This repo spins of a virtualbox VM with nested virtualization on, installs k8s and kata containers dependencies, deploys an example kata container, and runs some tests.
- Download and install Virtualbox and Vagrant.
- Clone repo.
- cd into the directory and run
vagrant up.
TLDR; K8s -> containerd -> kata -> qemu -> guest VM -> container
