Kubernetes¶

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:

Helm: You can launch a Dask scheduler, several workers, and an optional Jupyter Notebook server on a Kubernetes easily using Helm
```
helm repo add dask https://helm.dask.org/    # add the Dask Helm chart repository
helm repo update                             # get latest Helm charts
helm install dask/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)
Note

For more information, see Dask and Helm documentation.
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
Note

For more information, see Dask-Kubernetes documentation.
