I have several Docker hosts in my home lab as well as a k3s cluster and I'd really like to use k3s as much as possible. But when I want to figure out how to deploy basically any new package they say here are the Docker instructions, but if you want to use Kubernetes we have a Helm chart. So I invariably end up starting with the Docker instructions and writing my own Deployment/StatefulSet, Service, and Ingress yaml files by hand.
