1. Deploy the teleport-ent-auth helm chart on AWS EKS


    To deploy the teleport-ent-auth Helm chart on an AWS EKS cluster with Pulumi, follow these steps:

    1. Set up the EKS Cluster: We'll begin by provisioning an EKS cluster using the aws.eks.Cluster resource. This cluster will be the Kubernetes environment where your Helm chart will be deployed.

    2. Create IAM Roles: For the EKS cluster to function properly, you need an IAM role with the necessary AWS service permissions.

    3. Define Node Group: Define at least one node group with the aws.eks.NodeGroup resource, which specifies the worker nodes that the EKS cluster will use for deploying applications.

    4. Deploy Helm Chart: Using the kubernetes.helm.v3.Chart resource, we'll deploy the teleport-ent-auth helm chart onto the EKS cluster.

    Below is a step-by-step Pulumi program in TypeScript that sets up the EKS cluster and deploys the Helm chart:

    import * as eks from "@pulumi/eks"; import * as aws from "@pulumi/aws"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an EKS cluster const cluster = new eks.Cluster("my-cluster", { // Specify the version of Kubernetes you want to deploy version: "1.21", // Define the instance type and desired number of cluster nodes nodeGroup: { instanceType: "t2.medium", desiredCapacity: 2, minSize: 1, maxSize: 3, }, }); // Step 2: IAM Role for the EKS cluster - placeholder for actual role creation logic // Step 3: (Optional) If we need any specific NodeGroup configurations, we can add them here. // Now that we have our cluster, we can declare our Helm chart as follows: // Step 4: Deploy the teleport-ent-auth helm chart const helmChart = new k8s.helm.v3.Chart("teleport-ent-auth", { chart: "teleport-ent-auth", // Add your repository where the Helm chart is hosted if it's not in Helm's default repo fetchOpts: { repo: "https://charts.releases.teleport.dev/", }, // Specify the namespace and values.yaml parameters or custom values namespace: "default", values: { // Add any custom values that you want to override here }, }, { provider: cluster.provider }); // Export the Cluster Name and Kubeconfig export const clusterName = cluster.eksCluster.name; export const kubeconfig = cluster.kubeconfig;

    In this Pulumi program:

    • We first import the necessary packages: eks for AWS EKS resources, aws for AWS resources like IAM, and kubernetes for interacting with the Kubernetes cluster.
    • We use the eks.Cluster class from the @pulumi/eks package to provision an EKS cluster. To customize the cluster properties such as Kubernetes version or node group configurations, you can adjust the parameters in the Cluster constructor.
    • We mention a placeholder comment for IAM role creation, which can be done by defining an IAM role using the aws.iam.Role class and associating it with the EKS cluster with necessary policies attached.
    • We create a Helm chart resource using the k8s.helm.v3.Chart class, specifying the chart name and the repository where the Helm chart is located. Additionally, you can also supply any values you wish to override in the Helm chart's values.yaml.

    This example assumes you have Pulumi installed with AWS access configured. You can deploy this stack using the Pulumi CLI by placing this TypeScript code in an index.ts file, and then running pulumi up.
