| 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. |

| ============================ |
| |
| 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. |

| 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. |
