1. Deploy the ipa helm chart on AWS EKS

    TypeScript

    To deploy the IPA Helm chart on AWS EKS, we'll take a step-by-step approach to set up an EKS (Elastic Kubernetes Service) cluster, configure it, and then deploy the IPA Helm chart on it using Pulumi with TypeScript.

    We will perform the following steps:

    1. Create an EKS cluster using the eks.Cluster component, which abstracts away a lot of the complexity of setting up an EKS cluster.
    2. Use the kubernetes.helm.v3.Chart resource to deploy the IPA Helm chart onto the EKS cluster.

    Below is the Pulumi TypeScript program that accomplishes these steps. Make sure you have the Pulumi CLI installed, and your AWS credentials configured. The chart name "ipa" is assumed to be available in the Helm repository; if it's not, replace it with the correct chart name and repository.

    Let's begin by installing the necessary Pulumi packages for AWS EKS and Kubernetes:

    $ npm install @pulumi/eks @pulumi/kubernetes

    Here's the TypeScript program:

    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", { instanceType: "t2.medium", // Choose an appropriate instance type. desiredCapacity: 2, // Set the desired number of worker nodes. minSize: 1, // Set the minimum number of worker nodes. maxSize: 3, // Set the maximum number of worker nodes. }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Create a Helm chart resource that deploys the IPA application. const ipaChart = new k8s.helm.v3.Chart("ipa", { chart: "ipa", // Replace with the correct repository or local path if needed fetchOpts: { repo: "http://myhelmrepo.org/charts", }, // Specify the version if needed version: "1.2.3", namespace: "default", // The target namespace for the Helm chart. values: { // Specify the custom values for the Helm chart. // These values will override the default values of the chart. }, }, { provider: cluster.provider }); // Optional: Export the Helm chart deployment name. export const ipaDeploymentName = ipaChart.getResourceProperty("v1/Service", "ipa", "metadata").apply(m => m.name);

    Explanation:

    • We import @pulumi/eks which provides a high-level interface to deploy EKS clusters.
    • We create an EKS cluster with the desired configuration using new eks.Cluster. To customize the cluster, you can provide additional input properties such as vpcId and subnetIds if you want to run the cluster in an existing VPC (EKS Cluster Resource Properties).
    • The kubeconfig is exported, which will give you access to your EKS cluster using kubectl.
    • We import @pulumi/kubernetes for managing Kubernetes resources, including Helm charts.
    • We deploy the IPA Helm chart by creating a new k8s.helm.v3.Chart, where you provide the chart name, chart version, and the values that map to the configuration options of the Helm chart (Helm Chart Resource Properties).
    • Be sure to specify the correct Helm repository where the IPA chart is hosted and the chart's version.
    • The provider option is passed to the Helm chart indicating that this Helm chart is deployed on the created EKS cluster.
    • Lastly, we optionally export the name of the Kubernetes Service created by the Helm chart, which can be useful if you want to verify the deployment or access the deployed service.

    To deploy this program, execute it with Pulumi by running the following commands:

    $ pulumi stack init dev # Set up a Pulumi stack $ pulumi up # Deploy the EKS cluster and the Helm chart

    Pulumi will perform the deployment, and you can follow the progress in the terminal or on the Pulumi Console via the URL that Pulumi will provide.

    Remember to destroy the resources with pulumi destroy when you're done to avoid incurring unwanted costs.
