1. Deploy the istio-authorizer helm chart on AWS EKS


    To deploy the istio-authorizer helm chart on AWS EKS, you'll need to perform several steps:

    1. Provision an Amazon EKS cluster.
    2. Configure Kubectl to connect to the new EKS cluster.
    3. Deploy the istio-authorizer Chart using the Helm package manager for Kubernetes.

    We'll create a Pulumi program in TypeScript that automates these steps. The program will use the following Pulumi resources:

    • eks.Cluster: This class provides a convenient way to create an AWS Elastic Kubernetes Service (EKS) cluster, its associated resources, and default node group. EKS Cluster documentation.
    • kubernetes.helm.v3.Chart: This class represents a Helm chart; Pulumi uses it to deploy containerized applications managed by Helm. Helm Chart documentation.

    Let's go through the Pulumi program that will create these resources:

    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 with the default configuration. const cluster = new eks.Cluster("my-cluster"); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Create a Kubernetes provider instance that uses our EKS cluster's kubeconfig. const provider = new k8s.Provider("provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the istio-authorizer helm chart. const istioAuthorizerChart = new k8s.helm.v3.Chart("istio-authorizer", { chart: "istio-authorizer", version: "1.0.0", // Use the correct version for the chart you wish to deploy. fetchOpts: { repo: "https://helm-repository-url/", // Replace with the correct Helm repository URL. }, }, { provider }); // Export the URL to access the Istio Authorizer (this might require more configuration depending on the chart). export const istioAuthorizerUrl = pulumi.interpolate`http://${provider.cluster.endpoint}/`;

    In the above program:

    • We import the necessary Pulumi libraries for managing resources on AWS and Kubernetes.
    • We create an EKS cluster with default settings, represented by eks.Cluster.
    • We export the kubeconfig of the cluster so that it can be used by external tools like kubectl.
    • We initialize a k8s.Provider to inform Pulumi how to communicate with the cluster.
    • We deploy the istio-authorizer helm chart by specifying its name and helm repository. You need to replace https://helm-repository-url/ with the actual URL of the istio-authorizer Helm chart's repository.
    • We export a URL that could potentially be used to access the Istio Authorizer, but note that this is just a placeholder and accessing the authorizer would typically involve additional steps like setting up ingress and DNS.

    Please make sure you replace the placeholder values with the actual values suited for your deployment. You might also need to add additional configuration parameters to customize the EKS cluster and istio-authorizer chart to your needs.

    To run this program, you'll need to have Pulumi installed and configured for use with your AWS account. Once programmed, you can deploy it using the Pulumi CLI with the following commands:

    # Login to Pulumi pulumi login # Create a new stack for your deployment (e.g., dev, staging, production) pulumi stack init dev # Install the necessary NPM modules npm install # Preview the deployment pulumi up --yes # After reviewing and approving the preview, the changes will be applied to AWS

    Remember that Helm charts may be configured with various settings which might require additional values or customizations, so it's important to review the chart's documentation to be aware of any configurable options.
