    In this attempt, we will:

Use Docker-Machine-Driver-Linode to provision a Linode with Docker-CE
Run Rancher 2.x in that Docker-CE
Install the Docker-Machine-Driver-Linode binary in Rancher
Create a Template with the Necessary Settings
Create a Rancher Kubernetes Cluster
a. First Try Ubuntu (failure)
b. Then Try CoreOS
Next Steps

Use Docker-Machine-Driver-Linode to provision a Linode with Docker-CE

Install the docker-machine-driver-linode binary from https://github.com/linode/docker-machine-driver-linode/releases
Be sure to grab the appropriate binary for your operating system.
$ docker-machine create -d linode --linode-token $LINODE_TOKEN --linode-root-pass $(openssl rand -base64 32) dockode

Docker is up and running!
To see how to connect your Docker Client to the Docker Engine running on this virtual machine, run: docker-machine env dockode

Now configure this as the backend for the Docker commands to follow.
$ eval $(docker-machine env dockode)

Run Rancher on the Linode (using the local Docker client)

Launch Rancher.
docker run -d -p 80:80 -p 443:443 rancher/rancher

Access port 443 on the Linode running docker and accept the certificate.
open https://$(docker-machine ip dockode):443/

Install the Docker-Machine-Driver-Linode binary in Rancher

Use the Latest Linode Docker Machine for Linux binary from the Github Releases:
https://github.com/linode/docker-machine-driver-linode/releases/download/v0.1.0/docker-machine-driver-linode_linux-amd64.zip

Use the Latest release of the Linode UI for Rancher:
https://github.com/displague/ui-driver-linode/releases/download/v0.1.0/component.js

Omitting this step will reveal all Docker Machine Driver options. Here be dragons.  You'll want to provide the Region, Image, and Instance Type using the APIv4 IDs.  You'll also need to provide a Root Pass, SSH User (core for containerlinux, root for everything else).

Create a Template with the Necessary Settings


Create a Rancher Kubernetes Cluster

First Try Ubuntu (failure)


Then Try CoreOS


This cluster is currently Provisioning; areas that interact directly with it will not be available until the API is ready.
[pre-deploy] Pulling image [rancher/hyperkube:v1.11.3-rancher1] on host [192.155.90.133]

This cluster is currently Provisioning; areas that interact directly with it will not be available until the API is ready.
[addons] Saving addon ConfigMap to Kubernetes

Failed to get Kubernetes server version: Get https://173.255.238.177:6443/version: can not build dialer to c-qm8ln:m-2pbwc

Reduce the cluster count to 1 node.  It works!


But after a few minutes, ContainerLinux will reboot.  And the Kubernetes services will not restart.
This cluster is currently Unavailable; areas that interact directly with it will not be available until the API is ready.
Failed to communicate with API server: Get https://45.33.66.78:6443/api/v1/componentstatuses?timeout=30s: waiting for cluster agent to connect

Next Steps

Fix https://github.com/displague/ui-driver-linode so that the Rancher UI can present drop downs with human values instead of raw Linode API values (Region, Kernel, Instance Type, Image dropdowns)
