Setup multi-node cluster

In order to run a multi-node cluster with kind create the following kind-config.yaml file:

# three node (two workers) cluster config
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
- role: worker
- role: worker

Then start the cluster with the following command:

kind create cluster --config kind-config.yaml

Once run you should be able to see the cluster nodes up:

(⎈ |kind-kind:default)➜ kubectl get nodes
NAME                 STATUS   ROLES    AGE   VERSION
kind-control-plane   Ready    master   56m   v1.18.2
kind-worker          Ready    <none>   55m   v1.18.2
kind-worker2         Ready    <none>   55m   v1.18.2
