EKS Setup and Configuration#

Amazon EKS runs the Kubernetes control plane for you – managed etcd, API server, and controller manager across multiple AZs. You are responsible for the worker nodes, networking configuration, and add-ons.

Cluster Creation Methods#

eksctl is the fastest path for a working cluster. It creates the VPC, subnets, NAT gateway, IAM roles, node groups, and kubeconfig in one command:

eksctl create cluster \
  --name my-cluster \
  --region us-east-1 \
  --version 1.31 \
  --nodegroup-name workers \
  --node-type m6i.large \
  --nodes 3 \
  --nodes-min 2 \
  --nodes-max 10 \
  --managed

For repeatable setups, use a ClusterConfig file:
