type: bool
default: 'no'
login_host:
description:
- rabbitMQ host for connection
default: localhost
login_port:
description:

default: 15672
vhost:
description:
- rabbitMQ virtual host
default: "/"
durable:
description:
- whether queue is durable or not
type: bool
default: 'yes'
auto_delete:
description:
- if the queue should delete itself after all queues/queues unbound from it
type: bool
default: 'no'
message_ttl:
description:
- How long a message can live in queue before it is discarded (milliseconds)
default: forever
auto_expires:
description:
- How long a queue can be unused before it is automatically deleted (milliseconds)
default: forever

description:
- Maximum number of priority levels for the queue to support.
- If not set, the queue will not support message priorities.
- Larger numbers indicate higher priority.
