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


    To deploy the mysql-exporter Helm chart on AWS EKS using Pulumi, we need to:

    1. Set up an Amazon EKS cluster.
    2. Install the Helm chart onto the EKS cluster.

    Step 1: Setting up the EKS Cluster

    We will use the eks.Cluster class from the @pulumi/eks package to create a new Amazon EKS cluster. This package provides higher-level abstractions to create and configure an EKS cluster.

    Step 2: Deploying the mysql-exporter Helm Chart

    After the cluster is set up, we will use the kubernetes.helm.v3.Chart class from the @pulumi/kubernetes package to deploy the mysql-exporter Helm chart to the EKS cluster.

    Let's get started with the Pulumi program in TypeScript:

    import * as pulumi from "@pulumi/pulumi"; import * as aws from "@pulumi/aws"; import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster const cluster = new eks.Cluster("my-cluster", {}); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeconfig; // Deploy the mysql-exporter Helm chart const chart = new k8s.helm.v3.Chart("mysql-exporter", { // Note that depending on the specific chart, you may need to provide the appropriate // repository and chart name. For illustrative purposes, I am assuming "mysql-exporter" // chart is available in the stable Helm repository. chart: "mysql-exporter", version: "1.0.0", // specify the version of the chart to deploy namespace: "monitoring", // specify the namespace where the chart will be installed fetchOpts: { // Define the repository where the chart is located repo: "https://charts.helm.sh/stable", }, // Values from the default chart values can be overridden using a values object values: { // Custom values to configure mysql-exporter }, }, { provider: cluster.provider }); // Export the Helm chart status export const chartStatus = chart.status;

    In this program:

    • We create a new EKS cluster using the eks.Cluster class. The minimal construction creates an EKS cluster with the default configurations, including default node groups and networking setup.
    • The kubeconfig is exported, allowing you to interact with your cluster using kubectl or other Kubernetes tools.
    • We create a new Helm chart deployment using the Chart class. The mysql-exporter Helm chart is specified along with version and namespace. The fetchOpts is where we specify the Helm repository; in this case, I've provided a placeholder URL where your Helm chart might reside.
    • In the values object within the Chart class, you can override any default values provided by the Helm chart with custom configurations. For example, you might need to specify the MySQL service credentials or connection info for the mysql-exporter to function correctly.
    • We also export the status of the Helm chart, which provides information about the deployed resources, using chart.status.

    This Pulumi program sets up an EKS cluster and deploys the mysql-exporter Helm chart onto it. Remember to replace the chart-specific values and repository URL with the correct ones for your use case.

    After writing this code, to deploy your infrastructure, run pulumi up in the directory where this code is saved.
