Vagantfile for K3OS.
This Vagrantfile uses this libvirt box.
Vagrant cannot detect the operating system so you must run vagrant provision yourself.
This will replace the default K3S network plugin with Calico, and also copy your ~/.ssh/id_rsa.pub into the VM so that you can ssh directly.
vagrant up
vagrant provision
To obtain a kube-config file containing the VMs external IP:
vagrant ssh -- cat /etc/rancher/k3s/k3s-ext.yaml > k3s.yaml
