Policy OOM Installation
-----------------------

:depth: 2
Policy OOM Charts
*****************
The policy K8S charts are located in the `OOM repository <https://gerrit.onap.org/r/gitweb?p=oom.git;a=tree;f=kubernetes/policy;h=78576c7a0d30cb87054e9776326cdde20986e6e3;hb=refs/heads/master>`_.
Please refer to the OOM documentation on how to install and deploy ONAP.
Policy Pods
***********
To get a listing of the Policy Pods, run the following command:
.. code-block:: bash
kubectl get pods | grep policy
brmsgw ClusterIP 10.43.77.177 <none> 9989/TCP 5d15h app=brmsgw,release=dev-policy
drools ClusterIP 10.43.167.154 <none> 6969/TCP,9696/TCP 5d15h app=drools,release=dev-policy
nexus ClusterIP 10.43.239.92 <none> 8081/TCP 5d15h app=nexus,release=dev-policy
pap NodePort 10.43.207.229 <none> 8443:30219/TCP,9091:30218/TCP 5d15h app=pap,release=dev-policy
pdp ClusterIP None <none> 8081/TCP 5d15h app=pdp,release=dev-policy
policy-apex-pdp ClusterIP 10.43.226.0 <none> 6969/TCP 5d15h app=policy-apex-pdp,release=dev-policy
policy-api ClusterIP 10.43.102.56 <none> 6969/TCP 5d15h app=policy-api,release=dev-policy
policy-distribution ClusterIP 10.43.4.211 <none> 6969/TCP 5d15h app=policy-distribution,release=dev-policy
policy-pap ClusterIP 10.43.175.164 <none> 6969/TCP 5d15h app=policy-pap,release=dev-policy
policy-xacml-pdp ClusterIP 10.43.181.208 <none> 6969/TCP 5d15h app=policy-xacml-pdp,release=dev-policy
policydb ClusterIP 10.43.93.233 <none> 3306/TCP 5d15h app=policydb,release=dev-policy
Some of these pods are shared between the legacy components and the latest framework components, while others are not.

Accessing Policy Containers
***************************
Accessing the policy docker containers is the same as for any kubernetes container. Here is an example:
.. code-block:: bash
kubectl -n onap exec -it dev-policy-policy-xacml-pdp-584844b8cf-9zptx bash
Installing or Upgrading Policy
******************************
The assumption is you have cloned the charts from the OOM repository into a local directory.
**Step 1** Go into local copy of OOM charts
From your local copy, edit any of the values.yaml files in the policy tree to make desired changes.
**Step 2** Build the charts
.. code-block:: bash
make policy
make onap
**Step 3** Undeploy Policy
After undeploying policy, loop on monitoring the policy pods until they go away.
.. code-block:: bash
helm del --purge dev-policy
kubectl get pods -n onap
**Step 4** Delete NFS persisted data for Policy
Sudo to root if you logged in using another account such as ubuntu.
.. code-block:: bash
rm -fr /dockerdata-nfs/dev-policy
**Step 5** Re-Deploy Policy pods
After deploying policy, loop on monitoring the policy pods until they come up.
.. code-block:: bash
helm deploy dev-policy local/onap --namespace onap
kubectl get pods -n onap
Restarting a faulty component
*****************************
Each policy component can be restarted independently by issuing the following command:
kubectl delete pod <policy-pod> -n onap
Exposing ports
**************
For security reasons, the ports for the policy containers are configured as ClusterIP and thus not exposed. If you find you need those ports in a development environment, then the following will expose them.
.. code-block:: bash
kubectl -n onap expose service policy-api --port=7171 --target-port=6969 --name=api-public --type=NodePort
Overriding certificate stores
*******************************
Policy components package default key and trust stores that support https based communication with other
AAF-enabled ONAP components. Each store can be overridden at installation.
To override a default keystore, the new certificate store (policy-keystore) file should be placed at the
appropriate helm chart locations below:
* oom/kubernetes/policy/charts/drools/resources/secrets/policy-keystore drools pdp keystore override.
* oom/kubernetes/policy/charts/policy-apex-pdp/resources/config/policy-keystore apex pdp keystore override.
* oom/kubernetes/policy/charts/policy-api/resources/config/policy-keystore api keystore override.
* oom/kubernetes/policy/charts/policy-distribution/resources/config/policy-keystore distribution keystore override.
* oom/kubernetes/policy/charts/policy-pap/resources/config/policy-keystore pap keystore override.
