 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>`_
   - `cps-temporal <https://github.com/onap/oom/tree/master/kubernetes/cps/components/cps-temporal>`_
   - `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/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#L18>`_
   - `cps-temporal <https://github.com/onap/oom/blob/master/kubernetes/cps/components/cps-temporal/values.yaml#L28>`_
   - `ncmp-dmi-plugin <https://github.com/onap/oom/blob/master/kubernetes/cps/components/ncmp-dmi-plugin/values.yaml#L22>`_

 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         |
 +--------------------------+---------------------------------+---------------------------------------------------+
 | cps-temporal             | Rest API Authentication         | <my-helm-release>-cps-temporal-app-user-creds     |
 +--------------------------+---------------------------------+---------------------------------------------------+
 | cps-temporal             | Database authentication         | <my-helm-release>-cps-temporal-pg-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#L46>`_

 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.

 Additional CPS-Core Customizations
 ==================================

 The following table lists some properties that can be specified as Helm chart
 values to configure the application to be deployed. This list is not exhaustive.

 Any spring supported property can be configured by providing in ``config.additional.<spring-supported-property-name>: value`` Example: config.additional.spring.datasource.hikari.maximumPoolSize: 30

 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 Deployment
	##############

	.. contents::
	:depth: 2

	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>`_
	- `cps-temporal <https://github.com/onap/oom/tree/master/kubernetes/cps/components/cps-temporal>`_
	- `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/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#L18>`_
	- `cps-temporal <https://github.com/onap/oom/blob/master/kubernetes/cps/components/cps-temporal/values.yaml#L28>`_
	- `ncmp-dmi-plugin <https://github.com/onap/oom/blob/master/kubernetes/cps/components/ncmp-dmi-plugin/values.yaml#L22>`_

	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 \|
	+--------------------------+---------------------------------+---------------------------------------------------+
	\| cps-temporal \| Rest API Authentication \| <my-helm-release>-cps-temporal-app-user-creds \|
	+--------------------------+---------------------------------+---------------------------------------------------+
	\| cps-temporal \| Database authentication \| <my-helm-release>-cps-temporal-pg-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#L46>`_

	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.

	Additional CPS-Core Customizations
	==================================

	The following table lists some properties that can be specified as Helm chart
	values to configure the application to be deployed. This list is not exhaustive.

	Any spring supported property can be configured by providing in ``config.additional.<spring-supported-property-name>: value`` Example: config.additional.spring.datasource.hikari.maximumPoolSize: 30
