author: OpenStack Ansible SIG
description:
    - Add or remove access to OpenStack compute flavor

    description:
      - Name or ID of the compute flavor.
    required: true
    type: str
  project:
    description:
      - ID or Name of project to grant.
      - Allow I(project) to access private flavor (name or ID).
    type: str
    required: true
  project_domain:
     description:
       - Domain the project belongs to (name or ID).
       - This can be used in case collisions between project names exist.

    description:
      - Indicate whether project should have access to compute flavor or not.

notes:
    - A compute flavor must be private to manage project access.