* oom/kubernetes/policy/charts/policy-xacml-pdp/resources/config/policy-keystore xacml pdp keystore override.
In the event that the truststore (policy-truststore) needs to be overriden as well, place it at the appropriate
location below:
* oom/kubernetes/policy/charts/drools/resources/configmaps/policy-truststore drools pdp truststore override.
* oom/kubernetes/policy/charts/policy-apex-pdp/resources/config/policy-truststore apex pdp truststore override.
* oom/kubernetes/policy/charts/policy-api/resources/config/policy-truststore api truststore override.
* oom/kubernetes/policy/charts/policy-distribution/resources/config/policy-truststore distribution truststore override.
* oom/kubernetes/policy/charts/policy-pap/resources/config/policy-truststore pap truststore override.
* oom/kubernetes/policy/charts/policy-xacml-pdp/resources/config/policy-truststore xacml pdp truststore override.
When the keystore passwords are changed, the corresponding component configuration ([1]_) should also change:
* oom/kubernetes/policy/charts/drools/values.yaml
* oom/kubernetes/policy-apex-pdp/resources/config/config.json
* oom/kubernetes/policy-distribution/resources/config/config.json
This procedure is applicable to an installation that requires either AAF or non-AAF derived certificates.
The reader is refered to the AAF documentation when new AAF-compliant keystores are desired:
* `AAF automated configuration and Certificates <https://docs.onap.org/en/latest/submodules/aaf/authz.git/docs/sections/configuration/AAF_4.1_config.html#typical-onap-entity-info-in-aaf>`_.
* `AAF Certificate Management for Dummies <https://wiki.onap.org/display/DW/AAF+Certificate+Management+for+Dummies>`_.
* `Instructional Videos <https://wiki.onap.org/display/DW/Instructional+Videos>`_.
After these changes, follow the procedures in the :ref:`Installing or Upgrading Policy` section to make usage of
the new stores effective.
Additional PDP-D Customizations
*******************************
Credentials and other configuration parameters can be set as values
when deploying the policy (drools) subchart. Please refer to
`PDP-D Default Values <https://git.onap.org/oom/tree/kubernetes/policy/charts/drools/values.yaml>`_
for the current default values. It is strongly recommended that sensitive
information is secured appropriately before using in production.
Additional customization can be applied to the PDP-D. Custom configuration goes under the
"resources" directory of the drools subchart (oom/kubernetes/policy/charts/drools/resources).
This requires rebuilding the policy subchart
(see section :ref:`Installing or Upgrading Policy`).
Configuration is done by adding or modifying configmaps and/or secrets.
Configmaps are placed under "drools/resources/configmaps", and
secrets under "drools/resources/secrets".
Custom configuration supportes these types of files:
* **\*.conf** files to support additional environment configuration.
* **features\*.zip** to add additional custom features.
* **\*.pre.sh** scripts to be executed before starting the PDP-D process.
* **\*.post.sh** scripts to be executed after starting the PDP-D process.
* **policy-keystore** to override the PDP-D policy-keystore.
* **policy-truststore** to override the PDP-D policy-truststore.
* **aaf-cadi.keyfile** to override the PDP-D AAF key.
* **\*.properties** to override or add properties files.
* **\*.xml** to override or add xml configuration files.
* **\*.json** to override json configuration files.
* **\*settings.xml** to override maven repositories configuration .
Examples
^^^^^^^^
To *disable AAF*, simply override the "aaf.enabled" value when deploying the helm chart
(see the OOM installation instructions mentioned above).
To *override the PDP-D keystore or trustore*, add a suitable replacement(s) under
"drools/resources/secrets". Modify the drools chart values.yaml with
new credentials, and follow the procedures described at
:ref:`Installing or Upgrading Policy` to redeploy the chart.
To *disable https* for the DMaaP configuration topic, add a copy of
`engine.properties <https://git.onap.org/policy/drools-pdp/tree/policy-management/src/main/server/config/engine.properties>`_
with "dmaap.source.topics.PDPD-CONFIGURATION.https" set to "false", or alternatively
create a ".pre.sh" script (see above) that edits this file before the PDP-D is
started.
To use *noop topics* for standalone testing, add a "noop.pre.sh" script under
oom/kubernetes/policy/charts/drools/resources/configmaps/:
.. code-block:: bash
#!/bin/bash
sed -i "s/^dmaap/noop/g" $POLICY_HOME/config/*.properties
.. rubric:: Footnotes
.. [1] There is a limitation that store passwords are not configurable for policy-api, policy-pap, and policy-xacml-pdp.
