hello,
I am trying to convert the dockerspawner setup into swarmspawner. All I am
getting is timeout.
The configuration I am using looking like this:
# Configuration file for JupyterHub.*
c.Application.log_level = 30
c.JupyterHub.ssl_key = '/etc/letsencrypt/live/jhub.z0z0.tk/privkey.pem'
c.JupyterHub.ssl_cert = '/etc/letsencrypt/live/jhub.z0z0.tk/fullchain.pem'
c.JupyterHub.port = 443
#from oauthenticator.github import LocalGitHubOAuthenticator
from oauthenticator.github import GitHubOAuthenticator
c.JupyterHub.authenticator_class = GitHubOAuthenticator
#c.LocalGitHubOAuthenticator.create_system_users = True
import os
c.JupyterHub.spawner_class = 'dockerspawner.SwarmSpawner'
c.SwarmSpawner.network_name = 'jupyterhub_network'
from jupyter_client.localinterfaces import public_ips
c.JupyterHub.hub_ip = '0.0.0.0'
c.JupyterHub.proxy_api_ip = '0.0.0.0'
#c.SwarmSpawner.extra_placement_spec = { 'constraints' : ['node.role==worker'] }
while I can see the service starting:
root@jupyterhub:~# docker service ls
ID NAME MODE REPLICAS
IMAGE PORTS
wtq7n8hvymwf jupyter-zozo6015 replicated 0/1
jupyterhub/singleuser:0.9
This is what I get in the logs:
