We hit the same issue with Liberty. However there is a fix for heat to use keystone session from context in client plugin instead of username,password. https://github.com/openstack/heat/commit/cd125f328e3e4e9f517278b04347515eba380d5a This fix is only for Newton. When try in Liberty: def _create(self): endpoint_type = self._get_client_option('nova', 'endpoint_type') extensions = nc.discover_extensions('2') args = { 'session': self.context.keystone_session, 'extensions': extensions, 'interface': endpoint_type, 'service_type': self.COMPUTE, 'http_log_debug': self._get_client_option('nova', 'http_log_debug') } We got error: 2016-09-22 16:27:18.355 26510 ERROR heat.engine.stack File "/usr/lib/python2.7/dist-packages/heat/engine/clients/os/nova.py", line 95, in _create 2016-09-22 16:27:18.355 26510 ERROR heat.engine.stack 'session': self.context.keystone_session, 2016-09-22 16:27:18.355 26510 ERROR heat.engine.stack AttributeError: 'RequestContext' object has no attribute 'keystone_session' When we tried put there "'session': self._keystone_session," instead: 2016-09-22 16:28:18.528 26861 ERROR heat.engine.stack File "/usr/lib/python2.7/dist-packages/keystoneclient/session.py", line 596, in _auth_required 2016-09-22 16:28:18.528 26861 ERROR heat.engine.stack raise exceptions.MissingAuthPlugin(msg) 2016-09-22 16:28:18.528 26861 ERROR heat.engine.stack MissingAuthPlugin: An auth plugin is required to determine endpoint URL -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1534655 Title: Autoscaling auth failure in OpenStack Kilo 2015.1.2 To manage notifications about this bug go to: https://bugs.launchpad.net/heat/+bug/1534655/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
