1. Deploy the istio-ingress helm chart on Kubernetes


    To deploy the Istio Ingress Helm Chart on Kubernetes using Pulumi, we will use the kubernetes.helm.v3.Chart resource from the Kubernetes provider. This resource allows you to deploy Helm Charts within your Kubernetes cluster. Helm is a package manager for Kubernetes, which packages multiple Kubernetes resources into a single logical deployment unit called a Chart.

    Pulumi works with existing Helm Charts by invoking the Helm tool under the hood, but it also provides additional benefits such as stronger integration into the Pulumi ecosystem and improved status monitoring. The Helm Chart resource in Pulumi requires you to specify the chart details such as name, version, repository, and any custom values you want to override.

    Here's the Pulumi program that deploys the Istio Ingress Helm Chart on Kubernetes:

    import * as k8s from "@pulumi/kubernetes"; // Create a new Helm Chart for Istio Ingress. const istioIngressChart = new k8s.helm.v3.Chart("istio-ingress", { chart: "ingress-nginx", version: "3.34.0", // Specify the version of the Helm chart. fetchOpts: { repo: "https://kubernetes.github.io/ingress-nginx", // Replace with the correct repository for Istio if necessary. }, // Optionally, you can override the default values in the Chart // by providing a 'values' object. values: { controller: { publishService: { enabled: true, }, }, }, }); export const ingressServiceName = istioIngressChart.getResourceProperty("v1/Service", "istio-ingress/ingress-nginx-controller", "metadata.name");

    In this program:

    • We import the @pulumi/kubernetes package which provides the Pulumi Kubernetes SDK.
    • We declare a constant istioIngressChart and create an instance of k8s.helm.v3.Chart. This is the primary resource that represents a Helm Chart in the Pulumi Kubernetes ecosystem.
    • The chart property sets the name of the Helm chart to deploy. In our case, it's "ingress-nginx". You'll need to set this to the actual chart name for Istio Ingress if it's different.
    • The version property specifies the exact version of the chart we want to deploy. Please replace "3.34.0" with the correct version of the Istio Ingress chart you'd like to use.
    • fetchOpts.repo is set to the repository URL where the chart is hosted. For Istio Ingress, you may need to replace this with the appropriate URL.
    • In the values object, you can specify any overrides to the default configuration of the chart. This part is optional and specific to your requirements. We've provided an example override that enables the publishService setting under the controller key.

    Lastly, we export ingressServiceName, which gets the name of the Ingress service created by the Helm chart. This is helpful if you need to refer to the service name elsewhere in your Pulumi program.

    Before running this Pulumi program, ensure that your Kubernetes context is correctly configured and pointing at the cluster where you want to deploy Istio Ingress. Also, you should have Helm and Pulumi CLI installed on your local development machine. To run your Pulumi program, you would execute pulumi up, which will initiate the deployment process defined in the program above.

    Please adjust the version, chart values, and repository URL according to the actual Helm Chart for Istio Ingress that you wish to deploy.
