# glance --os-image-api-version 1 help image-create
usage: glance image-create [--id <IMAGE_ID>] [--name <NAME>] [--store <STORE>]
[--disk-format <DISK_FORMAT>]
[--container-format <CONTAINER_FORMAT>]
[--owner <TENANT_ID>] [--size <SIZE>]
[--min-disk <DISK_GB>] [--min-ram <DISK_RAM>]
[--location <IMAGE_URL>] [--file <FILE>]
[--checksum <CHECKSUM>] [--copy-from <IMAGE_URL>]
[--is-public {True,False}]
[--is-protected {True,False}]
[--property <key=value>] [--human-readable]
[--progress]
Optional arguments:
--id <IMAGE_ID> ID of image to reserve.
--name <NAME> Name of image.
--store <STORE> Store to upload image to.
--disk-format <DISK_FORMAT>
Disk format of image. Acceptable formats: ami, ari,
aki, vhd, vmdk, raw, qcow2, vdi, and iso.
--container-format <CONTAINER_FORMAT>
Container format of image. Acceptable formats: ami,
ari, aki, bare, and ovf.
--owner <TENANT_ID> Tenant who should own image.
--size <SIZE> Size of image data (in bytes). Only used with '--
location' and '--copy_from'.
--min-disk <DISK_GB> Minimum size of disk needed to boot image (in
gigabytes).
--min-ram <DISK_RAM> Minimum amount of ram needed to boot image (in
megabytes).
--location <IMAGE_URL>
URL where the data for this image already resides. For
example, if the image data is stored in swift, you
could specify 'swift+http://tenant%3Aaccount:key@auth_
url/v2.0/container/obj'. (Note: '%3A' is ':' URL
encoded.)
--file <FILE> Local file that contains disk image to be uploaded
during creation. Alternatively, images can be passed
to the client via stdin.
--checksum <CHECKSUM>
Hash of image data used Glance can use for
verification. Provide a md5 checksum here.
--copy-from <IMAGE_URL>
Similar to '--location' in usage, but this indicates
that the Glance server should immediately copy the
data and store it in its configured image store.
--is-public {True,False}
Make image accessible to the public.
--is-protected {True,False}
Prevent image from being deleted.
--property <key=value>
Arbitrary property to associate with image. May be
used multiple times.
--human-readable Print image size in a human-friendly format.
--progress Show upload progress bar.
