1. Deploy the telegraf-ds-k3s helm chart on AWS EKS


    To deploy the telegraf-ds-k3s Helm chart on AWS EKS using Pulumi, we'll go through the following steps:

    1. Set up an EKS cluster using the @pulumi/eks package. This is a higher-level Pulumi package that simplifies the creation of EKS clusters.
    2. Once the cluster is created, we'll use the @pulumi/kubernetes package to deploy a Helm chart into our EKS cluster.

    Before we begin, ensure that you have installed the @pulumi/eks and @pulumi/kubernetes npm packages.

    Here's a detailed explanation of each of the resources and the program that you can use to deploy the telegraf-ds-k3s chart:

    1. EKS Cluster: This is a managed Kubernetes service provided by AWS that you can use to run Kubernetes workloads. In the program below, we create an EKS cluster by instantiating the Cluster class from the @pulumi/eks package.
    2. Helm Chart: Helm is a package manager for Kubernetes, which allows you to define, install, and upgrade even the most complex Kubernetes applications. Helm charts help you define, install, and upgrade even the most complex Kubernetes application. The telegraf-ds-k3s chart is a pre-packaged set of Kubernetes resources that you can deploy on an EKS cluster. In Pulumi, a Helm chart is represented by the Chart class from the @pulumi/kubernetes/helm/v3 module.
    import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster with the default configuration const cluster = new eks.Cluster("my-cluster", { // Requested version of Kubernetes. version: "1.21", // Other properties can be set here if needed, such as instance size or IAM role attachments. }); // Once the cluster is created, we can use the kubeconfig to configure k8s provider instances. const kubeconfig = cluster.kubeconfig.apply(JSON.stringify); // Create an instance of the Kubernetes provider with the EKS cluster's kubeconfig. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Deploy the telegraf-ds-k3s Helm chart into the cluster. const telegrafChart = new k8s.helm.v3.Chart( "telegraf", { chart: "telegraf-ds-k3s", // Here you specify the Helm repository, the chart name, and the version. version: "<chart-version>", // Specify your desired chart version here fetchOpts:{ repo: "https://helm.releases.telegraf.influxdata.com/", }, // If required, you can pass configuration values to the chart. values: { // Specify values used for configuring the chart. // e.g., image: { repository: "telegraf", tag: "1.15.3" } }, }, { provider: k8sProvider, // Specify the Kubernetes provider to use for deploying the chart. } ); // Export the cluster's kubeconfig and the hostname of the load balancer (if relevant). export const kubeconfigOutput = kubeconfig;

    In the program above:

    • We create an EKS cluster by using @pulumi/eks which abstracts away much of the boilerplate needed to set up an EKS cluster.
    • We create a new instance of @pulumi/kubernetes provider configured with the kubeconfig obtained from the EKS cluster. This allows you to manage Kubernetes resources in this cluster.
    • We deploy the telegraf-ds-k3s Helm chart to the cluster through the @pulumi/kubernetes/helm/v3 module by providing it with the name of the chart and the repository where the Helm chart is located.

    Please replace <chart-version> with the version of the telegraf-ds-k3s chart that you wish to install.

    To run this program, save it to a file index.ts, and run pulumi up from the command line. This will execute the Pulumi program, create the infrastructure, and deploy your Helm chart into the EKS cluster.
