Launch the server and open http://localhost:5555:

$ flower --port=5555

Launch from celery:

$ celery flower -A proj --address= --port=5555

Launch using docker:

$ docker run -p 5555:5555 mher/flower

Launch with unix socket file:

$ flower --unix-socket=/tmp/flower.sock

Broker URL and other configuration options can be passed through the standard Celery options:

Flower API enables to manage the cluster via REST API, call tasks and receive task events in real-time via WebSockets.

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

Or receive task completion events in real-time:

var ws = new WebSocket("ws://localhost:5555/api/task/events/task-succeeded/");
ws.onmessage = function (event) {
