Note: EKS SSP for Terraform is in active development and should be considered a pre-production framework. Backwards incompatible Terraform changes are possible in future releases and support is best-effort by the EKS SSP community.

Welcome to the Amazon EKS Shared Services Platform (SSP) for Terraform.

This repository contains the source code for a Terraform framework that aims to accelerate the delivery of a batteries-included, multi-tenant container platform on top of Amazon EKS. This framework can be used by AWS customers, partners, and internal AWS teams to implement the foundational structure of a SSP according to AWS best practices and recommendations.

This project leverages the community terraform-aws-eks modules for deploying EKS Clusters.

The easiest way to get started with this framework is to follow our Getting Started guide.

For complete project documentation, please visit our documentation directory.

To view examples for how you can leverage this framework, see the examples directory.

The below demonstrates how you can leverage this framework to deploy an EKS cluster, a managed node group, and various Kubernetes add-ons.

module "eks-ssp" {
    source = "github.com/aws-samples/aws-eks-accelerator-for-terraform"

    # EKS CLUSTER
    kubernetes_version        = "1.21"
    vpc_id                    = "<vpcid>"                                      # Enter VPC ID
    private_subnet_ids        = ["<subnet-a>", "<subnet-b>", "<subnet-c>"]     # Enter Private Subnet IDs

  # EKS MANAGED NODE GROUPS
    managed_node_groups = {
      mg_m4l = {
        node_group_name = "managed-ondemand"
        instance_types  = ["m4.large"]
        subnet_ids      = ["<subnet-a>", "<subnet-b>", "<subnet-c>"]
      }
    }
}

#--------------------------------------------
# Deploy Kubernetes Add-ons with sub module
#--------------------------------------------
module "eks-ssp-kubernetes-addons" {
    source = "github.com/aws-samples/aws-eks-accelerator-for-terraform//modules/kubernetes-addons"

    eks_cluster_id                        = module.eks-ssp.eks_cluster_id

    # EKS Addons
    enable_amazon_eks_vpc_cni             = true
    enable_amazon_eks_coredns             = true
    enable_amazon_eks_kube_proxy          = true
    enable_amazon_eks_aws_ebs_csi_driver  = true

    #K8s Add-ons
    enable_aws_load_balancer_controller   = true
    enable_metrics_server                 = true
    enable_cluster_autoscaler             = true
    enable_aws_for_fluentbit              = true
    enable_argocd                         = true
    enable_ingress_nginx                  = true

    depends_on = [module.eks-ssp.managed_node_groups]
}

The code above will provision the following:

✅ A new EKS Cluster with a managed node group.
✅ Amazon EKS add-ons vpc-cni, CoreDNS, kube-proxy, and aws-ebs-csi-driver.
✅ Cluster Autoscaler and Metrics Server for scaling your workloads.
✅ Fluent Bit for routing logs.
✅ AWS Load Balancer Controller for distributing traffic.
✅ Argocd for declarative GitOps CD for Kubernetes.
✅ Nginx for managing ingress.

This framework provides out of the box support for a wide range of popular Kubernetes add-ons. By default, the Terraform Helm provider is used to deploy add-ons with publicly available Helm Charts. The framework provides support for leveraging self-hosted Helm Chart as well.

For complete documentation on deploying add-ons, please visit our add-on documentation

The root module calls into several submodules which provides support for deploying and integrating a number of external AWS services that can be used in concert with Amazon EKS. This included Amazon Managed Prometheus and EMR with EKS etc. For complete documentation on deploying external services, please visit our submodules documentation.

The Amazon EKS SSP for Terraform allows customers to easily configure and deploy a multi-tenant, enterprise-ready container platform on top of EKS. With a large number of design choices, deploying production-grade container platform can take a significant amount of time, involve integrating a wide range or AWS services and open source tools, and require deep understand of AWS and Kubernetes concepts. This solution handles integrating EKS with popular open source and partner tools, in addition to AWS services, in order to allow customers to deploy a cohesive container platform that can be offered as a service to application teams. It provides out-of-the-box support for common operational tasks such as auto-scaling workloads, collecting logs and metrics from both clusters and running applications, managing ingress and egress, configuring network policy, managing secrets, deploying workloads via GitOps, and more. Customers can leverage the solution to deploy a container platform and start onboarding workloads in days, rather than months.

For architectural details, step-by-step instructions, and customization options, see our official documentation site.
