Configs to make a production-like network.
See the relevant folders for configuring DHCP, DNS, and deploying Kubernetes stuff for monitoring+storage+metallb+traefik.
If you want to run this in libvirt, make a new network and virsh net-edit foo, then remove the <dhcp> section under <ip>.
Provision your first system as the DNS+DHCP server. FreeBSD or some very lightweight distro is fine. DHCP+dns don't take much. Give it a static address, configure resolv.conf by hand, and once the services start, additional VMs will accept DHCP offers from it and work as "normal".
The range here does not match the range in dhcp or the metallb configuration. I don't know what you're going to pick, but make sure they line up.
