Add upload-to-image command to volume

[Steve Martinelli]

I don't believe we have this functionality to date, cinder has the following command for v1 (not sure about v2):

upload-to-image Upload volume to image service as image.

usage: cinder upload-to-image [--force <True|False>]
                              [--container-format <container-format>]
                              [--disk-format <disk-format>]
                              <volume-id> <image-name>

Upload volume to image service as image.

Positional arguments:
  <volume-id> ID of the volume to upload to an image
  <image-name> Name for created image

Optional arguments:
  --force <True|False> Optional flag to indicate whether to upload a volume
                        even if it's attached to an instance. (Default=False)
  --container-format <container-format>
                        Optional type for container format (Default=bare)
  --disk-format <disk-format>
                        Optional type for disk format (Default=raw)

I killed the cinder component because, the cinder client supports the backup-create where you can create a volume from an image.

[Terry Howe (thowe-g)]

Just to clear the confusion (maybe I'm the only one confused by the scope of this request):

The glance client supports image upload with the --file option or you may pass the image in through stdin. From the help:

usage: glance image-create [--id <IMAGE_ID>] [--name <NAME>] [--store <STORE>]
...
  --file <FILE> Local file that contains disk image to be uploaded
                        during creation. Alternatively, images can be passed
                        to the client via stdin.

[Terry Howe (thowe-g)]

What I meant was cinder create takes an image reference, not backup-create.

[Terry Howe (thowe-g)]

Let me know if I'm missing something here Steve, but the "os volume create" command takes an image to create a volume from an image.

[Terry Howe (thowe-g)]

The only thing I see missing is there is no "os image create" with a --volume option which should map to this upload-to-image command. I would actually access cinder to do the work.

[Steve Martinelli (stevemar)]

Terry, the command would let folks upload a cinder volume to glance, after creation.

[Terry Howe (thowe-g)]

Okay, I'll investigate. Seems like it would be nicer to add the --volume option, but I don't know how that would work crossing from image to volume.
