Getting Started

Prerequisites

• AWS CLI configured with appropriate credentials
• kubectl
• Terraform >= 1.5

Deploy the base cluster

git clone https://github.com/aws-samples/sample-aws-eks-auto-mode.git
cd sample-aws-eks-auto-mode/terraform
terraform init
terraform apply -auto-approve

Configure kubectl:

$(terraform output -raw configure_kubectl)

Apply an example

Each example is self-contained. Pick one and apply:

kubectl apply -f examples/graviton/

Configuration

All inputs are defined in terraform/variables.tf. Override with -var flags or a terraform.tfvars file.

Variable	Description	Default
name	VPC and EKS cluster name	automode-cluster
region	AWS region	us-west-2
eks_cluster_version	Kubernetes version	1.34
vpc_cidr	VPC CIDR block	10.0.0.0/16
tags	Tags applied to all resources (5-layer)	{"auto-delete" = "never"}
base_domain	Route53 zone for HTTPS (empty = internal-only)	""
subdomain	Prefix under base_domain	""
ephemeral_storage_kms_key_id	KMS key for node storage encryption	""
enable_observability	CloudWatch Container Insights	false

Public exposure (opt-in)

By default, all workloads are internal-only. To expose on a real domain:

terraform apply \
  -var='base_domain=example.com' \
  -var='subdomain=automode' \
  -var='enable_observability=true'

Cleanup

./scripts/cleanup.sh
