| 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 |
| ******************************* |
| 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. |
