OpenStack Image Storage (glance) is 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.
Image services include discovering, registering, and retrieving virtual machine images. Glance has a RESTful API that allows querying of VM image metadata as well as retrieval of the actual image.
For more details on the service see the OpenStack Glance documentation.
Whilst this chapter is currently sparse on specific guidance, it is expected that standard hardening practices will be followed. This section will be expanded with relevant information.
