Usage: ${0##*/} [ options ] arch release bucket
import a cloud image to your local cloud.
Image is downloaded from Ubuntu cloud-images site and published
to the cloud configured.
options:
--save-downloaded save the downloaded image in '.'
-q | --quiet be quiet, only output the AMI id registered
--disk use the disk image (default is partition)
--stream stream: 'released' or 'daily' (default: released)
the following options pass through to cloud-publish-tarball
or cloud-publish-image:
-l|--add-launch ID : ID can be "all", or "none", or numerical ID
--allow-existing : if a image is already registered
simply report as if work was done
--hook-img EXE : invoke executable 'EXE' with full path to
downloaded disk image file
-o|--output <file> : write registered id and manifest to file
--save-downloaded : if the image is a url, save it to '.'
--image-to-raw : convert disk format to raw before publishing
-l | --use-loader : use the loader kernel rather than linux kernel
-k | --kernel k : use previously registered kernel with id 'k'
specify 'none' for no kernel
-K | --kernel-file f : bundle, upload, use file 'f' as kernel
-r | --ramdisk r : use previously registered ramdisk with id 'r'
specify 'none' for no ramdisk
-R | --ramdisk-file f : bundle, upload, use file 'f' as ramdisk
--resize s : resize the partition image before uploading
's' must be valid input to cloud-resize-image
-B | --block-device-mapping m : specify block device mapping in bundle
