Easily install and configure a K3s agent using a K3os image and Proxmox Hypervisor.

First, we create a new Virtual Machine, in Proxmox, named k3os-agent-5.
Next, we install K3os, a purpose built operating system made to run kubernetes, on our virtual machine.
One tip I found for this is during installation, select to install as a server instead of an agent. Once installation is completed, the VM is restarted and we are able to SSH into the VM and re-configure the node as an agent and point to our existing k3s cluster.
Finally, I show the node up and running in Rancher.
