How do I create a composite service?

Purpose

Service management’s composite services serve as a container object to which individual services (typically L2 and L3) can be attached and detached, regardless of their lifecycle state. This can be done without service interruption.

Service management’s composite services are created using a single intent type and can be fully managed, just like other, non-composite services. The underlying services that comprise a composite service can be viewed within service management and will appear in inventory requests. One service can belong to multiple composite services.

Auditing at the composite service level triggers audit operations on each underlying service that is in a deployed state. There is no deployment info trace at the composite service level.

The operational state, alignment, and service life cycle of the composite service is an aggregation of the corresponding state of its underlying services. For example, if all underlying services are aligned, the composite service will be aligned - otherwise, it is misaligned.

Note: Brownfield discovery, service supervision integration, and stitching are not available for composite services.

Before attempting to perform this procedure, ensure that you have read Service creation prerequisites.

Steps

Perform How do I create a service template?.

From the Service Management, Composite Services view, click + Composite Service.

The Create a composite service template to start form opens, displaying a list of service templates.

Click on a composite service template from the list.

The Create Service form opens with the Template Name parameter populated.

Configure the parameters, as required:

Parameter	Description
Service Name	Specifies the name of the composite service, which must be unique from other services created using the NSP.
Description	Describes the composite service

Click Deploy.

A dialog box appears.

Click Confirm.

The composite service is deployed.

Click (Table row actions), Contained Services in-line with the newly-created composite service.

A list of services attached to the composite service is displayed.

Perform one - or both - of the following, as needed:

Create a new service to attach to the composite service.
1. Click + Create.
  
  The Select a service template to start form opens.
2. The type of service template that you select will determine the type of service you will be creating.
  
  If you choose a service template based on a Nokia-provided intent type, you may use the procedures in this document to guide your service creation.
3. When service configuration is complete, click Deploy to attach the newly-created service to the composite service.
Attach an existing service to the composite service.
1. Click + Attach.
  
  A list of existing services is displayed.
2. Select one of more services in the list and click Attach.
  
  The selected services are attached to the composite service.

To detach a service from a composite service, click (Table row actions), Detach from composite in-line with any attached service.

A dialog box appears.

Click Detach. The service is detached from the composite service.
