I've seen plenty of single-node K8s setups that are actively used and maintained. If you're more after the IaC and K8s API and less concerned about raw HA, then it's a workable solution if you have enough RAM and CPU.
Some Kubernetes-based distributions, like OpenShift, require 3 masters at minimum, but that's not the norm across K8s installations.
