What it is and what it does
Neutron-lib is a shared library within the OpenStack Neutron networking ecosystem that extracts common code, constants, validators, and utilities used across Neutron plugins and related projects. It exists to reduce duplication and provide a stable, versioned interface for code that multiple Neutron components depend on.
The library is built on top of Oslo libraries (oslo.config, oslo.db, oslo.policy, etc.) and other OpenStack infrastructure components, and is primarily consumed by Neutron plugins, agents, and related OpenStack networking services. It is not a general-purpose networking library, but rather an internal abstraction layer for the OpenStack Neutron project itself.
Use it for
- Developing or extending OpenStack Neutron plugins that need access to shared constants, validators, and common abstractions.
- Building Neutron agents or services that require standardized configuration, logging, and policy handling via Oslo libraries.
- Integrating with OpenStack deployments where Neutron plugin code needs a stable, versioned set of shared utilities.
- Accessing OpenStack-specific networking constants and data models used across Neutron components.
