kubeadm not working

[kenroyandfamily]

Following the README it was simple to get up and running at http://localhost (on Mac OS 10.15.7)

But I can't get passed the first question :-)

I ran the following commands:

apt-get update

sudo is missing so I install it

apt-get install sudo

These commands come from https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/install-kubeadm/

sudo apt-get update && sudo apt-get install -y apt-transport-https curl curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add - cat <<EOF | sudo tee /etc/apt/sources.list.d/kubernetes.list deb https://apt.kubernetes.io/ kubernetes-xenial main EOF sudo apt-get update sudo apt-get install -y kubelet kubeadm kubectl sudo apt-mark hold kubelet kubeadm kubectl

But when I run "kubeadm init" I get the following error: W1107 15:30:50.563919 1034 kubelet.go:200] cannot automatically set CgroupDriver when starting the Kubelet: cannot execute 'docker info -f {{.CgroupDriver}}': executable file not found in $PATH

Basically the "docker" command is not found.

I've tried installing docker, but I get errors when trying to start it.
