Help with xqueue

yaliu14 · February 26, 2020, 9:42am

docker ps shows the following:

tutor_local_cms_1
ad6638345c05        overhangio/openedx-xqueue:0.1.3             "/bin/sh -c 'gunicor…"   2 days ago          Up 2 days           8040/tcp                                   tutor_local_xqueue_1

what should the queuename be for this example:

I have an example grading script but i’m not sure how to connect to the xqueue. Any help would be much appreciated.

Hi @yaliu14! Any queue name should work just fine. Did you test it? Did it work? If not, what were the error logs?

yaliu14 · February 26, 2020, 11:28am

@regis, I did, at the lms interface I get:

Unable to deliver your submission to grader (Reason: Incorrect login credentials). Please try again later.

For the python3 script with the following code:

XQUEUE_URL = os.environ.get('XQUEUE_URL', '<lms URL>')
XQUEUE_LOGIN = '{}/xqueue/login/'.format(XQUEUE_URL)

def login():
    response = SESSION.post(XQUEUE_LOGIN, data={
        'username': XQUEUE_USER,
        'password': XQUEUE_PASSWORD,
    })
    return response.json().get('content', None) == 'Logged in'

I am unable to log in.

Anything else that might be useful?

I must admit I’m not very familiar with xqueue. What I can tell you is that the xqueue username is “lms”, the password can be obtained with tutor config printvalue XQUEUE_AUTH_PASSWORD and the url of the xqueue service should be http://xqueue:8040.

No problem, do you have a minimal example I can try out?
