Overview

Class: mistral

Mistral base package & configuration

Parameters

package_ensure

(Optional) Ensure state for package. Defaults to ‘present’.

os_actions_endpoint_type

(optional) Type of endpoint in identity service catalog to use for communication with OpenStack services Defaults to $::os_service_default

default_transport_url

(optional) A URL representing the messaging driver to use and its full configuration. Transport URLs take the form:

transport://user:pass@host1:port[,hostN:portN]/virtual_host

Defaults to $::os_service_default

notification_transport_url

(optional) A URL representing the messaging driver to use for notifications and its full configuration. Transport URLs take the form:

transport://user:pass@host1:port[,hostN:portN]/virtual_host

Defaults to $::os_service_default

notification_driver

(optional) Driver or drivers to handle sending notifications. Value can be a string or a list. Defaults to $::os_service_default

notification_topics

(optional) AMQP topic used for OpenStack notifications Defaults to $::os_service_default

rabbit_ha_queues

(optional) Use HA queues in RabbitMQ (x-ha-policy: all). Defaults to $::os_service_default

rabbit_heartbeat_timeout_threshold

(optional) Number of seconds after which the RabbitMQ broker is considered down if the heartbeat keepalive fails. Any value >0 enables heartbeats. Heartbeating helps to ensure the TCP connection to RabbitMQ isn’t silently closed, resulting in missed or lost messages from the queue. (Requires kombu >= 3.0.7 and amqp >= 1.4.0) Defaults to $::os_service_default

rabbit_heartbeat_rate

(optional) How often during the rabbit_heartbeat_timeout_threshold period to check the heartbeat on RabbitMQ connection. (i.e. rabbit_heartbeat_rate=2 when rabbit_heartbeat_timeout_threshold=60, the heartbeat will be checked every 30 seconds. Defaults to $::os_service_default

rabbit_heartbeat_in_pthread

(Optional) EXPERIMENTAL: Run the health check heartbeat thread through a native python thread. By default if this option isn’t provided the health check heartbeat will inherit the execution model from the parent process. By example if the parent process have monkey patched the stdlib by using eventlet/greenlet then the heartbeat will be run through a green thread. Defaults to $::os_service_default

rabbit_use_ssl

(optional) Connect over SSL for RabbitMQ Defaults to $::os_service_default

report_interval

(optional) Interval, in seconds, between nodes reporting state to datastore (integer value). Defaults to $::os_service_default

service_down_time

(optional) Maximum time since last check-in for a service to be considered up (integer value). Defaults to $::os_service_default

kombu_failover_strategy

(Optional) Determines how the next RabbitMQ node is chosen in case the one we are currently connected to becomes unavailable. Takes effect only if more than one RabbitMQ node is provided in config. (string value) Defaults to $::os_service_default

kombu_ssl_ca_certs

(optional) SSL certification authority file (valid only if SSL enabled). Defaults to $::os_service_default

kombu_ssl_certfile

(optional) SSL cert file (valid only if SSL enabled). Defaults to $::os_service_default

kombu_ssl_keyfile

(optional) SSL key file (valid only if SSL enabled). Defaults to $::os_service_default

kombu_ssl_version

(optional) SSL version to use (valid only if SSL enabled). Valid values are TLSv1, SSLv23 and SSLv3. SSLv2 may be available on some distributions. Defaults to $::os_service_default

kombu_reconnect_delay

(optional) How long to wait before reconnecting in response to an AMQP consumer cancel notification. Defaults to $::os_service_default

amqp_durable_queues

(optional)Use durable queues in amqp. Defaults to $::os_service_default

control_exchange

(Optional) The default exchange under which topics are scoped. May be overridden by an exchange name specified in the transport_url option. Defaults to $::os_service_default

rpc_response_timeout

(Optional) Seconds to wait for a response from a call. (integer value) Defaults to $::os_service_default

purge_config

(optional) Whether to set only the specified config options in the mistral config. Defaults to false.

sync_db

(Optional) Enable dbsync Defaults to true.

max_missed_heartbeats

(Optional) The maximum amount of missed heartbeats to be allowed. If set to 0 then this feature is disabled. See check_interval for more details. Defaults to $::os_service_default

check_interval

(Optional) How often (in seconds) action executions are checked. For example when check_interval is 10, check action executions every 10 seconds. When the checker runs it will transit all running action executions to error if the last heartbeat received is older than 10 * max_missed_heartbeats seconds. If set to 0 then this feature is disabled. Defaults to $::os_service_default

first_heartbeat_timeout

(Optional) The first heartbeat is handled differently, to provide a grace period in case there is no available executor to handle the action execution. For example when first_heartbeat_timeout = 3600, wait 3600 seconds before closing the action executions that never received a heartbeat. Defaults to $::os_service_default
