Overview of the Fuel bootstrap builder

Overview of the Fuel bootstrap builder

The bootstrap generator creates bootstrap images for the Fuel Master node that Fuel will use to boot the Fuel Slave nodes. The bootstrap generator uses default configurations, however, you can modify these settings.

You can customize a Fuel bootstrap image using one of the following options:

  • Set additional packages for the installation.
  • Copy custom files into the root bootstrap.
  • Run a user script at the bootstrap file system during the image creation.

You can configure Fuel bootstrap images using the fuel-bootstrap command:

usage: fuel-bootstrap [--version] [-v] [--log-file <LOG_FILE>] [-q] [-h]
                      [--debug] [--config <CONFIG_FILE>]
