Kubernetes is a popular system for deploying distributed applications on clusters, particularly in the cloud. You can use Kubernetes to launch Dask workers in the following two ways:

  1. Helm: You can launch a Dask scheduler, several workers, and an optional Jupyter Notebook server on a Kubernetes easily using Helm.

    helm repo update          # get latest helm charts
    helm install stable/dask  # deploy standard dask chart

    This is a good choice if you want to do the following:

    1. Run a managed Dask cluster for a long period of time
    2. Also deploy a Jupyter server from which to run code,
    3. Share the same Dask cluster between many automated services
    4. Try out Dask for the first time on a cloud-based system like Amazon, Google, or Microsoft Azure (see also our Cloud documentation)

    See Dask and Helm documentation for more information.

  2. Native: You can quickly deploy Dask workers on Kubernetes from within a Python script or interactive session using Dask-Kubernetes.

    from dask_kubernetes import KubeCluster
    cluster = KubeCluster.from_yaml('worker-template.yaml')
    cluster.scale(20)  # add 20 workers
    cluster.adapt()    # or create and destroy workers dynamically based on workload
    from dask.distributed import Client
    client = Client(cluster)

    This is a good choice if you want to do the following:

    1. Dynamically create a personal and ephemeral deployment for interactive use
    2. Allow many individuals the ability to launch their own custom dask deployments, rather than depend on a centralized system
    3. Quickly adapt Dask cluster size to the current workload

    See Dask-Kubernetes documentation for more information.
