While i can't really share the text (because it's all in Latvian), i did find that K3s is a pretty good option for when you want to use Kubernetes, but have pretty limited hardware resources. So much so, actually, that it used only slightly more resources than Docker Swarm (and, as a consequence, the deployments that were running on the nodes could serve almost equal amounts of requests under load).
Personally, i do believe that Kubernetes is sometimes overrated for simpler deployments, but if people don't mind the manifest syntax and are comfortable with the tool and its ecosystem, i think that K3s is probably the way to go in those situations (maybe with something like Portainer/dashboard running for graphical administration, if necessary). Such a good distribution, could probably even run it in prod with a HA setup.
