Used to control the use and type of token binding. Can be set to: “disabled” to not check token binding. “permissive” (default) to validate binding information if the bind type is of a form known to the server and ignore it if not. “strict” like “permissive” but if the bind type is unknown the token will be rejected. “required” any form of token binding is needed to be allowed.

- service_token_roles¶

- heartbeat_in_pthread¶
- Type:
boolean
- Default:
False
(DEPRECATED) It is recommend not to use this option anymore. Run the health check heartbeat thread through a native python thread by default. If this option is equal to False then the health check heartbeat will inherit the execution model from the parent process. For example if the parent process has monkey patched the stdlib by using eventlet/greenlet then the heartbeat will be run through a green thread. This option should be set to True only for the wsgi services.
Warning
This option is deprecated for removal. Its value may be silently ignored in the future.

Use quorum queues in RabbitMQ (x-queue-type: quorum). The quorum queue is a modern queue type for RabbitMQ implementing a durable, replicated FIFO queue based on the Raft consensus algorithm. It is available as of RabbitMQ 3.8.0. If set this option will conflict with the HA queues (
rabbit_ha_queues
) aka mirrored queues, in other words the HA queues should be disabled. Quorum queues are also durable by default so the amqp_durable_queues option is ignored when this option is enabled.
- rabbit_transient_quorum_queue¶
- Type:

Use quorum queues for transients queues in RabbitMQ. Enabling this option will then make sure those queues are also using quorum kind of rabbit queues, which are HA by default.

Each time a message is redelivered to a consumer, a counter is incremented. Once the redelivery count exceeds the delivery limit the message gets dropped or dead-lettered (if a DLX exchange has been configured) Used only when rabbit_quorum_queue is enabled, Default 0 which means dont set a limit.

- rabbit_transient_queues_ttl¶
- Type:

- Default:

- Minimum Value:
0
Positive integer representing duration in seconds for queue TTL (x-expires). Queues which are unused for the duration of the TTL are automatically deleted. The parameter affects only reply and fanout queues. Setting 0 as value will disable the x-expires. If doing so, make sure you have a rabbitmq policy to delete the queues or you deployment will create an infinite number of queue over time.In case rabbit_stream_fanout is set to True, this option will control data retention policy (x-max-age) for messages in the fanout queue rather then the queue duration itself. So the oldest data in the stream queue will be discarded from it once reaching TTL Setting to 0 will disable x-max-age for stream which make stream grow indefinitely filling up the diskspace
- rabbit_qos_prefetch_count¶

integer
- Default:
0
Specifies the number of messages to prefetch. Setting to zero allows unlimited messages.
- heartbeat_timeout_threshold¶

How often times during the heartbeat_timeout_threshold we check the heartbeat.
- direct_mandatory_flag¶
- Type:
boolean
- Default:
True
(DEPRECATED) Enable/Disable the RabbitMQ mandatory flag for direct send. The direct send is used as reply, so the MessageUndeliverable exception is raised in case the client queue does not exist.MessageUndeliverable exception will be used to loop for a timeout to lets a chance to sender to recover.This flag is deprecated and it will not be possible to deactivate this functionality anymore
Warning
This option is deprecated for removal. Its value may be silently ignored in the future.
- Reason:
Mandatory flag no longer deactivable.

Should we use consistant queue names or random ones
- hostname¶
- Type:
string
- Default:
node1.example.com
This option has a sample default set, which means that its actual default value may vary from the one documented above.
Hostname used by queue manager. Defaults to the value returned by socket.gethostname().

- Type:
string
- Default:
nova-api
This option has a sample default set, which means that its actual default value may vary from the one documented above.
Process name used by queue manager
- rabbit_stream_fanout¶
- Type:
boolean
- Default:
False
Use stream queues in RabbitMQ (x-queue-type: stream). Streams are a new persistent and replicated data structure (“queue type”) in RabbitMQ which models an append-only log with non-destructive consumer semantics. It is available as of RabbitMQ 3.9.0. If set this option will replace all fanout queues with only one stream queue.
oslo_policy¶
- enforce_scope¶
- Type:
boolean
- Default:
True
This option controls whether or not to enforce scope when evaluating policies. If
True
, the scope of the token used in the request is compared to thescope_types
of the policy being enforced. If the scopes do not match, anInvalidScope
exception will be raised. IfFalse
, a message will be logged informing operators that policies are being invoked with mismatching scope.Warning
This option is deprecated for removal. Its value may be silently ignored in the future.
- Reason:
This configuration was added temporarily to facilitate a smooth transition to the new RBAC. OpenStack will always enforce scope checks. This configuration option is deprecated and will be removed in the 2025.2 cycle.
- enforce_new_defaults¶
- Type:
boolean
- Default:
True
This option controls whether or not to use old deprecated defaults when evaluating policies. If
True
, the old deprecated defaults are not going to be evaluated. This means if any existing token is allowed for old defaults but is disallowed for new defaults, it will be disallowed. It is encouraged to enable this flag along with theenforce_scope
flag so that you can get the benefits of new defaults andscope_type
together. IfFalse
, the deprecated policy check string is logically OR’d with the new policy check string, allowing for a graceful upgrade experience between releases with new policies, which is the default behavior.
