socket.error: Zeitüberschreitung (Sellerie & RabbitMQ läuft in Docker-Containern)

Question

Versuch, Celery (mit RabbitMQ) offizielle Docker Container zu bringen.

docker run -d --hostname my-rabbit --name some-rabbit rabbitmq 
docker run --link some-rabbit:rabbit --name some-celery -d celery 

ich das Protokoll überprüft haben, ob alles zu machen ist in Ordnung:

# docker logs some-celery 

[2016-10-20 11:05:50,357: WARNING/MainProcess] /usr/local/lib/python3.5/site-packages/celery/apps/worker.py:161: CDeprecationWarning: 
Starting from version 3.2 Celery will refuse to accept pickle by default. 

The pickle serializer is a security concern as it may give attackers 
the ability to execute any command. It's important to secure 
your broker from unauthorized access when using pickle, so we think 
that enabling pickle should require a deliberate action and not be 
the default choice. 

If you depend on pickle then you should set a setting to disable this 
warning and to be sure that everything will continue working 
when you upgrade to Celery 3.2:: 

    CELERY_ACCEPT_CONTENT = ['pickle', 'json', 'msgpack', 'yaml'] 

You must only enable the serializers that you will actually use.

Nun, ich in Host bin mit tasks.py:

from celery import Celery 

app = Celery('tasks', backend='amqp', broker='amqp://guest:guest@172.17.0.2/') 

@app.task(name='tasks.add') 
def add(x, y): 
    return x + y 

und von der Host-Befehlszeile I Führen Sie Python und erhalten:

>>> from tasks import add

    raise socket.error(last_err)

Ich sah diese Question aber es scheint, als ob der Fehler dort anders ist ..

EDIT: ich die RabbitMQ Container Protokolle (relevante Teile) hinzugefügt haben:

Answer 1

behoben. Ich habe diese question gefolgt. Ich habe die tasks.py Broker IP-Adresse localhost (weil der RabbitMQ Port wie localhost Prozess zu hosten und verhalten ausgesetzt):

from celery import Celery 

app = Celery('tasks', backend='amqp', broker='amqp://guest@localhost') 

@app.task(name='tasks.add') 
def add(x, y): 
    return x + y 

Dann laufe ich die Behälter mit:

docker run -d --hostname my-rabbit --name some-rabbit -p 8080:15672 -p 5672:5672 rabbitmq:3-management 

docker run -v /Users/user/hostpath:/home/user --link some-rabbit:rabbit --name some-celery -d celery 

und hinzufügen celeryconfig.py Datei zu /Users/user/hostpath:

CELERY_IMPORTS = ('tasks') 
CELERY_IGNORE_RESULT = False 
CELERY_RESULT_BACKEND = 'amqp' 
CELERY_ACCEPT_CONTENT = ['pickle', 'json', 'msgpack', 'yaml'] 

und das ist Arbeit für mich :)
