Automate EKS cluster setup on AWS

You've joined a new and growing startup. The company wants to build its initial Kubernetes infrastructure on AWS.

They have asked you if you can help create the following:

• Terraform code that deploys an EKS cluster (whatever latest version is currently available) into an existing VPC
• The terraform code should also prepare anything needed for a pod to be able to assume an IAM role
• Include a short readme that explains how to use the Terraform repo and that also demonstrates how an end-user (a developer from the company) can run a pod on this new EKS cluster and also have an IAM role assigned that allows that pod to access an S3 bucket.

HowTo deploy

Prerequisites

• AWS account
  • access key / secret key for API access with proper permissions
  • aws-cli v2
• terraform >= v1.5
• kubectl >= v1.26

Steps:

• git clone this repo and deploy tf modules

terraform init
terraform apply

After everything was created - update k8s config and apply test-pod manifest (use your AWS account id instead placeholder, also replace it inside test_pod.yaml):

aws eks update-kubeconfig --region eu-west-1 --name test-eks-cluster
kubectl config use-context arn:aws:eks:eu-west-1:1111111111:cluster/test-eks-cluster
kubectl apply -f test_pod.yaml

After pod created you have to go inside and install awscli to check s3 access:

kubectl exec -it test-pod -- bash

Inside pod:

apt update
apt install -y awscli
aws s3 ls
