+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:
-End of Document
+.. code-block:: bash
+ kubectl get pods | grep policy
+
+ brmsgw ClusterIP 10.43.77.177 <none> 9989/TCP 5d15h app=brmsgw,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
+*******************************
+Each policy component keystore and or truststore can be overriden. The procedure will be applicable
+to an installation that requires certificates other than the pre-packaged AAF derived ones
+that come with the official ONAP distribution.
+
+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.
+
+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:`Rebuilding and/or modifying the Policy Charts`).
+
+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.
+
+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:`Rebuilding and/or modifying the Policy Charts` 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.
