1. Deploy the promexporter helm chart on AWS EKS


    To deploy the Prometheus exporter Helm chart on an Amazon EKS cluster using Pulumi, we will follow these steps:

    1. Set up an EKS cluster.
    2. Deploy the Prometheus exporter using the Helm chart on the EKS cluster.

    For the EKS cluster setup, we'll use the awsx and eks Pulumi libraries because they provide high-level abstractions to create and manage an EKS cluster. We'll then use the kubernetes Pulumi library, specifically the helm.sh/v3.Chart resource, to deploy the Helm chart on the EKS cluster.

    Here's a step-by-step Pulumi program in TypeScript to achieve this:

    import * as awsx from "@pulumi/awsx"; import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Create a VPC for our cluster. const vpc = new awsx.ec2.Vpc("my-vpc"); // Create an EKS cluster with the default configuration. const cluster = new eks.Cluster("my-cluster", { vpcId: vpc.id, subnetIds: vpc.publicSubnetIds, }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Create a Kubernetes provider that uses our EKS cluster. const provider = new k8s.Provider("provider", { kubeconfig: cluster.kubeconfig, }); // Deploy the Prometheus exporter Helm chart using the k8s provider. const promExporterChart = new k8s.helm.v3.Chart("promexporter", { chart: "prometheus-exporter", version: "1.0.0", // Specify the version of the Helm chart you wish to deploy. fetchOpts: { repo: "https://prometheus-community.github.io/helm-charts", }, }, { provider }); // Export the Prometheus service URL so we can easily access it. export const promService = promExporterChart.getResourceProperty("v1/Service", "promexporter-prometheus-exporter", "status");

    Explanation of the program:

    • VPC Creation: We first create a new AWS VPC with awsx.ec2.Vpc, which will contain our EKS cluster and associated resources.

    • EKS Cluster: The eks.Cluster resource creates an EKS cluster in the VPC that we just created. We are passing the VPC and subnet IDs to this resource, which signifies that the EKS cluster should be created within this VPC.

    • Kubeconfig Export: The kubeconfig is exported so that you can interact with your EKS cluster using kubectl on your local machine if necessary.

    • Kubernetes Provider: We initialize a Pulumi Kubernetes provider with the kubeconfig of the EKS cluster that we created. This provider is used to deploy Kubernetes manifests or Helm charts onto that cluster.

    • Prometheus Exporter Helm Chart: The k8s.helm.v3.Chart resource is used to deploy the Prometheus exporter Helm chart to the Kubernetes cluster. You specify the Helm chart name (prometheus-exporter), the version you require, and the Helm repository where the chart can be found.

    • Prometheus Service Export: After the Helm chart is deployed, we export the Prometheus service status for easy access. This could be expanded to include the exact URL by combining the service load balancer endpoint with the appropriate port.

    To apply this Pulumi program:

    1. Save the code in a file with a .ts extension (e.g., index.ts).
    2. Run pulumi up from the command line in the same directory as your file.

    This will provision the resources in your AWS account.

    Remember to replace the version and the repo values in the promExporterChart resource with the correct values for your use case. Also, note that the EKS cluster creation will incur costs in your AWS account, and managing those resources and costs is your responsibility.
