Add new image for Dask hub #144

jacobtomlinson · 2021-02-22T11:54:56Z

In order for a Docker image to be used with the Daskhub helm chart it needs dask-gateway and jupyterhub-singleuser to be installed.

Neither of our official images have those packages so I propose we either add them to the notebook image or create a new image specifically for Daskhub.

The text was updated successfully, but these errors were encountered:

Sounds good! I have a slight preference for creating a new image, but you probably have a better sense of what makes sense here

chrisroat · 2021-09-17T04:59:13Z

More may be needed than simply adding those packages. I tried to roll my own images and it didn't work - I get 404s. If I use the latest dask-notebook, I see the same -- even when installing dask-gateway and jupyterhub-singleuser

Below is an example config that I installed on a local minikube, including those packages. (If you try to repro, don't use the latest k8s v1.22, which is starting to become the default download -- daskhub chart is not compatible). I also include below the logs from the hub and the user pod.

To note:

user pod gives 404 for /user/<username> url at the very end of the logs
hub logs claim Single-user server has no version header, which means it is likely < 0.8. Expected 1.4.2, though you can clearly see jupyterhub-singleuser 1.4.2 being installed on the user pod.
hub logs show 404 for all static files (e.g. css)

Adding @consideRatio , as this feels a bit like a jhub configuration update is needed, as well. I'd be interested to know what that might be, as I'm not sure how to get more information about what is going wrong.

Is jupyterhub-singleuser a conda package? I think jupyterhub-base is one. Are you sure you startup with the latest jupyterhub-singleuser script? The extra package thing must install the extra packages before running the jupyterhub-singleuser script that bundles as an entrypoint part of the python package jupyterhub, and jupyterhub-base contain that without dependecies like node only relevant if you run jh locally etc.

I think w. K8s 1.22, you need a new release of dask-gateway helm chart for several reasons, ive fixed them in current main branch but its not released yet.

There are also other things to fix, such disabling hub.networkPolicy.enabled=false, also fixed in latest main.

All help working towards a release of dask/dask-gateway appreciated.

jacobtomlinson · 2021-09-17T09:31:28Z

When I raised this issue I had successfully created a custom image (based on RAPIDS) which just added dask-gateway and jupyterhub-singleuser. Although I can't seem to find it now.

Is jupyterhub-singleuser a conda package?

Yeah

All help working towards a release of dask/dask-gateway appreciated.

This came up again at the Dask maintainers meeting this week. We are blocked with @jcrist being the only person who can do this. It looks like Jim should have some time for this soon though.

chrisroat · 2021-09-17T12:36:17Z

OK, so it sounds like there is still some work to do here. Deferring discussion of dask-gateway (for the moment -- let's come back to that), what needs to be done just to get jupyter working?

The base-notebook Dockerfile has:

# Configure container startup
ENTRYPOINT ["tini", "-g", "--"]
CMD ["start-notebook.sh"]

On the raw jupyter front, the dask entrypoint runs a prepare.sh script instead of tini, that installs packages and then does:

dask-docker/notebook/prepare.sh

Line 36 in 490c810

exec start.sh jupyter lab ${JUPYTERLAB_ARGS}

It seems tricky to do all 3:

install packages
keep the tini entrypoint
run start-singleuser.sh

Would switching prepare.sh to use exec start-singleuser.sh ${JUPYTERLAB_ARG} be acceptable (it continues to skip tini)?

Can we not change the entrypoint to prepare.sh start-singleuser.sh ${JUPYTERLAB_ARG}? The prepare script executes $@ anyway. We still lose tini here, but is that a big problem?

I think you are looking at the wrong prepare script. The one I referenced is in the notebook subdirectory. It's a bit convoluted -- maybe we should cleanup the prepare/entrypoint/cmd here.

I just verified that switching to exec start-singleuser.sh ${JUPYTERLAB_ARG} makes things work again -- no 404s.

It seems singleuser.defaultUrl isn't working to set the default to lab. Maybe it's related to
