quay.io/tinkerbell/actions/image2disk:latest
This action will stream a remote disk image (raw) to a block device, and
is mainly used to write cloud images to a disk. It is recommended to use the qemu-img
tool to convert disk images into raw, it is also possible to compress the raw images
with tar+gzip to prevent wasted disk space
The below example will stream a raw ubuntu cloud image (converted by qemu-img) and write
it to the block storage disk /dev/sda
. The raw image is uncompressed in this example.
