Update Dask Tutorial. #87

Open julienchastang opened 1 day ago

julienchastang commented 1 day ago

Hi Andrea,

I am currently troubleshooting an issue with the Dask Gateway API. While accessing the API through Traefik works (e.g., http://traefik-dask-gateway/services/dask-gateway/api/health returns a 200 OK response), access via the service IP returns 404 Not Found errors for all tested endpoints.

I don't know if I am doing something wrong or the tutorial may need an update.

Thanks.

@julienchastang sure, how urgent is it? Do you have a tutorial/class starting soon?

julienchastang commented 1 day ago

Thanks for the quick response. My colleague at U Wisc is doing a class using Dask on December 6. However, I'd like to have some margin of error given the difficulties I've had with Dask in the past an also the forthcoming holidays. Again, thank you very much for this.

I keep seeing errors like those below. The cluster appears to try to start, but then seems to immediately die. Those logs are from the api-dask-gateway- pod.
