Roles
=====
OpenStack services typically determine whether a user's API request should be
allowed using Role Based Access Control (RBAC). For OpenStack this means the
service compares the roles that user has on the project (as indicated by the
roles in the token), against the roles required for the API in question
(as defined in the service's policy file). A user obtains roles on a project by
having these assigned to them via the Identity service API.
Roles must initially be created as entities via the Identity services API and,
once created, can then be assigned. You can assign roles to a user or group on a
project, including projects owned by other domains. You can also assign roles
to a user or group on a domain, although this is only currently relevant for
using a domain scoped token to execute domain-level Identity service API
requests.
The creation, checking and deletion of role assignments is done with each of
the attributes being specified in the URL. For example to assign a role to a
user on a project::
PUT /v3/projects/{project_id}/users/{user_id}/roles/{role_id}
You can also list roles assigned to a specified domain, project, or user using
this form of API, however a more generalized API for list assignments is
provided where query parameters are used to filter the set of assignments
returned in the collection. For example:
- List role assignments for the specified user::
GET /role_assignments?user.id={user_id}
- List role assignments for the specified project::
GET /role_assignments?scope.project.id={project_id}
Since Identity API v3.6, you can also list all role assignments within a tree of projects,
for example the following would list all role assignments for a specified
project and its sub-projects::
GET /role_assignments?scope.project.id={project_id}&include_subtree=true
If you specify ``include_subtree=true``, you must also specify the
``scope.project.id``. Otherwise, this call returns the ``Bad Request (400)``
response code.
Each role assignment entity in the collection contains a link to
the assignment that created the entity.
As mentioned earlier, role assignments can be made to a user or a group on a
particular project or domain. A user who is a member of a group that has a
role assignment, will also be treated as having that role assignment by virtue
of their group membership. The *effective* role assignments of a user (on a
given project or domain) therefore consists of any direct assignments they have,
plus any they gain by virtue of membership of groups that also have assignments
on the given project or domain. This set of effective role assignments is what
is placed in the token for reference by services wishing to check policy. You
can list the effective role assignments using the ``effective`` query parameter
at the user, project, and domain level:
- Determine what a user can actually do::
GET /role_assignments?user.id={user_id}&effective
- Get the equivalent set of role assignments that are included in a
project-scoped token response::
GET /role_assignments?user.id={user_id}&scope.project.id={project_id}&effective
When listing in effective mode, since the group assignments have been
effectively expanded out into assignments for each user, the group role
assignment entities themselves are not returned in the collection. However,
in the response, the ``links`` entity section for each assignment gained by
virtue of group membership will contain a URL that enables access to the
membership of the group.
By default only the IDs of entities are returned in collections from the
role_assignment API calls. The names of entities may also be returned,
in addition to the IDs, by using the ``include_names`` query parameter
on any of these calls, for example:
- List role assignments including names::
GET /role_assignments?include_names
