Set up Amazon App Mesh sample workload on an Amazon EKS cluster with the Fargate launch type

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-fargate.

   Those instructions assume that you are creating a new cluster with the correct Fargate profile. If you want to use an Amazon EKS cluster that you've already set up, you can use the following commands to set up that cluster for this demonstration. Replace MyCluster with the name of your cluster.

   eksctl create iamserviceaccount --cluster MyCluster \
    --namespace howto-k8s-fargate \
    --name appmesh-pod \
    --attach-policy-arn arn:aws:iam::aws:policy/AWSAppMeshEnvoyAccess \
    --attach-policy-arn arn:aws:iam::aws:policy/AWSCloudMapDiscoverInstanceAccess \
    --attach-policy-arn arn:aws:iam::aws:policy/AWSXRayDaemonWriteAccess \
    --attach-policy-arn arn:aws:iam::aws:policy/CloudWatchLogsFullAccess \
    --attach-policy-arn arn:aws:iam::aws:policy/AWSAppMeshFullAccess \
    --attach-policy-arn arn:aws:iam::aws:policy/AWSCloudMapFullAccess \
    --override-existing-serviceaccounts \
    --approve

   eksctl create fargateprofile --cluster MyCluster \
   --namespace howto-k8s-fargate --name howto-k8s-fargate

2. Port forward the front application deployment:

   kubectl -n howto-k8s-fargate port-forward deployment/front 8080:8080

3. Curl the front app:

   while true; do  curl -s http://localhost:8080/color; sleep 0.1; echo ; done

4. Open the CloudWatch console at https://console.amazonaws.cn/cloudwatch/.

5. In the Amazon 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.
