Create an EKS Cluster with Amazon Linux 2023

Using AL2023

Provisioning an EKS cluster using AMIs based on Amazon Linux 2023 (AL2023) follows the same pattern as creating a normal EKS cluster, but requires setting two variables in the IaC environment file (env.hcl):

locals {
  cluster_inputs = {
    ami_id           = "ami-0123456789abcdef0"  # replace with actual AMI ID
    default_ami_type = "AL2023_x86_64_STANDARD"
  }
}

This AWS guide describes how to obtain the correct Amazon Linux 2023 AMI ID for your region, which should result in running a command like the following:

aws ssm get-parameter --name /aws/service/eks/optimized-ami/1.30/amazon-linux-2023/x86_64/standard/recommended/image_id --region us-east-2 --query "Parameter.Value" --output text

Once you have obtained the correct AMI ID, set the ami_id and default_ami_type variables in your env.hcl as shown above, under the cluster_inputs section.
