|
SPECIFYING IMAGE METADATA
|
|
===============================================================================
|
|
|
|
All field/value pairs are converted into a mapping that is passed
|
|
to Glance that represents the metadata for an image.
|
|
|
|
Field names of note:
|
|
|
|
id Optional. If not specified, an image identifier will be
|
|
automatically assigned.
|
|
name Optional. A name for the image.
|
|
size Optional. Should be size in bytes of the image if
|
|
specified.
|
|
is_public Optional. If specified, interpreted as a boolean value
|
|
and sets or unsets the image's availability to the public.
|
|
The default value is False.
|
|
protected Optional. If specified, interpreted as a boolean value
|
|
and enables or disables deletion protection.
|
|
The default value is False.
|
|
min_disk Optional. The minimum disk size in gigabytes required to
|
|
boot the image. If unspecified, this value defaults to 0
|
|
(no minimum).
|
|
min_ram Optional. The minimum ram size in megabytes required to
|
|
boot the image. If unspecified, this value defaults to 0
|
|
(no minimum).
|
|
disk_format Required. If unspecified and container_format is specified
|
|
as 'ami', 'ari' or 'aki', disk_format will default to the
|
|
container_format value. Possible values are 'ami', 'ari',
|
|
'aki', 'vhd', 'vmk', 'raw', 'qcow2' and 'vdi'.
|
|
container_format Required. If unspecified and disk_format is specified as
|
|
'ami', 'ari' or 'aki', container_format will default to the
|
|
disk_format value. Possible values are 'ami', 'ari', 'aki',
|
|
'bare' and 'ovf'.
|
|
location Optional. When specified, should be a readable location
|
|
in the form of a URI: $STORE://LOCATION. For example, if
|
|
the image data is stored in a file on the local
|
|
filesystem at /usr/share/images/some.image.tar.gz
|
|
you would specify:
|
|
location=file:///usr/share/images/some.image.tar.gz
|
|
copy_from Optional. An external location (HTTP, S3 or Swift URI) to
|
|
copy image content from. For example, if the image data is
|
|
stored as an object called fedora16 in an S3 bucket named
|
|
images, you would specify (with the approriate access and
|
|
secret keys):
|
|
copy_from=s3://akey:skey@s3.amazonaws.com/images/fedora16
|
|
|
|
Any other field names are considered to be custom properties so be careful
|
|
to spell field names correctly.
|
|
|
|
STREAMING IMAGE DATA
|
|
===============================================================================
|
|
|
|
If the location field is not specified, you can stream an image file on
|
|
the command line using standard redirection. For example:
|
|
|
|
%(prog)s add name="Ubuntu 10.04 LTS 5GB" < /tmp/images/myimage.tar.gz
|
|
|
|
EXAMPLES
|
|
===============================================================================
|
|
|
|
%(prog)s add name="My Image" disk_format=raw container_format=ovf \
|
|
location=http://images.ubuntu.org/images/lucid-10.04-i686.iso \
|
|
distro="Ubuntu 10.04 LTS"
|
|
|
|
