It probably does! Kamal/MRSK has been on the roadmap for awhile. I have deliberately endeavored to keep the existing k8s setup as minimal as possible, and it's still grown to almost unruly. That said, it works well enough across the (surprisingly power efficient) Dell C1100s in the basement, so it'd take a migration to justify, which is of course the last thing you can justify this with.
Which k8s distribution are you using? I’ve been using k3s on everything from individual home machines or cloud VMs, to small on-premise customer clusters for customers who don’t already have their own k8s clusters.
I don’t find it approaching unruliness, quite the opposite really.
If you're considering k8s, take a look at Kamal (also from DHH): https://kamal-deploy.org/
I think it makes more sense for small clusters.
