  15 CPS OOM Charts
  16 --------------
  17 The CPS kubernetes chart is located in the `OOM repository <https://github.com/onap/oom/tree/master/kubernetes/cps>`_.
  18 This chart includes different cps components referred as <cps-component-name> further in the document are listed below:
  19
  20 .. container:: ulist
  21
  22   - `cps-core <https://github.com/onap/oom/tree/master/kubernetes/cps/components/cps-core>`_
  23   - `cps-temporal <https://github.com/onap/oom/tree/master/kubernetes/cps/components/cps-temporal>`_
  24   - `ncmp-dmi-plugin <https://github.com/onap/oom/tree/master/kubernetes/cps/components/ncmp-dmi-plugin>`_
  25
  26 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.
  27
  28 Installing or Upgrading CPS Components
  29 --------------------------------------
  30 The assumption is you have cloned the charts from the OOM repository into a local directory.
  31
  32 **Step 1** Go to the cps charts and edit properties in values.yaml files to make any changes to particular cps component if required.
  33
  34 .. code-block:: bash
  35
  36   cd oom/kubernetes/cps/components/<cps-component-name>
  37
  38 **Step 2** Build the charts
  39
  40 .. code-block:: bash
  41
  42   cd oom/kubernetes
  43   make SKIP_LINT=TRUE cps
  44
  45 .. note::
  46    SKIP_LINT is only to reduce the "make" time
  47
  48 **Step 3** Undeploying already deployed cps components
  49
  50 After undeploying cps components, keep monitoring the cps pods until they go away.
  51
  52 .. code-block:: bash
  53
  54   helm del --purge <my-helm-release>-<cps-component-name>
  55   kubectl get pods -n <namespace> | grep <cps-component-name>
  56
  57 **Step 4** Make sure there is no orphan database persistent volume or claim.
  58
  59 First, find if there is an orphan database PV or PVC with the following commands:
  60
  61 .. note::
  62    This step does not apply to ncmp-dmi-plugin.
  63
  64 .. code-block:: bash
  65
  66   kubectl get pvc -n <namespace> | grep <cps-component-name>
  67   kubectl get pv -n <namespace> | grep <cps-component-name>
  68
  69 If there are any orphan resources, delete them with
  70
  71 .. code-block:: bash
  72
  73     kubectl delete pvc <orphan-cps-core-pvc-name>
  74     kubectl delete pv <orphan-cps-core-pv-name>
  75
  76 **Step 5** Delete NFS persisted data for CPS components
  77
  78 Connect to the machine where the file system is persisted and then execute the below command
  79
  80 .. code-block:: bash
  81
  82   rm -fr /dockerdata-nfs/<my-helm-release>/<cps-component-name>
  83
  84 **Step 6** Re-Deploy cps pods
  85
  86 After deploying cps, keep monitoring the cps pods until they come up.
  87
  88 .. code-block:: bash
  89
  90   helm deploy <my-helm-release> local/cps --namespace <namespace>
  91   kubectl get pods -n <namespace> | grep <cps-component-name>
  92
  93 Restarting a faulty component
  94 -----------------------------
  95 Each cps component can be restarted independently by issuing the following command:
  96
  97 .. code-block:: bash
  98
  99     kubectl delete pod <cps-component-pod-name> -n <namespace>
 100
 101 .. Below Label is used by documentation for other CPS components to link here, do not remove even if it gives a warning
 102 .. _cps_common_credentials_retrieval:
 103
 104 Credentials Retrieval
 105 ---------------------
 106
 107 Application and database credentials are kept in Kubernetes secrets. They are defined as external secrets in the
 108 values.yaml file to be used across different components as :
 109
 110 .. container:: ulist
 111
 112   - `cps-core <https://github.com/onap/oom/blob/master/kubernetes/cps/components/cps-core/values.yaml#L18>`_
 113   - `cps-temporal <https://github.com/onap/oom/blob/master/kubernetes/cps/components/cps-temporal/values.yaml#L28>`_
 114   - `ncmp-dmi-plugin <https://github.com/onap/oom/blob/master/kubernetes/cps/components/ncmp-dmi-plugin/values.yaml#L22>`_
 115
 116 Below are the list of secrets for different cps components.
 117
 118 +--------------------------+---------------------------------+---------------------------------------------------+
 119 | Component                | Secret type                     | Secret Name                                       |
 120 +==========================+=================================+===================================================+
 121 | cps-core                 | Database authentication         | <my-helm-release>-cps-core-pg-user-creds          |
 122 +--------------------------+---------------------------------+---------------------------------------------------+
 123 | cps-core                 | Rest API Authentication         | <my-helm-release>-cps-core-app-user-creds         |
 124 +--------------------------+---------------------------------+---------------------------------------------------+
 125 | cps-temporal             | Rest API Authentication         | <my-helm-release>-cps-temporal-app-user-creds     |
 126 +--------------------------+---------------------------------+---------------------------------------------------+
 127 | cps-temporal             | Database authentication         | <my-helm-release>-cps-temporal-pg-user-creds      |
 128 +--------------------------+---------------------------------+---------------------------------------------------+
 129 | ncmp-dmi-plugin          | Rest API Authentication         | <my-helm-release>-cps-dmi-plugin-user-creds       |
 130 +--------------------------+---------------------------------+---------------------------------------------------+
 131 | ncmp-dmi-plugin          | SDNC authentication             | <my-helm-release>-ncmp-dmi-plugin-sdnc-creds      |
 132 +--------------------------+---------------------------------+---------------------------------------------------+
 133
 134 The credential values from these secrets are configured in running container as environment variables. Eg:
 135 `cps core deployment.yaml <https://github.com/onap/oom/blob/master/kubernetes/cps/components/cps-core/templates/deployment.yaml#L46>`_
 136
 137 If no specific passwords are provided to the chart as override values for deployment, then passwords are automatically
 138 generated when deploying the Helm release. Below command can be used to retrieve application property credentials
 139
 140 .. code::
 141
 142   kubectl get secret <my-helm-release>-<secret-name> -n <namespace> -o json | jq '.data | map_values(@base64d)'
 143
 144 .. note::
 145    base64d works only with jq version 1.6 or above.
 146
 147 CPS Core Pods
 148 =============
 149 To get a listing of the cps-core Pods, run the following command:
 150
 151 .. code-block:: bash
 152
 153   kubectl get pods -n <namespace> | grep cps-core
 154
 155   dev-cps-core-ccd4cc956-r98pv                          1/1     Running            0          24h
