CPS OOM Charts
==============
The CPS kubernetes chart is located in the `OOM repository <https://github.com/onap/oom/tree/master/kubernetes/cps>`_.
This chart includes different cps components referred as <cps-component-name> further in the document are listed below:
.. container:: ulist
- `cps-core <https://github.com/onap/oom/tree/master/kubernetes/cps/components/cps-core>`__
- `ncmp-dmi-plugin <https://github.com/onap/oom/tree/master/kubernetes/cps/components/ncmp-dmi-plugin>`__
Please refer to the `OOM documentation <https://docs.onap.org/projects/onap-oom/en/latest/sections/guides/user_guides/oom_user_guide.html>`_ on how to install and deploy ONAP.
Installing or Upgrading CPS Components
======================================
The assumption is you have cloned the charts from the OOM repository into a local directory.
**Step 1** Go to the cps charts and edit properties in values.yaml files to make any changes to particular cps component if required.
.. code-block:: bash
cd oom/kubernetes/cps/components/<cps-component-name>
**Step 2** Build the charts
.. code-block:: bash
cd oom/kubernetes
make SKIP_LINT=TRUE cps
.. note::
SKIP_LINT is only to reduce the "make" time
**Step 3** Undeploying already deployed cps components
After undeploying cps components, keep monitoring the cps pods until they go away.
.. code-block:: bash
helm del --purge <my-helm-release>-<cps-component-name>
kubectl get pods -n <namespace> | grep <cps-component-name>
**Step 4** Make sure there is no orphan database persistent volume or claim.
First, find if there is an orphan database PV or PVC with the following commands:
.. note::
This step does not apply to ncmp-dmi-plugin.
.. code-block:: bash
kubectl get pvc -n <namespace> | grep <cps-component-name>
kubectl get pv -n <namespace> | grep <cps-component-name>
If there are any orphan resources, delete them with
.. code-block:: bash
kubectl delete pvc <orphan-cps-core-pvc-name>
kubectl delete pv <orphan-cps-core-pv-name>
**Step 5** Delete NFS persisted data for CPS components
Connect to the machine where the file system is persisted and then execute the below command
.. code-block:: bash
rm -fr /dockerdata-nfs/<my-helm-release>/<cps-component-name>
**Step 6** Re-Deploy cps pods
After deploying cps, keep monitoring the cps pods until they come up.
.. code-block:: bash
helm deploy <my-helm-release> local/cps --namespace <namespace>
kubectl get pods -n <namespace> | grep <cps-component-name>
Restarting a faulty component
=============================
Each cps component can be restarted independently by issuing the following command:
.. code-block:: bash
kubectl delete pod <cps-component-pod-name> -n <namespace>
.. Below Label is used by documentation for other CPS components to link here, do not remove even if it gives a warning
.. _cps_common_credentials_retrieval:
Credentials Retrieval
=====================
Application and database credentials are kept in Kubernetes secrets. They are defined as external secrets in the
values.yaml file to be used across different components as :
.. container:: ulist
- `cps-core <https://github.com/onap/oom/blob/master/kubernetes/cps/components/cps-core/values.yaml>`_
- `ncmp-dmi-plugin <https://github.com/onap/oom/blob/master/kubernetes/cps/components/ncmp-dmi-plugin/values.yaml>`_
Below are the list of secrets for different cps components.
+--------------------------+---------------------------------+---------------------------------------------------+
| Component | Secret type | Secret Name |
+==========================+=================================+===================================================+
| cps-core | Database authentication | <my-helm-release>-cps-core-pg-user-creds |
+--------------------------+---------------------------------+---------------------------------------------------+
| cps-core | Rest API Authentication | <my-helm-release>-cps-core-app-user-creds |
+--------------------------+---------------------------------+---------------------------------------------------+
| ncmp-dmi-plugin | Rest API Authentication | <my-helm-release>-cps-dmi-plugin-user-creds |
+--------------------------+---------------------------------+---------------------------------------------------+
| ncmp-dmi-plugin | SDNC authentication | <my-helm-release>-ncmp-dmi-plugin-sdnc-creds |
+--------------------------+---------------------------------+---------------------------------------------------+
The credential values from these secrets are configured in running container as environment variables. Eg:
`cps core deployment.yaml <https://github.com/onap/oom/blob/master/kubernetes/cps/components/cps-core/templates/deployment.yaml>`_
If no specific passwords are provided to the chart as override values for deployment, then passwords are automatically
generated when deploying the Helm release. Below command can be used to retrieve application property credentials
.. code::
kubectl get secret <my-helm-release>-<secret-name> -n <namespace> -o json | jq '.data | map_values(@base64d)'
.. note::
base64d works only with jq version 1.6 or above.
CPS Core Pods
=============
To get a listing of the cps-core Pods, run the following command:
.. code-block:: bash
kubectl get pods -n <namespace> | grep cps-core
dev-cps-core-ccd4cc956-r98pv 1/1 Running 0 24h
dev-cps-core-postgres-primary-f7766d46c-s9d5b 1/1 Running 0 24h
dev-cps-core-postgres-replica-84659d68f9-6qnt4 1/1 Running 0 24h
.. note::
The CPS Service will have to be restarted each time a change is made to a configurable property.

values to configure the application to be deployed. This list is not exhaustive.

CPS-Core Docker Installation
============================
CPS-Core can also be installed in a docker environment. Latest `docker-compose <https://github.com/onap/cps/blob/master/docker-compose/docker-compose.yml>`_ is included in the repo to start all the relevant services.
The latest instructions are covered in the `README <https://github.com/onap/cps/blob/master/docker-compose/README.md>`_.

.. _cps_common_distributed_datastructures:
CPS-Core and NCMP Distributed Datastructures
============================================
CPS-Core and NCMP both internally uses embedded distributed datastructure to replicate the state across various instances for low latency.
These instances require some additional ports to be available. The default range starts from 5701 and based on the number of instances configured they are incremented sequentially.
Below are the list of distributed datastructures that we have.
