1. Deploy the istio-ingress helm chart on Opensshift


    To deploy the Istio-Ingress Helm chart on an OpenShift cluster using Pulumi, you will be using the Helm Chart resource from the Pulumi Kubernetes Provider. This provider allows you to define and create Kubernetes resources using Pulumi's Infrastructure as Code approach.

    Here's what you need to follow to deploy the Istio-Ingress Helm chart:

    1. Pulumi Kubernetes Provider Setup: You need to have the Pulumi Kubernetes provider configured to communicate with your OpenShift cluster. This typically involves setting up the kubeconfig file that provides the necessary details to connect to your OpenShift cluster.

    2. Using Helm Chart Resource: You'll be using the Chart resource from the Pulumi Kubernetes provider, which is a representation of a Helm chart that can be deployed to the Kubernetes cluster. It uses the Helm CLI's deployment logic under the hood.

    3. Configuring Chart Values: If you need to set any configurable values for the Istio-Ingress chart, you can specify those in the values property of the Chart resource.

    Below is a TypeScript program that uses Pulumi to deploy the Istio-Ingress Helm chart on an OpenShift cluster:

    import * as k8s from "@pulumi/kubernetes"; const istioIngressChart = new k8s.helm.v3.Chart("istio-ingress", { chart: "istio-ingress", version: "1.6.0", // specify the exact chart version fetchOpts: { repo: "https://istio-release.storage.googleapis.com/charts", }, // Assuming you have set correct values specific to your Istio-Ingress configuration // Replace with your actual values or configurations values: { // For example, enable ingress gateway gateways: { istio-ingressgateway: { enabled: true, }, }, // Further configurations can be added here as needed }, }); // Export the resources created export const ingressGateway = istioIngressChart.getResource("v1/Service", "istio-system", "istio-ingressgateway");


    • First, we import the @pulumi/kubernetes module which contains the logic needed to interact with Kubernetes clusters.

    • Next, we instantiate a new Chart object from the Pulumi Kubernetes provider. The chart name is "istio-ingress". This is the logical name that Pulumi will use to reference the Helm chart in its state.

    • We specify the chart version to use. It is important to pin the chart to a specific version to ensure that the deployment is repeatable and stable.

    • The fetchOpts.repo setting points to the Helm repository where the Istio-Ingress chart is hosted.

    • values is an object containing the configuration for the Helm chart. This should be configured depending on the particular needs of your Istio Ingress setup. In the example, we enable the Istio Ingress Gateway.

    • Finally, we export a reference to the Istio Ingress Gateway Service, which you can use to interact with the service, such as obtaining its external IP, after deployment.


    • Make sure that the Helm repository URL provided in fetchOpts.repo is the correct one for the Istio-Ingress helm chart you intend to deploy. The URL given in the code snippet is hypothetical and provided as an example.

    • The Helm chart's version (version: "1.6.0") should be the actual version you want to deploy. Replace it with the correct version number.

    • The values provided need to match with your configuration requirements for the Istio-Ingress installation. You may need to adjust these settings based on your Istio and OpenShift setup.

    By running this Pulumi program, you can deploy the Istio-Ingress Helm chart to your OpenShift cluster. You would run the Pulumi CLI commands (pulumi up) to preview and apply the changes described by the TypeScript program. After the deployment, you'll have Istio-Ingress set up and ready to handle ingress traffic for your OpenShift cluster's services.
