Configure Karpenter

Karpenter has been installed in our EKS cluster, and runs as a deployment:

~$kubectl get deployment -n karpenter

NAME        READY   UP-TO-DATE   AVAILABLE   AGE

karpenter   2/2     2            2           105s

The only setup that we will need to do is to update our EKS IAM mappings to allow Karpenter nodes to join the cluster:

~$eksctl create iamidentitymapping --cluster $EKS_CLUSTER_NAME \

--region=$AWS_REGION --arn $KARPENTER_NODE_ROLE \

--group system:bootstrappers --group system:nodes \

--username system:node:{{EC2PrivateDNSName}}
