:depth: 3
The new Beijing release capabilities for OOM are described here.
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 <none> 9989:30216/TCP 24m
onap drools NodePort 10.43.27.92 <none> 6969:30217/TCP,9696:30221/TCP 24m
onap nexus NodePort 10.43.19.171 <none> 8081:30236/TCP 24m
onap pap NodePort 10.43.9.166 <none> 8443:30219/TCP,9091:30218/TCP 24m
onap pdp ClusterIP None <none> 8081/TCP 24m
onap policydb ClusterIP None <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 'healthcheck:zb!XztG34' -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://<oom-vm>: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 '@1b3rt:31nst31n' -X GET http://<drools-replica-ip>: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. Verify service name resolution is OK across policy components
.. code-block:: bash
:caption: Verify policy services connectivity
# pick any policy pod to run these tests from:
# kubectl get pods --all-namespaces -o=wide
kubectl exec -it dev-brmsgw-b877bc567-wbnbz -n onap -- bash -c "ping policydb"
kubectl exec -it dev-brmsgw-b877bc567-wbnbz -n onap -- bash -c "ping pdp"
kubectl exec -it dev-brmsgw-b877bc567-wbnbz -n onap -- bash -c "ping drools"
kubectl exec -it dev-brmsgw-b877bc567-wbnbz -n onap -- bash -c "ping nexus"
kubectl exec -it dev-brmsgw-b877bc567-wbnbz -n onap -- bash -c "ping message-router"
Installing Policies
^^^^^^^^^^^^^^^^^^^
The OOM default installation will come with no policies pre-configured. 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.

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://<oom-vm>: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

PDP-X Resiliency
^^^^^^^^^^^^^^^^
A PDP-X container failure can be simulated by either:
a) performing a"policy.sh stop" operation within the PDP-X container, which in fact will shutdown the PDP-X service, and eventually will be detected by the liveness checks, or
b) by plainly deleting the corresponding pod.
In the following example, the PDP-X 0 is forced to fail.
.. code-block:: bash
:caption: Causing PDP-X 0 service to fail
# In these scenarios the liveness check will fail and recovery actions will take place.
# Alternative 1: In this scenario we shutdown the PDP-X 0 service, so the liveness monitored ports will be down
# (but the pod is up) and corrective measures will be applied
ubuntu@k8sx:~$ kubectl exec -it dev-pdp-0 --container pdp -n onap -- bash -c "source /opt/app/policy/etc/profile.d/env.sh; policy.sh stop;"
pdplp: STOPPING ..
pdp: STOPPING ..
# Alternative 2: Brute force delete of the PDP-X 0 pod.
ubuntu@k8sx:~$ kubectl delete pod dev-pdp-0 -n onap
pod "dev-pdp-0" deleted
Upon detection of the service being down through the liveness check, the container will be restarted. Note the **restart count** when querying the status of the pods:
.. code-block:: bash
:caption: Checking PDP-X 0 restart count
ubuntu@k8sx:~$ kubectl get pods --all-namespaces -o=wide
NAMESPACE NAME READY STATUS RESTARTS AGE IP NODE

onap dev-policydb-587d55bdff-4f5dz 1/1 Running 0 3d 10.42.12.242 k8sx
During the restart process, the PAP component, will detect that PDP-X 0 is down and therefore its state being reflected in the PDP-X screen:
.. image:: srmPdpxResiliencyPdpMgmt1.png
This screen will be updated to reflect PDP-X 0 is back alive, after PDP-X 0 synchronizes itself with the PAP.
.. image:: srmPdpxResiliencyPdpMgmt2.png
At that point, the PDP-X is usable either directly or through the service to query for policies.

PDP-D Resiliency
^^^^^^^^^^^^^^^^
A PDP-D container failure can be simulated by either:
a) performing a"policy stop" operation within the PDP-D pod, which in fact will shutdown the PDP-D service, and eventually will be detected by the liveness checks, or
b) by plainly deleting the corresponding pod.
In the following example, the PDP-D 0 is forced to fail.
.. code-block:: bash
:caption: Causing PDP-D 0 to fail
# In these scenarios the liveness check will fail and recovery actions will take place.
# Alternative 1: in this scenario we shutdown the PDP-D 0 policy process, so the liveness monitored ports
# will be down (but the pod is up) and corrective measures will be applied
ubuntu@k8sx:~/oom/kubernetes$ kubectl exec -it dev-drools-0 --container drools -n onap -- bash -c "source /opt/app/policy/etc/profile.d/env.sh; policy stop"
[drools-pdp-controllers]
L []: Stopping Policy Management... Policy Management (pid=3284) is stopping... Policy Management has stopped.
Upon detection of the service being down through the liveness check, the container will be restarted. Note the restart count when querying the status of the pods:
.. code-block:: bash
:caption: Checking PDP-D 0 restart count
ubuntu@k8sx:~$ kubectl get pods --all-namespaces -o=wide | grep drool
onap dev-drools-0 0/1 Running 0 1d 10.42.10.21 k8sx

Verification that the restarted PDP-D 0 comes up with the appropriate policy loaded can be verified by checking its maven coordinates:
.. code-block:: bash

PDP-X Scaling
^^^^^^^^^^^^^
To scale a new PDP-X, set the replica count appropriately.
In our tests below, we are going to work with the OOM policy component in isolation. In this exercise, we scale the PDP-X with 1 additional replica, PDP-X 1.
.. code-block:: bash
:caption: Scaling a PDP-X
ubuntu@k8sx:~$ helm upgrade -i dev local/onap --namespace onap --set global.pullPolicy=IfNotPresent --set policy.pdp.replicaCount=2

Check Policy Engine UI how the PDP-Xs are coming up and request policies to the PAP.
Eventually the new PDP-X will be connected and serving policies:

PDP-D Scaling
^^^^^^^^^^^^^
To scale a new PDP-D, set the replica count appropriately. In our scenario below, we are going to scale the PDP-D service to add a new pod (2 active PDP-Ds).
.. code-block:: bash
:caption: Scaling a PDP-D
# Note: we also set the PDP-X pool to 2 instances (matching the previous section)
ubuntu@k8sx:~$ helm upgrade -i dev local/onap --namespace onap --set global.pullPolicy=IfNotPresent --set policy.pdp.replicaCount=2 --set policy.drools.replicaCount=2
Release "dev" has been upgraded. Happy Helming!
