1. Deploy the elastic-metricbeat helm chart on AWS EKS

    TypeScript

    To deploy the elastic-metricbeat Helm chart on an AWS EKS cluster using Pulumi, we need to perform several tasks:

    1. Create an EKS cluster if one does not already exist.
    2. Install the Helm chart on the EKS cluster.

    For these tasks, we will use the @pulumi/eks package to create and configure an EKS cluster and the @pulumi/kubernetes package to handle Helm chart deployment.

    Let's break down the steps:

    1. EKS Cluster Creation: We will create an EKS cluster using the Cluster class from the @pulumi/eks package. This will set up the control plane, default node group, and other necessary configurations.

    2. Helm Chart Deployment: Once the EKS cluster is ready, we will deploy the elastic-metricbeat Helm chart using the Chart class from the @pulumi/kubernetes package. This class allows us to specify the chart name, version, and any values to override.

    First, let's install the necessary Pulumi packages for our TypeScript program:

    npm install @pulumi/pulumi @pulumi/aws @pulumi/eks @pulumi/kubernetes

    Now, let's write the TypeScript program:

    import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // This creates a new EKS cluster with the default configuration. // Refer to the EKS documentation for customizing your cluster: // https://www.pulumi.com/registry/packages/eks/api-docs/cluster/ const cluster = new eks.Cluster("my-cluster"); // Once the cluster is created, we configure the K8s provider to use the kubeconfig from the cluster. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig, }); // Deploy elastic-metricbeat Helm chart using the k8s provider. // Refer to the Helm chart resource documentation for more information and configuration options: // https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm.sh/v3/chart/ const metricbeat = new k8s.helm.v3.Chart( "elastic-metricbeat", { chart: "metricbeat", version: "7.12.0", // Specify the version of the chart you wish to deploy. fetchOpts: { repo: "https://helm.elastic.co", // The Helm repository where the chart is hosted. }, // Customize metricbeat settings by providing the necessary values here. // values: { ... } }, { provider: k8sProvider } ); // Export the cluster's kubeconfig and the Helm release's status as stack outputs. export const kubeconfig = cluster.kubeconfig; export const metricbeatStatus = metricbeat.status;

    Here's a detailed explanation of the program:

    • We begin by importing the required Pulumi packages for managing EKS and Kubernetes resources.
    • We create a new EKS cluster using the eks.Cluster class. This cluster will have the control plane, worker nodes, and other resources needed to run Kubernetes applications.
    • A k8s.Provider is then instantiated using the kubeconfig generated by the EKS cluster, which enables the Pulumi Kubernetes provider to communicate with the new EKS cluster.
    • With the Kubernetes provider now configured, we create a Helm chart resource for elastic-metricbeat. We specify the chart name, chart version, and repository where the chart resides.
    • Optionally, you can override the default values of the metricbeat Helm chart by providing a values object.
    • Finally, we export the kubeconfig needed to interact with the cluster and the release status of the metricbeat Helm chart as stack outputs.

    Running the program would set up your EKS cluster and deploy the elastic-metricbeat Helm chart on it, enabling you to monitor Kubernetes cluster metrics.
