Just to be clear: You can run Kubernetes on a single node. It just wont be "production ready", because the minimum qualifications of "production ready" has raised in Kube world. A single node running anything isn't production ready, let alone Kube. A single node running a nginx server isn't "production ready" anymore.

But Kubeadm will still do it. Kops if you're on AWS. GKE if you're on GCP. Just Docker would be easier to set up though, and that's what the OP means.
