Deploy EKS cluster using Terraform

• Terraform eks module: https://registry.terraform.io/modules/terraform-aws-modules/eks/aws/latest
  • 21 resources: aws_eks_cluster (Terraform EKS apply output, terraform show | grep resource)

Example

0) Download code

git clone https://github.com/hashicorp/learn-terraform-provision-eks-cluster

cd learn-terraform-provision-eks-cluster

1) Execute

terraform init #It may take several minutes
terraform apply
(Terraform EKS apply output)

1.1) Review execution

kubectl get nodes
The connection to the server localhost:8080 was refused - did you specify the right host or port?

2) Update configuration

Update kubeconfig with credentials:
aws eks --region $(terraform output -raw region) update-kubeconfig --name $(terraform output -raw cluster_name)
Added new context arn:aws:eks:us-east-2:XXXXXXX:cluster/myeks-eks-xxxx to /Users/youruser/.kube/config

3) Review resources:

 terraform show | grep -w resource | sort | uniq

4) Configure kubectl

aws eks list-clusters --output text | awk '{print $2}'
aws eks update-kubeconfig --name my-eks-cluster-name

5) Review cluster status/configuration

kubectl cluster-info
