dev gateway config

[jhamman]

This adds dask-gateway to the dev deployment. Now that dask-gateway is part of the pangeo chart, all we need to do is to add the config below to the secrets section of each hub:

pangeo:
  jupyterhub:
    ...
    hub:
      services:
        dask-gateway:
          apiToken: SECRET1
  dask-gateway:
    gateway:
      proxyToken: "SECRET2"
      auth:
        type: jupyterhub
        jupyterhub:
          apiToken: "SECRET1"

I think you could also remove https://github.com/pangeo-data/pangeo-cloud-federation/blob/staging/dask-values.yaml

Do you also need to add a helm update for dask-gateway in https://github.com/pangeo-data/pangeo-cloud-federation/blob/staging/.circleci/config.yml#L228? Or do we get it indirectly via pangeo?

Nice!

Would be great to follow up with a comment here demonstrating how to use the new functionality #371.

I haven't been following closely, but it seems like dask-labextension probably doesn't work with gateway yet (dask/dask-gateway#55 (comment)).

Can we set configuration values here: https://github.com/pangeo-data/pangeo-stacks/blob/master/base-notebook/binder/dask_config.yaml ?

It works (kind of) with the master branch of dask-labextension, but not with the latest release. The fix was needed in dask-labextension not in dask-gateway.

Yes, dask-gateway supports configuration settings the same way as other dask projects. See https://gateway.dask.org/configuration-user.html for more information.

At a minimum, you'll probably want to fix configuration to set the addresses (gateway.address, gateway.proxy-address) as well as set gateway.auth.type to jupyterhub. This will allow users to create a gateway cluster with no parameters:

from dask_gateway import GatewayCluster

cluster = GatewayCluster()

For overall usage information, see https://gateway.dask.org/usage.html. Docs are still being written, so if you have questions that aren't answered here please let me know so we can improve them.

Merging to staging. We'll work on getting the gateway config setup once things are deployed there.
