1. Deploy the istio-aws-private-ingress-customized helm chart on Azure Kubernetes Service (AKS)

    TypeScript

    Deploying an Istio Helm chart specifically configured for AWS on Azure Kubernetes Service (AKS) would not be appropriate as Istio configurations for AWS could be incompatible with Azure's infrastructure. Instead, we can deploy a generic Istio Helm chart on AKS, tailoring some of the configurations to suit the Azure environment where necessary.

    Below is a step-by-step Pulumi program that deploys an Istio Helm chart on an AKS cluster. To complete this task, you need to have an existing AKS cluster. For simplicity, this example will outline the steps to deploy a Helm chart to the cluster.

    In the program, we will make use of the following resources:

    • kubernetes.helm.sh/v3.Chart from the kubernetes provider: This resource is used to deploy Helm charts to a Kubernetes cluster. For Istio, it will pick up the chart from the specified Helm repository.

    Here's a Pulumi program written in TypeScript, which you can use as a starting point to deploy the Istio Helm chart on an AKS cluster:

    import * as k8s from "@pulumi/kubernetes"; const clusterName = "<your-aks-cluster-name>"; // replace with the name of your AKS cluster const resourceGroupName = "<your-resource-group-name>"; // replace with the name of your resource group // Create a provider for the existing AKS cluster. const aksCluster = new k8s.Provider("aksProvider", { kubeconfig: ... // Provide your AKS cluster kubeconfig }); // Deploy the Istio Helm chart. const istio = new k8s.helm.sh.v3.Chart("istio", { chart: "istio", version: "...", // specify the version of Istio you want to deploy namespace: "istio-system", fetchOpts: { repo: "https://istio-release.storage.googleapis.com/charts", }, }, { provider: aksCluster }); // Export the name of the Istio chart. export const istioChartName = istio.metadata.apply(m => m.name);

    Before running this Pulumi program, you will need to replace the placeholder values with actual values relevant to your Azure environment. Specifically:

    • <your-aks-cluster-name>: The name of your AKS cluster.
    • <your-resource-group-name>: The name of the resource group that contains your AKS cluster.

    Also, you need to provide the kubeconfig for the AKS cluster. Usually, this would be obtained through the Azure CLI or the Azure portal, and it's sensitive data that should be handled securely.

    Remember to choose an appropriate Istio Helm chart version that matches the capabilities of your AKS cluster.

    To execute this Pulumi program, you would typically go through the following steps in your command line interface (make sure Pulumi CLI is installed):

    1. Create a new Pulumi TypeScript project if you haven't done so already:
      pulumi new typescript
    2. Install the necessary Pulumi Kubernetes package using npm:
      npm install @pulumi/kubernetes
    3. Copy the provided TypeScript program into index.ts in the root of your Pulumi project directory.
    4. Replace placeholder values with actual values from your Azure environment.
    5. Run the Pulumi program to provision the resources:
      pulumi up

    This program will invoke Pulumi to deploy the Istio Helm chart onto your AKS cluster, and you can then configure Istio as needed for your applications running in AKS.
