## Custom Nodes
Use Rancher to create a Kubernetes cluster on your on-premise bare metal servers. This option creates a cluster using a combination of [Docker Machine](https://docs.docker.com/machine/) and RKE, which is Rancher's own lightweight Kubernetes installer. In addition to bare metal servers, RKE can also create clusters on _any_ infrastructure provider by integrating with node drivers.
To use this option you'll need access to servers you intend to use as your Kubernetes cluster. Provision each server according to Rancher [requirements](#requirements), which includes some hardware specifications and Docker. After you install Docker on each server, run the command provided in the Rancher UI to turn each server into a Kubernetes node.
