Topology aware hints demo

This code is used to demostrate usage of TopologyAwareHints introduced on Kubernetes 1.27.

What's included

• An Amazon EKS cluster
• AWS Distro for OpenTelemetry (ADOT) Operator
• Sample Application

Prerequisites

• Basic understanding of Linux operating systems and Kubernetes.
• An AWS account.
• Administrator or equivalent access to deploy the required resources.
• AWS Command Line Interface (AWS CLI) (v2.6.3+) installed and configured.
• Terraform CLI installed
• git CLI installed
• kubectl, and helm client installed

Deploy

Run the following command to deploy the cluster. Replace ap-southeast-1 to your Region. This process may take 20–30 minutes.

export AWS_REGION="ap-southeast-1"
terraform init
terraform plan
terraform apply -auto-approve

Once the Terraform has completed, then you can set up kubectl by running this command:

aws eks --region $AWS_REGION update-kubeconfig --name tar-demo-cluster

Run the following command to deploy the sample application:

cd ../kubernetes
kubectl apply --server-side -f common.yaml
kubectl apply --server-side -f simple.yaml

Get the endpoint for user interface (UI) component by running the following command:

kubectl get svc ui-lb -n ui -o jsonpath={.status.loadBalancer.ingress[0].hostname}

You can access the demo application by accessing http://<link>/home. This displays an example online shopping site.
