Applying the AWS ConfigMap to Enable Worker Nodes to Join the Cluster

You must apply the AWS ConfigMap so that the worker nodes can join your EKS cluster.

1. Connect to the bastion host.
2. Unpack the file arcsight-platform-cloud-installer-XX.X.X.XXX.zip located in the directory /aws-scripts/objectdefs.
3. From the unpacked file, open the file cm-aws-auth.yaml in any text editor.

4. Replace the placeholder ${WORKERS_ROLE_ARN} with the Role ARN value from your AWS worksheet, and then save your changes. The ConfigMap will then resemble the following example:

   apiVersion: v1
   kind: ConfigMap
   metadata:
   name: aws-auth
   namespace: kube-system
   data:
   mapRoles:
   - rolearn: arn:aws:iam::115370811111:role/srgdemo-workernodes-svc-role
   username: system:node:{{EC2PrivateDNSName}}
   groups:
   - system:bootstrappers
   - system:nodes

5. On the bastion, run the following command:

   kubectl apply -f cm-aws-auth.yaml

   This command will output:

   configmap/aws-auth created.
