1. Deploy the httpd helm chart on Kubernetes


    To deploy the httpd Helm chart on a Kubernetes cluster using Pulumi, you'll use the @pulumi/kubernetes package, which allows you to interact with Kubernetes resources within your Pulumi program. In this case, you'll use the Chart resource, which represents a Helm chart. The httpd chart will be deployed in your cluster.

    The following program does the following steps:

    • Imports the necessary Pulumi packages for Kubernetes.
    • Creates a new Helm chart resource for httpd.
    • Specifies the chart version (optional) to ensure that you are using the exact version you want.
    • Provides a namespace for the deployment (optional).

    Here's a detailed Pulumi TypeScript program that you can use to deploy the httpd Helm chart on your Kubernetes cluster:

    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes Namespace const namespace = new k8s.core.v1.Namespace("httpd-namespace", { metadata: { name: "httpd", }, }); // Deploy the httpd Helm chart into the created Namespace const httpdChart = new k8s.helm.v3.Chart("httpd", { namespace: namespace.metadata.name, chart: "httpd", // Optionally specify the version of the Helm chart to use // version: "X.Y.Z", // Add any custom Helm values here if needed values: { // Custom values go here }, }); // Export the public Service endpoint if httpd chart provides one export const httpdEndpoint = httpdChart.getResource("v1/Service", "httpd", "httpd").status.loadBalancer.ingress[0].hostname;

    Let's break down what this code does:

    • It imports the Kubernetes package from Pulumi, which provides the needed classes and functions.
    • It creates a new Kubernetes namespace specifically for the httpd deployment. Namespaces help organize clusters and can isolate resources from each other.
    • It declares a Helm chart resource called httpdChart using the Chart class. The chart is fetched from the public Helm chart repositories.
    • It optionally allows you to specify the version of the Helm chart you want to deploy with the version key, which can be important for ensuring consistent deployments.

    Remember to install the required Pulumi packages first by running npm install @pulumi/kubernetes.

    To launch this deployment, save the code to a file named index.ts, and then run pulumi up from the same directory. Pulumi will interact with your configured Kubernetes cluster and deploy the httpd Helm chart according to the code above.

    Finally, the program exports the endpoint of the httpd service, which you can access through your browser or API calls to interact with the deployed httpd instance. This export assumes that the Helm chart exposes a LoadBalancer service that becomes publicly accessible if your cluster supports it. If your deployment is internal or uses a different service type, such as ClusterIP or NodePort, you'll need to adjust the export accordingly.
