Create an Amazon EKS Cluster

I've been using this Terraform module to deploy test EKS clusters for the longest time, but I just learned that it's even easier when using eksctl.

Create a cluster.yaml file with the following contents. You can change the instanceType and desiredCapacity (the number of nodes) if needed:

yaml
apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig
metadata:
 name: mheap-testing
 region: eu-west-2
nodeGroups:
 - name: ng-1
 instanceType: m5.large
 desiredCapacity: 1
 volumeSize: 80
 ssh:
 allow: false

Run eksctl create cluster. It takes around 4 minutes:

bash
eksctl create cluster -f cluster.yaml

Update your kubeconfig using the aws CLI:

bash
aws eks --region eu-west-2 update-kubeconfig --name mheap-testing

Now you can run all the kubectl commands that you want.

To delete the cluster when you're done:

bash
eksctl delete cluster -f cluster.yaml
