Create a CDM application that is based on an existing service in the CMDB

  • Release version: Washingtondc
  • Updated February 1, 2024
  • 3 minutes to read

    • Create an application as the container for all config data for a service (an application service, application model, or dynamic CI group [infrastructure] in the CMDB).

    Before you begin

    Important:
    Starting with the Washington DC release, DevOps Config is being prepared for future deprecation. It will be hidden and no longer installed on new instances but will continue to be supported. For details, see the Deprecation Process [KB0867184] article in the Now Support Knowledge Base.

    Role required: CDM Admin [sn_cdm.cdm_admin]

    About this task

    For the application, you specify the number of deployables to generate and the SDLC environment that the deployables represent. When you upload existing config data into the application, the system maps the data as [name:value] pairs (config data items — CDIs) in the appropriate node in the data structure of the CDM application. For an overview of the process of preparing a new application to receive config data, see Preparing an application for config data upload.

    Procedure

    1. Select the Applications icon (Applications icon) to open the Create new application page and then select Application based on existing services to specify the CMDB service that the new application will hold config data for.

    2. Fill in the settings on the Create Deployables dialog box to specify the quantity and environment type of the deployables and the CMDB services to connect them to.
      Table 1. Create Deployables settings
      Field Description
      Environment The kind of code environment that is configured by the config data in the deployable.
      • Production
      • Development
      • Test
      Connection preference Option to connect the newly created deployables to services.
      • Auto-connect each new deployable to a service in the application model or dynamic CI group.
      • Manually specify the service to connect each new deployable to. You make the connections on the next page.
      Note:
      Because the DevOps pipeline applies config data in a deployable only to the services that the deployable is connected to, every deployable must be connected to a service.
      Quantity The number of deployables to create.

      If the number exceeds the number of services that are associated with the existing item in the CMDB, then the system generates new blank services.
      When you select Create, the system generates the application with the specified number and types of deployables and opens the Edit deployables tab for the application.
    3. Select Manage deployables to open the Edit deployables tab where you can configure the deployables.
    4. On the Edit deployables tab, update the settings for each deployable and then select Next.
      You connect each deployable to a service in the CMDB. The deployable holds the config data for its associated service.

      The system auto-saves your updates to settings.

      Table 2. Deployable details settings
      Field Description
      Deployable name Default name for the deployable that the system generates.

      Rename as needed.
      Deployable description Description that helps other users understand the purpose, scope, and intent of the deployable.
      Identifier Unique identifier that distinguishes this deployable from other deployables that share the same name and possibly many config data settings.

      For example, the production deployable that has the identifier Uraguay might have different config settings for the currency setting than the deployable that has the identifier Greenland.
      Connected to

      Service in the CMDB that is configured by the data in snapshots of the deployable. Select a service in the Available services list.

      Note:
      To continue, you must connect each deployable to a service.
      Perform one of the following actions:
      • Connect the deployable to a CI in the CMDB: Select the cmdb_ci and then select Next.
      • Create a CI to connect to: Select New, define the CI, and then select Next.
      The Review page opens.
    5. Click Next to view the list of deployables on the Edit deployables tab.

      Choose how to create the new CDM application

    What to do next

    The application is not yet structured to accept config data, so the next step is to add the data structure. See Add the nodes that will contain config data to a new CDM application.
