Type/provider of hosts: (VirtualBox/Bare-metal/AWS/GCE/DO) General cloud provider

Setup details: (single node rancher vs. HA rancher, internal DB vs. external DB) single node rancher

Environment Template: (Cattle/Kubernetes/Swarm/Mesos) Kubernetes with plane isolation required

Steps to Reproduce:

  1. Create a template from Kubernetes default but set: "Plane isolation = required"
  2. Create a rancher environment that use template just created
  3. Create a Virtual Machine and install docker with command provided by rancher documentation curl https://releases.rancher.com/install-docker/17.03.sh | sh
  4. Add this VM as rancher host with command provided by rancher UI adding label etcd=true and public IP
  5. Repeat these steps to add another 2 etcd hosts and 1 orchestration host (label orchestration=true)
  6. From Rancher UI, go to "Kubernetes -> CLI" and execute command kubectl describe nodes

Results:
===> Container Runtime Version: docker://Unknown

I tried also by installing same Docker version but instead to use script provided by rancher documentation I installed it manually but the output is the same.

This is a bug in Kubernetes, not being able to parse Docker CE structure, kubernetes/kubernetes#54039 and kubernetes/kubernetes#54040. This was released in v1.8.6 and v1.9, so will be included in newer releases of Rancher.
