This module is a Kube-Prometheus addon for https://github.com/aws-quickstart/cdk-eks-blueprints.

Kube-Prometheus on EKS

The Kube-Prometheus stack is meant for cluster monitoring, so it is pre-configured to collect metrics from all Kubernetes components. In addition to that it delivers a default set of dashboards and alerting rules. Many of the useful dashboards and alerts come from the kubernetes-mixin project, similar to this project it provides composable jsonnet as a library for users to customize to their needs.

Components included in this package:

• The Prometheus Operator
• Highly available Prometheus
• Highly available Alertmanager
• Prometheus node-exporter
• Prometheus Adapter for Kubernetes Metrics APIs
• kube-state-metrics
• Grafana

This example deploys the following resources

• Creates EKS Cluster Control plane with public endpoint (for demo purpose only) with a managed node group
• Deploys supporting add-ons: ClusterAutoScaler, AwsLoadBalancerController, VpcCni, CoreDns, KubeProxy, EbsCsiDriver
• Deploy Kube-Prometheurs on the EKS cluster

Note: we use EKS 1.21 here which is the latest EKS version supported by Kubeflow. see reference below
https://awslabs.github.io/kubeflow-manifests/docs/about/eks-compatibility/

Prerequisites:

Ensure that you have installed the following tools on your machine.

1. aws cli
2. kubectl
3. cdk
4. npm

Deploy EKS Cluster with Amazon EKS Blueprints for CDK

Clone the repository

git clone https://github.com/aws-samples/cdk-eks-blueprints-patterns.git

Create a CDK project, Bootstrap your environment and install dependency

cdk init app --language typescript
cdk bootstrap aws://<AWS_ACCOUNT_ID>/<AWS_REGION>
npm i @aws-quickstart/eks-blueprints
npm i kube-prometheus-eks-bluprints-addon

Replace the contents of bin/.ts with the following:

import 'source-map-support/register';
import * as cdk from 'aws-cdk-lib';
import * as blueprints from '@aws-quickstart/eks-blueprints';
import * as KubeflowAddOn from 'eks-blueprints-cdk-kubeflow-ext';
const app = new cdk.App();
// AddOns for the cluster.
const addOns: Array<blueprints.ClusterAddOn> = [
    new blueprints.addons.MetricsServerAddOn,
    new blueprints.addons.ClusterAutoScalerAddOn,
    new blueprints.addons.AwsLoadBalancerControllerAddOn(),
    new blueprints.addons.VpcCniAddOn(),
    new blueprints.addons.CoreDnsAddOn(),
    new blueprints.addons.KubeProxyAddOn(),
    new blueprints.addons.EbsCsiDriverAddOn(),
    new KubeflowAddOn({
         namespace: 'monitoring'
     })
];
const account = 'XXXXXXXXXXXXX'
const region = 'your region'
const props = { env: { account, region } }
new blueprints.EksBlueprint(app, { id: 'kube-prometheus-eks', addOns}, props)

Deploy the stack using the following command

cdk deploy

Verify the resources

Let’s verify the resources created by Steps above.

kubectl get nodes  # Output shows the EKS Managed Node group nodes

kubectl get ns | monitoring  # Output shows kubeflow namespace

kubectl get pods --namespace=monitoring  # Output shows kubeflow pods

Access Kube-Prometheus dashboards

log into Grafana UI by creating a port-forward to the grafana service

kubectl -n monitoring port-forward svc/blueprints-addon-prometheus-grafana 50080:80

and open this browser: http://localhost:50080/

Cleanup

To clean up your EKS Blueprints, run the following commands:

cdk destroy --all
