Create a tar ball with the contents of the / and /usr partitions to be used as follows with systemd-nspawn (via machinectl): machinectl import-tar flatcar-container.tar.gz flatcar-container machinectl start flatcar-container machinectl shell flatcar-container or with docker by converting it to an OCI image: docker import -c "CMD /bin/bash" flatcar-container.tar.gz flatcar-container Since the new "prodtar" command relies on the results of the "prod" command, it bundles it so that "prod prodtar" and "prodtar" is the same.

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.
