1. Deploy the dotnet-app helm chart on Opensshift


    To deploy a Helm chart on an OpenShift cluster using Pulumi, we will need to use the kubernetes package, which provides a comprehensive API for managing Kubernetes resources, including Helm charts through the kubernetes.helm.v3.Chart class.

    Below, you'll find a step-by-step guide on how to create a Pulumi TypeScript program that deploys the dotnet-app Helm chart to an OpenShift cluster. OpenShift is essentially a Kubernetes distribution, so the Kubernetes package in Pulumi is suitable for this task.

    Here are the steps that the program will carry out:

    1. We will define an instance of kubernetes.helm.v3.Chart, which represents a Helm chart resource in a Kubernetes cluster.
    2. The Helm chart's chart property will refer to the dotnet-app chart. You need to have access to the chart's repository or have it locally for Pulumi to deploy it.
    3. We'll set the namespace to deploy the chart into a specific namespace in OpenShift if desired; otherwise, it will use the default namespace.

    Before starting, ensure that you have the Pulumi CLI installed and you're logged into an OpenShift cluster with kubectl configured to point to the cluster. You'll also need to have Helm installed if you are going to use a chart from a local path or need to add private repositories. This Pulumi program assumes that kubectl is authenticated to an OpenShift cluster and that the Helm chart is accessible.

    Here's the Pulumi program in TypeScript:

    import * as kubernetes from "@pulumi/kubernetes"; // Create an instance of the kubernetes.helm.v3.Chart class to deploy the dotnet-app Helm chart. // Make sure that the repository where the dotnet-app chart is located is added to your Helm CLI. // If the chart is in a public repository such as Helm Hub or your Helm has access to OpenShift's chart repository, specify it in the 'repo' property. const dotnetAppChart = new kubernetes.helm.v3.Chart("dotnet-app", { // Replace with the actual chart name, if different. chart: "dotnet-app", // Specify the chart version if needed. Omit this if you want to use the latest version. // version: "1.0.0", // Specify values to customize the deployment, if necessary. // values: {}, // You should already have a namespace created in your OpenShift cluster or you can manage // namespaces using Pulumi Kubernetes provider as well. namespace: "default", // Set this to the namespace where you want to deploy your chart. // If the chart is not in a public repository, you can specify fetch options such as 'repo' or 'path'. // For example, you might have a private repository or a local path where the chart lives. // fetchOpts: { // repo: "http://example.com/custom-charts", // }, }); // Export the chart's name and namespace, it will provide outputs once the Pulumi program is deployed and can be used to reference the deployment. export const chartName = dotnetAppChart.metadata.name; export const chartNamespace = dotnetAppChart.metadata.namespace;

    This program defines a new Helm chart resource using Pulumi's Kubernetes provider. Replace "dotnet-app" with the actual chart name if it is different or the chart is located in a different repository or a local path.

    To deploy this chart to your OpenShift cluster, save the above TypeScript code in a file named index.ts. Ensure you have @pulumi/kubernetes package installed in your Node.js project:

    npm install @pulumi/kubernetes

    Then, run pulumi up from the command line in the same directory as your index.ts file. Pulumi will perform the deployment, and you'll see output in the terminal indicating the progress and result. After the deployment, the exported constants chartName and chartNamespace will be displayed with the actual values that can be used to interact with the Helm chart deployment in your OpenShift cluster.

    Remember to check the chart-specific configurations and customize the values property in the Chart resource options as required for your deployment needs.
