Using rkt container engine

To use rkt as the container runtime run:

$ minikube start \
    --network-plugin=cni \
    --container-runtime=rkt

Using CRI-O

To use CRI-O as the container runtime, run:

$ minikube start \
    --network-plugin=cni \
    --container-runtime=cri-o \
    --bootstrapper=kubeadm

Or you can use the extended version:

$ minikube start \
    --network-plugin=cni \
    --extra-config=kubelet.container-runtime=remote \
    --extra-config=kubelet.container-runtime-endpoint=/var/run/crio/crio.sock \
    --extra-config=kubelet.image-service-endpoint=/var/run/crio/crio.sock \
    --bootstrapper=kubeadm
