This can either be done using the AWS console service EFS or the AWS CLI and involves selecting a region and a VPC (subnets). For each node created, a specific AMI is used which also ensures docker and kubelet in addition to the AWS IAM authenticator is installed for security controls. You can create a cluster in minutes with just one command – eksctl create cluster!
