Interesting read. I have just setup a very similar cluster this week: 3 node bare metal cluster in a 10G mesh network. Decided for Debian, RKE2, Calico and Longhorn. Encryption is done using LUKS FDE. For Load Balancing I am using the HCloud Load Balancer (in TCP mode). At first I had some problems with the mesh network as the CNI would only bind to a single interface. Finally solved it using a bridge, veth and isolated ports.
