How is the Kubernetes cluster driver specified in minikube?

The Kubernetes cluster driver in Minikube can be specified using the --driver flag when starting Minikube. For example, to specify the Docker driver, you would use the following command:

minikube start --driver=docker

If you do not specify a driver, Minikube will automatically select a default driver based on your system configuration. You can also check the available drivers by running:

minikube drivers

This will list all the drivers that are supported on your machine.
