: */tmp/policy-install/config/push-policies.sh* in the pap container within the pap pod. This script can be modified for your own particular installation, for example if only interested in vCPE use cases, remove those vCPE related API REST calls. For the vFW use case, you may want to edit the encoded operational policy to point to the proper resourceID in your installation. The above mentioned *push-policies.sh* script can be executed as follows: .. code-block:: bash :caption: Installing the default policies # NOTE: If modifications are required to the /tmp/policy-install/config/push-policies.sh, it should be copied # to a different location, for example /tmp as /tmp/policy-install/config directory is read-only. kubectl exec -it dev-pap-8587696769-vwj6k -c pap -n onap -- bash -c "export PRELOAD_POLICIES=true; /tmp/policy-install/config/push-policies.sh" ..

The policies pushed could be viewed eventually through the Policy UI: .. image:: srmEditor.png As part of the process pushing of policies through the policy, the brmsgw component will compose drools rules artifacts and publish them to the nexus respository at ``http://:30236/nexus/``. .. image:: srmNexus.png At the same time each replica of the PDP-Ds will receive notifications for each new version of the policies to run for the Amsterdam controller. The following command can be run to see how the amsterdam controller is associated with the latest rules version. The following command can be used for verifying each replica: .. code-block:: none :caption: Querying the rules association of a PDP-D replica # Using default credentials for the drools telemetry service. # To change the default username and passwords for this service, # please modify configuration pre-installation at: # oom/kubernetes/policy/charts/drools/resources/config/opt/policy/config/drools/base.conf curl --silent --user 'demo@people.osaaf.org:demo123456!' -X GET http://:9696/policy/pdp/engine/controllers/amsterdam/drools | python -m json.tool { "alive": true, "artifactId": "policy-amsterdam-rules", "brained": true, "groupId": "org.onap.policy-engine.drools.amsterdam", "locked": false, "modelClassLoaderHash": 1223551265, "recentSinkEvents": [], "recentSourceEvents": [], "sessionCoordinates": [ "org.onap.policy-engine.drools.amsterdam:policy-amsterdam-rules:0.4.0:closedloop-amsterdam" ], "sessions": [ "closedloop-amsterdam" ], "version": "0.4.0" } Likewise, for verification purposes, each PDP-X replica can be queried directly to retrieve policy information.
