Automated Standard EKS deployment

This repository contains Terraform scripts and Kubernetes resources to automate the deployment of a standard EKS cluster along with related resources and applications. It simplifies the provisioning and management of the EKS cluster, providing a quick way to get started with Kubernetes on AWS.

Overview

The deployment set up the following resources:

• VPC: A Virtual Private Cloud for isolating your cluster.
• EKS Cluster: Managed Kubernetes service that makes it easier to deploy, manage, and scale containerized applications.
• EKS Node Group: A group of worker nodes that register with the Kubernetes control plane.
• ArgoCD: Continuous Delivery tool for Kubernetes.
• AWS-LB Ingress Controller: Manages AWS Load Balancers for ingress traffic.
• External-DNS: Automatically manages external DNS records based on ingress and service resources.

Prerequisites

• AWS Account with necessary permissions
• Terraform v1.8+ installed
• kubectl v1.29+ installed
• AWS CLI configured with access credentials

Deploy Infrastructure

Update needed versions, AWS acctid and domain name in the tf files

cd terraform

terraform init
terraform plan -out plan.out
terraform apply plan.out

Note: You may have to apply twice

Sequence notes

• Make sure there is a valid public domain hosted in AWS R53
• Deploy vpc first (vpc, variables, versions)
• Add eks.tf and iam.tf into tf dir (being deployed from) then tfi, and then tfa
• Add argocd.tf into tf dir and then tfa

Deploy K8s resources

Update declarations in the following files with your account information:

• alb-controller.yaml

• cluster-autoscaler.yaml

• external-dns.yaml

• ingress-argo.yaml

cd ../k8s

cat *.yaml | kubectl apply -f -

Note: It may take around 5-10 minutes before all k8s deployments and resources are deployed.
