Seconding k3d (and, by extension, k3s). If you’re in a market for sth suitable for more upstream-compliant clustering solution (k3s uses SQLite instead of etcd, iirc), RKE2 is also a great choice

If you’re careful - good teaware. Bought a couple of sets myself, as long as you don’t drop / break them - they’ll last!

And even if you do break it: get it to someone who knows kintsugi and enjoy it for the next crapton of years 😃
