| |
| #. Drag one or more elements from the Elements palette to the canvas. |
| #. To connect elements: |
| |
| #. Hover over an element and then hover over \ |image2|. |
| |
| Other elements that can connect to this element are highlighted. |
| |
| #. Drag to a highlighted element on the canvas. |
| #. Select options for Requirements and Capabilities. |
| #. Click Connect. |
| |
| #. To add artifacts at the service level: |
| |
| #. Click an empty area in the canvas and click *Deployment Artifacts* |
| (right pane). |
| #. Click \ |image3|. |
| #. Select the type. |
| #. Click Browse, locate a file to upload, and click Open. |
| #. Complete all other fields. |
| #. Click Done. |
| |
| Use this function to add YANG artifacts for distribution to SDNC. |
| |
| #. [Optional] At any time before checking in the Service, click |
| these options to update Service information: |
| |
| .. note:: These tasks can be done only before certifying the Service. |
| |
| - **General->Icon** change the icon associated with the Service |
| - **TOSCA Artifacts** view and edit artifacts, such as the .csar file |
| and TOSCA template |
| - **Composition** view or edit the graphical representation of the |
| service-level TOSCA model |
| - **Activity Log** view activity related to the Service |
| (displays the action, date, user, status, and any comments related to each |
| action) |
| - **Management Workflow** model service lifecycle workflows for execution |
| in SO (see `Create a Management Workflow [optional]`_) |
| - **Network Call Flow** model interactions among VFs (see `Create a |
| Network Callflow [optional]`_) |
| - **Deployment** view HEAT modules in VSPs |
| - **Properties Assignment** define or update properties, |
| policies and input parameters used during Service instantiation |
| (see `Add Service Inputs [optional]`_). |
| - **Monitoring** ... |
| |
| #. Click *Check In* to save changes. |
| |
| A box displays for confirming the changes. |
| |
| #. Enter a comment and click OK. |
| |
| A message displays when the Service is checked in and the |
| Home page is displayed. |
| |
| #. After creating a service and configuring optional fields, certify it |
| (see `Certify Service`_). |
| |
| Note: Create Service can also be invoked via External SDC API. |
| Refer SDC REST API reference for details of the API. |
| Currently, only a 'Partner Domain Service' category is supported |
| which cannot be created manually from SDC portal. |
| |
| .. _doc_guide_user_des_ser-cre_wf: |
| |
| Create a Management Workflow [optional] |
| --------------------------------------- |
| |
| Create a workflow to model the SO recipes of the service life cycle such |
| as instantiation, upgrade, termination, or suspension of a service or |
| VNF. In the workflow each of the Activity, represent API calls to |
| various ONAP components (such as OOF, SDN-C, App-C, etc) that perform a |
| business function needed. |
| |
| Note: The information collected in this section is represented in BPMN |
| format and included in distributed service model. |
| |
| **Prerequisites:** All the required ActivitySpec as supported by SO |
| are registered in SDC. |
| |
| #. From the SDC HOME page, click CATALOG and search for a service. |
| #. Click the service and click *Check Out*. |
| #. Select the panel *Management Workflow*. |
| #. Click *Add Workflow*. |
| #. The *Create New Workflow* box displays. |
| #. Complete all fields. |
| #. Click Create. |
| |
| |image7| |
| |
| #. Specify Inputs & Outputs of Workflow |
| #. Define the Composition of Workflow. |
| |
| #. All the Tasks in the composition are expected to be ServiceTask |
| for using Activities defined in SO. |
| #. Select the Implementation in the Task "general" tab to Activity. |
| #. Select the required ActivitySpec. |
| |
| #. Mark the workflow as executable by selecting the Executable flag in |
| the workflow "general" tab. |
| #. Click Save. |
| #. Certify the Workflow. |
| |
| .. _doc_guide_user_des_ser-cre_nfw: |
| |
| Create a Network Callflow [optional] |
| ------------------------------------ |
| |
| Create a network callflow to model the interactions among VFs within a |
| service, such how VFs interact to deliver a service while the service is |
| being consumed. In the model, lifelines represent VFs. |
| |
| Note: The information collected in this section is not distributed with |
| the service model. |
| |
| **Prerequisites:** `Create service`_ |
| |
| #. From the SDC HOME page, click CATALOG and search for the service. |
| #. Click the service and click *Check Out*. |
| #. Click Network Call Flow. |
| #. Click Add Workflow. |
| The Create New Workflow box displays. |
| #. Complete all fields. |
| #. Click Save. |
| #. In the new workflow pane, click the Lifelines icon. |
| |
| The LIFELINES/STEPS view displays. |
| |
| #. To add a lifeline (component), do the following: |
| |
| #. Click LIFELINES to expand the pane. |
| #. Click Add Lifeline. |
| #. In the [Unnamed Lifeline field], enter a name for the lifeline. |
| #. To add other lifelines to the workflow, repeat the actions above. |
| |
| #. After creating all required lifelines, do the following to add a step |
| (showing an action between two lifelines): |
| |
| #. Under STEPS (left pane), click Add Message. |
| An unnamed step is added under STEPS. |
| #. In the [Unnamed Message] field, enter a name or message for the |
| step. |
| #. From the component and arrow dropdown lists, select the two |
| components that communicate in this step, and the arrow to show in |
| which direction the communication flows. |
| #. To add another step, repeat the actions above. |
| |
| #. [Optional] Change the order of steps by clicking a step and dragging |
| it to the preferred position. |
| #. Click *Save*. |
| #. Click *Check In* to save changes. |

| by clicking the check box in each row as required. |
| Note: Do not select inputs that are already in the ENV file (this |
| overwrites values specified in the ENV). |
