Hello,
I’m trying to run JupyterHub in API-only mode. I got to the part where I start the user’s instance through API, however, when I try to navigate to the URL printed out by the Hub console, this is what happens:
This is the URL I get redirected to:
http://127.0.0.1:50585/hub/api/oauth2/authorize?client_id=jupyterhub-user-milos%2540milos.com&redirect_uri=%2Fuser%2Fmilos%40milos.com%2Foauth_callback&response_type=code&state=eyJ1dWlkIjogIjYyYTI2NzA0MmU2NTQzNmY5NmU0NmY5MjQxNTYzZmQwIiwgIm5leHRfdXJsIjogIi91c2VyL21pbG9zQG1pbG9zLmNvbS9sYWI_dG9rZW49In0
The environment I’m running the code in:
jupyter==1.0.0
jupyter_nbextensions_configurator==0.6.3
jupyterhub==4.0.2
notebook==6.5.4
configurable-http-proxy==0.3.0
jupyterlab==4.0.9
…with this JupyterHub config:
c = get_config() # noqa
c.JupyterHub.allow_named_servers = True
c.JupyterHub.spawner_class = "simple"
c.JupyterHub.authenticator_class = "dummy"
c.JupyterHub.hub_routespec = "/hub/api" # <-- API only mode
c.JupyterHub.services = [
{
"name": "my-service",
"url": "http://localhost:8012/services/my-service",
"admin": True,
"api_token": "812a587d-8c23-4a60-873e-713c87084076",
},
]
c.Authenticator.delete_invalid_users = True
And this is the console output when the local process spawner does it’s thing:

Read the migration plan to Notebook 7 to learn about the new features and the actions to take if you are using extensions.
https://jupyter-notebook.readthedocs.io/en/latest/migrate_to_notebook7.html
Please note that updating to Notebook 7 might break some of your extensions.

I was hoping that someone could maybe tell me what am I doing wrong. Haven’t had much luck with docs and examples.
Also, regarding this part: JupyterHub and OAuth — JupyterHub documentation
Does this mean that the Hub API must remain a public API because of oauth2 in, e.g., k8s setup?
