 The Dask Operator is a set of custom resources and a controller that runs on your Kubernetes cluster and allows you to create and manage your Dask clusters as Kubernetes resources.

----------------------------------------
+----------------------------------------
 
 The operator manages a hierarchy of resources, some custom resources to represent Dask primitives like clusters and worker groups, and native Kubernetes resources such as pods and services to run the cluster processes and facilitate communication.
