Deploy the unauthenticated-ingress helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy an unauthenticated Ingress Helm chart on a Kubernetes cluster using Pulumi, you will use the kubernetes.helm.v3.Chart resource, which is part of the Pulumi Kubernetes provider. This resource allows you to deploy a Helm chart within your Pulumi program, leveraging the wide array of existing Helm charts for different applications.

Below, we are going to write a Pulumi program in TypeScript to deploy the unauthenticated-ingress Helm chart. If this is a specific chart, then you must ensure the chart is available in a Helm repository. If it's not a well-known public chart, you'll need to upload the chart to a reachable Helm repository or have the chart files locally.

Here are the main steps that the following program will do:

Import the @pulumi/kubernetes package to provide the Kubernetes resources.
Create a new instance of Chart that references the unauthenticated-ingress chart.
If necessary, configure the chart values depending on your use case.
Export any relevant resulting resource properties, such as the Ingress endpoint.

First, you would need to install the necessary Pulumi package for Kubernetes by running npm install @pulumi/kubernetes.

Here's the Pulumi program that deploys the unauthenticated Ingress Helm chart:

import * as k8s from "@pulumi/kubernetes";

// Replace these values with the appropriate information for the unauthenticated-ingress Helm chart.
const chartName = "unauthenticated-ingress"; // The name of the Helm chart you wish to deploy.
const chartVersion = "1.0.0"; // Replace with the chart's version you wish to deploy.
const helmRepoUrl = "https://charts.example.com/"; // The Helm chart repository URL.

// Deploy unauthenticated-Ingress Helm chart using Pulumi Kubernetes provider.
const ingressChart = new k8s.helm.v3.Chart("unauthenticated-ingress", {
    chart: chartName,
    version: chartVersion,
    // If the chart is from a repository other than the default Helm repo,
    // specify the repository URL like below.
    // Otherwise, you can omit the "fetchOpts" field.
    fetchOpts: {
        repo: helmRepoUrl,
    },
    // If the chart requires specific configuration, set them within the 'values' block.
    // Otherwise, if no custom configuration is needed, you can omit the 'values' field.
    values: {
        // Example configuration (you will need to change these according to your chart's values)
        // service: {
        //   type: "ClusterIP",
        // },
        // Ingress settings might go here
    },
});

// If you need to reference any of the resources created by the Ingress chart
// (For example, to export the Ingress' external IP), you would access it here.
// Example (syntax may vary depending on the Helm chart's outputs):
// export const ingressEndpoint = ingressChart.getResourceProperty("v1/Service", "<resource-name>", "status").apply(status => status.loadBalancer.ingress[0].ip);

// The above 'getResourceProperty' method would be used if you need to extract a specific property from a resource managed by the Helm chart.
// Replace "<resource-name>" with the actual name of the resource provisioned by the Helm chart, which might be available in the chart's documentation.

// Running `pulumi up` will execute the program and perform the deployment based on your Pulumi and Kubernetes configurations.

This program starts by importing the necessary Pulumi Kubernetes package and then creates a new Helm chart resource to deploy. You must replace chartName, chartVersion, and helmRepoUrl with the appropriate values for the Helm chart you are deploying. If your chart requires certain configuration values, specify them within the values object.

Once everything is set, run pulumi up within your Pulumi project directory to initiate the deployment to your Kubernetes cluster. The Pulumi CLI will display the progress and results of the deployment.

Keep in mind that to run this Pulumi program, you must have access to a Kubernetes cluster and have your kubeconfig file configured correctly. Additionally, ensure that Pulumi is installed and configured for use.

Please replace placeholders and configurations with those specific to your need. If unauthenticated-ingress is not an actual Helm chart or has different parameters, you will need to adjust the settings accordingly.
