Celery usage

Jumpserver use celery to run task async. Using redis as the broker, so you should run a redis instance

Run redis

$ yum -y install redis 

or

$ docker run -name jumpserver-redis -d -p 6379:6379 redis redis-server

Write tasks in app_name/tasks.py

ops/tasks.py

from __future__ import absolute_import

import time
from celery import shared_task
from common import celery_app


@shared_task
def longtime_add(x, y):
    print 'long time task begins'
    # sleep 5 seconds
    time.sleep(5)
    print 'long time task finished'
    return x + y
    

@celery_app.task(name='hello-world')
def hello():
    print 'hello world!'
  

Run celery in development

$ cd apps
$ celery -A common worker -l info 

Test using task

$ ./manage.py shell
>>> from ops.tasks import longtime_add
>>> res = longtime_add.delay(1, 2)
>>> res.get()
