Public bug reported: Keystone supports notifications via oslo.messaging. Included with oslo.messaging notifications is the ability to emit messages using AMQP (e.g., rabbitmq).
Keystone uses notification extensively in its API to signal when resources are modified (creating, updating, or deleting users, projects, domains, role assignments, etc). If keystone is configured to use AMQP for notifications but the AMQP server isn't reachable, keystone-manage will hang. Steps to reproduce: 1. install a fresh devstack with keystone and rabbit as enabled services 2. configure keystone to emit messages using the messagingv2 driver and put a typo in the connection string [oslo_messaging_notifications] transport_url = rabbit://stackrabbit:[email protected]:5672/ driver = messagingv2 3. restart keystone 4. run keystone-manage bootstrap --bootstrap-password $password You'd expect keystone-manage to handle connections with rabbit gracefully but it hangs. https://pasted.tech/pastes/2a87e13e2e9e7323a93a14419ef6ebf55881621e.raw ** Affects: keystone Importance: Undecided Status: New ** Description changed: Keystone supports notifications via oslo.messaging.
