So, in the policy language, the previous check in -list-of-lists becomes:: - - role:admin or (project_id:%(project_id)s and role:projectadmin) - -The policy language also has the "not" operator, allowing a richer -policy rule:: - - project_id:%(project_id)s and not role:dunce - -Attributes sent along with API calls can be used by the policy engine -(on the right side of the expression), by using the following syntax:: - - :%(user.id)s - -Contextual attributes of objects identified by their IDs are loaded -from the database. They are also available to the policy engine and -can be checked through the `target` keyword:: - - :%(target.role.name)s - -Finally, two special policy checks should be mentioned; the policy -check "@" will always accept an access, and the policy check "!" will -always reject an access. (Note that if a rule is either the empty -list ("[]") or the empty string, this is equivalent to the "@" policy -check.) Of these, the "!" policy check is probably the most useful, -as it allows particular rules to be explicitly disabled. -""" - -import abc -import ast -import copy -import logging -import os -import re - -from oslo.config import cfg -from oslo.serialization import jsonutils -import six -import six.moves.urllib.parse as urlparse -import six.moves.urllib.request as urlrequest - -from ceilometer.openstack.common import fileutils -from ceilometer.openstack.common._i18n import _, _LE, _LI - - -policy_opts = [ - cfg.StrOpt('policy_file', - default='policy.json', - help=_('The JSON file that defines policies.')), - cfg.StrOpt('policy_default_rule', - default='default', - help=_('Default rule.
