Dan Mihai 65385a5bf9 image: custom guest rootfs image file size alignment
The Guest rootfs image file size is aligned up to 128M boundary,
since commmit 2b0d5b2. This change allows users to use a custom
alignment value - e.g., to align up to 2M, users will be able to
specify IMAGE_SIZE_ALIGNMENT_MB=2 for image_builder.sh.

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
