Table: 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	Select the Image Location option to specify the image location using its URL. Select the Image File option to upload an image from your local disk.
Format	Image format (for example, qcow2).
Architecture	Image architecture. We support 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 uploaded successfully, its status is changed to active, which indicates that the image is available for use. The Image service can handle large images that take a long time to upload, possibly longer than the lifetime of the Identity service token which was used when the upload was initiated. 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.

Note: 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 listing, see Image Configuration Parameters.

Purge Your Deleted Image Data

Information about an image is kept in the OpenStack Image Service database even after the image has been deleted. As a consequence, the database can grow in size over time and become slow to use and hard to upgrade. Contact the Support team for help in removing deleted images.
