1. Deploy the http-echo helm chart on AWS EKS


    Deploying an http-echo Helm chart on AWS EKS requires several steps. You need an EKS cluster, a Kubernetes context to deploy Helm charts, and the Helm chart itself. Below is a comprehensive guide and a Pulumi TypeScript program that sets up an EKS cluster and deploys the http-echo Helm chart to it.

    Before you begin, ensure you have Pulumi and AWS CLI installed and configured.

    1. Setting up the EKS Cluster: To create an EKS cluster, we use the eks.Cluster resource from the @pulumi/eks package. This package simplifies creating an EKS cluster by abstracting away a lot of the complexity.

    2. Deploying the Helm Chart: Once the cluster is available, you need to configure kubectl to communicate with the cluster. Pulumi does this automatically by creating a kubeconfig file.

      After this, you use the @pulumi/kubernetes/helm module to deploy the http-echo Helm chart. The helm.v3.Chart resource enables you to specify the chart, version, and any configuration that chart accepts.

    Below is the Pulumi TypeScript program:

    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("http-echo-cluster", { desiredCapacity: 2, // Desired number of worker nodes minSize: 1, // Minimum number of worker nodes maxSize: 3, // Maximum number of worker nodes instanceType: "t2.medium", // Size of the worker nodes providerCredentialOpts: { profileName: aws.config.profile, // Ensure your AWS profile is properly configured }, }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Create a provider to deploy Helm charts to the cluster. const provider = new k8s.Provider("http-echo-k8s", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the `http-echo` Helm chart to the cluster. const httpEchoChart = new k8s.helm.v3.Chart("http-echo", { chart: "http-echo", version: "0.2.3", // Specify the version of the Helm chart fetchOpts: { repo: "https://helm-repository/where/http-echo/is/stored", // Replace with the correct repository URL }, // Define values to override chart values. values: { replicaCount: 2, // Additional values can be added based on the chart's requirements. }, }, { provider }); // Export the URL of the load balancer assigned to the `http-echo` service. export const httpEchoUrl = httpEchoChart .getResourceProperty("v1/Service", "http-echo", "status") .apply(status => `http://${status.loadBalancer.ingress[0].hostname}`);

    Here's what the program is doing:

    • Initializes a new EKS cluster with a specific number of nodes and sizes for the worker nodes.
    • Exports the generated kubeconfig of the EKS cluster. It's the configuration file that kubectl and other Kubernetes tools use to interact with the cluster.
    • Creates a new Kubernetes provider instance configured to deploy resources in the EKS cluster.
    • Deploys the http-echo Helm chart using the familiar Helm CLI syntax and flow. Make sure to set chart to the name of the desired Helm chart and version to pin to a specific chart version.
    • Exports the URL of the http-echo service. This value can be used to access the http-echo service once it's deployed and an external load balancer is provisioned for it.

    By running this program with pulumi up, Pulumi will provision the resources in AWS, handle dependencies, and output the URL to access the http-echo service.

    Remember to replace https://helm-repository/where/http-echo/is/stored with the actual Helm repository where the http-echo chart is hosted. If you are not familiar with any Helm repository that hosts http-echo, you might need to find one or create your own Helm chart for it.

    After the deployment, you can access the http-echo service at the outputted URL, httpEchoUrl.

    Please ensure you have the necessary permissions and that your AWS CLI is configured correctly for Pulumi to create resources on your behalf.
