Download the AWS authenticator configuration map.

$ curl -O https://amazon-eks.s3-us-west-2.amazonaws.com/1.10.3/2018-06-05/aws-auth-cm.yaml

Edit the file and change the ARN for the NodeInstanceRole, you recorded in the previous step, https://www.lightnetics.com/post/10412

apiVersion: v1
kind: ConfigMap
metadata:
  name: aws-auth
  namespace: kube-system
data:
  mapRoles: |
    - rolearn: <ARN of instance role (not instance profile)>
      username: system:node:{{EC2PrivateDNSName}}
      groups:
        - system:bootstrappers
        - system:nodes

Apply the ConfigMap.

$ kubectl apply -f aws-auth-cm.yaml
configmap "aws-auth" created

Check the nodes have joined and are ready.

$ kubectl get nodes --watch
