Create a Blueprint

Using the Image Builder web console page, Cockpit administrators can create a blueprint specification for building an image.

What Do You Need?

  • The Cockpit web console must be installed and accessible.

    For further details, see these topics: Install and Enable Cockpit and Log in to the Cockpit Web Console.

  • Image Builder packages must be installed on the host system. The cockpit-composer add-on application must be configured.

    For details, see Install and Configure Cockpit-Composer

  • All Image Builder blueprints require a user-defined name. All other blueprint properties such as add on packages and customization properties are optional.
  • Administrator privileges.

Steps

Using the Cockpit web console, follow these steps to create an Image Builder blueprint.

  1. In the Cockpit navigation pane, click Image Builder, and then on the Image Builder page, click Create Blueprint.
    The Create Blueprint dialog appears.
  2. In the Create Blueprint dialog, define the blueprint specifications as follows:
    1. Details section: In the Name text box, enter a user-defined name for the blueprint. In the Description text box, optionally identify the purpose of the blueprint.
      Click Next to advance to the Packages section
    2. Packages section (optional): In the Available Packages text box, optionally search for the names of the packages you want add to the image. Use the right-arrow-key to move a selected package to the Chosen Package list box.

      Note:

      The entries appearing in the Available Packages text box reflect the default packages included in the Oracle Linux distribution that's installed on the Cockpit host. To list all the add-on packages available, type *.* in the Available packages text box, and then press Enter.

      Click Next to advance to the Customization section.

    3. Customization section (optional): Optionally define system image configuration properties that are typically defined post installation.

      For example, scroll to Users, click Add user to define properties for adding a user to an image.

      For descriptions of each customization component, see Blueprint Customization Components

      Click Next to advance to the Review section.

    4. Review section: Review the specified blueprint specifications and, if acceptable, click Create to compose the blueprint.
      The [user defined] blueprint name page appears. From this page, you can optionally perform any of the following:
      • Click Back to blueprints to return to the Image Builder page listing all available blueprints on the host.
      • Click Edit blueprint to make further modifications to the newly created blueprint. For more details, see Edit Blueprint.
      • Click Create image to generate an image from the newly created blueprint. For more details, see Create an Image From a Blueprint
