How to create an AWS EKS cluster using eksctl

eksctl dramatically simplifies the creation of AWS EKS clusters, by providing a simple command-line interface.

Step 1 – Define a Cluster YAML

You can either create a file called ekscluster.yaml and place the YAML in, or run the following command which will create a file called ekscluster.yaml and automatically add the default YAML configuration for you.

cat << EOF > ekscluster.yaml --- apiVersion: eksctl.io/v1alpha5 kind: ClusterConfig metadata: name: eksworkshop-eksctl region: ${AWS_REGION} version: "1.19" availabilityZones: ["${AZS[0]}", "${AZS[1]}", "${AZS[2]}"] managedNodeGroups: - name: nodegroup desiredCapacity: 3 instanceType: t3.small ssh: enableSsm: true # To enable all of the control plane logs, uncomment below: # cloudWatch: # clusterLogging: # enableTypes: ["*"] secretsEncryption: keyARN: ${MASTER_ARN} EOF
Code language: YAML (yaml)

Step 2 – Create the EKS Cluster

Tell the eksctl tool to create a new cluster using the ekscluster.yaml.

eksctl create cluster -f ekscluster.yaml
Code language: Bash (bash)
