So here’s the thing. This year I fell in love wih clojure, it’s an absolute pleasure to program in. It’s also a hosted language that runs on java (primarily) or javascript (or a bunch of marginalized things). And honestly, I feel like I can make the java backend run more resource-effecient than the JS one.
I run k3s in my homelab as a single node cluster. I’m very familiar with kubernetes in general, so it’s just easier for me to reason with a control plane.
Some of the benefits I find useful:
k3s is, of course, a memory hog, I’d estimate it and cilium (my CNS of choice) eat up about 2Gb ram and a bit under one core. It’s something you can tune to some extent, though. But then, I can easily do pod routing via VPN and create services that will automatically get a public IP from my endless IPv6 pool and get that address assigned a DNS name in like 10 lines of Yaml.
