Usage
-----

To run Flower, you need to provide the broker URL ::

    $ celery --broker=amqp://guest:guest@localhost:5672// flower

Or use the configuration of `celery application <https://docs.celeryq.dev/en/stable/userguide/application.html>`_  ::

    $ celery -A tasks.app flower

By default, flower runs on port 5555, which can be modified with the `port` option ::

    $ celery -A tasks.app flower --port=5001

You can also run Flower using the docker image ::

    $ docker run -v examples:/data -p 5555:5555 mher/flower celery --app=tasks.app flower

In this example, Flower is using the `tasks.app` defined in the `examples/tasks.py <https://github.com/mher/flower/blob/master/examples/tasks.py>`_ file

API
---

Flower API enables to manage the cluster via HTTP `REST API`.

For example you can restart worker's pool by: ::

    $ curl -X POST http://localhost:5555/api/worker/pool/restart/myworker

Or call a task by: ::

    $ curl -X POST -d '{"args":[1,2]}' http://localhost:5555/api/task/async-apply/tasks.add

Or terminate executing task by: ::

    $ curl -X POST -d 'terminate=True' http://localhost:5555/api/task/revoke/8a4da87b-e12b-4547-b89a-e92e4d1f8efd
