%nuclio build / deploy: Notebook HTTP 404 not found on JupyterHub

[yoshua0x]

Hello,

The build and deploy functions are throwing HTTP 404 errors on JupyterHub. The error is getting thrown by the notebook_file_name method when attempting to parse the notebook file URL from the iPython server.

Thanks to Yaron's assistance, a temporary work around was provided by using the filename as the parameter %nuclio build <filename>.ipynb <flags>.

def notebook_file_name(ikernel):
    """Return the full path of the jupyter notebook."""
    # Check that we're running under notebook
    if not (ikernel and ikernel.config['IPKernelApp']):
        return

    kernel_id = re.search('kernel-(.*).json',
                          ipykernel.connect.get_connection_file()).group(1)
    servers = list_running_servers()
    for srv in servers:
        query = {'token': srv.get('token', '')}
        url = urljoin(srv['url'], 'api/sessions') + '?' + urlencode(query)
        for session in json.load(urlopen(url)):

from notebook.notebookapp import list_running_servers
from urllib.parse import urljoin, urlencode
from urllib.request import urlopen
for srv in list_running_servers():
    query = {'token': srv.get('token', '')}
    url = urljoin(srv['url'], 'api/sessions') + '?' + urlencode(query)
    print(srv)
    print(url)
    print(urlopen(url).read())

returns:

{'base_url': '/user/dither/', 'hostname': '0.0.0.0', 'notebook_dir': '/home/jovyan', 'password': False, 'pid': 6, 'port': 8888, 'secure': False, 'token': '', 'url': 'http://0.0.0.0:8888/user/jdavis/'}

http://0.0.0.0:8888/user/dither/api/sessions?token=

HTTP 404 ERROR)

For reference: the suffix /user/.. is from running Jupyter via JupyterHub. We currently use the helm deployment on Kubernetes.

Package versions:
Nuclio version: 0.7.3
JupyterHub: 0.9.4
JupyterLab version: 1.0.4
Jupyter Notebook: 6.0.0

Working on this. Look at this issue but get 404 on http://127.0.0.1:60231/hub/api/oauth2/authorize..

Probably need to add some auth, will try to follow this blog post
