Set up AWS App Mesh sample workload on an Amazon EKS cluster with the EC2 launch type or a Kubernetes cluster - Amazon CloudWatch

Set up AWS App Mesh sample workload on an Amazon EKS cluster with the EC2 launch type or a Kubernetes cluster

Use these instructions if you are setting up App Mesh on a cluster running Amazon EKS with the EC2 launch type, or a Kubernetes cluster.

Configure IAM permissions

You must add the AWSAppMeshFullAccess policy to the IAM role for your Amazon EKS or Kubernetes node group. On Amazon EKS, this node group name looks similar to eksctl-integ-test-eks-prometheus-NodeInstanceRole-ABCDEFHIJKL. On Kubernetes, it might look similar to nodes.integ-test-kops-prometheus.k8s.local.

Install App Mesh

To install the App Mesh Kubernetes controller, follow the instructions in App Mesh Controller.

Install a sample application

aws-app-mesh-examples contains several Kubernetes App Mesh walkthroughs. For this tutorial, you install a sample color application that shows how http routes can use headers for matching incoming requests.

To use a sample App Mesh application to test Container Insights
  1. Install the application using these instructions: https://github.com/aws/aws-app-mesh-examples/tree/main/walkthroughs/howto-k8s-http-headers.

  2. Launch a curler pod to generate traffic:

    kubectl -n default run -it curler --image=tutum/curl /bin/bash
  3. Curl different endpoints by changing HTTP headers. Run the curl command multiple times, as shown:

    curl -H "color_header: blue" front.howto-k8s-http-headers.svc.cluster.local:8080/; echo; curl -H "color_header: red" front.howto-k8s-http-headers.svc.cluster.local:8080/; echo; curl -H "color_header: yellow" front.howto-k8s-http-headers.svc.cluster.local:8080/; echo;
  4. Open the CloudWatch console at https://console.aws.amazon.com/cloudwatch/.

  5. In the AWS Region where your cluster is running, choose Metrics in the navigation pane. The metric are in the ContainerInsights/Prometheus namespace.

  6. To see the CloudWatch Logs events, choose Log groups in the navigation pane. The events are in the log group /aws/containerinsights/your_cluster_name/prometheus in the log stream kubernetes-pod-appmesh-envoy.

Deleting the App Mesh test environment

When you have finished using App Mesh and the sample application, use the following commands to delete the unnecessary resources. Delete the sample application by entering the following command:

cd aws-app-mesh-examples/walkthroughs/howto-k8s-http-headers/ kubectl delete -f _output/manifest.yaml

Delete the App Mesh controller by entering the following command:

helm delete appmesh-controller -n appmesh-system
