I have 2 clusters, a bare metal cluster running on ARM SBCs (6x "Rock64" boards), and a 6x VM cluster run on Debian. I have a ton of spare hardware capacity, you could say. I'm not running much on it, just some postgres instances, ceph storage, grafana dashboards, and some custom apps. I installed it from scratch with kubeadm. I'm using calico for networking, and metallb for load balancing. The clusters are set up for HA, using haproxy.
