You have to bring all of those same things to a Nomad deployment as well. It’s generally more lightweight than Kubernetes, so it might be easier to wire those other components in, but you do still need to do that work either way.
IMO the few lines of yaml to set the path/host for an Ingress definition seems cleaner to me than using consul-template to spit out some LB config (as in the post's example).
For simplicity, a few years ago I preferred Traefik + Swarm. Add a label or two and you're done. But Swarm died :/
