OpenStack Image Service Store Library
Decision gist · record as of 2026-08-14
Yes, but only if you are developing or deploying Glance or Glare within OpenStack. The library is actively maintained, has no known vulnerabilities, and carries a permissive license. However, the documentation explicitly warns that the API is unstable and unsupported outside those two projects, so do not adopt it for general-purpose image storage abstraction in other applications.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; intended for use within OpenStack deployments, not as a general-purpose library.
- Low install friction with a pure-Python wheel and 12 runtime dependencies from the OpenStack ecosystem.
- Actively maintained with a recent release.

What it is and what it does
Glance Store Library is the storage abstraction layer extracted from OpenStack's Glance image service. It provides a pluggable interface for reading and writing image data to different backend storage systems—local filesystem, object storage, block storage, and others—without coupling Glance or Glare to any single storage implementation.
The library is tightly integrated with the OpenStack ecosystem, depending on oslo configuration, serialization, and concurrency utilities, plus Keystone authentication. It is explicitly documented as having an unstable API and is not intended for use outside Glance and Glare; the core team does not support external adoption. It is most useful as an internal component within an OpenStack deployment or for developers contributing to Glance or Glare itself.
Use it for
- Extend Glance image service to support a new storage backend by implementing the store driver interface.
- Integrate image storage operations into Glare artifact repository within an OpenStack cloud.
- Manage image data persistence across multiple storage backends in a Glance deployment.
- Contribute to or fork Glance/Glare and customize image storage behavior for specific infrastructure needs.
