Welcome to Glance’s documentation!

The Image service (glance) project provides a service where users can upload and discover data assets that are meant to be used with other services. This currently includes images and metadata definitions.

Glance image services include discovering, registering, and retrieving virtual machine (VM) images. Glance has a RESTful API that allows querying of VM image metadata as well as retrieval of the actual image.

Note

The Images API v1 has been DEPRECATED in the Newton release. The migration path is to use the Images API v2 instead of version 1 of the API. The Images API v1 will ultimately be removed, following the OpenStack standard deprecation policy.

VM images made available through Glance can be stored in a variety of locations from simple filesystems to object-storage systems like the OpenStack Swift project.
