 | |
| 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.
