Policy/ACM OOM Installation
---------------------------
.. contents::
:depth: 2
Notes
*****
* This guide assumes that you have access to a Kubernetes cluster.
* The examples for this guide were carried out on a 3 node Ubuntu-based cluster. However, cluster software such as microk8s should work just as well.
Cluster Used in this Guide
**************************
* Ubuntu-based cluster using Ubuntu 20.04.1 LTS
* 3 nodes - each having 8GB RAM and 4CPU
Prerequisites
*************
* K8s Cluster capable of running kubectl commands
* Both kubectl client and the server use v1.22.4
* Helm version v3.6.3 is installed
* There should be a running chart repo called "local"
* Chartmuseum used to create the chart repo
Deploy Policy/ACM OOM & Required 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>`_.
Install Helm Plugins
^^^^^^^^^^^^^^^^^^^^
Chart museum's **helm-push** plugin should be installed
.. code-block:: bash
helm plugin install https://github.com/chartmuseum/helm-push --version 0.10.3
And then we should install the **deploy** and **undeploy** plugins from oom. so, navigate to the oom/kubernetes directory in the above cloned oom gerrit repo.
.. code-block:: bash
helm plugin install helm/plugins/deploy
helm plugin install helm/plugins/undeploy
Package and Upload Charts to Repo
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Navigate to the same oom/kubernetes directory. The **make** command can be used here to package and upload (among other things) the charts to the local chart repo. This command is slow as it has to package and upload all of the helm charts in oom. However, we are skipping linting of the charts and using the **-j** flag to allow us to use multiple threads - this will maximize the speed.
.. code-block:: bash
make all SKIP_LINT=TRUE -j$(nproc)
Once this is completed, we should be able to see all of the charts in the local helm repo.
.. code-block:: bash
helm search repo local
local/policy 12.0.0 ONAP Policy
local/policy-apex-pdp 12.0.0 ONAP Policy APEX PDP
local/policy-api 12.0.0 ONAP Policy Design API
local/policy-clamp-ac-a1pms-ppnt 12.0.0 ONAP Policy Clamp A1PMS Participant
local/policy-clamp-ac-http-ppnt 12.0.0 ONAP Policy Clamp Controlloop Http Participant
local/policy-clamp-ac-k8s-ppnt 12.0.0 ONAP Policy Clamp Controlloop K8s Participant
local/policy-clamp-ac-kserve-ppnt 12.0.0 ONAP Policy Clamp Kserve Participant
local/policy-clamp-ac-pf-ppnt 12.0.0 ONAP Policy Clamp Controlloop Policy Participant

local/policy-pap 12.0.0 ONAP Policy Administration (PAP)
local/policy-xacml-pdp 12.0.0 ONAP Policy XACML PDP (PDP-X)
.. note::
Only the policy/acm charts are shown above - there will be many others.
Strimzi Kafka and Cert Manager Install
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Install Cert Manager
.. code-block:: bash
kubectl apply -f https://github.com/jetstack/cert-manager/releases/download/v1.2.0/cert-manager.yaml
Currently, the following policy/acm components use Strimzi Kafka by default:
* policy-ppnt
* k8s-ppnt
* http-ppnt
* a1Policy-mgmt-ppnt
* kserve-ppnt
* acm runtime
There is a future plan to move all components to Strimzi Kafka. However, in the meantime, our deployments require both DMAAP message-router and Strimzi Kafka
|
Install Strimzi Kafka Operator
.. code-block:: bash
helm repo add strimzi https://strimzi.io/charts/
helm install strimzi-kafka-operator strimzi/strimzi-kafka-operator --namespace strimzi-system --version 0.32.0 --set watchAnyNamespace=true --create-namespace
Once these are installed and running, we can move on to the installation of the policy and related helm charts
Policy and Related Helm Chart Install
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
At this stage, we have all the required charts that we need for either Policy Framework or ACM installation. The command to deploy the charts is below
.. code-block:: bash
helm deploy dev local/onap --namespace onap -f ~/override.yaml --create-namespace
In the above **helm deploy** command we provide an override file called **override.yaml**. In this file, we can turn on/off different parts of the onap installation. we have provided 2 different override files below in the collapsable code. One is for just the policy components and requirements. One is for the ACM components and requirements. These are provided just as examples - you can adjust any way you see fit.

Policy/ACM Pods
***************
To get a listing of the Policy or ACM Pods, run the following command:
.. code-block:: bash
kubectl get pods -n onap | grep dev-policy
dev-policy-59684c7b9c-5gd6r 2/2 Running 0 8m41s
dev-policy-apex-pdp-0 1/1 Running 0 8m41s
dev-policy-api-56f55f59c5-nl5cg 1/1 Running 0 8m41s
dev-policy-distribution-54cc59b8bd-jkg5d 1/1 Running 0 8m41s
dev-policy-mariadb-0 1/1 Running 0 8m41s
dev-policy-xacml-pdp-765c7d58b5-l6pr7 1/1 Running 0 8m41s
.. note::
To get a listing of the Policy services, run this command:
kubectl get svc -n onap | grep policy
Accessing Policy/ACM 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
.. _install-upgrade-policy-label:
Installing or Upgrading Policy/ACM
**********************************
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.
The policy schema will be installed automatically as part of the database configuration using ``db-migrator``.
By default the policy schema is upgraded to the latest version.
For more information on how to change the ``db-migrator`` setup please see
:ref:`Using Policy DB Migrator <policy-db-migrator-label>`.
**Step 2** Build the charts
.. code-block:: bash
make policy -j$(nproc)
make SKIP_LINT=TRUE onap -j$(nproc)
.. note::
SKIP_LINT is only to reduce the "make" time. **-j** allows the use of multiple threads.
**Step 3** Undeploy Policy/ACM
After undeploying policy, loop on monitoring the policy pods until they go away.
.. code-block:: bash
helm undeploy dev-policy
kubectl get pods -n onap | grep dev-policy
**Step 4** 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 | grep dev-policy
.. note::
If you want to purge the existing data and start with a clean install,
please follow these steps after undeploying:
**Step 1** Delete NFS persisted data for Policy
.. code-block:: bash
rm -fr /dockerdata-nfs/dev/policy
**Step 2** Make sure there is no orphan policy database persistent volume or claim.
First, find if there is an orphan database PV or PVC with the following commands:
.. code-block:: bash
kubectl get pvc -n onap | grep policy
kubectl get pv -n onap | grep policy
If there are any orphan resources, delete them with
.. code-block:: bash
kubectl delete pvc <orphan-policy-mariadb-resource>
kubectl delete pv <orphan-policy-mariadb-resource>
Restarting a faulty component
*****************************
Each policy component can be restarted independently by issuing the following command:
.. code-block:: bash
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
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/components/policy-drools-pdp/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:`install-upgrade-policy-label`).
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 *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:`install-upgrade-policy-label` 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
|
