The JupyterHub AMI includes Dask and it's JupyterLab extension.
You can use this extension to create a Dask cluster or to connect to a running one.
Connecting to a running Dask cluster¶
If you create a Dask cluster using Python, for example:
from dask.distributed import Client client = Client()
You can connect the extension to this cluster using the Dashboard URL:
Paste this URL at the top of the Dask extension.
After that click on any of the metrics to create new Panes in Jupyter Lab.
