Unable to add host to Rancher with Kubernetes env

Rancher 1.x
1

Hi Guys,

I am absolutely new to this Rancher - Kubernetes world, so please allow me to express the difficulties I’m facing.

Steps:

  1. I installed Rancher server and configured Kubernetes environment.
  2. Then I need to Add Host. I tried to add a VM with CentOS and Docker version 1.12.6-cs13.
    I installed this specific version of Docker only after going through the official guide of Rancher where it suggests to install Docker 1.12.3+ .
    http://rancher.com/docs/rancher/v1.5/en/hosts/#supported-docker-versions

But Ranhcer UI shows Unsupported Docker Version ?

What is an ideal environment to setup Rancher hosts ?

FYI: Rancher server is running in a separate VM.

Any help will be highly appreciated!
Thank You.
