image-builder-pre-builder-flexiflow¶

Utilizes flexiflow to expand the image-builder content dynamically.

This stage utilizes the Flexiflow content pack to allow image builds that can dynamically inject new tasks to customize the OS/image before cleanup.

To utilize this, please review the Flexiflow content for more complete details. Basic usage:

• set the Param image-builder/pre-builder-flexiflow as an Array of tasks to inject in place of this stage

Example:

image-builder/pre-builder-flexiflow:
  - repository-add
  - install-my-packages
  - repository-remove

In our theoretical example above, we have 3 tasks. The first should add a new repository to the installed system (for example EPEL). The second would install some packages that are contained in the example repository. The third then removes the example repository from the sysmem - so the final installed system is in a clean state without those repos.
