- Roles need to be explicitly granted, otherwise you get a
403. This example predates roles.
- Explicitly set bind_url - without this, JupyterHub itself doesn't
seem to bind anywhere, and so you just get a 404 when you visit
whatever port configurable-http-proxy lands on. This is probably
a separate bug to be investigated, but in the meantime copying
this from testing/jupyterhub_config.py makes this example actually
work
- Set DummyAuthenticator as the default, so users can get started
with this example
