Look at
https://github.com/rackspace/stacktach/blob/master/worker.py
(ignore the _process() call, just look at how the queue listeners are
set up)
my worker_conf.py looks something like
DEPLOYMENTS = [
dict(
tenant_id=1,
url='http://stacktach.example.com',
rabbit_host="10.0.0.1",
rabbit_port=5672,
rabbit_userid="nova-staging",
rabbit_password="password",
rabbit_virtual_host="staging"),
dict(
tenant_id=2,
url='http://stacktach.example.com',
rabbit_host="10.99.0.1",
rabbit_port=5672,
rabbit_userid="nova",
rabbit_password="password",
rabbit_virtual_host="production"),
]
Or the queue listeners in
https://github.com/Cerberus98/yagi
Hope it helps!
