Current homelab+desktop+laptop host count here is 22. All anime characters or references. It’s a fairly large pool to pull from, so it’s worked for me for 20+ years now. Mobile devices (phones, tablets, etc) and game consoles aren’t really as clever though.
All of them are in a piHole DNS though so no host files keeps it easy to track. Services have names that mostly are just what they are though and cnames to the matching host that hosts them (or load balancer, whatever)
There’s a normal docker image, If this is all you want. However in all honesty, kubernetes is so nice to work with compared to running multiple docker compose things on the same host or the nightmare of a multi-host docker only lab. Just depends on how much homelab/selfhosting you’re doing. I know I’m grateful they included a helm chart here and I wish more self hosted software projects did as well. Options are always nice to have.
