Creating a new Amazon EKS cluster with VPC¶

This example deploys the following:

New sample VPC, 3 Private Subnets and 3 Public Subnets
Internet gateway for Public Subnets and NAT Gateway for Private Subnets
EKS Cluster Control plane with one managed node group

Prerequisites¶

Note

Make sure to complete the prerequisites section before proceeding.

Setup¶

1. Download sources and initialize Terraform¶

git clone https://github.com/aws-observability/terraform-aws-observability-accelerator.git
cd examples/eks-cluster-with-vpc/
terraform init

2. AWS Region¶

Specify the AWS Region where the resources will be deployed:

export TF_VAR_aws_region=xxx

3. Cluster Name¶

Specify the name of your EKS cluster:

export TF_VAR_cluster_name=xxx

Deploy¶

Simply run this command to deploy the example

terraform apply

Additional configuration (optional)¶

1. Instance Type¶

Depending on your region or limitations in your account, you might need to change to a different instance type. To do this, you can define the instance type to use:

export TF_VAR_managed_node_instance_type=xxx

2. Amazon Elastic Kubernetes Service (Amazon EKS) Version¶

You can override the version of the cluster also:

export TF_VAR_eks_version=xxx

EKS Cluster details can be extracted from terraform output or from AWS Console to get the name of cluster. Use the following commands in your local machine where you want to interact with your EKS Cluster.

1. Run `update-kubeconfig` command¶

~/.kube/config file gets updated with cluster details and certificate from the below command

aws eks --region <enter-your-region> update-kubeconfig --name <cluster-name>

2. List all the worker nodes by running the command below¶

kubectl get nodes

3. List all the pods running in `kube-system` namespace¶

kubectl get pods -n kube-system

Cleanup¶

To clean up your environment, destroy the Terraform modules in reverse order.

Destroy the Kubernetes Add-ons, EKS cluster with Node groups and VPC

terraform destroy -target="module.eks_blueprints_kubernetes_addons" -auto-approve
terraform destroy -target="module.eks_blueprints" -auto-approve
terraform destroy -target="module.vpc" -auto-approve

Finally, destroy any additional resources that are not in the above modules

terraform destroy -auto-approve
