Acceptable values are 0, <port>, and <start>:<end>, where 0 results in listening on a random tcp port number; <port> results in listening on the specified port number (and not enabling backdoor if that port is in use); and <start>:<end> results in listening on the smallest unused port number within the specified range of port numbers. The chosen port is displayed in the service’s log file.

<None>
Enable eventlet backdoor, using the provided path as a unix socket that can receive connections. This option is mutually exclusive with ‘backdoor_port’ in that only one should be provided.

True
If False, closes the client socket connection explicitly.
- client_socket_timeout¶

In order to prevent excessive effort spent validating tokens, the middleware caches previously-seen tokens for a configurable duration (in seconds). Set to -1 to disable caching completely.
- memcache_security_strategy¶

string
- Default:
None
- Valid Values:
None, MAC, ENCRYPT
(Optional) If defined, indicate whether token data should be authenticated or authenticated and encrypted. If MAC, token data is authenticated (with HMAC) in the cache. If ENCRYPT, token data is encrypted and authenticated in the cache. If the value is not one of these options or empty, auth_token will raise an exception on initialization.

- enforce_token_bind¶
- Type:
string
- Default:
permissive
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. Finally the name of a binding method that must be present in tokens.
- service_token_roles¶
- Type:
list

['service']
A choice of roles that must be present in a service token. Service tokens are allowed to request that an expired token can be used and so this check should tightly control that only actual services should be sending this token.

In some configurations it may be preferable to use the virtual hostname instead, for example if the server uses the Server Name Indication TLS extension (rfc6066) to provide a certificate per virtual host.

- heartbeat_in_pthread¶
- Type:

- 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.

Try to use HA queues in RabbitMQ (x-ha-policy: all). If you change this option, you must wipe the RabbitMQ database.

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¶

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.

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.

- heartbeat_rate¶
- Type:
integer
- Default:
3
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.
- enable_cancel_on_failover¶
- Type:
boolean
- Default:
False
Enable x-cancel-on-ha-failover flag so that rabbitmq server will cancel and notify consumerswhen queue is down
- use_queue_manager¶
- Type:
boolean
- Default:
False
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().
- processname¶
- Type:
string
- Default:
sphinx-build
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_middleware¶
- enable_proxy_headers_parsing¶
- Type:
boolean
- Default:
False
Whether the application is behind a proxy or not. This determines if the middleware should parse the headers or not.
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.
- policy_file¶
- Type:

A user who triggers the profiling via the REST API has to set one of these keys in the headers of the REST API call to include profiling results of this node for this particular project.
Both “enabled” flag and “hmac_keys” config options should be set to enable profiling. Also, to generate correct profiling information across all services at least one key needs to be consistent between OpenStack projects. This ensures it can be used from client side to generate the trace, containing information from all possible resources.
