1. Deploy the openshift-namespaces helm chart on Opensshift


    To deploy the openshift-namespaces Helm chart on an OpenShift cluster using Pulumi, you will be utilizing the kubernetes.helm.v3.Chart class from Pulumi's Kubernetes provider. This class allows you to deploy Helm charts to your Kubernetes or OpenShift cluster.

    Below is a program written in TypeScript that demonstrates how you would use Pulumi to deploy a Helm chart representing multiple namespaces in an OpenShift environment. Before you proceed, make sure you have the OpenShift CLI tool (oc) configured to access your OpenShift cluster, and you've installed Pulumi and logged in.

    The key steps that the program performs are:

    1. Import required Pulumi and Kubernetes packages.
    2. Create a new Helm chart resource openshift-namespaces from the kubernetes.helm.v3.Chart class.
    3. Specify the chart name (assuming it is openshift-namespaces), its version (optional, if you want to use a specific version), and any custom values you wish to override within the chart (represented as an object in the values property).

    Here is the TypeScript program implementing these steps:

    import * as k8s from '@pulumi/kubernetes'; // Define the settings for the Helm chart. const chartName = "openshift-namespaces"; // Replace with the correct Helm chart name const chartVersion = "1.0.0"; // Replace with the desired chart version, if known const namespace = "default"; // Replace with the target namespace for deployment // Deploy the Helm chart. const helmChart = new k8s.helm.v3.Chart(chartName, { chart: chartName, version: chartVersion, namespace: namespace, // Assuming the Helm chart requires some custom values, provide them in the values object. // Replace this with actual values required by the 'openshift-namespaces' Helm chart. values: { // exampleValue1: "value1", // exampleValue2: "value2", // Add other custom values as needed }, }, { // This option protects against unintented updates to resources managed by this Helm chart. protect: true }); // Export the base URL for the Helm chart, which is useful for debugging purposes. export const chartBaseUrl = helmChart.getResourceProperty("v1/Service", `${namespace}/${chartName}`, "status").apply(status => status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname);

    This program initializes a Helm chart resource using Pulumi's Kubernetes provider. The new k8s.helm.v3.Chart syntax is creating a new instance of the Helm chart. The first argument is the local name used to refer to the chart in the code. The second argument is an object with settings, which includes the chart name, optional version, the target namespace, and any chart values you want to override.

    The values field within the Helm Chart is where you would add any necessary values that configure the Helm chart to your needs. Typically, these would map to the values found in a Helm chart's values.yaml file.

    Before running the Pulumi program, you will need to install the @pulumi/kubernetes package using npm, if you haven't already done so:

    npm install @pulumi/kubernetes

    After the program is ready, you can run it with Pulumi CLI commands pulumi up to preview and deploy your infrastructure. Pulumi will provide a detailed preview of all the Kubernetes resources that will be created by the Helm chart and, upon confirmation, will provision the resources in your OpenShift cluster.

    Please keep in mind that this is a generalized Pulumi program and you'd need to adjust the chartName, version, and values fields to reflect the specific Helm chart you're deploying and the configuration values it expects.
