Generate rootfs hash data during creating the kata rootfs, current kata image only have one partition, we add another partition as hash device to save hash data of rootfs data blocks. Fixes: #6674 Signed-off-by: Wang, Arron <arron.wang@intel.com>
Kata Containers image generation
A Kata Containers disk image is generated using the image_builder.sh script.
This uses a rootfs directory created by the rootfs-builder/rootfs.sh script.
Creating a guest OS image
To create a guest OS image run:
$ sudo ./image_builder.sh path/to/rootfs
Where path/to/rootfs is the directory populated by rootfs.sh.
Note
: If you are building an image from an Alpine rootfs, see the important note here.
Further information
For more information about usage (including how to adjust the size of the image), run:
$ ./image_builder.sh -h
