表1.1 Image options
| Field | Notes |
|---|---|
| Name | Name for the image. The name must be unique within the project. |
| Description | Brief description to identify the image. |
| Image Source | Image source: Image Location or Image File. Based on your selection, the next field is displayed. |
| Image Location or Image File |
|
| Format | Image format (for example, qcow2). |
| Architecture | Image architecture. For example, use i686 for a 32-bit architecture or x86_64 for a 64-bit architecture. |
| Minimum Disk (GB) | Minimum disk size required to boot the image. If this field is not specified, the default value is 0 (no minimum). |
| Minimum RAM (MB) | Minimum memory size required to boot the image. If this field is not specified, the default value is 0 (no minimum). |
| Public | If selected, makes the image public to all users with access to the project. |
| Protected | If selected, ensures only users with specific permissions can delete this image. |
When the image has been successfully uploaded, its status is changed to active, which indicates that the image is available for use. The Image service can handle even large images that take a long time to upload, longer than the lifetime of the Identity service token which was used to initiate the upload. This is due to the fact that the Image service first creates a trust with the Identity service so that a new token can be obtained and used when the upload is complete and the status of the image is to be updated.
You can also use the glance image-create command with the --property option to upload an image. More values are available on the command line. For a complete list of available metadata properties, see Image Configuration Parameters.
