 Docker Desktop includes a standalone Kubernetes server and client, as well as Docker CLI integration, enabling local Kubernetes development and testing directly on your machine.

 ## What happens when I enable Kubernetes in Docker Desktop?
 
 When you enable Kubernetes in Docker Desktop, the following actions are triggered in the Docker Desktop backend and VM:
