Implementation of EKS setup using Terraform. Terraform module located in terraform directory supports deployment to different AWS partitions. I have tested it with commercial and china partitions. I am actively using this configuration to run EKS setup in Ireland(eu-west-1), North Virginia(us-east-1) and Beijing(cn-north-1).

Module creates:

• VPC
• VPC Endpoints- S3, ECR, STS, APS, GuardDuty
• EKS Cluster
• EKS Node Group to run cluster critical services
• EKS Addons- coredns, kube-proxy, guardduty, aws-ebs-csi-driver, adot (requires cert-manger to be installed), kubecost
• IAM Roles for worker nodes and Karpenter nodes
• Additional IAM Roles for operators- load-balancer-controller, external-dns, cert-manager, adot-collector
• SQS queue configuraiton to be used with Karpeneter while utlising Spot Instances.

I am utilising Flux2 to deploy all additional configurations. You can find them at https://github.com/marcincuber/kubernetes-fluxv2 I have built this as a separate repository to show how to develop a successful configuration for your cluster using GitOps FluxV2 and Helm.

You will find configurations for:

• ALB ingress controller
• AWS Load Balancer controller
• AWS node termination handler
• Calico
• Cert Manager
• Cluster Autoscaler
• Dashboard
• External-DNS
• External Secrets Operator
• Metrics server
• Reloader
• VPC CNI Plugin
• EBS CSI Driver
• and more :)
