Celery workers do not respect queue

[tino]

I run a setup as I described here: http://stackoverflow.com/questions/28456500/celery-how-to-separate-different-environments-with-different-workers

$ celery -A website.celery list bindings
Queue                        Exchange                     Routing Key
----------------             ----------------             ----------------
myserver_development         celery                       celery
myserver                     celery                       celery
myserver_staging             celery                       celery

When I trigger a task in the development environment (with CELERY_DEFAULT_QUEUE = 'myserver_development'), I see the task being executed in all three queues.

[ask]

You have to set all of CELERY_DEFAULT_QUEUE, CELERY_DEFAULT_EXCHANGE and CELERY_DEFAULT_ROUTING_KEY. Otherwise you will end up with three queues all bound to the same exchange and routing key.

Or use the method here which will set it up explicitly:
