Common and Misc Libraries
Libraries common throughout Cinder or just ones that haven’t been categorized
very well yet.
The cinder.adminclient Module
The cinder.context Module
RequestContext: context for requests that persist through all of cinder.
-
class RequestContext(user_id, project_id, is_admin=None, read_deleted='no', roles=None, project_name=None, remote_address=None, timestamp=None, request_id=None, auth_token=None, overwrite=True, quota_class=None, service_catalog=None, domain=None, user_domain=None, project_domain=None, **kwargs)
Bases: oslo_context.context.RequestContext
Security context and request information.
Represents the user taking a given action within the system.
-
deepcopy()
-
elevated(read_deleted=None, overwrite=False)
Return a version of this context with admin flag set.
-
classmethod from_dict(values)
-
project_id
-
read_deleted
-
to_dict()
-
user_id
-
get_admin_context(read_deleted='no')
-
get_internal_tenant_context()
Build and return the Cinder internal tenant context object
This request context will only work for internal Cinder operations. It will
not be able to make requests to remote services. To do so it will need to
use the keystone client to get an auth_token.
The cinder.exception Module
Cinder base exception handling.
Includes decorator for re-raising Cinder-type exceptions.
SHOULD include dedicated exception logging.
