Set up NGINX with sample traffic on Amazon EKS and Kubernetes

NGINX is a web server that can also be used as a load balancer and reverse proxy. For more information about how Kubernetes uses NGINX for ingress , see kubernetes/ingress-nginx.

To install Ingress-NGINX with a sample traffic service to test Container Insights Prometheus support
  1. Enter the following command to add the Helm ingress-nginx repo:

    helm repo add ingress-nginx
  2. Enter the following commands:

    kubectl create namespace nginx-ingress-sample helm install my-nginx ingress-nginx/ingress-nginx \ --namespace nginx-ingress-sample \ --set controller.metrics.enabled=true \ --set-string controller.metrics.service.annotations."prometheus\.io/port"="10254" \ --set-string controller.metrics.service.annotations."prometheus\.io/scrape"="true"
  3. Check whether the services started correctly by entering the following command:

    kubectl get service -n nginx-ingress-sample

    The output of this command should display several columns, including an EXTERNAL-IP column.

  4. Set an EXTERNAL-IP variable to the value of the EXTERNAL-IP column in the row of the NGINX ingress controller.

  5. Start some sample NGINX traffic by entering the following command.

    SAMPLE_TRAFFIC_NAMESPACE=nginx-sample-traffic curl | sed "s/{{external_ip}}/$EXTERNAL_IP/g" | sed "s/{{namespace}}/$SAMPLE_TRAFFIC_NAMESPACE/g" | kubectl apply -f -
  6. Enter the following command to confirm that all three pods are in the Running status.

    kubectl get pod -n $SAMPLE_TRAFFIC_NAMESPACE

    If they are running, you should soon see metrics in the ContainerInsights/Prometheus namespace.

To uninstall NGINX and the sample traffic application
  1. Delete the sample traffic service by entering the following command:

    kubectl delete namespace $SAMPLE_TRAFFIC_NAMESPACE
  2. Delete the NGINX egress by the Helm release name.

    helm uninstall my-nginx --namespace nginx-ingress-sample kubectl delete namespace nginx-ingress-sample
