The "localkube" bootstrapper for Minikube has not been updated since k8s -1.10 (2018). Instead it is now using the official Kubernetes "kubeadm" bootstrapper, and up to 1.14
If you want an installation like this one with a smaller footprint, look at k3s 1.13+ (2019). It can be used both with Docker Machine (containerd) or with Podman Machine (cri-o)
This sets up a single-node Kubernetes installation, using the regular Boot2Docker ISO.
Tested with minikube version: v0.26.0 (latest) and kubernetes version: v1.10.0 (stable)

Use minikube-download to get the binaries, and minikube-install to install into a machine.
The entire minikube installation procedure looks something like this: machine-minikube.md
See https://github.com/kubernetes/minikube
It is possible to install using the default 1 vCPU / 1G RAM, but 2 vCPU / 2G RAM is recommended.
The default installation is around 1G, but more disk space might be needed for swap and overhead.
Total download is around 270M, plus the container images.

The minikube installation scripts need bash (not just /bin/sh), so make sure that it is installed.
