Server not getting started - Docker container

JupyterHub

Hi all,

I used docker to install jupyterhub. I was able to access the jupyterhub ui , but I am unable to start the server.

Following is the error message I am getting

Follwing is the config I specified:
c = get_config() #noqa
c.Spawner.default_url = ‘/lab’
c.Authenticator.whitelist = {‘user1’, ‘user2’}
c.Authenticator.admin_users = {‘admin’}
c.JupyterHub.authenticator_class = ‘dummy’
c.DummyAuthenticator.password = “yourpassword”
c.JupyterHub.spawner_class = ‘jupyterhub.spawner.LocalProcessSpawner’
c.Spawner.user = ‘admin’

It looks like you’re trying to launch your singleuser servers inside the hub container, but since your users don’t exist LocalProcessSpawner will fail.

We’ve got an example Docker deployment in

which might be a good start for you?
