Rancher RKE Kubernetes install notes

Rancher’s RKE is a Kubernetes cluster installer – see more here.


  • Docker must be running on the client machine where you are going to run the rke setup tool
  • The docs are not obvious, but the rke tool is run on a client machine to provision your cluster, it is not run on any of the target cluster nodes 

Notes using Ubuntu 16.04 server.

Remove prior Docker installs:

sudo apt-get remove docker docker-engine docker.io

Create docker group and add user to docker group:

sudo groupadd docker
usermod -aG docker <user_name>

Install per Docker CE install steps here, or use the Rancher provider install script here

Supported Docker versions for RKE (as of Dec 2018) are: 1.11.x 1.12.x 1.13.x 17.03.x

Configure Docker daemon to listen for incoming requests on 2376, as per steps here.

Using ‘rke config’ with the default/minimal cluster.yml here, and then install/setup with ‘rke up’

If you didn’t change the name of the cluster.yml file, after the install is complete, you’ll have a kube_config_cluster.yml file in the same dir which you can use with kubectl to interact with you cluster, or add it into your existing ~/.kube/config file
