-There are many ways one can execute the above steps. Including automation through the use of HEAT to setup the OpenStack VMs.
-To better illustrate the steps involved, we have captured the manual creation of such an environment using the ONAP Wind River Open Lab.

Create Kubernetes Worker VMs
============================
The following instructions describe how to create OpenStack VMs to host the
-Highly-Available Kubernetes Workers. ONAP workloads will only be scheduled on these nodes.

Launch new VM instances
-----------------------
-The number and size of Worker VMs is depenedent on the size of the ONAP deployment.
-By default, all ONAP applications are deployed. It's possible to customize the deployment
-and enable a subset of the ONAP applications. For the purpose of this guide, however,
-we will deploy 12 Kubernetes Workers that have been sized to handle the entire ONAP
-application workload.

-script.

Download and install RKE on a VM, desktop or laptop.
Binaries can be found here for Linux and Mac: https://github.com/rancher/rke/releases/tag/v1.0.6
+ .. note::
+ There are several ways to install RKE. Further parts of this documentation assumes that you have rke command available.
+ If you don't know how to install RKE you may follow the below steps:
+
+ * chmod +x ./rke_linux-amd64
+ * sudo mv ./rke_linux-amd64 /user/local/bin/rke
+
RKE requires a *cluster.yml* as input. An example file is show below that
describes a Kubernetes cluster that will be mapped onto the OpenStack VMs
created earlier in this guide.

+You only need to install kubectl where you'll launch Kubernetes command. This

Usually, we use the first controller as it has also access to internal
Kubernetes services, which can be convenient.
