Creating a k8s cluster on GKE is just as easy (a single gcloud command, or use the GUI if that is your preference).

With hosted Kubernetes as a service (GKE, AKS and soon EKS), there is little reason to roll your own cluster.

But you see with Docker Swarm, you don't need "Docker Swarm as a service". That's why Docker Swarm wins in simplicity.
