1. Deploy the contour-operator helm chart on Opensshift


    Deploying a Helm chart on an OpenShift cluster involves a few steps that are quite similar to deploying on a standard Kubernetes cluster. You'll need to set up a Pulumi project with the correct configuration to interact with your OpenShift cluster. Since OpenShift is Kubernetes-based, we can use Pulumi's Kubernetes Provider to manage resources in an OpenShift cluster.

    In this scenario, we want to deploy the contour-operator Helm chart. Contour is a Kubernetes ingress controller using Envoy proxy.

    Here's a step-by-step on how to deploy this Helm chart onto OpenShift with Pulumi:

    1. Ensure that you have access to your OpenShift cluster and your kubeconfig is correctly set up.
    2. We’ll be using the kubernetes package in Pulumi to interact with the OpenShift cluster.
    3. We'll instantiate a Chart resource in Pulumi, specifying the contour-operator Helm chart's repository URL and the chart name.
    4. The Chart resource will be the representation of our Helm release within the Pulumi program.

    Here is the TypeScript program that performs these actions:

    import * as k8s from "@pulumi/kubernetes"; // Define the repository URL for the helm chart. const repoURL = "https://projectcontour.io/contour-operator/"; // Create a helm chart resource for the contour-operator, // specifying the version and chart name, along with any other necessary parameters. const contourOperatorChart = new k8s.helm.v3.Chart("contour-operator-chart", { repo: repoURL, chart: "contour-operator", // You might need to specify the namespace where you want to deploy your Helm chart namespace: "your-namespace", // Replace with the actual namespace values: { // Custom values you want to override in the Helm chart }, // Other parameters like version can also be specified if needed. }); // Export the name of the chart we just deployed export const chartName = contourOperatorChart.metadata.name;

    Make sure to replace "your-namespace" with the namespace where you want to deploy the contour-operator chart.

    Important Notes:

    • This program assumes you've already got your Kubernetes Pulumi provider configured to target your OpenShift cluster. If not, you might need to set up the provider with the path to your kubeconfig or with the appropriate context if it's different from the default.

    • values is set as an empty object in this example, but you could add any configuration overrides that are specific to contour-operator as key-value pairs within that object.

    • namespace should be set to the namespace where you wish to deploy your contour-operator. If the namespace doesn't exist, you might need to create it using Pulumi before deploying the chart or set the createNamespace option to true as part of the ChartOpts.

    • The Chart resource encapsulates the deployment of a Helm chart as a first-class Pulumi resource. This includes capabilities like reporting the status back to Pulumi and full support for previews and updates.

    Remember to run pulumi up in your Pulumi project directory to deploy the resources defined in this program. This command will build your Pulumi program, show you a preview of the changes it will make to your infrastructure, and prompt you to confirm these before proceeding with the deployment.
