This script is used to build a CoreOS image. CoreOS comes in many
|
|
different forms. This scripts can be used to build the following:
|
|
|
|
prod - Production image for CoreOS. This image is for booting (default if no argument is given).
|
|
prodtar - Production container tar ball (implies prod). This can e.g. be used to run the Flatcar production image as a container (run machinectl import-tar or docker import).
|
|
container - Developer image with single filesystem, bootable by nspawn.
|
|
|
|
Examples:
|
|
|
|
build_image --board=<board> [prod] [prodtar] [container] - builds developer and production images/tars.
