Get the name of celery worker from inside a celery task?

celery, celery-task, python

Solution

Use the `celeryd_after_setup` signal to capture the worker name like this:

from celery.signals import celeryd_after_setup

@celeryd_after_setup.connect
def capture_worker_name(sender, instance, **kwargs):
    os.environ["WORKER_NAME"] = '{0}'.format(sender)

Problem

I'd like a celery task to be able to get the name of the worker executing it, for logging purposes. I need to handle this from within the task, rather than querying the broker directly. Is there a way to do this? I'm using celery with RabbitMQ, if that matters.
