How to Authenticate Using Basic Auth in Dask-Gateway?

I added an environmental variable (the password) to a docker file, and then in the helm chart, I reference the environmental variable like so:

  auth:
    # The auth type to use. One of {simple, kerberos, jupyterhub, custom}.
    type: simple

    simple:
      # A shared password to use for all users.
      password: $DASK_GATEWAY_PASSWORD

Now when I try to establish a connection and invoke BasicAuth, it still says I’m unauthorized.

auth = BasicAuth(os.environ['DASK_GATEWAY_PASSWORD'])
gateway = Gateway(
    address=os.environ['IP_ADDRESS'],
    auth=auth
)

What happened: I cannot establish a connection w/ Dask Gateway when I enter BasicAuth information; I get the following error:

ClientResponseError: 401, message='Unauthorized'

Anything else we need to know?: I am using an internal load balancer on GCP to expose the proxy server. When I wasn’t using the simple authenticator, there were no issues establishing a connection to Dask Gateway

Environment:

• Dask-Gateway-Server version: latest
• Python version: 3.7.8

That narrows down the problem, which is good.

A few thoughts.

Looking at the client API documentation, it looks like the BasicAuth class expects username and password kwargs. Here’s the actual code. I would try the following from the client:

 auth = BasicAuth(username=None, password=<password>)

If that doesn’t work, you can try parsing the Gateway API logs via kubectl (kubectl log -f <Gateway API pod name>).

Thanks @droctothorpe, that seemed to do the trick. That was a bad oversight on my part!

might benefit from an example of how to configure the client, though I defer to Jim on that.

We could always use better docs, though I think that should go in the client docs, somewhere in https://gateway.dask.org/configuration-user.html#configuration
