This tag is part of the assert category of tags, which are assertions made by the project team themselves about the maturity of their deliverables.

The “assert:supports-standalone” tag asserts that the service can be operated without requiring other OpenStack services, if the operator so chooses.

Application to current deliverables


No projects are using supports-standalone, yet.


While OpenStack services are designed to work well together to manage the datacenter as a whole, some services can be operated independently of each other for specific use cases and requirements. Operators need to know which services these are in order to consider their adoption.


  • The core functionality of the service is not affected by being operated without other OpenStack services and limitations are clearly documented.

  • The service either supports another form of authentication separate from Keystone, or no authentication in the case of a single tenant environment.

  • The project tests and gates this deployment strategy.
