1. Deploy the elasticsearch-exporter helm chart on AWS EKS


    To deploy the elasticsearch-exporter Helm chart on an AWS Elastic Kubernetes Service (EKS) cluster, you will first need to set up an EKS cluster. Once the cluster is running, you can then install the Helm chart into your cluster.

    Below is a Pulumi program that first creates a new EKS cluster and then deploys the elasticsearch-exporter Helm chart onto it.

    I'll guide you through the process with detailed comments and explanations.

    Step 1: Setting up an EKS Cluster

    We will use the eks Pulumi package to create a managed Kubernetes cluster. The eks.Cluster class provides a high-level interface that simplifies EKS cluster creation.

    Step 2: Deploying the elasticsearch-exporter Helm Chart

    After we have our EKS cluster set up, we'll deploy the elasticsearch-exporter Helm chart using the kubernetes.helm.v3.Chart class from the kubernetes Pulumi package. The Chart resource allows us to deploy packaged applications to a Kubernetes cluster.

    Here is the TypeScript Pulumi program:

    import * as pulumi from '@pulumi/pulumi'; import * as aws from '@pulumi/aws'; import * as eks from '@pulumi/eks'; import * as k8s from '@pulumi/kubernetes'; // Step 1: Create a new EKS cluster const cluster = new eks.Cluster('my-cluster', { // We specify the desired number of cluster nodes here desiredCapacity: 2, minSize: 1, maxSize: 2, // This will use the default VPC and subnets vpcId: aws.config.vpcId, publicSubnetIds: aws.config.publicSubnetIds, // Define the instance type for the nodes instanceType: 't2.medium', // Define the Kubernetes version version: '1.21' }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Step 2: Deploy the `elasticsearch-exporter` Helm chart const elasticsearchExporterChart = new k8s.helm.v3.Chart('elasticsearch-exporter', { chart: 'elasticsearch-exporter', // You need to specify the repository where the chart is located repo: 'https://prometheus-community.github.io/helm-charts', namespace: 'monitoring', // Values allows you to provide a custom values file for your chart values: { // Define custom values needed for the elasticsearch-exporter Helm chart. // You would replace these with the actual configuration for your Elasticsearch setup. es: { uri: 'http://your-elasticsearch-cluster:9200' } }, // Ensure that the Helm chart is installed only after the EKS cluster is up and running transformations: [ (resource) => { if (resource.kind === 'Deployment') { resource.metadata.namespace = 'monitoring'; } }] }, { provider: cluster.provider }); // Since the program involves creating infrastructure, it would need to be executed with the Pulumi CLI. // You must have your AWS credentials and Pulumi CLI setup to run this program successfully.

    When you run this program with the Pulumi CLI, it performs the following actions:

    1. EKS Cluster Creation: An EKS cluster with the specified number of nodes, instance type, and Kubernetes version is created.
    2. Helm Chart Deployment: The elasticsearch-exporter Helm chart is then deployed onto the cluster into the monitoring namespace.
    3. Export Kubeconfig: The kubeconfig needed to connect and interact with your Kubernetes cluster is exported, which you can use with kubectl.

    Please ensure you've got Pulumi CLI set up with the required AWS credentials to allow Pulumi to create resources on your behalf and the Helm CLI installed so that Pulumi can fetch Helm charts.

    This program is meant to run "out of the box" within a properly configured Pulumi environment. If you encounter any errors during the process, you may need to review your cloud provider credentials, Helm chart repository availability, or chart values for elasticsearch-exporter.
